What could cause a white spot inside the mouth?

Hello,

Welcome to icliniq.com.

As I understand you have two concerns:

The uvula hanging low is not uncommon, as the anatomy of individuals vary. However, you have not mentioned about any specific complaints which you may face with an abnormal uvula. Has the uvula always hanged low as you describe, or is it a recent observation? Are you facing any issues with speech or swallowing food? If it is affecting your function and daily routine, there are options of corrective surgeries to reduce the length and the bulk of the uvula. However, if your speech and swallowing function is not impaired and it does not irritate your throat, it is prudent to not undergo any surgical intervention.

About the white spot, I would like to know if you have any habits with respect to cigarette smoking or tobacco consumption. White spots may be harmless, or maybe a sign of fresh injury by adjacent teeth or could be sign of something more serious. If you do not have any habits, I would suggest you keep the spot under close observation and look for changes or increase if any.

If you do have a smoking habit, it is wise to get the spot checked by an oral and maxillofacial surgeon who may perform a biopsy if deemed necessary.

Hope I have clarified your query.

Thank you.
