Temporary Solutions for Tooth Decay While Awaiting Dental Implants - Dentistry

Temporarily unable to get a dental filling and worried about continued decay of the tooth root?


Several months ago, my upper right incisor's temporary crown fell off.
After reviewing the CT scan, the dentist informed me that the tooth root was decayed to the point that even the temporary crown secured by a dental post could not be held in place, and I would need a dental implant.
Due to financial constraints, I have not proceeded with the implant.
Recently, I have occasionally felt some sensitivity in the tooth root, which made me realize that the decay issue is ongoing (I had root canal treatment when the temporary crown was placed, so I didn't notice the problem sooner).

I would like to ask Dr.
Lin: After I undergo root canal treatment again, can I request the treating dentist to temporarily seal the large cavity on the outside of the tooth root with a filling material or something else to prevent further decay? Would this affect my ability to get an implant in the future? If so, are there any other temporary solutions available? Thank you for your guidance on these questions!

Hello: The method you mentioned in the second paragraph refers to root-end filling surgery combined with periodontal bone regeneration surgery.
However, it is essential to consider the condition of the affected tooth and the surrounding destruction.
After a thorough evaluation of the success rate, the surgery can be performed.
It is advisable to have further discussions with the treating physician.
Additionally, this surgery may include out-of-pocket expenses, so it is necessary to assess your financial situation.
Sincerely, Lin Chia-Yung, Department of Dentistry, Taichung Hospital, Ministry of Health and Welfare.

When dealing with tooth decay, especially in the context of a tooth that has already undergone root canal treatment and is now experiencing further decay, it is crucial to approach the situation with care and an understanding of the potential implications for future dental procedures, such as dental implants.

Given your situation, where your temporary crown has fallen off and the underlying tooth root is decaying, it is understandable that you are seeking temporary solutions while you await the financial means to pursue a dental implant. The first step in addressing this issue is to consult with your dentist about the possibility of performing a root canal retreatment. This procedure can help to remove any remaining infected tissue and clean out the decay from the tooth root.

Once the root canal retreatment is completed, your dentist may be able to seal the outer cavity of the tooth with a temporary filling material. This can help protect the tooth from further decay and prevent bacteria from entering the tooth structure. However, it is essential to understand that this is a temporary solution. The longevity of such a filling will depend on various factors, including your oral hygiene practices, dietary habits, and the extent of the decay.

Regarding your concern about whether sealing the cavity will affect your ability to receive a dental implant in the future, the answer is generally no. As long as the tooth is properly treated and the surrounding bone structure remains healthy, you should still be a candidate for an implant later on. However, if the decay progresses significantly or if the tooth becomes non-restorable, extraction may become necessary, which could complicate the implant process.

In addition to the temporary filling, there are other measures you can take to manage your dental health until you are ready for an implant. Here are some recommendations:
1. Maintain Excellent Oral Hygiene: Brush your teeth at least twice a day and floss daily to keep the area around the affected tooth clean. This will help minimize the risk of further decay.

2. Avoid Sugary Foods and Drinks: Sugar can exacerbate tooth decay, so try to limit your intake of sugary snacks and beverages.

3. Use Antimicrobial Mouthwash: An antimicrobial mouthwash can help reduce bacteria in your mouth and may assist in preventing further decay.

4. Regular Dental Check-ups: Even if you are not ready for an implant, regular visits to your dentist can help monitor the condition of your tooth and surrounding structures. Your dentist can provide professional cleanings and check for any signs of worsening decay.

5. Consider Temporary Dentures: If the situation with your tooth becomes untenable, you might want to discuss the option of a temporary denture to fill the gap until you can afford an implant.

6. Discuss Financial Options: Many dental offices offer payment plans or financing options for procedures like implants. It may be worth discussing these options with your dentist to find a solution that fits your budget.

In conclusion, while it is possible to temporarily seal the cavity after a root canal retreatment, it is essential to remain vigilant about your oral health and to plan for the eventual replacement of the tooth with an implant. Regular communication with your dentist will be key in navigating this process effectively.
