Cavity Q & A

What causes cavities?

Cavities are caused by a buildup of plaque on the enamel of your teeth. Plaque is a thin, sticky film that forms from bacteria that converts sugars in the foods you eat into acids. These acids then attack your teeth’s enamel, which is the protective hard outer layer of your teeth.

If plaque isn’t removed regularly, it traps these acids next to the enamel, causing the enamel to break down over time. Cavities form when the enamel develops tiny holes that increase in size and lead to tooth decay. Habits and lifestyle factors that make tooth decay more likely include:

  • Poor oral hygiene
  • Smoking
  • Insufficient intake of fluoride
  • Eating too much sugar
  • Eating too many starchy foods, which are broken down into sugars by saliva
  • Drug abuse

Cavities can also be caused by certain chronic diseases or by taking medications that reduce the amount of saliva you produce.

What are the symptoms of a cavity?

In the early stages of a cavity, you may not realize anything is wrong with the affected tooth, but the severity of your symptoms can increase over time and you may notice:

  • An increased sensitivity in your tooth
  • The enamel looks slightly discolored

If a cavity spreads into the dentin inside your tooth, these symptoms can get worse, and you may see a dark spot on your tooth. If the cavity reaches the sensitive pulp in the center of your tooth, it can cause a good deal of pain. You may also notice an unpleasant taste in your mouth or find you have bad breath.

What treatments are available for cavities?

How Dr. Lin decides to treat your cavity depends on the stage of decay in your tooth. Common procedures performed at his Livermore office include:


Dr. Lin removes the affected part of your tooth and replaces it with a filling made of porcelain, composite resin, silver amalgam, or gold.

Crowns and caps

If Dr. Lin needs to remove so much of your tooth that it can’t hold a filling, he can restore your tooth using a crown or cap.

Root canal

If the pulp is affected, Dr. Lin may need to remove it along with the nerve and then seal it with a crown.

How can I prevent cavities from forming?

Good dental hygiene and regular checkups with Dr. Lin are essential to protect your oral health and prevent cavities. You should:

  • Brush your teeth twice a day
  • Use a fluoride toothpaste
  • Floss at least once a day
  • Reduce your sugar intake
  • Make an appointment to see Dr. Lin every six months for a preventive checkup and cleaning

You can also talk to Dr. Lin about fluoride treatments and dental sealants that can help prevent tooth decay. If you’re in Livermore or the surrounding area, book an appointment online or over the phone with Brent C Lin, DDS today.
