Fissure Sealants


Your back teeth (premolars and molars) are particularly vulnerable towards developing cavities as they have lots of deep fissures that help grind up food more effectively. These fissures can be very difficult to keep clean, often trapping bacteria and food particles. It can be very difficult to get a toothbrush right into deep fissures to clean these areas thoroughly. Fissure sealants help protect these surfaces and have been proven to be very effective at helping to prevent tooth decay.

What are Fissure Sealants?

We generally recommend fissure sealants are applied to children’s newly erupted back teeth, before any cavities develop, but adults with cavity-free teeth may also benefit. Fissure sealants consist of a very thin plastic coating that is painted onto the chewing surfaces of the back teeth, effectively sealing them so decay causing bacteria cannot enter. They are a great way to help prevent cavities, and the procedure to apply them is quick and non-invasive. Dental sealants can only be used on teeth that do not have any fillings or signs of decay and will last between five and ten years before they need re-applying.

What Is the Procedure for Fissure Sealants?

If you do need fissure sealants then this treatment can be completed in one quick visit to Blue House Dental. First your teeth will be cleaned and dried before being painted with a special etching solution. This helps to slightly roughen the tooth surfaces due to be sealed, and the reason for this is to help improve the bond between the dental sealant and your tooth. The etching solution is then washed off and your teeth are dried once more. Next, your dentist will paint on the fissure sealant material, and this may be hardened with a special blue light or left to harden naturally. That’s all there is to this treatment, and you’ll be able to eat and drink normally soon after leaving our dental clinic.
