The prevention of tooth decay (also known as dental caries) can be implemented in two complementary ways. Both of these ways are aimed at providing a hostile environment for the disease and, in particular, stopping the bacteria that cause the tooth decay from thriving. One way to help prevent tooth decay is through modification of the diet of the patient and the other way is through the direct physical modification of the oral environment of the patient.

The causative agent at work in tooth decay is an acid-producing bacteria, such as Streptococcus mutans and Lactobacilli, for example. They have their damaging effects when they are allowed to thrive because of the presence of fermentable carbohydrate. These fermentable carbohydrates could include, for example, glucose, fructose or sucrose.

The way that the acid-producing bacteria act is by collecting in a biofilm on the teeth and gums in a substance that will be familiar to many as plaque. To understand why this is a problem at the heart of tooth decay it must be pointed out that the teeth are constantly demineralizing and remineralizing from the saliva in the mouth. When acid is introduced into the mouth by the bacteria, demineralizing occurs at a faster rate than remineralization occurs, thus causing the net mineral loss on the surface of the tooth that is tooth decay.

One reason why such microorganisms may have been able to thrive in the patient's mouth and as a result increase the acid level in the mouth is that there has been a change in the diet of the patient that has provided more fermentable carbohydrates for use by the bacteria. By implementing a less sugary diet the patient can help to return the acidic balance in the mouth by removing the source of fermentation that is being used by the bacteria.

Poor oral hygiene is another possible reason that could be responsible for the build up of plaque, and the tooth decay that it leads to, in the patient's mouth. Regular brushing with a good toothpaste and a good toothbrush (such as a sonic toothbrush, for example), flossing, the use of interdental brushes, and the use of a good mouthwash can all be useful, and potentially complementary, approaches to help to prevent tooth decay. Regular visits to the dentist are also vital in helping to prevent tooth decay, through the active removal of plaque and the active remineralization of the teeth, and also to identify when problems are present and may require more attention.
