Tooth decay is not trivial. It's a worldwide epidemic, one of the most common of all diseases — second only to the common cold. It affects more than one fourth of U.S. children of ages 2 to 5 and half of those 12 to 15. Among adults, tooth decay affects more than ninety percent of those over age 40.

Prevention of cavities starts with a healthy diet and effective brushing and flossing, but it is much more complex than that. Three strategies for reducing dental caries (tooth decay) include:

Protect with Fluoride and Sealants
This works best when fluoride is applied to the crystalline coating of your child's teeth just after they push through the gums (erupt). The fluoride becomes incorporated into the tooth's surface and acts as a barrier to decay. Studies have shown that low doses of fluoride are safe and effective.

Dental sealants are used as a companion to fluoride because they seal tiny pits and fissures in the tooth's structure, creating an even stronger barrier.

Modify Oral Bacteria
Every mouth contains bacteria, no matter how well you clean your teeth. Not all bacteria cause tooth decay. The problem bacteria are those that produce acid as a byproduct of their life processes. We can identify acid-producing bacteria in your mouth, you can reduce their concentrations using antibacterial mouthrinses such as chlorhexidine, and pH neutralizing agents (substances that reduce the amount of acid).

Reduce Sugars in Your Diet
Bacteria in your mouth ferment sugars and other carbohydrates, producing acids that eat into the mineralized outside structure of your teeth, the enamel. So eating fewer sugars — particularly added sugars such as those in juices, sodas, candy and other sweets — will help prevent decay. Your total sugar intake should be less than fifty grams, or about ten teaspoons, per day. If you begin to read labels showing sugar content of common foods, you may be surprised at the amount you consume without knowing it.

If you must snack between meals, non-sugary snacks like raw vegetables and fresh fruits create a better environment for your teeth.

Xylitol, an “alcohol sugar” used in some chewing gums and dental products, has been shown to reduce decay-producing bacteria.

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.”

If you like soft drinks and carbonated colas, beware. Acids in these drinks may be dissolving the minerals in your teeth — a process called chemical erosion. And don't think that natural fruit juices or sports and high energy drinks are any better than sodas. They also contain acids that dissolve the surface enamel of your teeth. Once your enamel is lost, it is gone forever. It cannot naturally recover.

Sadly, teeth in children and teenagers — an age group most likely to drink large quantities of soda and juices — may be more easily eroded by acids. These youngsters have not had long-term exposure to fluorides which harden tooth enamel and protects them from acid erosion.

The Difference between Erosion and Decay
Chemical erosion is not the same as tooth decay (cavities). In chemical erosion, acids in your mouth react directly with minerals in the outer enamel of your teeth. In the case of tooth decay, bacteria in dental plaque (a bacterial film that forms on your teeth) utilize the sugars in the drinks and produce acids that attack your teeth.

After Acidic Exposure, Wait 30 Minutes to an Hour before Brushing
You may think that the solution to chemical erosion is to brush the acidic solution from your teeth as soon after drinking them as possible. But tooth brushing immediately after can actually accelerate chemical erosion and make it worse. After they are bathed in an acidic solution, minerals in the tooth surface become partially dissolved. Brushing at this time may brush away the affected layer. If you wait a half hour to an hour, your saliva will have time to neutralize the acids and harden the tooth surface by adding minerals back into it.

Drinks Less Likely to Cause Dental Erosion
Instead of drinking colas and sports drinks, stick to water and/or milk, which have the added benefit of supplying calcium to help add minerals back to the tooth surface.

If you must sip on juices or soft drinks, try to do so only at mealtimes. This is preferable to drinking them all day long, which leaves your teeth constantly bathed in an acid solution. Avoid swishing the drinks in your mouth, and sip them with a straw to reduce contact between acidic drinks and your teeth.

While some people associate the need for root canal treatment with an injury or trauma to a tooth (which is a valid cause), it can also most commonly be caused by tooth decay that is left untreated. This is the reason why we have put together this brief guide to explain the three common stages of tooth decay that lead up to the need for a root canal.

Stage 1: During this stage, decay begins to form in the tiny grooves on the biting surface of a tooth or where the teeth contact each other. The result is loss of the surface enamel of the tooth.

Stage 2: Left untreated, the disease progresses through the enamel and into the dentin, which forms the body of the tooth. Once in the dentin, it progresses more rapidly until it reaches the pulp — the living tissue within the root canals of the tooth. The decay infects the pulp tissues, which contain the nerves of the teeth, causing pain. The end result of inflammation and infection of the pulp is that it dies.

Stage 3: As the nerve dies an infection results, which causes pain and swelling. For some people who do not regularly visit our office, this may be the first physical sign that they have a problem. But all is not lost, a successful root canal treatment, whereby the infected pulpal tissue is removed and the root canals are cleaned and sealed will not only relieve the pain, but save your tooth. So the good news is that once a tooth has had the appropriate endodontic treatment (“endo” – inside; “dont” – tooth) followed by a proper restoration, the tooth can last as long as your other teeth. The key is to take proper care of your teeth, have routine cleanings, and visit our office as soon as you feel you have a problem with a tooth.

If you are having pain or symptoms from a tooth or teeth, check it out with us — you may or may not need a root canal treatment. Contact our office to schedule an appointment and find out. Don't wait until it's too late. And to learn more about the signs, symptoms, and treatments for a root canal, read the article “I'd Rather Have A Root Canal....”
