What to Do if Your Tooth is Decaying Underneath a Crown

1. Understanding Tooth Decay Under Crowns

Dental crowns are a common solution for people with damaged or decaying teeth. They act as protective caps that are placed over the tooth to restore its shape, size, and function. However, despite their effectiveness, crowns do not make the underlying tooth impervious to decay. If the tooth beneath the crown is not properly maintained, it is still susceptible to further decay, which can be problematic.

Tooth decay under a crown is a concern because it can go unnoticed for a while. Often, the symptoms are not immediately visible, and by the time you notice them, the decay may have progressed significantly. The good news is that understanding what causes decay under crowns and how to address it can help prevent serious complications.

In this article, we will explore the causes, symptoms, and treatment options for decay under crowns, as well as how you can take preventative measures to protect your oral health and your crowns.

2. Signs of Tooth Decay Underneath a Crown

Detecting decay under a crown can be challenging since the crown itself may not show visible signs of damage. However, there are several indicators that could suggest that decay is occurring beneath the surface:

• Tooth Sensitivity: If you experience sudden tooth sensitivity to hot, cold, or sweet foods and drinks, it could be a sign of decay. The decayed area may be causing the tooth’s nerves to become exposed, leading to discomfort.
• Discomfort or Pain When Biting: A decaying tooth can cause pain or discomfort when chewing or biting down. This could indicate that the tooth structure underneath the crown is compromised.
• Bad Breath: Persistent bad breath or an unpleasant taste in the mouth can be a result of bacterial growth caused by decay. The bacteria can cause an infection under the crown, leading to halitosis (bad breath).
• Visible Discoloration: In some cases, if the decay is severe enough, you may notice dark spots or discoloration around the edge of the crown where it meets the tooth.

If you experience any of these symptoms, it is important to visit your dentist as soon as possible. Early detection of decay can prevent more serious problems, such as tooth loss or the need for more invasive treatments.

3. How Does Decay Happen Under a Crown?

Tooth decay under a crown typically occurs when bacteria are able to infiltrate the area around the crown, often through a gap or poorly sealed margin. The gap may form over time due to natural wear, or it could happen immediately if the crown was not placed properly. Once bacteria enter the tooth, they begin to feed on leftover food particles and sugars, producing acid that breaks down the tooth structure.

Another reason decay may occur is due to poor oral hygiene. If you fail to properly clean your teeth and crown, plaque can accumulate, leading to the development of cavities. Even though a crown covers the visible part of the tooth, bacteria can still accumulate in areas that are difficult to clean, such as under the gumline or near the edge of the crown.

Additionally, if the tooth under the crown had an initial root canal, there is an increased risk of decay. Even though the root canal eliminates the nerve and pain sensation, it does not completely protect the tooth from bacterial growth, especially if the seal is compromised over time.

4. What to Do if Decay Is Detected Under Your Crown

If you or your dentist discover that decay has developed under your crown, the first step is not to panic. While it can be concerning, there are several treatment options available to resolve the issue.

First, your dentist will likely conduct an X-ray to assess the extent of the decay. Depending on how deep the decay has penetrated, they may recommend one of the following options:

• Replacing the Crown: If the decay is localized and does not affect the underlying tooth too much, your dentist may decide to clean the decayed area and replace the crown.
• Root Canal Treatment: If the decay has reached the tooth's pulp (nerve), your dentist may recommend a root canal. During this procedure, the decayed tissue is removed, and the tooth is sealed before a new crown is placed.
• Filling the Decayed Area: If the decay is minimal, your dentist might be able to simply remove the decay and place a filling in the affected area before putting the crown back in place.

Whatever the treatment, it’s important to follow your dentist’s instructions for post-treatment care, including good oral hygiene practices, to prevent further decay.

5. Treatment Options for Tooth Decay Under Crowns

Treatment for tooth decay under a crown depends on the severity of the decay. Here’s a breakdown of possible treatments:

• Dental Bonding: If the decay is minor, your dentist may use dental bonding material to fill in the decayed area and restore the tooth’s function.
• Crown Replacement: In cases where the decay is more extensive, the crown may need to be replaced after the decayed portion of the tooth is cleaned and reshaped.
• Root Canal and Crown: If the decay has reached the pulp of the tooth, a root canal procedure will be performed, followed by a new crown placement to restore the tooth.

Each treatment option comes with its own set of benefits, and your dentist will recommend the one that best suits your needs, taking into account the size and depth of the decay.

6. How to Prevent Decay from Developing Under Crowns

The best way to prevent decay from developing under your crown is to maintain excellent oral hygiene. This means brushing your teeth at least twice a day with fluoride toothpaste, flossing daily, and visiting your dentist regularly for checkups and cleanings.

Additionally, it’s important to maintain the integrity of your crown by avoiding habits such as chewing ice or using your teeth as tools, which can cause the crown to loosen and create gaps. If you notice any discomfort, sensitivity, or changes in your crown, it’s crucial to contact your dentist immediately to prevent further damage.

Regular professional cleanings and dental exams will help your dentist detect any early signs of decay and address them before they become more serious. If you are unsure whether your crown is still in good condition, schedule a consultation with your dentist for a thorough evaluation.
