Longmont Family Dentist Discusses the Parts of the Tooth and How to Avoid Cavities

Many patients think of their teeth as solid, stable, and somewhat lifeless. However, teeth are actually comprised of multiple, interconnecting layers, which together allow the tooth to develop and grow. Maintaining the health of this complex system is the primary goal of dentists and health-conscious patients alike. Today I’m going to review how dental cavities affect the health of your teeth. By understanding the structure your smile, you’ll be able to actively prevent and recognize potentially harmful dental problems.

When most patients think of teeth, they think of them as hard, smooth, and white. However, they are actually only thinking of the white and solid enamel layer. The outer layer of the tooth—dental enamel—is responsible for allowing us to chew and speak easily. Enamel protects the other layers of the tooth, allowing teeth to withstand a significant amount of wear, tear, and stress.

Below the enamel is the dentin layer. Dentin is porous and strong. However, it is often darker or yellower in color than enamel.  Dentin is the middle layer between the enamel and the inner core of the tooth.

The hollow space within the tooth is filled with dental pulp. Dental pulp is soft and malleable because it is an amalgamation of nerves, tissue, and blood vessels. Enamel and dentin protect the pulp from external substances. Patients with substantial decay may find that they have exposed dental pulp. Unprotected nerves are incredibly painful and they make it difficult to eat and drink normally. When a patient experiences severe decay and infection our Longmont general dentists may need to perform a root canal to remove all of the infected pulp from inside the tooth.

Plaque and tartar compromise the structure, integrity, and health of teeth—putting teeth at risk for cavities and infections. Both plaque and tartar are acidic, and acid demineralizes teeth, causing them to develop cracks and holes. Plaque is a mixture of bacteria and sugars that accumulates on teeth throughout the day. Brushing and flossing twice a day can help minimize plaque buildup. However, it is impossible to cleanse teeth of all plaque. Aging plaque can calcify on teeth as tartar (also called calculus). Only a dental professional can remove tartar from dental enamel.

Once significant amounts of enamel, dentin or pulp are lost, teeth are not able to regenerate these layers naturally. At-home daily hygienic maintenance coupled with professional dental scaling and polishing is the most effective way to deter cavity development. Both types of care are necessary to enjoy a strong, beautiful smile for many years.
