Tooth sensitivity is a result of exposed dentin. Dentin is the layer under the tooth’s enamel that has microscopic tubules filled with nerve endings. While the enamel protects the dentin in the crown, cementum protects the dentin that reaches beneath the crown to the roots.
The Four Tissues That Make up a Tooth Are:
Enamel—a hard tissue coating the crown. It is the hardest tissue in the body. Once it is fully formed, it can’t grow or repair itself, but can remineralize. This means it can regain lost minerals. To remineralize your teeth, you will want to get your intake of calcium, phosphorous and vitamin D.
Dentin—the main part of a tooth. Dentin is harder than bone and softer than enamel, and it contains microscopic canals, or tubules. These canals transmit pain stimuli and nutrition through the tissues. Dentin also gives the tooth its color.
Cementum—covers the root of the tooth, and is a thin layer. It is harder than bone but softer than enamel and dentin.
Pulp—the soft tissue in a tooth’s center surrounded by dentin. It is made of blood vessels, lymph vessels, nerve tissue, connective tissue and cells. It nourishes the tooth and repairs dentin.
Risks for Tooth Sensitivity:
–Are you brushing your teeth with a hard-bristled toothbrush and brushing in a harsh sawing motion?
–Are you eating and drinking highly acidic products?
–Do you have worn, leaky fillings in your teeth, or broken teeth, exposing the dentin?
–Do you have gums that are receding (pulling away from the gums)?
–Do you grind your teeth while you sleep?
–Have you recently had dental work done, such as fillings, whitening, or a crown done?
–Do you have a buildup of plaque on your teeth?
Don’t let tooth sensitivity stop you from enjoying life. Things you can do to help with tooth sensitivity include brushing with a soft-bristled toothbrush, limiting acidic foods, using a densensitizing toothpaste and wearing a mouth guard if you grind your teeth while you sleep.
