Thanks for asking the query,
Tooth pain indicates infection of the tooth involving the pulpal tissue, such type of tooth need to be root canal
treated to save it permanently.
I would suggest you to visit a Dentist
and get the checkup done, take an x-ray of the tooth.
In this process the canals are removed , cleaned and sealed.
Meanwhile you start with tab amoxiclav 625 mg tab aceclofenac
serratiopeptidaes twice for 3-5 days.
Use antiseptic mouthwash gargles twice daily, maintain a good oral hygiene
Hope this helps out.
