Cavities, also known as tooth decay or caries, are among the most common dental problems people face. A cavity is a small hole that forms in the enamel (the outer layer of the tooth) and can grow larger over time if left untreated. Cavities are caused by a buildup of plaque (a sticky film of bacteria) that produces acids that eat away at the tooth’s surface. The acid dissolves the mineral in the tooth, creating a hole in the enamel.
What Causes Cavities?
The primary cause of cavities is bacteria in the mouth. The bacteria live in the plaque that forms on the teeth and gums. The bacteria feed on sugars and starches in our food, producing acids that attack the teeth. The more sugar and starch in the diet, the more plaque will form and the greater the risk of cavities.
Another factor that can increase the risk of cavities is poor oral hygiene. Brushing and flossing regularly can help remove plaque and prevent cavities, but if you do not brush and floss properly, the plaque can harden into tartar, which a dentist can only remove.
Who is at Risk for Cavities?
Anyone can get cavities, but some people are at higher risk than others. Children and teenagers are particularly at risk because their teeth are still developing and are more susceptible to decay. People with a high-sugar diet and those who do not brush and floss regularly are also at greater risk.
Cavities can be painful, but many people do not experience symptoms until the cavity is large. Some of the symptoms of cavities include:
- Tooth sensitivity when eating or drinking hot or cold foods and drinks
- Pain when biting or chewing
- A visible hole or pit in the tooth
- A brown or black spot on the tooth
Diagnosis and Treatment of Cavities
The best way to diagnose a cavity is to have a dental checkup. During a checkup, your dentist will examine your teeth and take x-rays to determine if you have cavities. If a cavity is found, your dentist will clean it out and fill the hole with filling material, such as silver, gold, or composite resin.
The best way to prevent cavities is to maintain good oral hygiene and limit the amount of sugar and starches in your diet. Here are some tips to help you prevent cavities:
- Brush your teeth twice a day with fluoride toothpaste
- Floss daily to remove plaque from between your teeth and along the gumline
- Use mouthwash to kill bacteria and freshen your breath
- Drink plenty of water to help rinse your mouth and teeth
- Limit sugary drinks and snacks
- Visit the dentist regularly for checkups and cleanings
