Gum Issues: What to Do When You Notice a Hole Near Your Wisdom Tooth - Dentistry

It feels like a piece of gum tissue has come off above the wisdom tooth?


Hello, Doctor.
This morning, I noticed a sudden hole at the junction of my last molar and the gum, as if a piece of tissue is missing, exposing something white inside (I'm not sure if it's a wisdom tooth, but it's roughly in that area).
It feels like there's a hole where the gum connects to the inside of my mouth, and the molar has become very sensitive.
I have never had my wisdom teeth removed, nor have I been checked to see if they need to be extracted.
However, I previously had a filling done on that side of the molar, and I'm unsure if that has any impact.
Therefore, I would like to ask if I need to see a dentist for an examination or if I should wait and observe for a while.
Thank you for your assistance, Doctor.

Hello: It is recommended to visit a dentist for a panoramic X-ray to confirm if there are any impacted wisdom teeth.
Additionally, if the previously filled molar is experiencing sensitivity, you may want to return to the original clinic to check if it needs to be refilled.

More Info


When you notice a hole or a cavity near your wisdom tooth, especially if it feels like a piece of tissue is missing and you can see white material underneath, it is essential to take this situation seriously. The presence of a hole in the gum tissue can indicate several potential issues, including gum disease, an abscess, or even a complication related to your wisdom tooth.

Firstly, it is crucial to understand that the area around the wisdom teeth is often prone to various dental problems. Wisdom teeth, or third molars, can become impacted, meaning they do not fully emerge from the gums due to lack of space or other dental alignment issues. This can lead to inflammation, infection, and the formation of cysts or abscesses, which may present as a hole or a soft area in the gum tissue.

The white material you are observing could be pus, which is a sign of infection, or it could be necrotic tissue. Both scenarios require prompt attention from a dental professional. If the area is sensitive, it may indicate that there is inflammation or infection present. Ignoring these symptoms can lead to more severe complications, including the spread of infection to surrounding tissues or even systemic issues.

Given your history of having a filling in the adjacent molar, it is also possible that the filling could be affecting the health of the surrounding gum tissue. Dental work can sometimes lead to changes in how the teeth and gums interact, potentially leading to gum recession or irritation.

In terms of what to do next, I strongly recommend that you schedule an appointment with your dentist as soon as possible. A thorough examination, including X-rays if necessary, will help determine the exact cause of the hole and the sensitivity in your wisdom tooth area. Your dentist will be able to assess whether the wisdom tooth needs to be extracted or if there are other treatment options available to address the gum issue.

In the meantime, maintain good oral hygiene by gently brushing your teeth and using an antiseptic mouthwash to help reduce bacteria in your mouth. Avoid any hard or crunchy foods that might aggravate the area, and if you experience pain, over-the-counter pain relievers may help alleviate discomfort temporarily.

In summary, while it may be tempting to wait and see if the issue resolves on its own, the presence of a hole in your gum tissue, especially near a wisdom tooth, is a sign that you should seek professional dental care. Early intervention can prevent more serious complications and ensure that your oral health is maintained.
