Image: I have a painless, small, white dot on my gums.  What could it be?

Hi doctor,

I have a small white dot on my gums. It looks like a whitehead. I noticed it a couple of days ago. It is painless. It is just above my left canine. I do not know what it is. It is towards the top of the gum. I have attached the photo.

Can you suggest what it could be? I am scared of the dentist, so any option avoiding that would be nice.

Welcome to icliniq.com.

It looks like a minor aphthous ulcer, which gives no pain and subsides by itself. Please check if there is any pus discharge, pain in the tooth and any other area of the mouth also has this kind of spots. Aphthous ulcer often causes minimal symptoms or problems.

Oral ulcers are small round or ovoid ulcers of 2 - 4 mm in diameter. They are round or ovoid in most situations but are often more linear in common site. They have an ulcer floor that is initially yellowish white and surrounded by an erythematous halo or redness.

They are found mainly on the mobile mucosa of the lips, cheeks, the floor of the mouth, sulci or below the tongue. Yours is in between the junction of gums and sulcus of the cheek, so it is a soft mucosa looks like to be. They occur in groups of only a few ulcers that is, one to six at a time. In your case, you have one only.

They heal in 7 to 10 days, and they may recur at intervals of one to four months. They leave little or no evidence of scarring. If it pains, then you can apply pain relieving gel. If it does not subside in a week or 10 days, then do visit your dentist.

Differential diagnosis:

Aphthous ulcer.
