Dental sealants are barriers that can protect one's teeth from developing cavities. Made out of plastic material, there are usually applied to the molars and premolars at the back of the mouth.

How are dental sealants applied?

• The teeth on which the sealant is to be applied is cleaned properly and then dried. A solution containing acid is applied on the teeth to make the surface rough, as this helps the sealant bond well with the teeth.
• Then the teeth are rinsed, following which they are dried. Finally, the sealant is applied. At times, a special light is used to make the sealant dry easily.

Reasons to use dental sealants:

• The chewing surfaces of the teeth are aided by dental sealants. Sealants are thin coatings that are painted on those areas.
• One main reason for using sealants would be that even though brushing and flossing can remove the food particles stuck in the grooves of the teeth, at times some particles may be left behind. Sealants can prevent this.
• The sealant spreads over the enamel in the grooves of the teeth, acting as a shield. This prevents food particles from getting stuck in the pits and fissures of the teeth. When such food particles are stuck in the grooves of the teeth, cavities are likely to form. Applying sealants can prevent this.
• Children, who are at a greater risk of developing cavities, are often advised to use dental sealants to prevent their teeth from decay and damage.
• Adults whose teeth have suffered considerable decay may seek the help of sealants to protect them.
• Adults who have had fillings done in their teeth cavities may also apply sealants in order to prevent any further damage in the near or distant future.
