Hi. It seems as if you are having a problem with your gums. Visit a dentist
for a Clinical examination. A Clinical examination would make it clear that whether you are having problem with the gums or hard part of the tooth. Acavity could also be the cause of pain
. First visit a dentist and get it checked. If possible get an X-ray
of the tooth. For instant temporary relief take Tab. Ketorol
Dt- 2 tablets dissolved in a cup of water.
