Immediately consult a dentist in ur area

Plz visit ur dentist and u need to get RCT done with the tooth,as cavity has gone beyond the living part of the tooth called pulp or nerve and now there is a localized collection of pus around the roots extending into ur gums.

These kind of symptoms appear when the treatment is delayed for a very long time. The tooth requires root canal treatment so that the symptoms can be alleviated permanently and extraction of the tooth can be avoided. Please do not depend upon medications for this as they only provide temporary symptomatic relief. Search for a dentist in your vicinity using Practo and try to schedule an appointment as soon as possible. Regards.

Hello, Very high probability that you might have developed an abscess.You might require an RCT treatment to drain the infection and save the tooth.
