Are you looking to know What Is a Cavity? then read this article to find out What Is a Cavity

A cavity is a tiny opening or hole in your tooth that forms due to tooth decay. It happens when acids in your mouth wear down the hard outer layer of your tooth, called enamel. If you are searching for a dental clinic near me, regular checkups can help prevent cavities and catch them early. Cavities can affect people of all ages, but you can prevent them with good brushing, flossing, and regular dental visits.
Cavities are also called dental caries.
Types of Cavities
Cavities can start on different parts of your teeth. Here are the main types:
- Smooth surface cavities: These form slowly on the flat sides of your teeth. With good brushing and flossing, you can sometimes stop or reverse them.
 - Pit and fissure cavities: These develop on the top, bumpy surfaces of your back teeth. They often begin in the teenage years and can grow quickly.
 - Root cavities: These happen when gums pull away from the teeth (called gum recession). The roots become exposed and can decay. Older adults are more at risk.
 
Who Gets Cavities?
Over 80% of Americans have at least one cavity by their mid-30s. Children are more likely to get cavities because they often eat sugary snacks and may not brush well. Adults can also get cavities, especially around old fillings or near exposed roots.
Signs and Symptoms
In the early stages, you may not feel anything. But as the cavity grows, you might notice:
- Toothache or pain
 - Bad breath
 - Tooth sensitivity to hot or cold
 - Swollen gums or face
 - A bad taste in your mouth
 
Stages of Tooth Decay
- Demineralization: White spots appear on your tooth as minerals are lost.
 - Enamel decay: The enamel breaks down, and a small hole forms.
 - Dentin decay: The decay spreads to the softer layer under the enamel, causing sensitivity.
 - Pulp damage: The decay reaches the nerves and blood vessels, causing pain and swelling.
 - Abscess: A pocket of pus forms at the root, leading to serious infection and swelling.
 
Causes and Risk Factors
Cavities form when bacteria in your mouth feed on sugary or starchy foods. The bacteria make acid, which forms plaque—a sticky film on your teeth. Plaque acids slowly break down your enamel.
Risk factors include:
- Dry mouth
 - Poor brushing habits
 - Eating lots of sugary snacks
 - Gum recession
 - Family history of decay
 
Treatment Options
Treatment depends on how bad the cavity is:
- Fluoride: In early stages, fluoride can help repair enamel.
 - Fillings: The dentist removes decay and fills the hole.
 - Root canal: For deep decay, the infected pulp is removed and the tooth is sealed.
 - Tooth removal: If a tooth is badly damaged, it may need to be pulled.
 
Prevention Tips
- Brush with fluoride toothpaste twice a day.
 - Floss daily.
 - Limit sugary snacks and drinks.
 - Visit your dentist twice a year.
 - Ask about sealants for extra protection.
