Know Your Oral Cavity

Know Your Oral Cavity

Have you ever visited a dental clinic’s website then suddenly you end up searching every word on the internet? In this article, we’ll be dealing with the parts of your oral cavity or mouth to help you understand dental-related articles better.

The outer part of your mouth consists of your upper lip and lower lip. The line that demarcates your lip to skin of the face is called Vermillion border. And the groove at the middle above your upper lip is called Philtrum.

Let’s now have a look on the inside of your mouth. Children have 20 primary teeth while adults have 32 permanent teeth. Our teeth can further be subdivided into four quadrants: the upper right (URQ), upper left (ULQ), lower right (LRQ), and lower left (LLQ). Each quadrant contains 8 teeth: central incisor, lateral incisor, canine or cuspid, 2 premolars or bicuspids, and 3 molars.

Our teeth are embedded in our gums – properly called as Gingiva. Beneath the gums are bone called the Alveolar Bone. 

     

We also have tissue attachments, called Frenulum. These tissues support our lips, cheeks, and tongue. The tissue found in between your upper central incisors is called the Superior Labial Frenulum; while the one found in between the lower central incisors is called the Inferior Labial Frenulum. A Buccal Frenulum can also be seen in the gums in your cheek area. And lastly, the Lingual Frenulum is found under your tongue.

When someone looks up, you’ll see the “roof” of the mouth – called Palate. Palate is further divided into two parts: Hard Palate and Soft Palate. Hard palate is a rigid surface where tongue forces are exerted when chewing.

Palatine rugae are folds found in the hard palate. It serves an importance in forensic dentistry as this part is identical to every person like our thumbmarks.

The Soft Palate and Uvula are responsible in moving superiorly to close the nasal passages during swallowing to prevent food from entering the nasal cavity.

Zooming in our teeth and slicing it into half, we will see the different layers of a tooth. Each tooth has three layers: Enamel, Dentin, and Pulp.

Enamel is the outer hard layer of a tooth. It is white and semi-transparent.

Beneath the enamel is the dentin. Dentin is the yellowish tissue that makes up the bulk of a tooth.

And in the middle of a tooth is Pulp. Pulp contains blood vessels and nerve tissues. That is why decay should always be prevented before it goes near the pulp area.

Cementum, as seen in the photo, is an extension of enamel but covers the root part of the tooth.

To sum it up, try to remember the different parts of your oral cavity by heart to be able to understand several dental-related articles on the internet and to be able to communicate properly with your dentist. Remember the parts as much as you know your body parts.
