What Are Cavities?

Cavities are holes that form in the hard outer layer of your teeth, known as enamel.

They develop when bacteria and food particles combine to form a sticky film called plaque, which then begins to eat away at the enamel. Plaque contains an acid that wears down the enamel, resulting in cavities.

Over time, cavities can cause discomfort and pain. If left untreated, they can also lead to tooth decay and even tooth loss!

What Are the Symptoms of Cavities?

Early signs of cavities include sensitivity to hot or cold foods, discoloration of teeth (typically brown or black spots), visible holes in teeth, and persistent bad breath.

If you notice any of these symptoms, it's important to visit your dentist right away. They can help diagnose the problem and recommend treatment options.

How Do I Know if I Have a Cavity?

The only sure way to know if you have a cavity is by visiting your dentist.

Your dentist will be able to examine your mouth and take an x-ray of the affected area.

Symptoms of cavities include tooth sensitivity, bad breath, and pain when chewing or drinking hot or cold drinks.

Are Cavities Contagious?

No, cavities are not contagious.

Cavities occur when plaque forms on the surface of teeth, breaks down enamel, and causes decay. Bacteria that grow in the mouth due to poor oral hygiene, eating sugary foods, and other lifestyle choices cause this form of tooth decay.

Therefore, cavities cannot be spread from person to person like an infectious disease. However, it is important to practice good oral hygiene habits, such as brushing your teeth twice a day and flossing regularly to prevent cavities from forming.

What Are the Treatments for Cavities?

Treatment for cavities depends on the severity of the decay.

Mild cases may only require a basic dental filling, while more advanced cavities may require root canals or other treatments.

Your dentist will be able to provide you with more information about the best course of treatment for your particular case.

How Much Does a Cavity Filling Cost?

The cost of a cavity filling will vary depending on the type of treatment needed and your insurance coverage.

Generally, basic dental fillings can range anywhere from $50 to $300 per tooth.

Be sure to check with your dentist or insurance provider for more information about potential costs associated with cavities and treatments.

How much is a cavity filling without insurance?

Without insurance, the cost of a cavity filling can range from $50 to $300 per tooth. The exact cost will depend on the type of treatment needed and other factors. To get an accurate estimate, it is best to contact your dentist or insurance provider for more information.

What Happens if I Don’t Get a Cavity Filled?

If a cavity is not treated, it can cause damage to the tooth and surrounding tissue. This can result in pain, infection, and even tooth loss if left untreated.

It is important to get cavities filled as soon as possible to prevent any further damage or complications.

It is also recommended that you practice good oral hygiene habits.

What’s the Best Way to Prevent Cavities?

The best way to prevent cavities is by practicing good oral hygiene habits like brushing twice daily, flossing daily, and using an antibacterial mouthwash.

Additionally, it's important to limit your intake of sugary and acidic foods as they can lead to the development of cavities.

Regular visits to your dentist are also recommended.

Will My Cavity Go Away on Its Own?

No, cavities will not go away on their own and must be treated by a dentist to keep the tooth and surrounding tissue healthy.

If left untreated, the cavity can get larger and cause further damage to the tooth. This can result in pain, infection, and even tooth loss. Therefore, it is important to get cavities treated as soon as possible.

Do Cavities Occur Between Teeth?

Yes, cavities can occur between teeth where brushing and flossing are difficult to reach.

These cavities are known as interproximal cavities. They are often difficult to detect with a visual inspection and may require special dental X-rays to diagnose.

Regular dental check-ups and cleanings with a dentist are recommended to ensure all cavities, including those between teeth, are detected and treated promptly.


Can Cavities Be Prevented?

Yes, practicing good oral hygiene, such as brushing your teeth twice a day and flossing once a day can prevent cavities.

Limiting sugary foods and drinks, eating a balanced diet, and visiting the dentist for regular check-ups and cleanings can also help to prevent cavities from forming.

Sealants and fluoride treatments may also be recommended to protect teeth from decay.


In conclusion, it is important to understand the causes and symptoms of dental cavities to keep your teeth healthy.

Regular visits to the dentist and proper oral hygiene are key components to keeping your teeth cavity-free.

By understanding what leads to cavities and taking preventive measures, you can help protect your teeth from developing any cavities in the future.
