Introduction
Tooth decay, also known as dental decay or dental caries, is when acids in your mouth dissolve the outer layers of your teeth.
Symptoms of tooth decay
Tooth decay may not cause any symptoms until it has reached an advanced stage. This is why it is important to have regular check-ups with your dentist.
Causes of tooth decay
Tooth decay is caused over time by plaque forming on your teeth. There are several risk factors which increase the chances of this happening.
Diagnosing tooth decay
A dentist should be able to spot tooth decay in its initial stages by physically examining your mouth during a dental check-up.
Treating tooth decay
If your decay is in the early stages, your dentist may apply a fluoride varnish to the area. Lowering your intake of sugar is also important.
Complications of tooth decay
If you have a lot of plaque on your teeth, bacteria can infect your gums as well as the tissue and bones that support your teeth.
Preventing tooth decay
Maintaining good oral hygiene is one of the most effective ways to prevent tooth decay. Brush your teeth at least twice a day with fluoride toothpaste.
