What are fissure sealants?

A fissure sealant is a material that essentially covers the grooves of teeth. Protecting deep grooves reduces the chance of tooth decay on the top of your teeth. These grooves are known as "pits" and "fissures". A pit is a small depression on the surface of the tooth, whereas fissures are the grooves that naturally occur on all biting surfaces of teeth. Most of the time, the teeth at the back (the premolars and molars) have the most grooves, however the teeth at the front (incisors and canines) can also have pits and fissures.  These pit and fissures can be deep or shallow.

Pits and fissures on the surface of the tooth are ideal in harbouring dental plaque and calculus, which containbacteria. This area of plaque and calculus is often very difficult to clean, as the bristles on your toothbrush are often not able to get to the deepest part of these grooves. If the groves are not cleaned properly, decay will start on the top of the tooth, and the tooth will sometimes need a filling.

Fluoride, in your toothpaste and in your water, is very effective in protecting against decay; however its effect is minimal on the biting surface of teeth. Much of the decay encountered by school-aged children occurs in these pits and fissures, thus it is important to have a preventive agent to protect against decay. An American survey showed that up to 84% of the decay encountered in school-aged children is in these pits and fissures.

Why are sealants used?

Pit and fissure sealants were designed specifically for three preventive effects:

  1. Sealants occupy the pits and fissures of teeth with a resin material;
  2. As the pits and fissures are filled up, bacteria are not able to go deep into grooves, and this causes less "bad' bacteria to be present on the tooth; teeth with fissure sealants are 22 times less likely to develop decay than those that have not been filled; and
  3. Sealants render the pits and fissures easier to clean during brushing and chewing, as food particles do not get trapped as easily when you have deep fissures.

Note that the picture on the left has clearly visible pits and grooves on the surface of the tooth. The picture on the right depicts a white sealant that has been placed to fill in the grooves.

Types of fissure sealants

The choice is one of personal preference. However, it has been demonstrated that coloured sealants (those that are very white or even pink) are more obvious to the person who has the sealant and dentist examining the sealant. The more obvious fissure sealants are, the easier it is to see whether they need replacement.

The amount of the time the sealant usually lasts depends on how well the contamination (from saliva, blood, and water) is controlled by the dentist during the procedure. Sometimes a rubber dam, or several pieces of cotton wool will be required to dry the area completely.

Glass ionomer cements, which are slightly different to the plastic sealants, usually do not last as long. They are useful for those children who are at high risk of dental decay, or when it is technically demanding to place the sealant; e.g. teeth that are still mostly in the gums or those children showing poor cooperation at the dentist.

How much do fissure sealants get used?

It is clear that sealants are safe, effective and underused. Approximately 20% of children aged 5-17 have fissure sealants on their baby or adult teeth. It is often said by dentists and reseachers that if the amount of fissure sealants was higher, the amount of decay would be lower.


How effective are fissure sealants?

Dental healthIt is clear that fissure sealants are extremely good in reducing the chance of future decay. Several studies over 30 years have shown this, however many studies have also shown that sealants are also prone to falling out. On average, one half of the sealants remain for 7 years, 30% require one reapplication, 10% require two reapplications, and 10% required more than three applications.

If sealants are lost, it is most likely a result of technical error in the sealant's application rather than the result of poor bond strength. If applied properly, the bond between sealant and tooth is unlikely to fail. Most sealants that fail occur in the first 6 months, and this most likely comes down to the fact there was contamination during the placement of the fissure sealant.

Decay is at times very hard to diagnose on a person's tooth, thus some dentists are worried that placing a sealant over decay will cause further decay in the future. Even if a small amount of decay is covered by the dentist accidentally, these areas of decay do not progress rapidly, if at all. Some dentists even intentionally leave a small amount of decay in place, to avoid further damage of the tooth, and this is also acceptable.

From a cost-effectiveness point of view, it has been concluded that sealants are justified in a person who is at risk of decay in their mouth, that is, those individuals with 2 or more decayed, missing, or filled teeth due to decay. Conversely, if a person was not at a high risk, it was recommended to avoid placing sealants from a cost point of view.

The total average time to place sealants is around 10 minutes, while the average time to place a similar amalgam filling (silver filling) is about 14 minutes.

Sealants can therefore be concluded:

  • To be effective in preventing decay;
  • To have a reasonably long term retention in the mouth;
  • To stop decay that has been covered by the dentist; and
  • To be better to amalgam in terms of time requirements, and tooth destruction.

When should sealants be used?

Below is a generalised overview of whether a dental professional should use a fissure sealant.



Do not seal

Tooth age

A tooth that has just come through into the mouth.

Teeth that have remained free of decay for 4 years or longer.

Tooth type

Molars (which are the teeth at the back of your mouth)

Front teeth (very rarely is there a need to seal front teeth)

Depth of pits and fissures

Deep, retentive, narrow pits and fissures, which are excellent at attracting plaque

Wide, unretentive, shallow grooves that are easily cleaned by the person

The risk of decay

Teeth that are soft, or in a person who has had decay in two or more teeth

Teeth that have remained free of decay for 4 years or longer

Availability of other preventive measures

Person is having fluoride in their diet and still has decay

Person is not following dentist's advice, and is continually getting more decay; this will require a filling rather than a sealant

Procedure for placing sealants

Fissure sealant application is a relatively straightforward procedure that can be completed by a dentist, dental therapist, or dental hygienist.

The general procedure is:

  1. Teeth are thoroughly cleaned and dried, as food debris and saliva can prevent the sealant from sticking correctly to the tooth.
  2. The tooth surface is coated with a weak acid gel or chemical solution, to ensure that the sealant bonds to the tooth.
  3. An adhesive is applied under the sealant.
  4. The sealant is applied.
  5. Depending on the type of sealant, a strong light may be used to activate bonding and hardening of the material.
  6. The liquid sealant forms a durable material on the tooth surface.
  7. The bite is checked, and excess material is polished off.

Maintenance of fissure sealants

Dental healthDentists usually recommend 6-12 monthly check-ups so that tooth decay or sealant loss can be monitored.

Sealed teeth generally do not require any changes at home, or dietary changes. Although fissure sealants help with decay prevention on molar teeth especially, it is important to regularly brush and floss teeth and avoid the factors that can lead to tooth decay.
