A number of factors can lead to dental caries (tooth decay). To find out if you are at high risk, ask yourself these questions.

Is plaque visible in my mouth?
Dental plaque is a whitish film of bacteria that collects on your teeth. If it is clearly visible, it means that there is a lot of it. Among the bacteria in the plaque are those that produce tooth decay, particularly in an acidic environment. (A normal mouth is neutral, measured on the pH scale, midway between the extreme acidic and basic ends of the scale.)

Do I have a dry mouth?
Saliva protects your teeth against decay by neutralizing an acidic environment and adding minerals back to the outer surface of enamel of your teeth, so reduced saliva is a high risk for caries. Many medications can cause dry mouth as a side effect.

Do I eat a lot of snacks, particularly unhealthy ones?
Frequently eating sugars, refined carbohydrates, and acidic foods promotes the growth of decay-producing bacteria. The more frequently you eat, the longer your teeth are bathed in sugars and acids. Acidic foods not only promote bacterial growth, they also directly cause erosion of the tooth's hard surface by softening and dissolving the minerals in the enamel.

Do I wear retainers, orthodontic appliances, bite guards or night guards?
These appliances are recommended for various conditions, but they tend to restrict the flow of saliva over your teeth, cutting down on the benefits of saliva mentioned above.

Do my teeth have deep pits and fissures?
The shape of your teeth is determined by your heredity. If your teeth grew in with deep grooves (fissures) and pits in them, you are at higher risk for bacterial growth and resulting decay.

Do I have conditions that expose my teeth to acids?
If you have bulimia (a psychological condition in which individuals induce vomiting), or GERD (Gastro-Esophageal Reflux Disease), your teeth may be frequently exposed to stomach acids that can cause severe erosion to your teeth.

Do I already have cavities?
Visible cavities can range from those only visible with laser technology or x-ray examination to those a dentist can see with a naked eye. If you already have small cavities, you are at high risk for developing more.

Do I have white spots on my teeth?
White spots are often the first sign of decay in a tooth's enamel. At this point, the condition is often reversible with fluorides.

Have I had a cavity within the last three years?
Recent cavities point to a high risk of more cavities in the future, unless conditions in your mouth have significantly changed.

If you have any of these indications of high risk, contact us today and ask us for suggestions for changing the conditions in your mouth. You can also learn more by reading the Dear Doctor magazine article “Tooth Decay.”

1. Xylitol is a kind of sugar.
   True or False
2. Xylitol is made from
   1. Bark of birch trees
   2. Coconut shells
   3. Cottonseed hulls
   4. All of the above
3. Xylitol is a natural “sugar alcohol” similar to other so-called sugar alcohols such as mannitol and sorbitol.
   True or False
4. Xylitol is broken down by decay-causing bacteria to produce acid.
   True or False
5. Decay-causing bacteria are transmitted from a parent to a child through oral contact such as a simple lip-to-lip goodnight kiss.
   True or False
6. Researchers have found no difference in prevention of tooth decay in gum made from xylitol compared to gums containing sorbitol/xylitol and sucrose.
   True or False
7. Other xylitol products such as mints, candy and cookies also seem to decrease the incidence of tooth decay.
   True or False
8. Xylitol products increase salivary flow and allow saliva to neutralize acids in your mouth.
   True or False
9. The only side effect of too much xylitol ingestion is a possible mild laxative effect.
   True or False
10. The target dose of xylitol is one to two teaspoons spread throughout the day.
    True or False

1. True. Xylitol is a kind of sugar that does not contribute to tooth decay.
2. All of the above. It is also found naturally in some fruits and vegetables.
3. True. The others, mannitol and sorbitol, are used as sugarless sweeteners.
4. False. Unlike sucrose (table sugar), xylitol is NOT broken down by bacteria to produce acid. Xylitol also stops saliva from becoming acidic so your mouth becomes an unfriendly environment to acid-producing bacteria.
5. True. However, xylitol inhibits growth and attachment of the bacteria to your teeth, so it also inhibits transmission to your children.
6. False. Systematic use of xylitol chewing gum significantly reduces the relative risk of caries (tooth decay) when compared to chewing gums containing sorbitol/xylitol and sucrose. Xylitol gum also appears to halt the development of tiny cavities when compared to other types of chewing gum.
7. True. Use of these products seems to stop the progression of active decay.
8. True. Xylitol and your saliva combine to re-mineralize (harden) your teeth after an acid attack.
9. True.
10. True. This means two pieces of xylitol gum or two pieces of xylitol candy or mints should be consumed for five minutes four times a day after eating meals or snacks.

Dental caries (tooth decay) is similar to the pesky bumblebee that invades your lovely summer barbecue. You can find temporary solace from this intruder by eliminating that very first bee that you see, but if you are situated in an area that is close to the bee's nest, it won't be long before the next bee buzzes along. This is similar to tooth decay. Having one cavity-laden tooth drilled and filled is really just a temporary fix. The underlying conditions that led to tooth decay in the first place need to be addressed in order for your risk of future infection to decrease.

Researcher Dr. John Featherstone created the concept of the Caries Balance in 2002, in which he explained that tooth decay and overall dental health are dependent upon a proper balance of disease-causing and health-promoting factors. Discovering what the fundamental problem really is (and getting as far away from that hornet's nest as possible) can help both determine and curb your risk for future tooth decay.

Here's the issue in a nutshell: Susceptible teeth, in the presence of acid producing bacteria when fed by sugar from your diet, basically, will create all the conditions necessary to cause tooth decay.

To determine your risk for tooth decay, see how many times you answer “Yes” to the following questions:

1. Do you brush your teeth twice a day to reduce bacterial plaque sticking to the teeth?
2. Do you use fluoride toothpaste to strengthen the teeth against acid attack?
3. Do you use a fluoride mouthrinse?
4. Do you floss daily?

Every affirmative answer decreases your risk of getting cavities, but even doing all of this may not be enough!

Now, how many times can you answer “Yes” to these questions?:

1. Do you smoke? Smoking causes mouth dryness, and creates a host of other health problems.
2. Do you snack frequently between meals? One sugary snack and your mouth is acidic for the next hour. One snack per hour and your mouth is acidic all day.
3. Do you frequently have acid reflux or heartburn? Reflux creates extreme acidity in the mouth and directly erodes tooth enamel.
4. Do you drink soda, sports drinks, or acidic beverages frequently? These beverages are very acidic.
5. Is your mouth frequently dry? Do you take any medications that cause mouth dryness? Saliva is nature's own defense against acidity and helps neutralize acid in the mouth.
6. Have you had frequent cavities in the past and/or have you had any crowns or fillings in the past three months? The best indicator of future disease is past disease!

Every affirmative answer increases your risk of getting cavities!

Now that you are a little more knowledgeable about your personal risk for tooth decay, make an appointment with us to discuss the preventative measures that can give you some control over the future condition of your teeth. Ignoring the risks and then ending up with a mouth full of rotting teeth when you knew better could really sting a little!

Given the fact that baby-boomers are now reaching the age of retirement, understanding senior healthcare is becoming a top priority to many people. Discover your level of expertise in the area of oral health by taking the following true/false test.

True or False Self Assessment

1. All people eventually lose their teeth as they age.
2. Yellow teeth are a sign of gum disease.
3. If you have dentures, you no longer need regular dental check-ups.
4. Periodontal (gum) disease is a big problem that affects 3 out of 4 adults.
5. Electric toothbrushes can be a great option for seniors with arthritis or other debilitating conditions.

Answers

1. False: Your teeth are meant to last your lifetime.
2. False: Yellow teeth typically denote stained teeth from diet, medication, smoking, or growing older. And while they may not appear attractive, older, yellow teeth can in fact be healthy and free of gum disease. However, if your yellow teeth bother you, ask us if teeth whitening could be right for freshening up your smile while making you appear younger.
3. False: For those individuals who wear complete upper and lower dentures, you will always need routine dental exams, typically once a year so that you can be screened for cancer, as well as other oral conditions (i.e. candadiasis), to ensure the you obtain and maintain optimal oral health.
4. True: 75% of all adults over the age of 35 will experience some form of periodontal disease, a condition in which the gums become inflamed and infected. If left untreated, gum disease causes the bone that supports the teeth to deteriorate until the teeth are loosened and/or eventually lost (either they fall out on their own or must be removed). On a positive note, you can prevent gum disease by having good oral hygiene that includes flossing daily and brushing at least twice a day with a proper technique and fluoride toothpaste.
5. True: Under normal conditions, what matters most is not so much the type of toothbrush used (manual, electric or battery powered toothbrush), but rather how you use it. However, if you are unable to use a manual toothbrush effectively for proper brushing, then a power toothbrush may be able to facilitate proper cleaning more easily.
