What is tooth decay?
Tooth decay is a common problem that occurs when acids in your mouth dissolve the outer layers of your teeth. It is also known as dental decay or dental caries.
Signs and symptoms:
- Sensitivity to hot, cold or sweet
- Dark spots appearing on your teeth

How to prevent tooth decay:

- Brush your teeth for at least two minutes with a fluoride toothpaste twice a day.

- Try to cut down on sugary food and drinks, particularly between meals or within an hour of going to bed.
How tooth decay is treated:
If you see your dentist when the decay is in the early stages, your dentist may apply a fluoride varnish to the area to help stop further decay. If the decay has worn away the outer layer of your tooth and caused a cavity, your dentist will remove the decay and place a fill
