The first thing we do every morning is brush them, and besides being essential for chewing, our teeth play an important role in the way we speak. Learn the different parts of the teeth and how they all come together to give you your unique smile with Dr. Nooshi Akavan and her team at Akavan Orthodontics in Tarzana, CA.
1. Enamel is the hardest, white outer part of the tooth. Enamel is mostly made of calcium phosphate, a rock-hard mineral.
2. Dentin is the layer underlying the enamel. Dentin is made of living cells, which secrete a hard mineral substance.
3. Pulp is the softer, living inner structure of teeth. Blood vessels and nerves run through the pulp of the teeth.
4. Cementum is a layer of connective tissue that binds the roots of the teeth firmly to the gums and jawbone.
5. Periodontal ligament is tissue that helps hold the teeth tightly against the jaw.
6. Incisors (8 total) are the middlemost four teeth on the upper and lower jaws.
7. Canines (4 total) are the pointed teeth just outside the incisors.
8. Premolars (8 total) are the teeth between the canines and molars.
9. Molars (8 total) are the flat teeth in the rear of the mouth, best at grinding food.
