purple spots on roof of mouth

[danks]

hello, I am 18 years old and just recently looked at the roof of my mouth and noticed two light purple spots on the hard palate extending towards the soft palate. they do not hurt and are slightly raised. also, the border around the roof of my mouth is a grayish/purple color. also, the walls of the back of my throat are purple too. i do have sever allergies but that doesnt explain the two identical purplish spots on the roof of my mouth. can someone tell me what this could be?

I get bright purple dots on the roof of my mouth in the summer from allergies.  The roof of my mouth will itch terribly when I have them.  I would try some allergy medication to see if it goes away.

Might be just pigmentation or possibly a bruise but since there wasn't any history of trauma, I would imagine its pigmentation.  I would recommend bringing it up at your next dental appointment.  In the meantime, just keep an eye on it and if it has any changes, go to your dentist.
