Thanx for the replies.

As for the more obvious spot, it turned out to be a blood blister. It is now gone.

As for the other 2, the dentist believes they are amalgam tatoos. They are near an area where I had extensive crown lenthening surgery along with a crown.

I will make it a point to get an x-ray to make for sure. That will have to wait until I return home after May 18- I am in the Air Force and currently "on the road".

Once I return home, I will also make an appointment with a throat doc to see what's going on in my neck.

I will keep you updated so we can all learn from my situation.

Thank you & God Bless.
