Treat Tooth Decay at Home

Tooth decay (or cavity) results from a bacterial infection on the tooth surface. Unlike other diseases, tooth decay is not life threatening and is highly preventable. It affects most people to some degree during their lifetime. What causes tooth decay?
Tooth decay occurs when teeth are frequently exposed to foods containing carbohydrates (starches and sugars) in the presence of cavity-causing bacteria. This cavity-causing bacteria lives in the mouth and forms plaque, which leads to decay. Only three types of the over 300 bacteria that live in the mouth will assist the decay process.

The bacteria then interacts with deposits left on teeth from sugary and starchy foods to produce acids. The acids then damage tooth enamel over time by thinning the mineral structure of teeth, producing tooth decay and weakening the teeth. How are cavities prevented?

The acids formed by plaque can be counteracted by saliva, which acts as a buffer and remineralizing agent. The best way to prevent cavities is to brush with a fluoride toothpaste, limit sweets and floss.

Fluoride is a natural substance which helps build up (or remineralize) tooth structure and make it more resistant to future breakdown. Sealants can prevent decay in the pits and fissures of the tooth that fluoride can not reach.

How can re-mineralization treatment help teeth?

Re-mineralzation builds up the weakened enamel that has become porous - tiny tubes have formed in the enamel, and remineralzation helps strengthen the tubes to make enamel stronger.

Even if the weakened enamel does develop into a cavity that needs to be filled, the remineralized tooth will have less enamel and tooth structure removed before it is prepared to be filled.

Who is at risk for cavities?

Some people have a greater decay risk factor than others because of bacteria levels. Others at risk:



People with a diet high in carbohydrates and sugary foods
Those that live in communities without fluoridated water
People with fillings - the area around a restored portion of a tooth is a good breeding ground for bacteria
Individuals with dry mouth
Children and senior citizens are the two groups at highest risk
