FLUORIDE

Fluoride helps prevent tooth decay by making the tooth more resistant to acid attacks from plaque bacteria and sugars in the mouth. It also reverses early decay. In children under six years of age, fluoride becomes incorporated into the development of permanent teeth, making it difficult for acids to demineralize the teeth. Fluoride also helps speed remineralization as well as disrupts acid production in already erupted teeth of both children and adults.

In What Form is Fluoride Available?

Dentists in his or her office can also apply fluoride to the teeth as a gel, foam, or varnish. These treatments contain a much higher level of fluoride than the amount found in toothpastes and mouth rinses. Varnishes are painted on the teeth; foams are put into a mouth guard, which is applied to the teeth for 1 to 4 minutes; gels can be painted on or applied via a mouth guard.

When Is Fluoride Intake Most Critical?

It is certainly important for infants and children between the ages of 6 months and 16 years to be exposed to fluoride. This is the timeframe during which the primary and permanent teeth come in. However, adults benefit from fluoride too. New research indicates that topical fluoride — from toothpastes, mouth rinses, and fluoride treatments — are as important in fighting tooth decay as in strengthening developing teeth.
In addition, people with certain conditions may be at increased risk of tooth decay and would therefore benefit from additional fluoride treatment. They include people with:

1. Dry mouth conditions : Dry mouth caused by diseases such as Sjцgren’s syndrome, certain medications (such as allergy medications, antihistamines, anti- anxiety drugs, and high blood pressure drugs), and head and neck radiation treatment makes an individual more prone to tooth decay. The lack of saliva makes it harder for food particles to be washed away and acids to be neutralized.
2. Gum disease : Also called gingivitis, gum disease can expose more of your tooth and tooth roots to bacteria increasing the chance of tooth decay.
3. History of frequent cavities : If you have one cavity every year or every other year, you might benefit from additional fluoride.
4. Presence of crowns and/or bridges or braces. These treatments can put teeth at risk for decay at the point where the crown meets the underlying tooth structure or around the brackets of orthodontic appliances.
