Should I Get a Dental Implant After My Tooth Repair Cracked? - Dentistry

Share to:

If a filled tooth has a portion of the dental cement cracked and missing a corner, is it necessary to get a crown?


Hello, Doctor.
I would like to ask about the issue of getting a dental prosthesis.
I previously had a molar that was filled, but it cracked after biting down on something too hard.
The part that is missing is the portion that was filled with dental cement.
Today, I went to see the dentist, and after reviewing the X-ray, the dentist informed me that my tooth has already undergone root canal treatment.
The filling occupies about half of the original tooth structure, meaning that half of my tooth is essentially made of cement.
The dentist recommended that I get a dental prosthesis because even if I were to have it refilled, it could crack again in the future.
However, I noticed that a full porcelain prosthesis starts at around $12,000, which is quite a sum.
I would like to ask, if I choose not to get a prosthesis and instead opt for refilling the tooth, could this lead to more severe damage to the tooth, potentially requiring an implant in the future? Or, if I take good care of the refilled tooth, is it possible that I won't need a prosthesis?

Hello, Xiao Qiu: If you have already undergone a root canal treatment and the tooth itself is significantly damaged, even if it is restored, it is still prone to fracture.
It is advisable to consult a dentist to evaluate the possibility of placing a crown for protection.

When it comes to dental health, especially after a tooth has undergone significant repair and is showing signs of cracking, the decision to get a dental implant or pursue further repair can be quite complex. Based on your situation, where a previously filled molar has cracked and is largely composed of filling material, there are several factors to consider.

Firstly, it’s important to understand the implications of your tooth’s condition. Since your tooth has undergone root canal treatment, it means that the nerve and blood supply have been removed. This often leads to a reduction in the tooth's structural integrity, making it more susceptible to fractures. When a tooth is primarily filled with material, as in your case, it lacks the natural strength that a healthy tooth would have. The fact that your dentist has indicated that the tooth is already compromised and suggests a dental implant is a strong indication that the tooth may not be able to withstand normal chewing forces for much longer.

If you choose to repair the tooth again, there are risks involved. While it may seem like a less expensive option initially, the reality is that repeated repairs can lead to further weakening of the tooth structure. Each time a tooth is filled, especially one that has already undergone significant repair, there is a risk of additional cracks or fractures occurring. If the tooth were to fail completely, you might find yourself in a situation where extraction is necessary, leading to the need for a dental implant anyway. This could ultimately result in higher costs and more invasive procedures.

On the other hand, opting for a dental implant, while initially more expensive, can provide a more permanent solution. Dental implants are designed to mimic the function of natural teeth and can last many years, often a lifetime, with proper care. They also help maintain the integrity of the jawbone, which can be compromised when teeth are lost. The investment in an implant can save you from the potential complications and costs associated with repeated repairs and the eventual need for extraction.

In terms of costs, while the upfront expense of a dental implant may seem daunting, it’s essential to consider the long-term benefits. Many dental insurance plans offer some coverage for implants, and financing options may also be available through your dental office. Additionally, the cost of repeated fillings and potential future procedures can add up, making the implant a more economical choice in the long run.

If you decide to pursue the repair option, it’s crucial to maintain excellent oral hygiene and follow your dentist’s recommendations closely. Regular check-ups will be essential to monitor the condition of the tooth and catch any further issues early on. However, be prepared for the possibility that this tooth may not hold up over time.

In conclusion, while the decision ultimately rests with you, it is advisable to weigh the risks and benefits of both options carefully. A dental implant may represent a more reliable and long-term solution, especially given the current state of your tooth. Consulting with your dentist about your concerns and discussing the potential for financing or insurance coverage can also help you make a more informed decision. Remember, investing in your dental health now can prevent more significant issues and expenses in the future.
