Get tooth ache when i exercise. is this normal?

No: Many times as the pulp of a tooth is dying a slow death (an irreversible pulpitis) it will begin to throb. When the pulse rate and blood pressure increase during exercise, this can be a prelude to more regular and intense discomfort in the future. See your dentist or an endodontist.

Nope: It's a sign something might be amiss. Better to have it examined and treated while the problem is minor. If you wait, the treatment may become more extensive. Call a local dentist for an appointment.

It is not normal: See your dentist for evaluation and x-ray to rule out dental or gum problem. Good luck.
