Dental Decay

Dental Decay ( also known as Dental Caries ) is a disease where tooth substance is destroyed. It literally 'rots' away. It is one of the most common diseases in the world. Dental Decay in front teeth can be very disfiguring.

Some decay is obvious. However it can also penetrate teeth very quietly without you knowing. In molar teeth especially, decay can be difficult to spot and can penetrate quite deeply. By the time it is discovered, the tooth can be seriously weakened. Dentists usually take x-rays called "bitewings" every 2 to 3 years to check on molar teeth.

Teeth with decay do become more sensitive to cold. However, by the time you get toothache, the decay is usually close to the nerve chamber in the middle of the tooth. In order to save the tooth, it is often necessary to remove the nerve and complete a root canal treatment. It is far better to find decay in the early stages ! Regular check ups can prevent more serious problems later.

• Eating or drinking foods containing sugar or refined carbohydrate.
• Inefficient cleaning of your teeth leaving plaque behind.
• The bacteria in plaque convert the sugar into acid.
• The acid destroys tooth enamel and allows bacteria to enter.

How can I prevent decay ?

• Reduce how often you eat or drink food containing sugar or refined carbohydrate.
• If you do have anything with sugar, drink water afterwards to help eliminate the acid.
• Chewing gum has been shown to be quite beneficial because it stimulates more saliva.
• Brush your teeth very carefully and floss them daily.

• The dentist can warn you if you are missing any areas and leaving plaque behind.
• Periodic x-rays can pick up many early signs of decay before it weakens the tooth.
