What Causes Teeth to Hurt?



Cracked teeth due to trauma are a well-known cause of severe toothaches. The exposed dentin is highly sensitive to heat and cold due to the high concentration of nerves.

Key takeaways:

Tooth pain is typicaly caused by cavities, holes that form on the enamel layer of teeth.

The exposed dentin will register pain upon pressure or contact with hot and cold substances. Bacteria will enter through cavities, causing inflammation and infection in the cavity.

Gum disease caused by bacteria is yet another cause of tooth pain. Receding gums will expose the teeth roots, causing severe pain.

Nerves in the cavity will scream with every sip of hot coffee, every bite of cold ice cream, and will often require a root canal, which scoops out the inflamed pulp and replaces it with a rubbery material, according to the American Association of Endodontics (AAE).
