Conceal Those Holes To Maintain Beautiful Teeth

 What are dental sealants?

Dental sealants are plastic coatings that are usually placed on the chewing (occlusal) surface of the permanent back teeth, molars and premolars to help protect them from decay.

 

 Which teeth are suitable for sealants?

Permanent molars are the most likely to benefit from sealants. The first molars usually come into the mouth when a child is about 6 years old. Second molars appear at about age 12. It is best if the sealant is applied soon after the teeth have erupted, before they have a chance to decay.

Sealants are easy for your dentist to apply. The sealant is painted onto the tooth enamel, where it bonds directly to the tooth and hardens. This plastic resin bonds into the depressions and grooves (pits and fissures) of the chewing surfaces of back teeth. The sealant acts as a barrier, protecting enamel from plaque and acids. As long as the sealant remains intact, the tooth surface will be protected from decay. Sealants hold up well under the force of normal chewing and may last several years before a reapplication is needed. During your regular dental visits, your dentist will check the condition of the sealants and reapply them when necessary.

 

Why are dental sealants placed on teeth?

The chewing surfaces of the molar and premolar teeth have grooves “fissures” that make them vulnerable to decay. These fissures can be deep, are difficult to clean, and can be narrower than even a single bristle of a toothbrush. Plaque accumulates in these areas, and the acid from bacteria in the plaque attacks the enamel and cavities can develop. Fluoride helps prevent decay and helps protect all the surfaces of the teeth, dental sealants provide extra protection for the grooved and pitted areas by providing a smooth surface covering over the fissured area.
Key ingredients in preventing tooth decay and maintaining a healthy mouth are:

  • brushing twice a day with an ADA-accepted fluoride toothpaste
  • cleaning between the teeth daily with floss or another inter-dental cleaner
  • eating a balanced diet and limiting snacks
  • visiting your dentist regularly

How are sealants applied?

Applying sealants does not require drilling or removing tooth structure. The process is short and easy. After the tooth is cleaned, a special gel is placed on the chewing surface for a few seconds. The tooth is then washed off and dried. Then, the sealant is painted on the tooth. The dentist or dental hygienist also may shine a light on the tooth to help harden the sealant. It takes about a minute for the sealant to form a protective shield.
