Hey there... U should visit a nearby dentist for a proper diagnosis so that treatment can be planned accordingly... Take care..!!

Hi..if enamel of the tooth is broken then inner pulp will get exposed leading to increased sensitivity or pain. Visit dentist as you might need a root canal treatment. In the meantime use any desensitizing paste. Regards

From your description it appears that you're tooth is decayed. That is, it has a cavity. Possibly, a part of your tooth was weakened due to the decay and on biting something hard, it broke off. The pain on cold sensation is a typical sign of sensitivity. Visit your dentist who will check the tooth and maybe take an xray and then decide whether a simple filling is enough to fix the problem or a root canal will be necessary.

This pain looks typical of pulp pain ..due to the stone crushing the tooth could have got fractured and every time u eat the fragments separate giving pain..cold food increases the pain..kindly visit your dentist who will examine and determine future course of action

Rice Stone crushing might hv chipped off a part of ur tooth n even more would hv caused propogation of major n minor cracks on ur teeth which could n extended from ur enamel into ur dentin causing sensitivity towards coldbreeze too. Get examined by a dentist to assess the extent of damage n gt treated accordingly which may vary from a filling to a cap. Meanwhile apply a desensitizing toothpaste such as senquelF or sensodyne liberally onto that tooth deface n rince off after 5 mins. Repeat as many times reqd .regards

Hiiii....the tooth fragment might have got fractured or it might have had cavity already. In both cases, the tooth becomes sensitive to cold food. It indiactes that the nerve of the tooth has been hurt and had become sensitive. Consult your dentist , u might need a root canal treatment to be done!! Take care
