The dental implant cannot be removed?


Hello, Doctor! I had my front tooth crown redone about four years ago.
The dentist mentioned that the initial root canal treatment was incomplete, so the dental post needed to be removed.
However, the post could not be removed because the dentist was concerned it might break the original tooth, so we decided against it.
A full porcelain crown was placed, but I can still faintly see the metal color of the post inside, which bothers me.
I would like to ask if the dental post is indeed impossible to remove in such cases? I am considering having the crown redone, but I am worried that the post might be stuck again.
I hope to receive your advice.
Thank you!

Hello: There are several types of materials for all-ceramic crowns.
You can choose a more opaque material for the inner crown to mask the color of the metal post.
However, if the metal pigmentation has extended to the tooth root or even overflowed to the gums, the only solution would be to remove the metal post.
It is recommended to visit a larger medical facility to utilize a microscope along with other instruments for the removal of the metal post.
Thank you!

When it comes to dental posts, particularly in the context of dentures or crowns, the question of whether they can be removed is quite nuanced. Dental posts are typically used to provide support for crowns or bridges, especially after a root canal treatment. They are cemented into the tooth structure, and their removal can be complicated, depending on various factors.

In your case, it sounds like the dental post was left in place due to concerns about damaging the remaining tooth structure. This is a common scenario in dentistry. If a post is deeply embedded and the surrounding tooth structure is compromised, attempting to remove it can lead to fractures or further damage to the tooth. This is why your dentist opted not to proceed with the removal.

If you are considering replacing your crown due to the visibility of the metal post, there are a few options to explore:
1. Crown Replacement: If the current crown is not aesthetically pleasing due to the visibility of the metal post, you might consider replacing it with a new crown that has a more aesthetic material, such as a porcelain-fused-to-metal or an all-ceramic crown. These materials can provide a more natural appearance and may help mask the metal underneath.

2. Post Removal: While it is technically possible to remove a dental post, it is not always advisable. If the post is deeply seated and the tooth structure is fragile, the risks may outweigh the benefits. If removal is necessary, a specialist, such as an endodontist or oral surgeon, may be better equipped to handle the procedure safely.

3. Alternative Solutions: If the post cannot be removed and you are still unhappy with the appearance, you might discuss other options with your dentist. This could include the use of a veneer or a different type of restoration that can cover the existing crown and post without needing to remove them.

4. Consultation with a Specialist: If you are concerned about the post and its impact on your dental health and aesthetics, consider seeking a second opinion from a prosthodontist. They specialize in restoring and replacing teeth and can provide insights into the best course of action for your specific situation.

5. Long-term Considerations: It's essential to weigh the long-term implications of any dental work. If the post is stable and the tooth is functioning well, it may be worth keeping it in place, especially if the risks of removal are significant.

In summary, while dental posts can sometimes be removed, it is not always a straightforward process and can involve risks. If you are considering replacing your crown, discuss your concerns with your dentist, who can help you explore the best options for achieving the aesthetic results you desire while maintaining the health of your tooth. Regular follow-ups and open communication with your dental care provider are crucial in managing your dental health effectively.
