Why Do My Teeth Hurt When I Bite Down?

Be it mild or severe; tooth pain is unbearable. This can be due to several reasons. First, an exposed dentil due to enamel erosion may lead to exposed nerve endings. This causes teeth sensitivity, hurting your teeth when you bite down. Enamel erosion can take place due to several factors, including teeth grinding. 

Tooth pain can also occur due to gum diseases or infections. Brushing your teeth can make the teeth roots exposed and cause pain. This pain can also be due to your wisdom teeth. Wisdom teeth may cause pain while penetrating through gums. Stuck food debris may lead to infection and resultant pain in your teeth.

Cavities: Cavities occur due to bacterial action, producing acids and making grooves or cavities in your teeth. It’s your tooth that comes into play while biting down, and a cavity or crack in your teeth may cause pain in your teeth. More pain symbolizes greater damage.

Apart from these factors, tooth pain can also occur due to headaches, damaged tissues or nerves connecting your jaw to the skull, or due to infected sinuses.

What To Do Now?

Unlike other body pains, which go away with time, you cannot ignore tooth pain. Teeth come into action every time you eat, and if you feel pain while eating or biting anything, it is advised to consult your doctor. He will find out the root cause behind the pain and will give you medications and recommendations. 

He may recommend you have some testing and a detailed examination of your teeth health. This may involve an X-ray or other test. This will help your doctor know the exact cause, and with proper medicines, you can recover over time. Your doctor can also suggest surgery whenever needed.
