Treatment for Tooth Decay in Teeth with Crowns

How to Treat Tooth Decay in Teeth with Crowns

1- Understanding Tooth Decay Under Crowns

When you get a dental crown, it's typically because you have a damaged or decayed tooth. Crowns are designed to protect and restore the structure of the tooth. However, despite their protective function, tooth decay can still develop underneath the crown over time. This often occurs due to poor oral hygiene, gum recession, or if the crown becomes loose or cracked, allowing bacteria to enter and cause decay.

Tooth decay under crowns can be problematic because it may not be visible to the naked eye. Often, patients are unaware of the issue until they experience symptoms such as pain, sensitivity, or swelling. It's important to recognize the signs of decay early so that treatment can begin before the decay spreads further and causes more significant damage to the underlying tooth structure.

2- Causes of Tooth Decay Under Crowns

Several factors can contribute to the development of decay under a crown, including:

2.1 Poor Oral Hygiene

If you don't properly clean your teeth and gums, plaque can accumulate around the edges of the crown. Plaque contains bacteria that can attack the tooth underneath, leading to decay. Over time, this buildup can erode the tooth structure beneath the crown, resulting in cavities.

2.2 Gum Recession

As gums naturally recede with age or due to periodontal disease, the base of the crown may become exposed. This can create space for bacteria to accumulate, which can lead to decay in the exposed tooth area.

2.3 Crown Damage or Poor Fit

Sometimes, a crown may become damaged or loose, allowing bacteria to infiltrate and cause decay. A poorly fitted crown might not seal the tooth completely, allowing gaps that lead to further decay.

2.4 Previous Tooth Decay

If the tooth underneath the crown had significant decay before the crown was placed, the remaining tooth structure might still be vulnerable. Over time, the material may wear down, allowing bacteria to reach the decayed area.

3- Symptoms of Tooth Decay Under Crowns

Tooth decay under crowns often develops slowly and can be asymptomatic at first. However, as the decay progresses, you may begin to experience some common signs:

• Pain or Sensitivity: Increased sensitivity to hot or cold temperatures or dull pain in the affected tooth.
• Bad Breath or Unpleasant Taste: Foul odor or taste in the mouth can indicate infection caused by decay under the crown.
• Visible Dark Spots or Cracks: If the crown becomes loose or cracked, you might notice discoloration or a visible gap along the edges of the crown.
• Swelling or Tender Gums: Swelling and discomfort around the crown may be a sign of infection or decay.

If you notice any of these symptoms, it’s crucial to consult a dentist promptly to avoid further damage or complications.

4- Treatment Options for Decay in Teeth with Crowns

When tooth decay is discovered under a crown, there are a few possible treatment options, depending on the extent of the decay and the condition of the crown. Here's what your dentist might recommend:

4.1 Removing and Replacing the Crown

The most common treatment for tooth decay under a crown is to remove the crown and assess the extent of the damage. If the decay is minor, the dentist may clean the tooth, fill in the cavity, and then place a new crown. If the decay has spread significantly, further procedures, like a root canal, may be necessary to save the tooth.

4.2 Root Canal Treatment

If the decay has reached the inner pulp of the tooth, a root canal may be required. This procedure involves removing the infected tissue inside the tooth, cleaning it, and sealing it before placing a new crown. Root canal therapy is often the best option for preserving a tooth with severe decay beneath a crown.

4.3 Cavity Filling

If the decay is limited to a small area and hasn’t reached the pulp, your dentist may be able to remove the decayed tissue and fill the cavity with a dental filling material. Afterward, the original crown may be re-cemented or a new one may be placed.

4.4 Crown Replacement with a Larger Restoration

In some cases, if the tooth has become too damaged to support a traditional crown, your dentist might recommend a larger restoration, such as an inlay or onlay. These options offer additional strength and durability, especially if there’s a substantial amount of decay present.

5- How to Prevent Tooth Decay Under Crowns

Prevention is always better than treatment, and there are several ways to minimize the risk of tooth decay under crowns:

• Maintain Good Oral Hygiene: Brush your teeth at least twice a day with fluoride toothpaste and floss daily to remove plaque and food particles from around the crown.
• Regular Dental Checkups: Visit your dentist regularly for cleanings and exams. Your dentist can identify early signs of decay and address them before they become more serious.
• Avoid Sugary Foods and Drinks: Reduce your intake of sugary foods and beverages, which contribute to plaque buildup and increase the risk of tooth decay.
• Use Mouthwash: An antimicrobial mouthwash can help reduce bacteria and prevent plaque buildup around crowns.
• Protect Your Crown: Avoid chewing on hard objects or using your teeth to open packaging, as this can cause crowns to crack or loosen.

6- Real-Life Case: Treatment for Tooth Decay in a Crowded Tooth

One patient, Emily, came to her dentist after experiencing persistent sensitivity and discomfort around a crowned tooth. The dentist discovered that the tooth underneath the crown had begun to decay due to a poor fit, which allowed bacteria to seep in. After carefully removing the crown and evaluating the damage, Emily needed a root canal to save the tooth, followed by a new, properly fitted crown. Thanks to the timely intervention, Emily avoided further damage and now follows a strict oral care routine to prevent future issues.

7- When to Seek Professional Help

If you suspect that you have tooth decay under a crown, don’t wait for the situation to worsen. Early intervention can save your tooth and prevent further complications. Consult a dentist immediately if you experience any of the symptoms of decay, such as pain, swelling, or visible damage to the crown. Your dentist will evaluate the condition of the tooth and recommend the best course of action to restore your dental health.
