Managing Tooth Decay: Options for Your Second Molar Before Wisdom Tooth Extraction

Fill the second molar?

Hello: My second molar has had a root canal treatment, and it is very close to my impacted wisdom tooth.
I need to have the wisdom tooth extracted before I can get a dental crown.
However, I have an exam in July, and I don't want to have the wisdom tooth removed during this time because it can be painful.
Currently, my second molar is hollow and only filled with a medicated paste.
If I want to restore it, can the dentist use a temporary filling material? (Previously, I asked other dentists, and they advised against it because saliva could cause the temporary filling to dislodge, making it ineffective.) If I don't get it filled, can my tooth last until July before having the wisdom tooth extracted?

If the molar has undergone root canal treatment the next day, even though the wisdom tooth has not been extracted and a crown has not yet been placed, it can still be filled with resin.
This provides better sealing.
However, before getting the crown, it is advisable to avoid biting down on hard foods, but it is still recommended to get the crown done as soon as possible.

More Info

Managing tooth decay, especially in the context of a second molar that has undergone root canal treatment and is in close proximity to a wisdom tooth, requires careful consideration of several factors. Your situation is quite common, and it’s understandable to want to avoid additional discomfort, especially with an upcoming exam in July.

Options for Managing Your Second Molar
1. Temporary Filling with Medicinal Paste: Since your second molar is currently filled with a medicinal paste, this is a temporary solution that can help manage any discomfort and protect the tooth from further decay. However, this is not a long-term solution. The effectiveness of this paste will depend on the extent of the decay and the condition of the tooth. If the paste is holding up well and you are not experiencing significant pain, it may be possible to wait until after your exam to address the tooth more permanently.

2. Consideration of Tree Resin Fillings: You mentioned the possibility of using tree resin (likely referring to a natural resin composite) as a filling material. While some natural materials can be used in dentistry, they may not provide the same durability and sealing properties as traditional dental materials. If previous dentists have advised against using such materials due to concerns about moisture and potential displacement, it would be wise to heed that advice. Moisture can indeed compromise the integrity of many filling materials, leading to failure and the need for further treatment.

3. Wisdom Tooth Extraction Timing: If your wisdom tooth is impacted (or "阻生齒"), it is often recommended to extract it to prevent complications such as infection or further decay of adjacent teeth. However, if you are concerned about the pain and recovery time associated with extraction, it may be feasible to postpone the extraction until after your exam, provided that your second molar can remain stable during this period.

Risks of Delaying Treatment
While it may be tempting to delay treatment until after your exam, there are risks involved. If the decay in your second molar worsens, it could lead to more severe pain, infection, or even the need for more extensive dental work, such as extraction. Additionally, if the wisdom tooth is causing pressure on the second molar, it could exacerbate the situation.

Recommendations
- Consult with Your Dentist: It’s crucial to have a detailed discussion with your dentist about your options. They can assess the current state of your second molar and provide tailored advice based on your specific situation.

- Monitor Symptoms: Keep an eye on any changes in your tooth’s condition. If you experience increased pain, swelling, or other symptoms, it may necessitate earlier intervention.

- Plan for Extraction: If you decide to wait until after your exam, make sure to schedule the wisdom tooth extraction as soon as possible afterward to prevent further complications.

In conclusion, while it may be possible to manage your second molar temporarily until after your exam, it is essential to weigh the risks and consult with your dentist to ensure that you are making the best decision for your dental health. Taking proactive steps now can help prevent more significant issues down the line.
