with my tongue, can i see a doctor? before my tooth became sore and wiggly i got this scratch on the inside of my mouth down really low where i would imagine the root would be to the tooth that now hurts. does it sound like i have an infection? as in the scratch would have gotten infected and then spread through my root up to my tooth? my dentist is hard to get an appointment with. if i went to the doctor could they give me some antibiotics?

also, if i don't go in and continue using hydrogen peroxide on the area, might it heal by itself?
