Most of the time, when you look at someone’s bright smile, you are only seeing the outer layer of their teeth—called the enamel. However, there are several other layers that each play an important role. The following guide explores their purposes, what damage they may sustain, and how to enhance your oral care routine in light of your new knowledge. 

Enamel

The most visible part of the tooth, enamel consists primarily of minerals and is responsible for guarding against decay.

Enamel may erode when a person consumes a lot of sugary or highly acidic foods and drinks, such as soda and acidic fruits. These substances interact with oral bacteria and create lactic acid, a common source of erosion.

Limit your consumption of these substances and brush your teeth thoroughly after you do consume them. You should also avoid hard foods like hard candy and ice cubes, which can crack enamel.

Dentin 

Located immediately beneath the enamel, dentin consists primarily of the mineral hydroxyapatite. Its yellow shade comes through once enamel starts wearing away.

Aggressive brushing and gum disease can lead to receding gums, which expose the dentin layer and cause sensitivity to hot and cold substances. Prevent dentin exposure by brushing and flossing properly and avoiding sugary, acidic foods.

Pulp

The pulp is the soft area inside the tooth’s center that features the tooth’s nerves, blood vessels, and connective tissue. It’s responsible for producing dentin.

In addition, the pulp’s blood vessels maintain blood flow to keep the tooth moisturized and nourished. Tooth decay and injury can lead to pulpitis, an inflammation of the pulp that can cause it to die. Pulpitis can also lead to a tooth abscess that can cause serious infection.

Circumvent these issues by maintaining an effective oral care routine and avoiding tooth injury as much as possible. 

Root

As the lower two-thirds of a tooth, the root anchors the tooth in position. It’s covered with a layer of bone but can become exposed due to gum disease, aggressive brushing, smoking, misaligned teeth, or tooth grinding.

An exposed root causes sensitivity and can lead to more severe cases of gum disease, so use a soft-bristled toothbrush, avoid tobacco, and seek treatment for misaligned teeth or tooth grinding.
