Linda - I sure do hope it's nothing but getting it checked is a good thing to do. That way, if it's nothing serious, you can quit worrying and if it is something, then you can start doing something about it.

It is very important to get the right kind of Oral Cancer screening. Not all dentists are familiar with how it should be done. When I asked my dentist if he did exams for Oral Cancer, he quickly replied "Oh yes! every time a patient comes in!" Well, I looked at the OCF main page where it says "Dental Issues" and the description there did not match at all what my dentist did during the exam. So I printed out everything on how to do it from the OCF page, including a section just for dentists and gave it to him. The next time I went in, he did do everything right!. Here is the link on "How to know if you've had a good oral cancer examination":
