Toothache is not always related to caries or inflammation of the nerve - even he althy teeth can hurt us. Among the most common causes of such pain are colds and heart diseases.

In this case, the pain is felt not in one tooth, but on the entire surface of the upper jaw.
6 supposedly harmless symptoms we ignore
On the plane. The toothache that occurs in a person on an airplane as soon as he gains altitude is known as aerodentalgia. The cause of this pain is a sharp drop in atmospheric pressure - under its influence, the air gaps present in the mouth, under fillings and bridges expand.
