Dental Sealants - Cosmetic Dentistry & Dental Procedure
Information
Brushing your teeth everyday is great, but even the best oral
hygiene habits can produce wear on the teeth and produce
cavities. Dental sealants are a made of plastic materials that
are applied to the back teeth in order to prevent cavities and
nooks or crannies forming. This strong material is used to
resist bacteria and acids, as well as provide a barrier to
destructive food particles. Food and plaque are essentially
'sealed out' of the areas of your back teeth. When the sealants
are applied correctly they are nearly 100% effective in
preventing dental caries.
Sealants are usually applied at a dentist's office. Teeth are
first cleaned and dried before a thin layer of plastic liquid is
painted over the nooks and crannies of the back teeth. After the
plastic liquid is applied a blue spectrum light is shined on the
material to force the plastic to cure. If a blue spectrum light
is not used it is probably because a different brand of sealant
is being used. Some brands of sealants cure chemically.
After the sealants have hardened it turns into a thin layer of
plastic covering the back teeth. Generally sealants can last up
to five years or longer, although they should be checked
periodically for damage. If sealants become damaged they can
easily be replaced simply by adding new sealant material to the
worn areas.
