Can a Permanently Bonded Dental Crown Be Removed or Repaired? - Dentistry

Is it true that dentures that have already been bonded cannot be removed anymore?


Hello, doctor.
As per the subject, I would like to ask if a dental crown that has been permanently cemented can really not be removed anymore? I just had a fixed dental crown placed, but I feel like my teeth are a bit loose when I bite down, and there is a foul smell coming from inside the crown.
When I asked the dentist, they said it cannot be removed because it is permanently cemented, and they suggested it might be a problem with the tooth root.
They offered to numb the area and clean the root, but is that really the case? Is there really no way to remove it and address the issue? I paid 20,000 for a porcelain crown; how can the quality be like this? Is there really no other solution? Thank you, doctor.

Hello: If the teeth with crowns feel a bit loose, it may indicate periodontal inflammation or bone resorption.
First, periodontal treatment should be performed; if that does not resolve the issue, then consider removing the crown.

When it comes to permanently bonded dental crowns, the situation can be complex, especially if there are underlying issues such as mobility or unpleasant odors emanating from the area. The concerns you've raised about your recently placed crown are valid and warrant a thorough understanding of the options available to you.

Firstly, it is important to clarify that while dental crowns are designed to be securely bonded to the underlying tooth structure, they can indeed be removed if necessary. The term "permanently bonded" often refers to the strong adhesive used during the placement of the crown, which can make removal challenging. However, dental professionals have techniques and tools that allow them to safely detach crowns when required. This is particularly relevant in your case, where you are experiencing discomfort and suspect that there may be an issue with the tooth or the crown itself.

The fact that you are feeling movement in the crown and noticing an unpleasant odor suggests that there may be an underlying problem, such as an infection or decay at the tooth's root or surrounding gum tissue. These issues can lead to complications if not addressed promptly. If your dentist has indicated that the crown cannot be removed, it may be worth seeking a second opinion from another dental professional. They may have different insights or techniques that could help resolve your issue.

Regarding the quality of the crown, it is understandable to be concerned about the investment you made. A well-made crown, especially a porcelain one, should not cause discomfort or odor. If the crown is indeed compromised, it may need to be replaced. The presence of a foul smell could indicate that bacteria are trapped beneath the crown, which can lead to further complications such as periodontal disease or abscess formation.

If your dentist has suggested that the only option is to clean the root under local anesthesia, it is crucial to ensure that this procedure is done thoroughly. However, if the crown itself is the source of the problem, simply cleaning the root may not be sufficient. In some cases, it may be necessary to remove the crown, address the underlying issue, and then either re-cement the crown or fabricate a new one.

In terms of your options moving forward, here are some steps you can consider:
1. Seek a Second Opinion: If you feel that your current dentist is not addressing your concerns adequately, it may be beneficial to consult another dentist. They may offer a different perspective or treatment options.

2. Discuss Removal Options: Ask your dentist specifically about the possibility of removing the crown. They should be able to explain the process and any risks involved.

3. Evaluate Underlying Issues: Ensure that any underlying dental issues, such as infection or decay, are thoroughly evaluated and treated. This may involve imaging studies like X-rays to assess the health of the tooth and surrounding structures.

4. Consider Replacement: If the crown is found to be defective or improperly placed, discuss the possibility of replacing it with a new crown that fits properly and does not cause discomfort.

5. Maintain Open Communication: Keep an open line of communication with your dental provider. Express your concerns clearly and ensure that you understand the rationale behind their recommendations.

In conclusion, while a permanently bonded dental crown can be challenging to remove, it is not impossible. Your symptoms suggest that there may be an underlying issue that needs to be addressed. Seeking a second opinion and discussing your options with a dental professional can help you find a resolution that ensures your oral health and comfort.
