Life is unimaginable without the pearly whites we call teeth. They look remarkably strong, like white marble stone, but have you ever wondered what they are made of? Enamel, dentin, pulp, crown, root, and periodontal ligament are part of your tooth’s anatomy. They come together layer by layer to provide the durability and strength your teeth require.
Three Layers of Teeth
Our teeth contain 3 main layers, which are:
The enamel is what makes your teeth pearly white. It is the hardest part of your teeth. It is responsible for handling your everyday biting and chewing tasks. Calcium and phosphate form the enamel. Therefore, to enhance the strength of your enamel, you need to consume a diet enriched with these properties.
Healthy enamel promises the bright and confident smile you need. Furthermore, you must avoid sugary snacks and drinks that unleash an army of damaging bacteria to attack your tooth enamel.
The dentin is sandwiched between enamel and pulp. It protects the pulp by surrounding it and supports the enamel. Dentin, not only enamel, is also thicker and denser than bone. It is usually yellow. That’s why when you brush too hard, your dentin starts peeking through the enamel, and your teeth look yellow. Its exposure causes heightened sensitivity.
The pulp is the most tender part that contains tiny blood vessels and nerves. The strength of your dentin depends on the pulp, as it provides the right nutrients. If a cavity becomes severe and breaks through the dentin, reaching the pulp, this indicates an advanced stage of decay where either a root canal or extraction can save your tooth.
Which Layers of the Teeth Are Sensitive and Which Are Not
As you keep going inside the dental layers, sensitivity increases. The innermost layers of your tooth are more sensitive and vulnerable. The most insensitive part of your tooth is enamel. It does not contain any nerves but acts as a cover.
When bacteria bypasses enamel, it penetrates dentin. It makes the most of your tooth structure. Dentin can be exposed due to gum recession or extreme enamel erosion. It can feel discomfort due to the pressure and high temperatures.
- Highly Sensitive
The purpose of all the outer layers is to protect the pulp. This part contains all the functionality, including nerves and blood vessels. If bacteria succeed in attacking the pulp, your whole tooth becomes compromised. Dental problems such as infections, injuries, and cavities are the causes of pulp invasion.
Regular dental checkups from an experienced family dentist like Dr. Ravinder Kunwar at Smiles Forever Dentistry are the best way to keep all tooth layers healthy.
