Otherwise how did you lose your sense of smell?
If your dog is okay, then give he/she food because maybe they think it is food. Or the other option to to pay more attention because dogs might do that for more attention (play with them more)

Relax... Your mouth does not have the vasculature that would allow you to bleed out. By this time some healing should have formed but it would still be a raw wound.

Your mouth if anything should be fine.
