If you've been told you have a cavity, you may wonder, “Can I wait to get it fixed?”
The answer isn't always straightforward. Cavities can progress at different rates, depending on factors such as oral hygiene, diet, the location of the decay, and your individual oral health.
What starts as a small problem can become more difficult to treat if it is left untreated.

Can a Small Cavity Get Worse?

Yes. Tooth decay generally does not repair itself once a true cavity has formed.
As decay progresses, it can move deeper into the tooth. A small cavity may eventually become large enough to cause sensitivity, pain, or damage to the tooth.
That's why dentists often recommend treating cavities before they become more extensive.

How Quickly Can a Cavity Progress?

There is no exact timeline.
Some cavities may progress slowly, while others can develop or worsen more quickly. You cannot reliably determine how fast a cavity is progressing simply by how the tooth feels.
A cavity can sometimes develop without causing noticeable symptoms.

What Happens If You Ignore a Cavity?

Untreated decay can potentially lead to:

• Increasing tooth sensitivity
• Toothache
• A larger cavity
• Damage to the tooth
• Infection
• The need for more extensive dental treatment

In some cases, a tooth that could have been treated with a simple filling may eventually require more complex treatment.

Does a Cavity Always Hurt?

No.
A cavity can be present without causing pain, particularly during its earlier stages.
This is one reason regular dental examinations are important. Your dentist may identify areas of decay before you notice symptoms yourself.

What Should You Do If You Have a Cavity?

If your dentist has recommended treatment, it's best to discuss your options rather than simply waiting for pain to appear.
Depending on the size and location of the cavity, treatment may involve a filling or another type of restoration.
