when i have an issue with a tooth or my mouth, in general, I call the dentist and make an appointment to be seen. I don't wait until my 6 month hygiene appointment. That would be ludicrous. You don't have to wait until your hygiene appointment either.
As I see it, you have three choices:
1. accept that it is some gum type thing and leave it alone and let it heal. If it doesn't heal after a week or so (of not poking/prodding), call the dentist.
2. Call the dentist for an appointment and have the dentist look at it. Have him/her tell you it is X. The dentist will tell you to leave it alone and let it heal. Maybe he/she will give you an oral med to help it heal more quickly.
3. continue worrying over it, poking and prodding it causing it to bleed.. then asking for reassurance that it isn't cancer.
