Sharp pain on release of biting force? Could be cracked tooth syndrome
Teeth with Cracked Tooth Syndrome have fractures too small to be seen on X-rays. Lower molars that absorb most of the forces of chewing, excessively clenched teeth, teeth with large fillings or teeth that have undergone root canal treatment are more susceptible to Cracked Tooth Syndrome. Treatment for this issue completely depends on the location, direction and extent of the crack.
