What is a Cavity?

Cavities are spaces in the teeth caused by decay or injury. Cavities can be small or large, and can vary in shape, size and number. Cavities can form at any stage of tooth development, but are most common in young adults. Cavity frequency is strongly associated with diet and lifestyle choices.

What Causes Cavities?

Cavities are caused when a section of your tooth falls out and a cavity forms. Cavities form in the center of the tooth, usually brightly colored on an x-ray. When decay (a fungus) eats away at the tooth’s outer layer, the decay can break through to underlying dentin. This is what causes the bright color on x-rays. If decay breaks through to pulp, black spots or lines are visible on an x-ray.

How to Prevent Cavities

A loss of tooth material causes cavities. When this happens, the dentin in the tooth becomes exposed. The bacteria that normally inhabits the gum tissue can easily enter the tooth and cause cavities. You can do several things to prevent cavities, including brushing and flossing regularly, eating a balanced diet, and getting regular dental check-ups.

Signs and Symptoms of a Cavity

If you have a cavity, you are likely experiencing some of the following signs and symptoms:

  1. toothache or pain when biting into food.
  2. difficulty chewing or swallowing.
  3. swelling or redness around the affected tooth.
  4. leaking of saliva or toothpaste.

How to Fix a Cavity

When a cavity exists in an tooth, the surrounding tooth structure may be affected. The cavity can affect the way that the tooth looks on an x-ray. A common symptom of a cavity is when coffee or tea gets trapped in between teeth and causes a black spot on an x-ray. Although small cavities may not require treatment, larger cavities may require filling with dental cement or a dental restoration.

Treatment Options for Cavities

A cavity on an x-ray is caused when the bone inside the tooth is exposed. The space between the tooth and the bone looks like a dark spot on an X-ray. There are many different treatments for cavities. Some people have to have their teeth extracted, but other options exist. Here are some of the most common:

Cavity filling

This is usually done with a dental dam (a thin piece of plastic or metal that fits over the top of the tooth) and a filling material. The dentist Brushs or suctions plastic onto the exposed area of the tooth and then fills it with a material like rubber, porcelain, or stainless steel. Dental dams protect your dental work from food and drink while you eat and drink.

Cavity restoration

This is when dentists repair a cavity before filling it. They use either natural or artificial materials to close up the hole in your teeth. Sometimes they use a combination of both techniques to get the best results.
