Hole in tooth, shock sensation on eating, severe pain. Cure for symptoms?

Hello,

Thanks for posting your query.

This pain came from a cavity that had virtually reached the root. you have to visit dentist for root canal treatment if there is no other cause i.e. fracture.

Till then you can apply tea tree oil and a clean medicine dropper. With care, put 3-4 drops of the oil onto the affected tooth/teeth and leave it for at least 30 minutes. Tea tree oil has very good healing and antibacterial properties which would help alleviate the pain and kill the bacteria.

You only need about 6-8 tablespoons of salt and about a cup of water. Just wait for the salt to completely dissolve before you gargle the solution for about 1-2 minutes. Repeating the process a few times may be necessary to make the pain subside significantly.

Regards.

cavities in teeth can exist for years before they present with symptoms like pain or sensitivity, so it hasn't occurred overnite . biting was the stimulus required which brought the problem in the open.
for time being eat ultracet and get yourself to a dentist's visit asap. he/she will take an xray and estimate the depth of the cavity and probably suggest you for a root canal and later capping of the teeth.
take care
