Fissure Sealants

Our teeth are constantly being covered with a sticky film of bacteria called plaque.

When we eat or drink anything that contains sugar – such as cookies, lollies, soft drink, juice, fruit, milk and many other foods and beverages – bacteria turn the sugar into acids that can attack tooth enamel.

Tooth decay often occurs on the chewing surfaces of the back teeth. These surfaces have pits and grooves (fissures) that trap plaque, bacteria and bits of food.

The pits and fissures are hard to keep clean, because toothbrush bristles cannot reach into them. That is how decay starts in the grooves and a cavity forms.
