Ask Dr. McDonald: what are cavities and why do we get them?

Escondido dentist Dr. Rabee McDonald knows one word nobody wants to hear when they visit Lifetime Smiles is "cavity." But what exactly is a cavity and how do you get one? A cavity is a hole that develops in a tooth when the tooth begins to decay. It’s important to get a cavity filled as soon as it’s detected so that it does not grow bigger.

So, what causes a cavity? A cavity is caused by plaque, a sticky substance that forms on the tooth as a result of germ and bacteria build-up. Plaque is acidic and as it clings to your teeth the acids eat away the outside of the tooth (also called the enamel) and a hole is formed.

Yes, cavities can be repaired at Lifetime Smiles, but here are a few simple steps you can take to prevent cavities at home:

• Brush your teeth with fluoride toothpaste at least twice daily
• Gently brush your gums to keep them healthy (use soft bristles)
• Floss your teeth at least once a day to remove plaque and food that may be caught between the teeth where your toothbrush can’t reach
• Limit the amount of soda and sugary treats you eat/drink
• Be sure to visit Drs. McDonald or Prais every six months for a check-up (or as recommended)
