The shape of many teeth makes it impossible to completely eliminate all food particles and sugars from within the deep grooves and pits found on the chewing surfaces, especially in the back teeth.

These areas are usually the first to decay during or even before the early teenage years. Today, these decay-prone areas can be protected early in life by the application of a thin layer of resin which is bonded into the crevices and pits found in the enamel layer. This coating, known as fissure sealants, creates a very effective barrier between oral bacteria and the deeper layers of the tooth.

What is plaque and why does it cause cavities?

After eating and drinking, bacteria colonise the surface of teeth in a sticky film called plaque that attaches on and in between tooth surfaces. Plaque often is found on the chewing surfaces of the back teeth, from which it is difficult to remove by brushing and flossing alone. If plaque is not removed regularly from teeth, acids which are produced by these bacteria will dissolve the protective layers, the enamel and dentine, creating holes (cavities) which allow more and more bacteria to proliferate. This results in more rapid decay, which leads to the destruction of the inner layers of teeth and toothaches, infections, facial swellings etc.

Is it difficult to apply sealants?

No. It is a completely painless treatment that lasts for many years.

Who should get sealants?

Sealants are most effective in reducing cavities in children with newly formed permanent teeth but are also useful in preventing the formation of decay in adult teeth. It is an effective way to reduce the need for fillings and more expensive treatment that may be required to repair the damage from large cavities.
