Teeth hurt due to a number of potential causes, including tooth decay, gum disease, and tooth sensitivity. But teeth hurt from external damage, too. Cracked tooth syndrome makes teeth hurt when you bite down on a cracked or fractured tooth. (1), (2)
Why Do My Teeth Hurt? The Start of Cracked Tooth Syndrome
Cracked tooth syndrome starts with the development of cracks in the teeth that are too small to appear on a dental x-ray. The cracks can occur from chronic teeth grinding (bruxism) or from tooth or jaw alignment that puts a disproportionate amount of pressure on a certain tooth or teeth. Cracked teeth syndrome usually makes the molars or back teeth hurt, because they do most of the work of chewing. If you have cracked tooth syndrome, you may only notice that your teeth hurt when you bite down in a certain way, in contrast to the more frequent tooth pain associated with a tooth abscess or a cavity.

Teeth Hurt from Cracked Tooth Syndrome
Your dental professional can use special tools to test your teeth for possible cracks. Treatment usually involves a tooth crown for mild cases, but if the tooth crack impacts the tooth pulp, a root canal may be necessary. If the tooth crack penetrates down to the jaw, the tooth will need to be removed. (2)
