What is tooth decay?
Dental caries or tooth decay, is the formation of cavities by the demineralization of the tooth by action of bacteria. The causes of caries are:
- Plaque bacteria
- Dietary sugars
- Exposure to acid attack
- Susceptible tooth surfaces
Tooth decay occurs when bacteria in plaque reacts with dietary sugars to produce acid. The production of acid by the bacteria alters the natural environment of the mouth; this environment becomes more acidic and the enamel becomes more at risk of decay.
Under normal circumstances, minerals in your saliva, as well as the fluoride that is contained in toothpaste during regular brushing, helps to decrease the risk of decay. However, for various reasons, some individuals may need additional protection. For example, people with exposed dental root surfaces are more sensitive to acid attacks.
How do I to protect my teeth against tooth decay?
Whenever there is an increased risk of tooth decay, there is an increased need for protection against it. This includes treatments at the dental practice as well as through your oral hygiene regime at home.
Visit your dentist regularly and follow their advice on how to look after your teeth and gums.
