Dental crowns are a common solution for restoring damaged teeth, providing both functional and aesthetic benefits. They are particularly effective when our Southgate, MI, dentists need to treat teeth compromised by decay, fractures, or extensive fillings. Among the various types of crowns available, traditional porcelain crowns are favored for their durability and natural appearance. However, a common question that arises among patients is whether cavities can still occur under or around a crown. 

Here’s the answer to that question plus essential insights into how you can maintain optimal oral health with one or multiple dental crowns.

A Review of Dental Crowns

A dental crown is a cap that is placed over a tooth to restore its shape, size, strength, and appearance. Porcelain crowns are crafted to blend seamlessly with the natural teeth, offering a robust and aesthetically pleasing solution. The process involves reshaping the affected tooth, taking an impression for the custom crown, and then cementing the crown onto the tooth. This procedure effectively protects the tooth from further damage and decay.

Can Cavities Form Under a Dental Crown?

While a dental crown itself cannot develop a cavity because it is made from materials like porcelain, the tooth underneath it remains susceptible to decay. In fact, cavities under crowns can still occur due to:

1. Marginal Decay: The most common area for decay is at the margin where the crown meets the natural tooth. If this junction is not properly sealed or if oral hygiene is inadequate, bacteria can infiltrate and cause decay at the base of the crown.
2. Poor Oral Hygiene: Neglecting proper brushing and flossing can lead to plaque accumulation around the crown. This plaque harbors bacteria that produce acids, which can penetrate the gum line and reach the natural tooth beneath the crown.
3. Cement Erosion: Over time, the cement that holds the crown in place can erode or wash away, creating small gaps that allow bacteria to enter and attack the tooth.

Signs of Decay Under a Crown

Recognizing the signs of decay under a crown is crucial for timely intervention. Letting decay sit there untreated can be potentially harmful for the rest of your mouth and put the tooth itself at risk of a repeat root canal procedure or if the damage is too severe, tooth extraction.

Don’t wait and pay attention to these symptoms: 

• Sensitivity to hot or cold temperatures
• Pain or discomfort when biting or chewing
• Swelling or tenderness in the gums around the crowned tooth
• Visible changes in the color or fit of the crown

If you experience any of these symptoms, it is important to give our Southgate, MI, dental office a call promptly so we can get an appointment set up for you.

Preventing Cavities Under Dental Crowns

Maintaining excellent oral hygiene is the best way to prevent cavities under a dental crown. Here are some key tips:

1. Regular Brushing and Flossing: Brush your teeth at least twice a day with fluoride toothpaste and floss daily to remove plaque and food particles from between your teeth and around the crown.
2. Use Mouthwash: An antimicrobial mouthwash can help reduce the bacterial load in your mouth, providing an extra layer of protection against decay.
3. Routine Dental Check-Ups: Regular visits to our dentists for teeth cleanings and check-ups are essential. We can monitor the condition of your crown and the underlying tooth, catching any signs of decay early.
4. Avoid Sugary Foods and Drinks: Reducing your intake of sugary and acidic foods and beverages can help prevent plaque buildup and subsequent decay.

Don’t Forget About Your Crowns

While dental crowns are highly effective, they do not render the underlying tooth immune to cavities. Our dentists in Southgate, MI, urge you to still practice diligent oral care and attend regular dental check-ups to reduce the risk of decay and ensure the longevity of your dental crown.
