Thanks for asking the query,
Your clinical history suggest that you had infection of the tooth that had spread to the periapical tissues .
Treatment of the tooth will be decided on clinical and radiological examination of the tooth. I would suggest you to visit a Dentist
and get the checkup done , take an x-ray of the tooth .
Start with antibiotic tab amoxiclav
625 mg twice tab zerodol
twice all this for five days .
Antibiotics and analgesic
will give temporary relief unless the tooth is treated you will face pain and infection.
mouthwash gargles twice daily ,
Maintain a good oral hygiene .
Hope this helps out .
