Molar Sealants

Dental Burwood  – Back Molar problems

Our back molar teeth are different to our front teeth. The front teeth are optimised to bite off food. Our back teeth are optimised to then chew this food. The rough upper surface of the molar helps this chewing action, but unfortunately, this same rough surface is prone to retaining food debris, leading to decay.

The rough upper surface of the molar teeth may have larger and smaller grooves and spaces. The larger grooves help with the chewing of food. The smaller surfaces do not really help in any way and are prone to holding very tiny food particles, and plaque. It can be difficult to clean these small spaces as some are smaller than the bristles of the toothbrush. So over time, the food particles stuck in these molar teeth can lead to decay.

Molar Sealants – Dental Burwood

For the past two generations dentists have been applying a sealant to the top of molar teeth. This greatly reduces decay in the molar teeth, at least decay in the top of the teeth.

Dental sealants fill in the tiny spaces on the molar surface while leaving the larger grooves unaffected. This means the molar teeth can still chew quite well but are far less likely to retain food debris or plaque, at least on the top of the teeth. When a sealant is on the tooth surface it is reasonably easy to keep the teeth clean with a thorough brushing.

Sealants History – Dental Burwood

Sealants are either white-coloured or clear, so they blend in with the natural tooth. They also feel quite natural, so we may soon forget they are there, even as they continue to work.

Many older children had sealants put on their adult molar teeth. Often they are unaware that this procedure was done. The sealants remain in place for 5 to 10 years before they need replacing.

Unfortunately, sealants can only be applied to rough surfaces, so they are unsuitable for front teeth.

Preventative dentistry means taking steps now to prevent problems in the future. Sealants prevent tooth decay.
