MOUTH – THE GATEWAY INTO THE BODY

Overview:

The mouth is the largest opening into the human body, it comprises the lips, teeth, gum, alveolar bone, mucosal, Salivary glands, tongue etc. Almost all the materials that enter the body go through the mouth.

However, the mouth, or oral cavity, is an oval-shaped opening in the lower part of the face. It begins at the lips and stops at the throat. It is crucial to numerous body functions; like breathing, speaking, chewing, swallowing, expressing affection and digesting food. It is also useful for manipulation and defence.

Furthermore, the mouth is part of the digestive system. The mouth enables air, food water and medication to pass into the stomach. The inner lining of the mouth is called the mucosa.

Moreover, in a healthful mouth, the tissues should be moist, pink in colour, odour-free and pain-free. Tooth brushing twice daily, flossing once daily and visiting a dentist every 6 months help to keep the mouth healthy.
