“Where is Your Tooth #8?”

Posted by drgracesun on March 5, 2009 under Information | Be the First to Comment

Do you know the names and numbers of your teeth? Can you only say “The pointy one in the top right side!” Let’s get to know your teeth better here; it will make you a better communicator with your dental professional – you’ll even be able to pinpoint specific teeth over the phone!

The universal numbering system, pictured above, identifies each tooth in a person’s mouth with an individual number. This system references all the teeth that should be in your mouth, so if you have wisdom teeth (or other teeth) which have been removed, those numbers still exist. # 1 is your upper right wisdom tooth. Each tooth then progresses up one number all the way across to the 3rd molar (wisdom tooth) on the left side of the mouth (# 16). #17 will be the lower left wisdom tooth, and counting clockwise, the last tooth will be #32, the lower right wisdom tooth.

Because most people do not have 32 teeth, due to wisdom tooth extraction, congenitally missing them or extraction due to un-restorable dental conditions, we will skip over any missing numbers. It is also important to know the names of the teeth! Your front four teeth (7, 8, 9, 10) and your front lower four teeth (23, 24, 25, 26) are incisors. Incisors are mainly used for gripping, cutting and shearing food, and are the first thing a person sees when you flash your smile. Incisors also play a dominant role in speech.

Moving further back are the canines (or cuspids).On the upper jaw, canines are also named “eye teeth” because the long root almost points to the eye socket. They are #6 and 11 (upper jaw) and #22 and 27 (lower jaw). Canine teeth are relatively long and pointed, used primarily for holding food while it is being ripped in the mouth.They are an important guide for the bite of your teeth; usually they are the first to wear away. Once canines are worn, other teeth will wear away quickly.

Behind the canines lie the bicuspids (or premolars),  #4, 5, 12, 13 (upper jaw) and #20, 21, 28, 29 (lower jaw). Bicuspids are a sort of “inbetween tooth,” with the properties of both the canine and molar teeth. These teeth transfer food from the canines to the molars for proper grinding.

Finally, the molars make up the rear-most teeth in your mouth. Depending on if you have your wisdom teeth or not, you will have 8 or 12 molars, which lie directly behind the two biscuspids in each quadrant of your mouth, #2, 3, 14, 15 (upper jaw) and #18, 19, 30, 31 (lower jaw). Molars are like a grinding table, carrying out the smashing and grinding of food for digestion.

Next time, try to communicate with your dental professional the name or number of your tooth that is being discussed. It would impress and earn great respect from your dental professional, and would also be the first step to knowing your teeth! Once you know your teeth better, you will likely find taking care of your dental health easier more interesting. If you learn these numbers, you will be one step ahead of most people regarding dental communication!

“Good candy?!”

Posted by drgracesun on March 4, 2009 under Information, Smart Smile | Be the First to Comment

Imagine being able to suck on a lollipop to benefit your teeth! Imaging a candy approved by your dentist ! A UCLA research team (with Chinese collaboration) has developed a licorice candy which actually destroys the bacteria in your mouth responsible for cavities and tooth decay – without disrupting the healthy, digestive bacteria. Sound amazing? It just might be the future!

Glycyrrhiza uralensis is the magic behind this development, an extract from licorice root which effectively eliminates 99.9% of the mouth’s streptococcus mutans, a significant bacterial contributor to tooth decay (it produces acids which eat away at the protective outer layers of your teeth). The extract, blended into a sugarfree candy lollipop, can be ingested like a normal piece of candy, with no negative side effects noted (at this time). Licorice root also promotes saliva flow, promoting a healthy oral environment. Alternate studies have also shown licorice extract to be capable of relieving pain symptoms associated with canker sores.

Besides the obvious benefits of a convenient, delicious way to fight tooth decay, sugar-free candy produced with licorice root could be a godsend for mothers and parents who can’t get their children to stop eating candy (or who refuse to brush their teeth)! The amount of time it takes for the average person to suck and digest a lollipop was shown to be more than adequate for the root to kill harmful bacteria in the mouth. Chinese medicine has used licorice root for centuries( I grew up in Taiwan, used licorice root for teething, even I had sweet tooth and always rushed with my brushing, did not have cavity problem!) in treating various inflammatory and viral maladies, although western medicine has only recently discovered the benefits of the root.

Although these cavity-fighting candies are only available in Japan and Europe at the moment, it won’t be too long before Americans will be able to prevent cavities with lollipops! More research is necessary before such products will be approved by the FDA.

“What Should I Eat?”

Posted by drgracesun on March 1, 2009 under Information, Smart Smile | 2 Comments to Read

What you eat, and how often you eat foods that are unhealthy for your teeth, determine how likely you are to get cavities and other problems caused by bad diet, like bad breath and even gum disease. As you eat, your mouth begins the first stages of digestion. Healthy bacteria in your saliva convert sugars into acids – good for digestion, bad for your teeth. Plaque is one of the biggest enemies to your mouth, which forms when food particles are allowed to linger around your teeth and gums. This process begins the moment you begin to eat, which is why it is so important to brush and floss after every meal.

A healthy meal for your body and your teeth!

Once a tooth forms, it is subject to our oral environment. Diets consisting of high sugar, starch or acid content can all erode your enamel unless you are exceptionally good keeping up your oral hygiene (brushing and flossing after every meal). The health of gum and bone tissue that supports the teeth is greatly influenced by proper diet that contains nutrients to keep our body healthy.

What should you eat? Natural, organic and unrefined foods. These foods have high nutrient value and less sugar than processed food, and will pose a smaller threat to your teeth. The best food choices include dairy (like milk, cheese and yogurt) and poultry (like chicken and duck). These foods provide your teeth with calcium and phosphorus, which help to form enamel and bone. Crunchy natural foods like  nuts and green leafy vegetables or orange-colored fruits will stimulate gum and saliva flow, a natural cavity fighter. These foods also contain beta carotene, which the body turns into vitamin C (essential for your body’s ability to maintain and repair healthy soft tissue). If you cannot eat fruits and vegetables naturally, taking a supplemental vitamin or drink which contains Vitamin C and other antioxidants will help protect your gums against cellular damage, and promote their healing abilities. Unsweetened tea is another great drink which has little impact on your mouth’s health.

Foods which contain high amounts of sugar (like candy and carbohydrate-laden foods like bread, chips, fries and muffins), natural or processed, are a tooth’s worst nightmare! The high sugar content of these foods help bacteria thrive. Breads and starches should be an occasional indulgence: when starches mix with amylase (a natural enzyme in your mouth), acid forms that erodes the enamel of your teeth. Additionally, dry foods like chips and cookies or even dried fruits have a tendency to stick to the surface of your teeth, which also helps bacteria thrive. Acidic sweetened beverages like sodas are the worst type of liquid to expose your teeth to, and can cause tooth erosion, enamel decay and even periodontitis – avoid soda and carbonated beverages at all costs! Artificial sweeteners can be a better alternative to sugar-sweetened drinks, as they do not feed bacteria like natural sugar.

Pregnant? Start right by eating right during pregnancy. Eating sensibly during pregnancy means getting adequate calcium (your body needs Vitamin D to absorb calcium) to form strong teeth and bone, which will give your child a good start also. Fluoride can also be used to prevent tooth decay.

So, eat more vegetables and fruits, avoid sugary foods and drinks, and remember to brush, floss and rinse your mouth (and tongue) after meals. You will be on the road to healthy, brilliant teeth!

“How Do I Get Kissable Breath?”

Posted by drgracesun on under Healthy Smile, Information | Be the First to Comment

Halitosis, or bad breath can affect a person’s self-confidence, self-esteem and can be downright embarrassing.

Because most people are accustomed to their own smell, it could be difficult to tell if you have bad breath without someone else’s help. Volatile sulfur compounds (VSCs) are usually the cause of bad breath, which are created when you eat and chew food, when proteins are broken down into amino acids, an important step in digestion. When these compounds are not removed from the oral cavity through proper oral hygiene (brushing and flossing after every meal), bad breath results. Most offending particulates that cause bad breath live on the back of your tongue. Your dentist can use a tool called a halimeter to measure the sulfur levels in your mouth. Bad habits such as drinking or smoking can also cause bad breath, and the offending odor usually lingers long after the cigarette or drink has been consumed. Dry mouth loosening the self-cleansing saliva can also contribute to an odorous mouth.

Most factors contributing to halitosis are self-curable, with proper diet, good oral hygiene and habitually drinking plenty of water. There are, however, a few cases in which bad breath is not self-treatable. Gum disease, cavities or problematic dental restorations trapping bacteria in the crevices around your teeth and gums can cause severe halitosis. Certain medical disorders and sinus or respiratory infections can also lead to bad breath – if you suspect you suffer from any of these maladies, see your dental professional. Although some people believe bad breath can come from the stomach, most medical professionals agree that your tummy is a very unlikely source of bad breath – unless, of course, you are belching.

You do want kissable breath, don’t you? If your bad breath is self-perpetuated, the most important thing to do is keep your oral cavity healthy. In addition to brushing and flossing after meals, be sure to clean your tongue. A tongue scraper will effectively remove all food particles from the surface of your tongue (a toothbrush can be used as well). Avoid foods that are particularly strong in smell (garlic, onions, etc…). Keep yourself hydrated with water (a moist mouth will actually smell better than a dry mouth – sweet baby breath is partly due to constant drooling!), and if you are unable to drink water, chew sugarless gum (which will promote saliva generation). Finally, always have your teeth professionally cleaned and examined twice a year. Essential oil-containing mouthwashes like Tooth and Gum Tonic can also inhibit bad breath for hours and will not dry out your mouth like alcoholic mouthwash, which you should stay away from. Stopping bad habits like drinking and smoking will also benefit your mouth greatly.
