from what you have written,it suggests a tooth decay....Please get it checked with your dentist....In case of an enamel or dentinal caries,you can get it restored using simple filling procedures....but if it gets too deep and involves pulp tissue inside,u might need an rct...so,please visit your dentist asap to fix the issue before it worsens. ...hope it helps

It is unfortunate that you are having this problem. The symptoms are suggestive of tooth decay. Kindly visit your dentist to get it checked and you may need some fillings. Hope this helps.
