Should You Extract Both Wisdom Teeth and a Cavity Tooth?

Is it necessary to extract all of them?

Hello! I had a root canal treatment on my upper left second molar, but it has decayed again before I could get a crown.
I also have a horizontally impacted wisdom tooth that can only be seen on an X-ray.
The issue is that some doctors recommend extracting both wisdom teeth, while others say it's sufficient to remove just one.
This has left me uncertain about what to do next.

Dear Miss Hsiao-Ting,
Hello! If the horizontal wisdom tooth is located beneath the root of the second molar, it may not need to be extracted, as this would require more bone disruption.
Please communicate more with your dentist.
Thank you! Wishing you safety!
Sincerely,
Dr.

When faced with the dilemma of whether to extract both wisdom teeth and a tooth with a cavity, it's essential to consider several factors, including the condition of the teeth, the potential for future complications, and your overall dental health.

Firstly, let's address the tooth that has undergone root canal treatment and is now experiencing decay. This situation is not uncommon, especially if the tooth has not yet been restored with a crown. A tooth that has had a root canal can still be susceptible to decay, particularly if the sealing of the canal was not optimal or if there are cracks in the tooth structure. If the decay is extensive, your dentist may recommend extracting this tooth, especially if it is deemed non-restorable.
Now, regarding the wisdom teeth, particularly the horizontal one, there are a few considerations. Wisdom teeth, or third molars, can often become problematic due to their position in the mouth. If they are impacted (meaning they are unable to fully erupt through the gums), they can lead to complications such as infection, damage to adjacent teeth, or even cyst formation. If your horizontal wisdom tooth is causing issues or is likely to cause issues in the future, extraction may be warranted.

The recommendation to extract both wisdom teeth versus just one often depends on the specific circumstances of your dental health. If both wisdom teeth are impacted or if there is a risk of future complications from one or both, it may be advisable to remove both at the same time. This approach can prevent the need for multiple surgeries and can be more efficient in terms of recovery.

However, if the second wisdom tooth is healthy and not causing any issues, your dentist may suggest leaving it in place. The decision can also be influenced by your comfort level, the potential for complications, and the advice of your dental care team.

In summary, it is crucial to have a thorough examination, including X-rays, to assess the condition of both the cavity tooth and the wisdom teeth. Discussing your concerns with your dentist will help clarify the best course of action. If you are uncertain about the recommendations you have received, seeking a second opinion from another dental professional can provide additional insights and help you make an informed decision.

In addition to these considerations, maintaining good oral hygiene is vital, especially in the context of existing dental issues. Regular brushing, flossing, and dental check-ups can help manage decay and prevent further complications. If you are experiencing difficulty cleaning certain areas, such as around the wisdom teeth, your dentist may recommend specific tools or techniques to improve your oral hygiene routine.

Ultimately, the decision to extract teeth should be made collaboratively with your dental care provider, taking into account your unique dental situation, the potential risks and benefits, and your personal preferences.
