A patient of mine recently sent me this message – I was briefly shocked for a brief second, but then agreed! It is known that alcoholic mouthwash can pose a health risk to your body (and even cause cancer), but I never thought a product marketed as “safe” would actually kill mosquitoes!
“Dr. Sun, I was at a deck party awhile back, and the bugs were having a ball biting everyone. The host at the party sprayed the lawn and deck floor with Listerine, and the little demons disappeared. The next year I filled a 4-ounce spray bottle and used it around my seat whenever I saw mosquitoes. And voila!”
This little anecdote really makes you think twice about using alcoholic mouthwash! Ethanol contained in some mouthwash rinses dramatically increase the ability of cancer-causing substances to penetrate the lining of your mouth, and other harmful chemicals such as Acetaldehyde – which forms in a person’s mouth after using alcoholic mouthwash – are suspected to be carcinogenic. These chemicals are not only harmful to the body, but as we’ve learned, are strong enough to kill certain organisms, which should make you think twice about using alcoholic mouthwash!
If you are concerned about cleaning your mouth with a rinse, try a non-alcoholic alternative which is often natural, safe and just as effective as an alcoholic mouthwash. My favorite is Tooth & Gum Tonic. If you have any questions about mouthwash or how to find an effective and safe rinse, consult with your dental professional!
Getting a good night’s sleep is one of the most fundamental rules of good health. Getting 7 to 8 hours every night not only rejuvenates you for tomorrow’s activities, but sleep is essential for a well functioning immune system! Improper sleeping habits can also affect your oral health, including grinding and jaw problems which can lead to severe issues down the road.
A good night's sleep is essential for your health!
When trying to understand your sleeping habits, it is essential to understand the difference between REM and non-REM sleep. REM, which is short for rapid eye movement, accounts for about 1/5 to 1/4 of a typical person’s total sleep in a night, and is characterized by a rapid flickering of the eyes, irregular breathing, major voluntary muscle paralysis and decrease in body temperature. It is high in brain activity and it is when most of our dreaming occurs. REM sleep is the fifth and last stage of sleep that occurs in the sleep cycle, which repeats itself about five times throughout a period of sleep. It is preceded by four stages of non-REM sleep. The 3rd and 4th stages of NREM sleep are the deep sleep stages, there is evidence that brain cells reset their sodium and potassium level during this deep sleep, and in fact the body repairs and regenerates tissues, builds bones and muscle, and strengthen the immune system during this stage!
Usually the deep sleep represented with Delta waves in brain activity are long, slow undulating waves. Certain frequencies in the Delta range trigger the release of Human Growth Hormone and are thus beneficial to healing and regeneration. Quality sleep by definition must include deep sleep, which is the deepest, first cycle of your sleep – synchronizing your sleep with your body’s natural sleep cycle will help you obtain better quality sleep. For most of people, going to bed before 11 PM would follow the body’s natural biological rhythms. Your body’s call for sleep is essential, we need it to stay healthy.
Bruxism (grinding and clenching your teeth during sleep) is brought up with the contraction of your jaw muscles, which most intensively happens at the 2nd NREM sleep cycle stage, moving in and out of the REM cycles. If you don’t go to bed on time every night, or your sleep pattern gets interrupted repeatedly, you will not be able to get into the restful stage 3 and stage 4 sleep that your body needs. You will end up getting more of the shallower stages of sleep, and going through more clenching and grinding. As we have learned, the consequences of excessive force bought up with clenching and grinding of the teeth can lead to excessive wear on our teeth, breaking up dental restorations, overloading the mouth’s supporting structure, gum recession and even TMJ symptoms, if these destructive forces are not properly managed. Of course, we should all work on establishing healthier lifestyles, and better rest. We can also work on better diet and cutting back on stimulants at night that can interrupt your sleep cycle. Having a custom-fitted nightguard made from your dentist might also be an idea worth exploring – consult with your dental professional, and stay healthy!
What do Olympic divers, your local swim instructor and you – if you’re a swimmer – all have in common? Apart from a love for the water, exercise and the sport, there is a common risk of developing dark yellow or brown stains on the teeth of all avid swimmers who spend at least six hours a week in the pool!
The Academy of General Dentistry (AGD) has recently concluded a study on athletic swimmers who swim laps more than six hours a week, which has shown that exposure to chemically treated pool water can cause organic deposits to form on the teeth of these swimmers. Pool water is routinely treated with chemicals to keep the water clean for swimming, but these chemicals inadvertently raise a pool’s pH level to a level more basic than saliva (higher pH). By opening the mouth and exposing your teeth to pool water which contains antimicrobial chemicals, the water causes salivary proteins to break down and form deposits on teeth.
Why does this matter? Unfortunately, as deposits are formed on swimmer teeth, calculus buildup – hard, brown tartar deposits – appear predominantly on the front teeth and can be difficult to remove. Apart from keeping the mouth closed while swimming, avid swimmers should have their teeth professionally cleaned up to twice as often as non-swimmers (approximately four times a year). In addition to calculus deposits, the pool area can be a dangerous place for the mouth. When coming to the surface of a pool, rise gracefully! Many people hit their front teeth on a pool ledge, which can cause serious damage to the teeth and supporting jaw. Slippery pool decking can also cause falls which often chip , break or severly damage your teeth or mouth. Take precaution, be safe and healthy, but enjoy and have fun with swimming – it’s a great exercise and a lifetime sport that benefits the body and the whole person !
Swine Influenza H1N1, more commonly known as Swine Flu, has continued to grow and expand worldwide over the past week, and concerns are (rightly) high about how we can stay healthy and safe. The World Health Organization may even declare swine flu a pandemic! Apart from not gathering in large groups and washing your hands, is there any way you can stay safe?
Transmission of the virus is from human-to-human contact, and all reported cases worldwide have stemmed from some sort of exterior human interaction. A high-running fever (over 100* Fahrenheit), fatigue, headache, vomiting, diarrhea and respiratory problems are among the most common symptoms of having the virus. In attempting to prevent transmission of this virus, be sure to wash your hands frequently and always cover your mouth, preferably with tissues or your forearm instead of your hands when coughing or sneezing (especially if you are in a doctor or dentist office).
Now, how to protect yourself and your loved ones from getting the swine flu or any flu: prevention rules.
1. The first step to fight any flu is prevention. Stay away from people who have caught any disease or have symptoms of it. Avoid public restrooms at all costs. Wash your hands after you touch any public door knobs or hand rails, and wash your hands before you touch your toothbrushes or contact lenses. Use hand sanitizer.
2. Boost your immune system. A healthy lifestyle is always beneficial for your overall health. Eat a proper diet rich in fruits, vegetables and lean proteins, keep yourself well hydrated, exercise, get a good night’s sleep, and keeping a positive attitude are all important. Regarding alternative remedies to boost the immune system and against flu, consider garlic. Cooked garlic has less odor, or you can cut up small pieces and swallow like a pill, or take it in a pill form. Cloves, oregano oil, zinc, echinacea, and vitamin c are few suggestions.
If you are noticing any respiratory problems or prolonged flu symptoms and are running a temperature, schedule a visit with your primary health care physician. Brush and floss twice daily, and after meals (a clean mouth prevents introducing pathogens into your system). If you have a sore throat, gargle with warm salt water and increase your vitamin c intake to around 2000 mg/day. Limit your bad habits like alcohol drinking, smoking as well as your soda intake! Treat your body well and it will do its best to fight outside invaders.
Most people are well aware of soda’s detrimental effects on the teeth (including erosion and bone loss) – but it also is addictive?
The allure of diet soda is obvious for people who are conscious about their figure: it tastes great, it’s refreshing, and has few or no calories. Unfortunately, most of us don’t realize how dangerous the other ingredients in soda really are, even with no sugar. Many diet cola drinkers have a false sense of security that their diets will be successful drinking diet soda, and actually consume more calories because of it. Putting aside the acidic problems with soda and the havoc they wreak on your teeth, gum and bone, let’s look at the caffeine aspect of cola. All dark colas are full of artificial chemicals which can degrade your skin and internal organs over time, but those which are caffeinated present an addictive factor as well. Caffeine addiction can make a person feel downright ill if they don’t receive their “soda fix” – muscle pains, headaches and nervousness are common among soda addicts, and are known as symptomatic withdrawal. Even though withdrawal symptoms are most commonly associated with tobacco and hard drugs, caffeine falls into the addictive drug category as well. Johns Hopkins University, the authoritative leader on mental disorders in the medical world recognized “Caffeine Withdrawal” as an official disorder in 2004. Symptoms usually occur within 12 – 24 hours of halting caffeine intake, and can last for days.
In addition to the caffeine addiction problem with all soda, recent studies have shown that drinking even just one soda a day can raise a person’s risk of developing metabolic syndrome by 48%. Metabolic syndrome drastically increases the likelihood for heart disease and diabetes. Phosphoric acid found in any dark cola is another leading contributor to bone loss among soda drinkers. Combined with the high withdraw rates of caffeine addiction and the problems associated with caffeine withdraw (disturbed eating and sleeping patterns, anxiety and restlessness), drinking even moderate amounts of soda in a day-to-day routine can produce drastically negative effects on a person’s health. This does not even address the detrimental effects of cola acidity on oral health.
In North America, a continent in which 80 – 90% of all adults drink some form of caffeine on a regular basis, this epidemic of sorts has reached maximum capacity. Save your body and your mind – kick the soda habit! You will feel more rested and relaxed throughout your day, your concentration ability will increase and you will be doing a great service to your osteo (bone) and oral health. Drinking diet soda does not guarantee your diet will be successful, and in the long run, will in fact make your body’s health deteriorate. If you must drink diet cola, be sure to drink in moderation! Small amounts, 8oz or less, only once a day! Think about the chemicals and caffeine in the cola you drink, you might think twice!
“Doc, can I have more Novocaine? I don’t feel very numb.” Of course, it is nice to feel numb before dental surgeries! Have you ever been in a situation in which you had difficulty getting numb?
Local anesthetic is effective in most situations, however approximately 15% of dental patients experience a partial or total lack of numbness after receiving anesthesia injections. This phenomenon usually occurs in the lower jaw, when mandibular bone is too dense for infiltrated anesthetic injections to take, unlike the upper jaw which can receive the anesthetic solution easily. The dental nerve within the lower jaw is essentially buried within the dense bone itself, so it requires a mandibular block injection for proper numbing (numbing which includes the teeth, tongue and lips in the same quadrant).
Variations in the anatomy of the “entry window location” (where the mandibular injection deposits its solution) makes it difficult for some people to receive proper numbing, even when the dentist follows the usual landmarks – don’t blame the dentist right away if your anesthesia doesn’t work! The physiology of each individual varies besides the anatomy, which will lead to different thresholds or reactions to various dental injections. Different dental injection solutions also gives different numbing effects – your dental professional should choose what is most applicable to your situation, usually epinephrine (the blood vessel constrictor) is added to give a better local numbing effect.
Speedy injections or anxious patients can cause a racy heart beat, which could be very uncomfortable. If you’ve had too many cups of coffee or if your blood sugar is low from having not eaten, you may feel uncomfortable after receive the dental injection. The wine from last night can also alter the effectiveness of the numbing. This all makes anesthesia a very delicate science. The technique of the operator (the dental professional) can occasionally be at fault for improper anesthesia, but more likely than not it is a complication with a patient variable. It is important for you to communicate with your dental professionals if you’ve had a history of difficulty with dental anesthetics.
Special oral local anesthetic techniques, such as intraosseous anesthesia, which can enhance deep pulpal anesthesia, may help to increase the numbing sensation. This process injects novocaine directly into the bone marrow – because the needle penetrates the hard cortex of the bone, it penetrates to the jaw’s deepest level and can adequately numb the site. It is important to remember that every mouth can be anesthetized, however because intraosseous anesthesia is considered a specialized procedure, it is important to find a dental professional who is experienced with such techniques.
Do you need some extra cash, especially if you are feeling the squeeze of the credit crunch? Check your drawers and jewelry boxes to find any gold crowns or inlays removed from your mouth, trade in the dental scrap for some pocket change!
Gold fillings are removed
You might have never thought about it, but gold fillings, bridges and other gold dental work is actually worth some money in today’s economy! Gold is one of the few precious metals which has held its value, and many people with scrap fillings lying around the house are turning to jewelers to get money for their gold dental work! They can sell for $30 to $50.
In our office, when offered remaining gold scrap when a patient has old dental work removed, 25% of people say they would like to keep the gold. Some people have these gold teeth lying around, and if you fall under this category, it might be time to change the gold dental scrap to good use. Gold does not corrode in the harsh oral environment, and because of this, it has been a suitable restorative material choice for decades (even though in more recent years, the trend has been towards composite or porcelain material which looks natural against other real teeth). Still, there is plenty dental gold work even today, and even porcelain crowns can be supported with dental gold alloy. While dental gold is usually 12 to 16 karat, not 24 karat, it still fetches a high resale value, up to $900 per ounce in today’s economy! The gold must be treated chemically to remove other metallic substances, but this can be easily done by the jeweler you sell your scrap gold to.
There is one shocking fact you learn from this dental gold rush story – the base tooth is actually separated from the gold cap with your cola drink. Cola is no stranger to criticism from the dental world, its acidic properties can erode your enamel and gum (and even lead to bone loss!) and can wreak havoc in your mouth. If you soak the tooth in a cup of cola for 24-48 hours, the gold cap will separate from the tooth and will be ready for scrapping. Doesn’t this fact make you think twice about drinking cola? The best way to fight recession is get into prevention, take good care of yourself! When you’re healthy, it’s much easier to be productive and move ahead. Let your mouth be your asset instead of liability starting with proper home care and stay away from bad habits and poor diets.
” May I have some laughing gas please?” is a popular request among the “high anxiety” or “wants to get away” group.
A patient is anesthetized with nitrous oxide.
Nitrous oxide gas (nitrous oxide and oxygen (N20-02)) is affectionately known as “laughing gas” due to its euphoric qualities when inhaled. Discovered in 1772 by Humphrey Davy, he had this to say about its effects: “On the day when the inflammation was the most troublesome, I breathed three large doses of nitrous oxide. The pain always diminished after the first four or five inspirations; the thrilling came on as usual, and uneasiness was for a few minutes swallowed up in pleasure.” When the gas is inhaled (at an approximately 50% nitrous oxide + 50% oxygen dilution), after several minutes nearly all pain dissipates from the body and a euphoric warmth spreads throughout the body. This pleasant feeling is not only pain-reducing, but can calm anxious nerves and relax all but the most fearsome patients. The calming, relaxing and euphoric qualities of nitrous oxide make it a prime candidate for anesthetizing patients who have irrational fears about dental procedures who are unable to get comfortable in the chair. Because laughing gas can be highly effective in treating moderate dental anxieties, nitrous oxide gas can also benefit the dental physician working on a patient – calm environments benefit everyone! Patients with high blood pressure, or who have had heart attacks in the past and are at risk from traditional IV anesthesia are prime candidates for nitrous oxide sedation.
The level of sedation and warmth felt in the body after inhaling nitrous oxide gas depends on the concentration of the dosage, and how long the gas is administered. Because the gas is administered into the lungs, it is saturated into the blood stream very quickly and once the procedure is finished, there are no lingering “hangover” effects, meaning it is safe to drive home without an escort. Local anesthesia is still necessary for the treatment site, but needle-phobia will disappear with laughing gas. If you suffer from dental anxieties and have tried different techniques, seen different dentist and you still can not face dental work with ease, it is worth while for you to try nitrous oxide during your next dental procedure. Have a discussion with your dental professional.
Mark came in with a severe tooth ache, and after an examination, I could see the tooth was severely broken down. The basic options were to either save the tooth – going through root canal therapy and finishing with a post and crown restoration, or to remove the tooth and restore with a dental implant and crown. “Should I save my tooth, or should I pull it!” This is the eternal question!
Root canal therapy (also known as endodontic therapy) is a procedure of treatment for the pulp of a tooth once it has become infected – the inner pulpal material must be removed, in order to protect and decontaminate the tooth from future microbial invasion to the jaw bone. Once a root canal procedure is performed, however, the lack of nutritional supply in the tooth (once the organic tissue is removed from the tooth during the procedure) will render the tooth brittle, the weakened tooth should be reinforced and restored properly, with a post and crown.
Root canal treatment does have a bad reputation due to the pain and the stigma associated with the procedure. Often times, a patient will have a root canal performed and think the procedure was a success, only to have pain and infection return several years down the line. The complexity of the anatomic root variation could be an obstacle and techniques can often be tedious, which is why specialized service is usually performed by a highly trained dentist or endodontist. Special tools like microscopes are also often necessary for a successful procedure. Advanced instrumentation and technique will ensure long-term success.
Regular dental checkups are vital to properly maintain your dental health. If the unhealthy dental condition requires a root canal treatment or an extraction, have your dental professional explain the pros and cons of each option, then make an educated decision. If there is a mystery pain, a 3-D image (Morita Survey of CT scan) would be invaluable for proper diagnosis. Regular dental x-rays are not capable of capturing images of a cracked tooth nor accessory root canals (which are small and difficult to see). These tiny cracks or canal issues can lead to prolonged discomfort, which you may have thought was a figment of your imagination! If the prognosis was poor, or a tooth has broken down so much that it has become unrestorable, extraction and a dental implant might be a more sustainable investment to you dental health. Prevention is always the best treatment! Brush and floss your teeth twice daily and after meals. If you have any dental pain, schedule an appointment with your dentist sooner rather than later.
When you smile, the corners of the mouth upturn, eyes begin twinkling and positive emotion radiates. A person’s smile is a pleasant, agreeable part of their appearance and facial characteristics; a person’s smile is the window to their heart!
Dental components like teeth and gum do play an important role in a smile. In today’s society, if a person’s dental components are not healthy or if they do not look right, most will feel far less confident to smile. As cosmetic dentistry has come into a heavier demand in recent years, smile design has become a term used for various clinical treatment plans and for aesthetic improvement. This means smile design: projecting an enhanced smile through alteration of dental components as a practice of cosmetic dentistry. This is a type of comprehensive oral care that combines art and science to greatly improve the aesthetic appearance of the smile, as well as its health and function.
Proper smile design starts with a facial analysis, when the line between the pupils and the horizontal line from the connecting edges of your upper teeth (smile line) are [hopefully] in parallel harmony; the smile line should also harmonize with the upper curvature of the lower lip. Then we evaluate the color, size and alignment of the dental compound, whether it is somewhat in the right places and proportional in relation with the face.
Some of the most common cosmetic procedures include tooth bleaching (or whitening) which enhances the color appearance of your teeth, bonding and veneers or porcelain crowns(which can enhance the outward appearance of a tooth’s color or shape), and gum work (like a gingival plasty, gum contouring or crown lengthening) to harmonize with teeth. Straightening of teeth through adult orthodontics are also a part of cosmetic smile design – not only for improvement of the smile, but to set up a healthier foundation for other cosmetic procedures (or simply to make the mouth easier to clean and maintain).
Laser dentistry is very complimentary to cosmetic dentistry. Laser smile design not only makes common procedures like teeth whitening and gum contouring quick and painless, but because of the laser’s highly focused energy path, very little tissue around the site is disturbed. Procedures are very non-invasive.
Ultimately, cosmetic dentistry and laser smile design could be a great investment if you are not comfortable with your smile or the condition of your teeth (especially if they are worn or broken down, requiring rehablitation or reconstruction). Once you present a confident and happy smile, people will smile back at you and many windows and opportunity will open! Give thought to whether it’s time to have a smile analysis and smile design performed by your dental professional.
