Can Dental Crowns Get Cavities?

Dental crowns are a common and highly effective solution for restoring damaged or weakened teeth. They provide protection, improve function, and enhance the appearance of a tooth and the smile overall. Because dental crowns typically cover a natural tooth — with the exception of implant-supported crowns — patients may have questions about whether crowned teeth can get cavities. While a dental crown itself can't develop a cavity, the natural tooth beneath it is still vulnerable to decay if not properly cared for. At Melton Dental in Helena, MT, Dr. Sean Melton is committed to helping patients preserve their oral health and maintain their dental restorations for as long as possible. Whether you have a crown or are considering one, it's important to understand how to maintain your dental restoration and prevent decay. Keep reading to learn more about how cavities can form under dental crowns and how you can avoid them.

Can you get a cavity on a tooth with a crown?

Dental crowns are made from durable materials like porcelain, ceramic, or metal, which cannot develop cavities. However, the natural tooth structure underneath the crown can still be susceptible to decay if proper oral hygiene isn't maintained. Cavities can form at the margin, or edge, where the crown meets the natural tooth. This area is particularly vulnerable if plaque and bacteria build up, leading to decay over time. Even though the crown can't get a cavity, it's essential to still care for the crowned tooth just as you would a natural tooth to prevent future dental problems.

How do you get a cavity under crown?

Cavities can develop under a dental crown for several reasons, including:

• Poor oral hygiene
• Bacteria and plaque buildup
• Ill-fitting or loose crowns
• Receding gums
• Gaps between crowns

How can I prevent cavities under a crown?

The primary key to preventing cavities under a dental crown is maintaining good oral hygiene and scheduling regular dental visits. Here are a few tips to help keep your crowned tooth —and the rest of your smile — healthy and strong over time:

• Brush your teeth at least twice a day with fluoride toothpaste
• Floss daily, making sure to clean around the crown and at the gumline
• Use an antibacterial mouthwash to reduce plaque and bacteria buildup
• Adhere to regular dental cleanings and exams to monitor your crown and surrounding teeth

By following these steps, you can protect your crowned tooth from cavities and extend the life of your dental restoration.

What happens if I get a cavity under my crown?

If a cavity forms under your dental crown, it's important to address it as soon as possible to prevent further damage. In many cases, Dr. Melton may need to remove the crown to treat the underlying decay. Once the cavity is cleaned and the tooth is restored, a new crown can be placed. Delaying treatment for a cavity under a crown can lead to more severe dental issues, including infection or the need for a root canal. Regular check-ups at Melton Dental allow Dr. Melton to detect early signs of decay and treat issues before they worsen. If you have any concerns about a possible cavity under a crown or symptoms of a cavity, like tooth pain, a loose crown, or something else, don't hesitate to call our friendly team to schedule an appointment at your earliest convenience.
