Pit and Fissure Sealants

Tooth decay is one of the most common oral problems, and a prime location for tooth decay to occur is in the pits and fissures of your teeth.

Pits and Fissures.

• Pits and fissures are the deep grooves that make up the chewing surfaces of your teeth. These grooves are found on both your premolars and molars.
• Although pits and fissures help you to chew, food can still get stuck in these grooves. Plaque, a bacterial film that forms on your teeth, can also accumulate here if not cleaned regularly. It’s hard to reach these areas with your toothbrush, so food and plaque can remain in place and lead to cavity formation.
• The bacteria in your plaque feed on sugars from foods and drinks, and when it does, it produces acids that attack your protective tooth enamel. Over time, your enamel wears down and allows tooth decay to set in.
• Your dentist can help you prevent pit and fissure cavities by curbing the initial decay. Alongside basic scalings, he or she may apply protective material known as a dental sealant to your premolars and molars. A dental sealant is a white or clear plastic coating that fills in your pits and fissures and prevents plaque and food from getting inside. This product is usually applied to children’s teeth as soon as their permanent teeth erupt – between the ages of six and 12 – but it can also be applied to adult teeth if your dentist determines that you need it.
• if your pit and fissure cavity is deeper and reaches the dentin, it will need to be repaired with a filling, or in some cases, a crown. Fillings are used for areas of smaller and medium decay, whereas crowns are used to repair larger tooth decay that compromises the structure of the tooth itself.
