ProtectYourEnamelFromtheDamagingEffectsofAcid

One of your teeth's best defenses against tooth decay is its hard, outer layer made of a mineral-rich substance known as enamel. This great protector, however, has an enemy — acid — from the foods and drinks we consume as well as the acid byproducts from bacterial plaque. A high acidic level in the mouth could lead to the complete erosion of enamel, leaving teeth more susceptible to decay.

When the acid level in the mouth rises, calcium and other minerals in enamel become soft and begin to slough off, a process called de-mineralization. But the body can reverse this process with the help of saliva, which can neutralize acid. Saliva also contains calcium that can bind to the tooth surface and help replace what was lost during de-mineralization — a process known as re-mineralization. Saliva can normally accomplish this in thirty minutes to an hour after eating.

Unfortunately, saliva's neutralizing power can be overwhelmed when there is too much acid present. This occurs when we ingest substances like sodas or sports drinks that are high in citric acid. Many of these same beverages also have a high buffering capacity that slows the neutralizing effect of saliva. Ironically, we can also interrupt re-mineralization if we brush our teeth too quickly after eating or drinking something acidic. The enamel has been softened by the acid and when we brush before re-mineralization we can actually brush away some of the enamel.

There are some steps you can take to help this natural process for maintaining a healthy pH balance in the mouth. First, limit your intake of acidic foods and beverages. Drink water for rehydration, or at least acidic beverages enriched with calcium. If you do drink an acidic beverage use a straw to reduce acid contact with teeth, try not to swish it around in your mouth, and try to drink it during mealtime. Finally, wait 30 to 60 minutes before brushing your teeth after eating or drinking something acidic.

Tooth enamel is a key component in maintaining healthy teeth. Protecting this prime defense against decay will pay you dividends for many years to come.

Nolan Gould, who plays Luke on the popular TV comedy Modern Family, has beautiful, straight teeth. But in an exclusive interview with Dear Doctor magazine, the young actor said it wasn't always that way.

“My teeth used to be pretty messed up,” Nolan said. “I had two extra teeth when I was born. They hadn't come out (erupted) yet. And all the other teeth that were already there were starting to point backwards because it was getting so crowded in my mouth. At about the age of 7, I started going to the orthodontist to get my teeth checked.”

Age 7 may sound early for a visit to the orthodontist, but in fact that's exactly the age we recommend for a first orthodontic evaluation. Malocclusions (bad bites) often become noticeable around this time, as the child's permanent (adult) teeth erupt. We might already be able to see evidence of the following problems: crowding, too much space between teeth, protruding teeth, extra or missing teeth, and sometimes problems with jaw growth. So even if your child is too young for braces, it is not necessarily too early for an orthodontic evaluation.

This type of exam can spot subtle problems with jaw growth and emerging teeth while some baby teeth are still present. Early detection of orthodontic problems makes it easier to correct those problems in the long run. Waiting until all of the permanent teeth are in, or until facial growth is nearly complete, may make correction more difficult or even impossible. That's why the American Association of Orthodontists recommends that all children get a check-up with an orthodontist no later than age 7.

Orthodontic treatment itself usually begins between ages 7 and 14. Therapy that begins while a child is still growing, often referred to as “interceptive orthodontics,” helps produce optimal results. In Nolan's case, an early orthodontic evaluation allowed his orthodontist enough time to plan the most effective treatment. Nolan's two extra teeth were removed before they had a chance to push his other teeth even further out of alignment, and he was given orthodontic appliances which fit behind the teeth.

“You can remove them, which is really good for acting, especially because you can't see them. I can wear them 24/7 and nobody will ever notice.”

One thing that is noticeable, however, is Nolan's perfectly aligned smile!
