What is a cavity?

A cavity (also referred to as a dental carie) is a hole in the tooth that can grow bigger and deeper over time, resulting in tooth decay. They are usually caused by the buildup of acid-plaque, a sticky, slimy substance on the teeth made up of bacteria. This acid-plaque occurs when bacteria feast on sugars present in the mouth.


Effects of a cavity

If left unchecked, cavities can grow in size, weakening the structure of the tooth and eventually resulting in the development of painful abscesses, tooth decay, and even tooth loss. The cavity could get larger and eventually affect the tooth root if it’s not repaired with a filling. If you catch cavities early, you can greatly reduce the likelihood of tooth loss.


  • Reduce your consumption of refined dietary sugars (which can be found in candy, soda, and processed foods).
  • Eat nutritious and balanced meals and limit snacking.
  • Remove dental plaque from the surface of the teeth every day by brushing, flossing, and using antibacterial mouthwashes.
  • Always use a fluoride toothpaste.
  • Children should have a dental sealant treatment as soon as their molars erupt. In this procedure, a sealant is applied to the pits and fissures (grooves) of the teeth to create a smooth surface that is easy to brush.
  • Be vigilant about monitoring your dental health and schedule a dental checkup every six months.
