Hi, Welcome to HealthcareMagic,
Any burn or
bite injury in mouth heals very rapidly as blood supply of this area is very good. Do as follows:
1) Antiseptic mouth washes like Hexidine, 2-3 times a day
2) A good
multivitamin twice a day
3) You can also apply a pain relieving gel locally
4) Avoid spicy & hot foods/ drinks; take a nutritious diet
If it doesnot heal in few days, please see an
ENT specialist for thourough evaluation.
