Thanks for asking the query,
Tooth pain indicated infection in the tooth that is involving the pulpal tissues, such type of infected tooth need to be root canal
treated to save it permanently.
I would suggest you to visit the Dentist
get the checkup done, take an x-ray of the tooth.
Start with the course of antibiotics and analgesics.
Maintain a good oral hygiene
use antiseptic mouthwash gargles.
Hope this helps out.
