Unexpected Oral Growth: What Could It Be?

There is a growth in the mouth?

I just finished eating and suddenly noticed something in my mouth.
It's located between the upper and lower teeth towards the back.
It feels a bit sensitive when pressed, but I don't feel it unless I touch it.
However, there is a persistent sensation of a foreign object.

The above situation may be caused by frictional irritation of the buccal mucosa during chewing, leading to an inflammatory response of the mucosa.
It is recommended to consult a dentist for further examination.

More Info

Unexpected oral growths can be concerning, especially when they appear suddenly and cause discomfort or an unusual sensation. Based on your description, it sounds like you may be experiencing a few potential conditions that could explain the growth you’ve noticed in your mouth.

1. Mucosal Cyst or Mucocele: One common cause of sudden oral growths is a mucocele, which is a fluid-filled cyst that can occur when a salivary gland duct is blocked or damaged. These are usually painless but can cause a feeling of pressure or discomfort, especially if they are located near the teeth or gums. Mucoceles can often resolve on their own, but if they persist or cause significant discomfort, a dental professional may need to evaluate them.

2. Fibroma: Another possibility is a fibroma, which is a benign tumor made up of connective tissue. These can develop in response to irritation or trauma in the mouth, such as from biting the inside of your cheek or from dental appliances. Fibromas are usually firm and painless, but they can cause a sensation of fullness or pressure.

3. Dental Abscess: If the growth is associated with pain or swelling, it could be a dental abscess, which is a localized collection of pus due to infection. This typically occurs at the root of a tooth or in the surrounding gum tissue. An abscess may require treatment, including drainage and antibiotics, to resolve the infection.

4. Eruption Cyst: If you are still in the age range where wisdom teeth or other teeth are erupting, an eruption cyst could form over an erupting tooth. This is a fluid-filled sac that can create a sensation of pressure and may be visible in the area where the tooth is trying to emerge.

5. Other Growths: There are other less common conditions, such as papillomas (small wart-like growths) or even more serious conditions like tumors. However, these are less likely if the growth appeared suddenly and is not associated with significant pain or other systemic symptoms.

Given the location you described (between the upper and lower teeth at the back), it is crucial to consult with a dental professional who can perform a thorough examination. They may take X-rays or perform other diagnostic tests to determine the exact nature of the growth. It is essential to address any oral growths, especially if they cause discomfort or change in sensation, to rule out any serious conditions and to receive appropriate treatment.

In summary, while there are several benign explanations for the sudden appearance of a growth in your mouth, it is always best to seek professional advice. A dentist or oral surgeon can provide a definitive diagnosis and recommend the best course of action based on your specific situation. Remember, early intervention can often lead to better outcomes, so don’t hesitate to reach out for help.
