Upper right seventh tooth, second molar?

I would like to ask about my upper right seventh tooth, which has severe decay due to being misaligned and difficult to clean.
I underwent root canal treatment about a year ago, and now only about one-third of the tooth remains.
The dentist advised me to extract it to allow the impacted wisdom tooth behind it to erupt and fill the cavity of the seventh tooth.
I am a bit concerned about potential occlusion issues, so I opted for dental fillings and have had two sessions, but the filling has recently fallen out again.
Should I proceed with the extraction? If the wisdom tooth does not erupt properly, what should I do?

As for whether the wisdom tooth can be moved forward to replace the extracted tooth's position, it is best to consult with an orthodontist for a comprehensive evaluation.

Deciding whether to extract your upper right second molar (the 7th tooth) to allow for the growth of your wisdom tooth (the 8th tooth) is a significant decision that requires careful consideration of various factors. Based on your description, it seems that your second molar has undergone a root canal treatment and has significant decay, which has led to repeated failures in maintaining the filling. This situation raises concerns about the long-term viability of the tooth and its ability to function properly.

Understanding the Situation:
The primary reason for considering extraction is the severe decay and the fact that the tooth has already undergone a root canal treatment, which did not yield a lasting solution. If the tooth is structurally compromised and cannot be effectively restored, extraction may be the best option. Additionally, if the wisdom tooth is impacted or unable to erupt due to the position of the second molar, extracting the second molar could create the necessary space for the wisdom tooth to emerge.

Potential Benefits of Extraction:
1. Space Creation: Removing the second molar can provide the wisdom tooth with the space it needs to grow. If the wisdom tooth is healthy and positioned correctly, it may serve as a functional replacement for the second molar.

2. Reduced Risk of Infection: If the second molar is decayed and has a history of failed treatments, it poses a risk of infection, which could affect surrounding teeth and overall oral health.

3. Improved Oral Hygiene: Extracting a problematic tooth can make it easier to maintain oral hygiene, as you will have fewer teeth to clean, especially if the second molar is difficult to reach.

Concerns About Wisdom Tooth Eruption:
While extracting the second molar may facilitate the eruption of the wisdom tooth, there is no guarantee that the wisdom tooth will grow in properly or at all. Factors such as the position of the wisdom tooth, the amount of space available, and individual anatomical variations play a significant role in whether the wisdom tooth will emerge successfully.

What If the Wisdom Tooth Doesn't Erupt?
If you decide to extract the second molar and the wisdom tooth does not erupt or does not function well, you may need to consider other options:
1. Dental Implants: If the second molar is extracted and the wisdom tooth does not replace it effectively, a dental implant could be a viable option to restore function and aesthetics.

2. Orthodontic Treatment: If there are alignment issues or if the wisdom tooth is impacted, orthodontic treatment may be necessary to correct the bite and ensure proper alignment of the remaining teeth.

Consultation with Your Dentist:
Before making a decision, it is crucial to have a thorough discussion with your dentist or an oral surgeon. They can provide insights based on X-rays and clinical evaluations, helping you understand the potential outcomes of extraction versus retention of the second molar. They may also discuss the possibility of orthodontic treatment to guide the wisdom tooth into a better position if extraction is performed.

In conclusion, while extracting your upper right second molar may provide an opportunity for your wisdom tooth to emerge and potentially replace the lost function, it is essential to weigh the risks and benefits carefully. Consulting with your dental care provider will ensure that you make an informed decision that aligns with your overall oral health goals.
