What are the 7 tooth surfaces?

Any competent dental service should be able to tell you the seven tooth surfaces are the occlusal, lingual, facial, distal, mesial, proximal and, incisal surfaces especially dental services in Brooklyn, known for their expertise.

All of these surfaces play a specific role in the function or appearance or both, of teeth.

What is the Anatomy of a Tooth

When trying to understand the seven tooth surfaces, it’s helpful to first have a basic understanding of the anatomy of a tooth:

  • The crown, represents the noticeable part of the tooth which typically sits above the gum line and is covered by a hard protective layer of enamel.
  • The root, embedded in the jawbone it’s covered by a smooth tissue called cementum.
  • The dentin, lies below the enamel and cementum, hard and bony it’s what gives teeth their yellowish tint.
  • The pulp, powerhouse of the tooth of some sort can be found at the core storing nerves and blood vessels.

As mentioned above, there are several different tooth surfaces that play a crucial role in the understanding oral hygiene.

I. Occlusal Surface

Located in an area typically used for chewing and biting, it is the top surface of a tooth more precisely, on the molar and premolars playing an essential role in the grinding and food crushing process.

II. Lingual Surface

Located on the inner side of the teeth and facing the tongue, the lingual surface plays an important role when it comes to speech and tongue movements, helping you shape the sounds you make.

III. Facial Surface

Often the face first noticed when looking at someone’s mouth and teeth, it’s a surface that is apparant when a person smiles or speaks. On the front sides of the teeth it plays a keep role in the aesthetics of someone’s teeth and is therefore important to keep clean and healthy.

IV. Distal Surface

Found on the exterior part of the teeth, the distal face is the furthest away from the midline of the mouth. Playing a major role in proper teeth alignment, the distal surfaces is on the opposite side of the mouth from the mesial surface.

V. Mesial Surface

Placed closest to the midline of your mouth, the mesial surface is found on the back teeth and just like the distal surface, this surface also plays a crucial role in proper teeth alignment.

VI. Proximal Surface

Found between the mesial and distal surfaces on the back teeth this surface goes hand in hand with the ones mentioned previously in the part they play in having well aligned teeth.

VII. Incisal Surface

At the top of the incisors, this surface represents the biting face of the front teeth, it therefore has an important role when it comes to biting and cutting food often being the first surface to come into contact with food.

Proper dental care plays a significant role in the prevention of tooth decay and dental problems and through regular maintenance, individuals can help keep their seven tooth surfaces healthy and free from decay or damage.
