Do Teeth Go Bad Under Crowns?

A dental crown is a cap that fits over a tooth to bring back its shape, strength, and function. Crowns can be made from porcelain, ceramic, metal, or a combination of these materials.

While a crown covers the tooth, it does not fully seal it from the mouth. The place where the crown meets your natural tooth at the gumline is called the margin, and this is where issues can sometimes begin.

Teeth under crowns can develop problems if bacteria get in near the edge. Plaque and food can collect around the crown, and if you don’t clean well, this can cause decay under the crown. Because the crown covers the tooth, you might not notice the decay right away.

Gum disease can also cause problems for teeth with crowns. If your gums pull back from the tooth, more of the root is exposed, making it easier for bacteria to reach these sensitive spots.

A loose or damaged crown can also be a problem. If the crown cracks or moves, small gaps can form. Bacteria can get into these spaces and may cause decay or infection.

Many people ask how to tell if a tooth under a crown is having problems. Here are some common signs to look for:

• You feel pain when you bite down or chew.
• Your tooth is sensitive to hot or cold foods and drinks.
• The gums around your crown are swollen or sore.
• You notice a bad taste in your mouth.
• Your crown feels loose.

If you notice any of these symptoms, make an appointment with your dentist. Getting evaluated early can prevent the problem from getting worse.

There are a few reasons why decay can develop under a dental crown:

• Not brushing and flossing well enough.
• Missing regular dental checkups.
• Wearing an old crown that doesn’t fit properly anymore.
• Grinding or clenching your teeth.
• Having a dry mouth, which means you have less saliva.

Saliva helps clean away bacteria. If your mouth stays dry, your risk for tooth decay increases.

Individuals with crowns often worry about the health of their teeth beneath them, but most issues can be avoided by maintaining good oral hygiene.

Here are some ways to keep your crowned teeth healthy:

Brush Your Teeth Twice a Day

Use fluoride toothpaste and brush gently around your crown and along the gumline.

Floss Every Day

Gently slide floss under the edge of your crown to remove any food or plaque that may be stuck.

See Your Dentist Regularly

Regular checkups let your dentist make sure your crown fits well and catch any early signs of decay.

Avoid Hard Foods

Chewing ice or hard candy can damage crowns and cause cracks.

Wear a Night Guard if You Need One

If you grind your teeth at night, a guard can help protect both your crowns and your natural teeth.

Teeth under crowns can have problems if they are not cared for properly. Brushing, flossing, and seeing your dentist regularly can help prevent these issues. With good care, a dental crown can last for many years, but how long it lasts depends on how well you protect the tooth underneath.
