The Dental Anatomy of a Healthy Mouth

We use our teeth every day, not only to eat but also to speak throughout our daily routine. If it were not for our teeth, a number of our fundamental functions would not be possible, in fact, our teeth are the last thing that will remain of a human, which is an indicator of their importance and capacity to last a lifetime – if cared for correctly. In order to take the correct steps to maintaining a good level of oral hygiene, it is essential to understand every part of the mouth and its function. So, here is a brief anatomy of the jaw, mouth and teeth to help you find out more about this important part of the body.

Anatomy of the jaw

Most of us are aware of the different types of teeth, but do you know what they are made up from? The teeth in the human mouth consist of the incisors, canines, premolars and molars, each having a different function in the mouth. The central incisors are sharp and chisel-shaped to facilitate their function of chopping and cutting food. The lateral incisors on either side of these teeth are sharp and more pointed for tearing food. Then the canines are even further pointed and also involved in this tearing process. Our premolars are smaller versions of the molar teeth, with two cusps which crush and tear food, just as the molars do.

Below the teeth are the gingiva, or the gums, holding the teeth in place and protecting the jawbone. If the gums are not sufficiently cared for as part of your oral health routine you could suffer from gingivitis, or gum disease, which can eventually lead to the loss of teeth, creating the need for replacements such as Bicon implants. The tongue is then attached to the mouth by a membrane called the frenulum, and contains many papillae, the tiny nodules which contain the taste buds. Above this is the soft palate and hard palate.

Anatomy of a tooth

However, each tooth is made up of a similar structure below the surface that we do not see. The hard white surface we see is the enamel – this is the hardest substance in the human body, and is composed of predominantly the mineral calcium phosphate. If this surface is not brushed efficiently is may suffer a build up of decay or become stained, which is detrimental to the condition of your teeth and can be counteracted with a teeth whitening High Wycombe treatment. Beneath this is the dentine layer, which is made up of living cells which secrete hard mineral substances. At the centre of this dentine you will find the pulp cavity. This is the soft, living inner area of the tooth, inside which vessels and nerves run. Below this is the cementum, which securely attaches the roots of the teeth to the gums and jawbone, along with the periodontal ligament tissue.

Understanding how the teeth, gums and jaw work will help you to ensure you keep your oral hygiene as good as possible. If you would like any further information about dental care or your teeth please feel free to contact one of our expert dental hygienists in High Wycombe today on 01494 455900.
