Can You Get a Cavity Under a Crown?

Sep 06, 2023

Are you concerned about possibly developing a cavity under a dental crown? It’s a valid question, especially if you have a crown or are considering getting one. Dental crowns are frequently employed to strengthen and safeguard decayed teeth. Understanding the potential risks and properly caring for your oral health is essential. We will explore the topic of cavities under dental crowns and provide you with valuable insights. Let’s dive in and find out if getting a cavity under a crown is possible.

Introduction: Understanding Dental Crowns

Dental crowns, or tooth caps, are prosthetic devices that protect damaged or weakened teeth. They are designed to restore a tooth’s shape, size, strength, and appearance, enhancing its functionality and aesthetics. Dental crowns are made from porcelain, ceramic, metal alloys, or a combination. When properly placed, a crown can provide long-lasting support and protection to a tooth.

How Dental Crowns Work

Dental crowns near you are custom-made to fit over a prepared tooth or a dental implant. To make room for the crown, a small portion of the tooth’s structure is removed during the procedure. Once the tooth is reshaped, an impression is taken, which serves as a mold for the dental laboratory to fabricate the crown. The crown is cemented onto the tooth, covering it above the gum line. It is a durable outer shell, strengthening and protecting the underlying tooth structure.

Can You Get a Cavity Under a Dental Crown?

The good news is that the crown is resistant to cavities since it is made from materials that do not decay. However, the area where the crown meets the natural tooth is susceptible to dental caries. This junction, known as the margin, can develop gaps or openings over time, allowing bacteria to infiltrate and cause decay. Although the crown cannot decay, the tooth beneath it is still vulnerable.

Factors That May Contribute to Cavities Under Crowns

Several factors can increase the risk of developing a cavity under a dental crown. These include:

  1. Poor Oral Hygiene: Inadequate brushing and flossing may lead to plaque buildup, contributing to cavity formation.
  2. Tooth Decay: If the underlying tooth structure had existing decay before the crown placement, it can progress and lead to further damage.
  3. Improper Fit: If the crown does not fit snugly against the tooth, it can create gaps or openings that facilitate bacterial invasion.
  4. Fractured Crown: A cracked or chipped crown can compromise its integrity, allowing bacteria to reach the underlying tooth.

Maintaining Good Oral Hygiene with Dental Crowns

Maintaining good oral hygiene practices is essential to minimize the risk of developing cavities under dental crowns. Here are some tips to follow:

  • Brush your teeth at least twice a day using fluoride toothpaste.
  • Floss daily to remove plaque and debris between your teeth and the crown.
  • Rinse with an antimicrobial mouthwash to help reduce bacterial growth.
  • Regularly visit your dentist for crowns near you for professional cleanings and check-ups.
  • Avoid excessive sugary foods and drinks, as they can contribute to tooth decay.

Signs and Symptoms of Cavities Under Crowns

Detecting cavities under dental crowns can be challenging since they are invisible to the naked eye. However, certain signs and symptoms may indicate a problem. These include:

  • Increased tooth sensitivity to hot or cold stimuli
  • Discomfort or pain when biting down
  • Persistent bad breath or an unpleasant taste
  • Swelling or inflammation around the gum line

If you experience these symptoms, you must schedule an appointment with your emergency dentist in Dixon, IL.

Prevention Tips to Avoid Cavities Under Crowns

Prevention is always better than cure when it comes to dental health. Here are some preventive measures to help you avoid cavities under dental crowns:

  1. Maintain a consistent oral hygiene routine, including brushing, flossing, and rinsing.
  2. Limit consumption of sugary and acidic foods and drinks.
