White Bumps in the Mouth: Causes and Treatments

White spots protruding in the oral cavity?

Hello Doctor, for the past month, I have noticed a bubble-like growth with a white spot at the site of my extracted lower left wisdom tooth.
Initially, it started as a small bump and then grew larger within a few hours (during this time, I experienced mild soreness).
It would then burst and heal on its own, only to repeat this cycle for about two weeks.
Seven days ago, I noticed that the bump had swollen again, but it was not large or painful, and it did not continue to swell for the past week.
I quickly went to see a dentist, who said it didn’t look like anything serious and might be an infection (but I read that infections usually heal within about two weeks).
I asked the dentist if it could be due to the fact that my upper left wisdom tooth has not been extracted, causing unintentional friction.
The dentist replied that it was possible.
I decided to have the upper left wisdom tooth extracted, and now three days have passed, but there are no signs of improvement with the small white bump on the lower left.
I am unsure what to do next.
The dentist mentioned that if the symptoms do not improve, I could return to have the bump removed.
Is it really that simple? I’ve read online that it could be a precursor to gum cancer or oral cancer, and it’s really frightening.

Dear Ms.
Yu,
Hello! As mentioned, it may be necessary to take an X-ray to check for any issues with the bones.
If there are any problems, debridement may be required, and then it should heal.
A thorough clinical examination is still essential.
Please take care of yourself! Wishing you peace and smooth recovery!
Sincerely,
Dr.

More Info

Understanding white bumps in the mouth can be concerning, especially when they persist or change in appearance. Based on your description, it seems you have been experiencing a recurring issue with a white bump near the area where your wisdom tooth was extracted. This condition can be attributed to several factors, including infections, irritation, or even benign growths.
Firstly, the appearance of a white bump that resembles a blister and is associated with pain can often indicate a few common oral conditions. One possibility is an oral mucosal cyst, which can occur due to blocked salivary glands or irritation from adjacent teeth. Another possibility is a recurrent aphthous ulcer (canker sore), which can appear white or yellowish and is often painful. These ulcers can be triggered by stress, hormonal changes, or certain food sensitivities.

In your case, the fact that the bump initially grew, burst, and then healed only to reappear suggests a cycle of irritation or infection. The dentist's assessment that it does not appear to be a malignancy is reassuring, but it is essential to monitor the situation closely. Oral cancers can present as persistent sores or lumps, but they typically do not resolve and reappear in the same manner as you described.
The connection between your upper wisdom tooth and the lower bump is also noteworthy. If the upper tooth was causing friction or irritation to the lower gum, it could lead to localized inflammation or infection. After the extraction of the upper wisdom tooth, it is reasonable to expect some improvement in the irritation of the lower area, but it may take time for the tissue to heal completely.

If the white bump persists beyond a few weeks or shows signs of worsening, such as increased size, pain, or changes in color, it would be prudent to follow up with your dentist or an oral surgeon. They may recommend a biopsy or further imaging to rule out any serious conditions.
In terms of treatment and prevention, maintaining good oral hygiene is crucial. This includes regular brushing and flossing, using an antibacterial mouthwash, and avoiding irritants such as spicy or acidic foods that can exacerbate the condition. If you are experiencing significant discomfort, over-the-counter pain relief or topical anesthetics may provide temporary relief.

In summary, while the symptoms you describe can be alarming, they are often associated with benign conditions. However, it is essential to remain vigilant and consult with your healthcare provider if symptoms persist or worsen. Regular dental check-ups and open communication with your dentist about any changes in your oral health are key to ensuring any potential issues are addressed promptly.
