The hard substance that makes up the bulk of a tooth is called dentin. Dentin is a dense, bony tissue that is similar in composition to bone but is harder. It surrounds the pulp of the tooth and is covered by enamel on the outside.

Dentin is made up of microscopic tubules that contain nerve fibers, which is why when dentin is exposed due to decay or damage, it can cause sensitivity or pain. Dentin is crucial for protecting the delicate pulp of the tooth and providing support for the enamel.

If you are experiencing tooth sensitivity or pain, it could be due to exposed dentin. It is important to visit your dentist to address any issues with your teeth and prevent further damage.

Proper oral hygiene, including regular brushing and flossing, can help maintain the health of your dentin and prevent issues such as tooth decay and sensitivity. It is also important to visit your dentist for regular check-ups and cleanings to ensure that your teeth and gums are in good condition.

Remember, dentin is a vital component of your teeth and plays a crucial role in maintaining their health and function. By taking care of your teeth and practicing good oral hygiene, you can keep your dentin strong and protect your teeth for years to come.
