Tooth cavities: symptoms, causes

What are cavities?

A cavity, also called a cavity, is a hole that forms in your tooth. Cavities start small and gradually become larger when left untreated. Because many cavities don’t cause pain at first, it can be hard to realize there’s a problem. Regular dental appointments can detect tooth decay early.

Tooth decay and tooth decay are some of the most common health problems in the world. Anyone with teeth can develop cavities, including babies. Finding out you have a cavity can come as a surprise.

This is especially true if you think you have a good oral hygiene routine. However, even if your dentist delivers this news, there are ways to treat a cavity and prevent new ones from forming.

Dental cavity symptoms

The symptoms of a cavity depend on the severity of the decay. They include:

  • tooth sensitivity
  • toothache
  • a visible hole in your teeth
  • black or white stains on your teeth;
Causes of dental cavity

Tooth cavities are caused by plaque, a sticky substance that attaches to the teeth. Plaque is a combination of:

  • bacteria
  • saliva
  • acid
  • food particles

Everyone has bacteria in their mouth. After you eat or drink sugary foods, bacteria in your mouth turn the sugar into acid. Plaque starts forming on your teeth right after you eat or drink anything sugary. This is why regular brushing is important.

Plaque sticks to your teeth and the acid in plaque can slowly erode tooth enamel. Enamel is a hard, protective coating on your teeth that protects against tooth decay. As your tooth enamel weakens, your risk for tooth decay increases.

Everyone is at risk for tooth decay, but some people are at greater risk. Risk factors include:

  • too many sugary or acidic foods and drinks
  • a poor oral hygiene routine, such as not brushing or flossing daily;
  • they don’t get enough fluoride
  • dry mouth
  • eating disorders such as anorexia and bulimia
  • acid reflux, which can result in stomach acid damaging the enamel of your teeth

Cavities develop most often in the back teeth. These teeth have grooves and openings that can trap food particles. Also, these teeth are sometimes harder to reach when brushing and flossing.
