What’s the anatomy of a tooth? A tooth consists of two main structures: Crown. This is the part of your tooth that you can see — the portion above your gums. Enamel — a hard, protective substance — covers your tooth crown. Root. This is the part of your tooth that holds it in your jaw. You can’t see the root because your gums cover it.
This article covers the anatomy of the tooth, including structure, parts, types, functions, and clinical aspects. Learn more about this topic at Kenhub!
There are four main types of teeth in humans, shown labelled here. Dental anatomy is dedicated to the study of tooth structure. The development, appearance, and classification of teeth fall within its field of study, though dental occlusion, or contact between teeth, does not.
We’ll go over the anatomy of a tooth and the function of each part. We’ll also go over some common conditions that can affect your teeth, and we’ll list common symptoms to watch for.
Tooth, any of the hard, resistant structures occurring on the jaws and in or around the mouth and pharynx areas of vertebrates. Teeth are used for catching and masticating food, for defense, and for other specialized purposes. Learn more about teeth in this article.
Dental anatomy is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. (The function of teeth as they contact one another falls elsewhere, under dental occlusion.)
Read the following article to find out more details about the two types of human teeth. Teeth anatomy Tooth structure The four groups of teeth are not identical, but they all share a typical and general tooth anatomy, as follows: Crown; Pulp chamber; Neck of tooth; Dental root; Root canal
There are five teeth in each quadrant, composed of two incisors (central and lateral), a canine, and two molars. These teeth are referred to as letters A, B, C, D and E. The primary teeth begin to erupt at 6 months of age. The permanent dentition is composed of 32 teeth with 16 in each arch.
Teeth are hard, mineral-rich structures which are used to chew food. They are not made of bone like the rest of the skeleton, but have their own unique structure to enable them to break down food. Tooth enamel is the most mineralized tissue in the body, consisting mainly of the rock-hard mineral hydroxyapatite.
The anatomy of a tooth divides into two main sections: the crown and the root. The crown of the tooth is what is visible in the oral cavity, and the root of the tooth is embedded into the bony ridge of the upper and lower jaws called the alveolar process via attachment to the periodontal ligament.
