What does a white spot behind the upper back tooth mean?

Hello,

Welcome to icliniq.com.

It does seem to be the starting of a simple mouth ulcer (attachment removed to protect patient identity) or just some white normal epithelial changes. Usually, such changes come when our diet does not contain good leafy vegetables and grains causing a lack of vitamin B complex or it can occur even during monthly hormonal changes. It is nothing to be worried about. Such changes will go away in 14 days as we improve our diet. Does the white spot cause some irritation or pain while eating spicy foods or just by touching it with the tongue?

I hope this helps.

Thank you.

Hello,

Welcome back to icliniq.com.

It can be seen (attachment removed to protect patient identity) and is not some ulcer. It seems to be just some epithelial changes. It can be due to some previous injury like while pulling out of a wisdom tooth or a previous ulcer that has healed. It is not a cause for worry. It will either remain like this or will go away soon as new blood vessels form in the area. Hope you do not have much of a smoking problem. Do you think it has formed just now or just noticed it now? You can just watch it for one or two months for any changes, which will not be there surely, just for your assurance, and then just forget about it.

I hope this helps.

Thank you.
