Impossible to : Diagnose without an exam, xray and clinical tests to evaluate the vitality of tooth. To suggest otherwise, would be malpractice. The best thing you can do for yourself is to get the tooth evaluated asap and hear the treatment options and then decide on the treatment route you wish to undertake. Waiting will only more than likely make it worse and potentially involve neighboring teeth. Hope thi.

Possible root canal: Sensitivity to hot is usually a sign that the tooth have some type of "nerve" issue. If it is irreversible pulpitis, then root canal therapy is necessary.

Needs further eval: A slight sensitivity to hot alone is not enough to determine in a root canal is appropriate. Other factors, such a depth of a filling, pain to biting, appearance on an xray, history of unprovoked pain should all be considered. The possibility that a root canal is necessary should be considered, but seek the opinion of a dentist (or even better, an endodontist) and hear your options.

See your DDS: Heat sensitivity is a common indicator that something is wrong. Not all problems require root canal treatment. Allowing your dentist to test the effected area will enable the doctor to provide you with an accurate diagnosis.

See your endodontist: Discomfort to heat is often a sign of pulpal inflammation. If you have heat sensitivity that lingers you most likely need a root canal. A lot of times it is accompanied by lingering cold sensitivity as well. Sometimes, heat sensitivity is preceded by pain to cold, then the cold sensitivity eases up and heat pain kicks up. If discomfort is shap and short lived it may be a cavity.
