yes it does. It starts right when you put the food in your mouth and the mouth is part of the oral cavity.
Oral Cavity
The carbohydrate digestion polymer in the oral cavity is starch. Salivary amylase, an enzyme in the saliva, starts breaking down starch into smaller sugar molecules like maltose.
The oral cavity contains the teeth and tongue. It is the opening through which food enters the body and where the process of digestion begins.
The digestive system begins with the oral cavity. This is where the process of mechanical and chemical digestion starts as food is broken down by chewing and enzymes in saliva.
The oropharynx is the space behind the oral cavity and above the laryngopharynx.
The oral cavity is less formally known as the mouth. It's primary function is to bite, chew, and swallow food. It is also involved in speaking and can be used for breathing.The oral cavity as its name indicates its a cavity = space, the most important function of it is that it provides space for mechanical digestion of food. Providing saliva for easier digestion, bears a tongue which helps us in moving food and tasting it.Mechanical (chewing) and chemical (Starch digestion by amylase) digestion of food.So this is what I got from my physiology book:The mouth receives food and begins digestion by mechanically reducing the size of solid particles and mixing them with saliva. The lining of the mouth as well as the saliva glands provide lubrication which aide in speech, swallowing, and the digestion of food.

The oral cavity is another name for the mouth.
The eight cutting teeth located in the front part of the oral cavity are known as incisors. These teeth are responsible for cutting and biting food into smaller pieces for easier chewing and digestion.
Salivary amylase aids in digestion of polysaccharides. Remember that digestion actually begins with chewing (mastication), which can be distinguished as mechanical and not chemical digestion. The salivary glands of the oral cavity secrete saliva (hence the name). 98% is water and 2% is electrolytes, mucus, glycoproteins, enzymes, and other compounds such as the antibody IgA (immunoglobin A). Mucus, lysozyme, and IgA aid in immune response.
The mouth breaks down food mechanically, provides enzymes in saliva that start the process of carbohydrate digestion, and moistens food. In addition, taste buds give information about the quality of the food.
The parotid duct empties into the oral cavity at the level of the second upper molar. It carries saliva from the parotid salivary gland located near the ear to the mouth, where it helps with digestion and lubrication of food.
