How Dental Sealants Stop Tooth Decay

At times your dentist can place a plastic coat on the chewing (occlusal) surface of the permanent back teeth (the molars and premolars).

Food particles get deposited in the narrow grooves and it can be tricky to wash them as the fissures may be thinner and deep than even just one bristle of a toothbrush. Plaque (a sticky substance that is formed when bacteria present in the mouth get deposited alongside saliva, food particles and other organic substances on the surface of their teeth) gets collected in them. The bacteria in plaque split the sugar (carbohydrate) in meals and lead to the formation of acid in the mouth and may lead to tooth decay if it’s not removed.

When are dental sealants applied?

In children, a dentist may employ sealant the moment the molar teeth come completely into the mouth (perceptible) to shield them from caries. Application of dental sealant onto the chewing (occlusal) surfaces of these teeth helps to protect the enamel from caries.

Can dental sealants be utilized only on the chewing surface of molar and pre molar permanent teeth?

Dental sealants are mostly used to cover the chewing gum (occlusal) surfaces of the back permanent teeth (the molars and premolars) as they have pits or grooves. The sealant will help to protect the teeth from decay. They may be put on other teeth if they have grooves or pits.

Can dental sealants be used on teeth of adults?

Yes, sealants can be placed on teeth of adults also. But they’re used less frequently in adults. They are used in adults if they have heavy grooves and fissures which don’t already have fillings or even dental sealants.

What do dental sealants look like?

Various forms of sealant exist. They may be clear, white or have a slight tint depending on the sort of dental sealant that’s used.

Your dentist will first wash your teeth with a brush and paste, then rinse and dry your tooth/teeth. An acidic solution is going to be put on the tooth to make a fine rougher surface than the surrounding tooth enamel (this rough surface promotes the dental sealant to attach to the tooth). After drying the tooth that your dentist will put the liquid dental sealant on the tooth and it is hardened by using a light. After the sealant pops on the tooth you may chew on the tooth again.

How long can one dental sealant last?

Dental sealants are demonstrated to be effective in preventing corrosion on gum (occlusal) surfaces. They can last for decades and can be reapplied if necessary.

Is fluoride needed following dental sealant is put?

Yes, as the sealants protect just the surface they are applied on where as fluoride protects all the surfaces of the tooth from decay and cavities.
