What are the 5 surfaces of a tooth?

The crown of each tooth has 5 surfaces, as follows:

• Buccal (facing the cheek or lip)
• Lingual (facing the tongue)
• Mesial (between the teeth)
• Distal (between the teeth)
• Chewing (occlusal for molars and premolars, incisal for incisors and canines)

What are the 6 surfaces of a tooth?

Incisal – The biting edge of an anterior tooth. Lingual – The surface that faces the tongue. Mesial – The surface that is closest to the midline of the face. Occlusal – The chewing surface of posterior teeth.

What is a tooth surface code?

The code letter refers to different parts or surfaces of the tooth. For example, “M” stands for mesial (the front surface of the tooth). “D” stands for distal (the back surface). An “O,” which stands for occlusal, is the top surface of a back tooth.

What are the surfaces of an anterior tooth?

The system involves numbering the labial/buccal surfaces as 1, the mesial surfaces as 2, the lingual surfaces as 3, the distal surfaces as 4, and the occlusal surfaces as 5. Anterior teeth therefore have surfaces numbered 1 to 4, and posterior teeth have surfaces numbered 1 to 5 (Fig.

What is mesial and distal?

Mesial and distal — These are the sides that come into contact with adjacent teeth. The mesial side faces the front of the mouth. The distal side faces the back of the mouth. Cusps — The parts of the occlusal surface that are raised.

Is tooth 11 anterior or posterior?

The upper teeth are numbered from 1-16 from right to left and the lower teeth are numbered 17-32 from left to right. Therefore, 1,16,17 and 32 would refer to your wisdom teeth and 6-11 and 22-26 would be your anterior teeth in the upper and lower jaws respectively. Similarly, 6,11 22, 27 would be the canines and so on.

What is axial surface of tooth?

ax·i·al surfaces surfaces of a tooth parallel to its long axis; the axial surfaces are the vestibular (labial or buccal), lingual, and contact (mesial or distal).

What does it mean when a dentist says buckle?

Buccal – the outer surface of the tooth that faces the cheek.

What is the surface of the tooth towards the midline called?

mesial – Surface of the tooth facing toward the midline of the face.

What is the junction of two tooth surfaces?

An angle is the junction of two or more surfaces of a tooth. A line angle is that angle formed by the junction of two surfaces of a tooth crown along an imaginary line.

How many surfaces does a tooth have?

Each tooth has 5 tooth surfaces. Depending on whether the tooth is in the front or back, the surfaces are as follows: mesial, distal, lingual, facial or buccal, and incisal or occlusal. The fee for fillings is determined by how many surfaces of the tooth are involved.

What are the 5 surfaces of the anterior teeth?

In all, there are five surfaces of the tooth where a filling can be placed: the distal, occlusal, buccal, mesial, and lingual/palatal surfaces. Additionally, teeth are segmented into two major categories: anterior, and posterior.

What is the proximal tooth surface?

proximal surface ( proximate surface) the area where the mesial surface of one tooth touches the distal surface of another; called also contact area or surface. vestibular surface the surface of a tooth that is directed outward toward the vestibule of the mouth, opposite to the lingual surface; see also buccal surface and labial surface.

Should teeth feel smooth?

That’s how they should feel every time you brush your own teeth. Use your tongue to feel at the gum line, and see if the tooth surfaces feel smooth and slick throughout your mouth. Try the upper front teeth first, which is where most people do the best job because it’s easiest to reach.
