Dental Pit & Fissure Sealants Treatment & Cost

What Is It?

A sealant is a clear or tinted plastic protective coating for teeth and it is painted onto the chewing surfaces of the back teeth (molars and premolars). These are the areas where most cavities form. They protect the chewing surfaces frown tooth decay by keeping the food particles out of the grooves. Molars and premolars have grooves and crevices. Dentists call these pits and fissures. Grooves and crevices provide the perfect environment for bacteria to grow and cause cavities. Sealants help to prevent this from happening. They cover the grooves and crevices so that food cannot get into them. The first molars usually erupt when the child is 6 and second molars at the age of 12. It’s best to apply sealants as soon as they erupt to prevent decay.

Expert's Opinions

  • Dr. Reena Waghela Dental Director of Sabka dentist says "Pit & Fissure Sealants are only applied on back teeth i.e. premolars and molars since they have pits and fissures on their biting occlusal surfaces.”
  • Dr. Jena Shah Dental Director for Audit and Compliance at Sabka Dentist says "Application of Pit & Fissure Sealants is a pain free procedure and requires only a few minutes. However, they can have a lasting effect since they form a protective barrier by covering all pits and fissures, where dental decay can start early.”
  • Dr. Zita Antao Dental Director of Sabka dentist advises “An ideal age for your child to receive pit and fissure sealants is between 6 to 7 years of age. The rest are usually sealed as soon as they appear between 11 & 14 years of age.”

What It’s Used For

Sealants are applied to teeth to help prevent cavities. In the past, they usually were used only in children. But adults also can get sealants. Not only are sealants very effective, but they also cost a lot less than filling cavities. In children, sealants can be applied to baby molars to protect them from dental cavities. Eventually, these molars fall out and the new, permanent molars come in. These molars can be sealed, too. Most dentists recommend that sealants be applied to each permanent molar as soon as possible. This can be when the tooth is only partially erupted into the mouth. However, it can be done only if the tooth can be kept dry and free of saliva while the sealant is applied. If your child has a high risk of cavities, your dentist may decide to seal the premolars, or bicuspids, as well. The premolars are the teeth directly in front of the molars. Sealants can be used in adults who have an increased risk of developing cavities. Your dentist can suggest whether sealants are appropriate for you. Sealants can be put on teeth that show early signs of decay. But once the decay has broken through the enamel, the tooth will need a filling.

How It’s Done

The dentist cleans the area to remove any food or debris in and around the teeth. Then he or she makes sure the teeth are dry so that the sealant can stick. A slightly acidic solution is applied to the tooth surface to make the tooth surface rough so that the sealant can bond with the tooth surface well. The sealant is applied in liquid form. It flows over and into the grooves and crevices. The sealant usually hardens (sets) within 20 to 60 seconds. Sometimes it is set with a special light. Alternately some brands of sealants cure via a chemical process.


Studies show that sealants can last a long time, sometimes as long as 5 years. But they don’t last forever.

The dentist will check the sealants during routine visits. If necessary, the sealants can be replaced.

Remember, sealants work well, but they can’t keep teeth cavity-free without some help. Keep brushing twice a day, flossing at least once a day, and visiting a dentist regularly.

Children with sealants still should:

  • Brush twice a day with a pea-size amount of fluoride toothpaste.
  • Floss between any teeth that touch each other.
  • Get the right amount of fluoride, either by drinking fluoridated water or taking fluoride liquid or pills.
  • See a dentist regularly.


Although it is rare, sealants can cause problems in people who are allergic to plastics or components of plastics. There has also been some concern about the possible harmful effects of bisphenol A (BPA). This chemical is found in some sealants. However, studies show that any release of BPA from sealants is very small and limited to the time right after they are applied. The American Dental Association and the U.S. Food and Drug Administration have found that sealants are safe.

When To Call a Professional

Ask your dentist to talk with you about the benefits of sealants. Most pediatric dentists (dentists who specifically treat children) use sealants routinely. However, not all dentists do so. Therefore, your dentist may not think to talk with you about them.
