Hello,
I can understand your concern. A burned incisive papilla, however bad it has been been burn, should not take up to 3 months to heal. What I suspect here is your front teeth have been damaged due to excessive heat as the coffee must have come in contact with the teeth, too.
Our teeth also have blood supply as with any other organ in the body. Excessive heat or
injury can damage the
nerve and blood vessels supplying the tooth that we cannot see from the outside. Once damaged, the blood supply cannot be regained and the tooth has to go through
root canal treatment to eliminate infection and pain you are experiencing. The swelling in the papilla might be due to
cyst formation at the end of the root of the front teeth.
I would advise you to visit your
dentist and got for x-ray of the front teeth along with electric pulp vitality test (EPT). If the teeth are in fact non-vital, you will have to go through root canal treatment. If the teeth are fine regarding its blood and nerve supply, then the dentist can see the incisive papilla region and can advise you regarding that.
I hope this information helps you. Thank you for choosing HealthcareMagic. I wish you feel better soon.
Best,
Dr. Viraj Shah
