Fluorides
We can receive fluorides in two general ways:
-
Systemic fluorides
-
Topical fluorides
Systemic fluorides include the fluoride in water that we drink. If fluoride
is ingested during the years when teeth are developing ( birth to about
the age of 12 years), it is incorporated into the actual structure of the
enamel. This provides a very acid-resistant structure that is less likely
to decay than tooth enamel without fluoride. In areas where
the water is not fluoridated, we can prescribe fluoride tablets or drops
to administer to your children.
Fluoride
accomplishes it decay-resistant properties by "neutralizing" the acid that
causes decay. The drawing to the right shows "blue" unprotected enamel
being "decayed" by the "green" acid. The top area of the drawing is an
actual electron microscopic photo of non-fluoridated enamel.
This
drawing depicts fluoridated enamel as a darker blue. As the fluoride neutralizes
the acid, the fluoride is "used up". It is then important to replenish
the fluorides with topical fluorides. Also, note the denser enamel in the
electron microscope photograph.
The topical fluorides include:
-
Acidulated fluoride treatments at our office
-
Fluorides in toothpaste and some mouthrinses
such as "Act" and "Listermint"
-
Prescription fluoride gels
-
Fluoridated drinking water
