Grey spot on my gum next to a tooth?

Question

It's about the .7mm in diameter and it has made this area sensitive. The earliest I can see my dentist is in 3 weeks. Any suggestions to what it is?

Answer 1

Here is a site you can try---Medical.JustAnswer.com----you can also do a search for {doctors online UK} doctor sites in England are more likely to give internet info because they dont get sued all the time like US doctors do.
