Do you all know that most of the children will develop cavities by the time they reach kindergarten? Poor hygiene result in severe tooth decay in baby teeth and genetics may also contribute sometimes.

It is important to protect the teeth from decay to let your child stay healthy and strong for a lifetime. One way is to apply dental sealants to the permanent molars of a child which lower risk for tooth decay.

Dental sealants are a plastic coating which is placed on the chewing surface of the permanent back teeth – the molars and premolars. This protects them from decay.

Dental sealant is placed on teeth for protection

The chewing surfaces of molars and premolars teeth have grooves which make them vulnerable to decay. These can be deep, narrow and difficult to clean with a single bristle of a toothbrush.

A bacterium accumulates and attacks the enamel which leads to the development of cavities. However, fluoride helps prevent decay and protects the surfaces of the teeth. Dental sealants ensure extra protection for the grooved and provide a smooth surface.

Placing of dental sealants

The molars and premolars continue to erupt until the age of 11-13 years. The dental sealant is placed on the groove of the permanent molar teeth which protects the tooth if they have completely erupted. Dentists-

  • Clean the tooth surface with a paste and rotating brush
  • Wash with water and leave it for dry
  • The acidic solution is applied before rinse

This all creates small microscopic areas and a fine rough surface surrounding tooth enamel. With the help of dental sealant, it can be attached to the tooth. Once the tooth is dried again, the liquid dental sealant is placed and hardened. The dental sealants once get hardened becomes a hard plastic and let you chew again.

Dental sealants are effective that helps in preventing decay on chewing surfaces. It lasts for many years and if required, a new dental sealant can also be placed on the tooth.
