When food enters in mouth what do teeth do?
The teeth help you chew. And they are very helpful. If you didn't have teeth you couldn't even eat. That is how much you need teeth
bite with with their teeth then chew and then swallow and if its not in good enough information here is a even better info open there mouth put there mouth over there food close there mouth then ripp off the food with there teeth then lift there teeth up and down to chew and then swallow (making the food go down there throat)
There are four main types of teeth. Each has a slightly different shape and function. The canine teeth in the corners of your mouth help you tear food. Also called cuspids, the canines are often the largest teeth in the mouth. Incisors are the teeth in the front and center that you use to take bites of your food. The premolars and molars are used for chewing and grinding food.
There are four kinds of teeth in the mouth of a human mouth: The INCISORS are the front four teeth in your mouth and they are used for cutting your food. The CANINES are located on either side of the Incisors and are used for tearing and shredding food. The PREMOLARS are the next two teeth on both the left and right side of the canines, and they are used for grinding and crushing food…
Well, I don't know If I really understand the question but the digestion begins when the food enters the mouth, that is when teeth start crushing (mechanical), and the tongue forms the food into a ball, and salaiva covers the food and softens it, so it can go through the oesophagus. I hope I answered your question. =)
