Hello and thank you for your question:
The little red blotches you notice on the roof of your mouth could possibly be broken capillaries (the little blood vessels in your tissue) due to the extraction. We use retractors to keep your tongue out of the way and to protect your throat from inhaling (aspirating) the tooth. This is a common trauma seen after third molar extractions. The bump on the roof of your mouth could be a growth.
-Lymphoid aggregates are a common finding in that area treatment is not required and they are benign.
They are common findings of the Waldeyer's Ring.
-Torus Palantinus: an outgrowth of bone also benign, although rare to extend that far back
-Fordyce Granules are sebbaceous glands (sweat glands in the mouth) and are a nomral finding
-
Nicotine Stomatitis if you smoke this can also cause the red blotches
-
Erythroplasia is a malignancy that needs to be taken out
These are a few lesions found near the
uvula. Unfortunately, I cannot diagnose you without proper evaluation and
biopsy. But rest assured at your age and location of lesion, it is most likely a benign issue that either needs to be monitored or taken out with a small window of healing.
Best wishes and health, I hope this gives you peace of mind.
Dr. Ward
