SMART Notebook 8.1Dec 10 - 23:22Let's Look at Our TeethDec 10 - 23:22The teeth in the centre of the front of your mouth that are easiest to see are called incisors. There are four on the top and four on bottom. Incisors are shaped like tiny chisels, with flat ends that are somewhat sharp. These teeth are used for cutting and chopping foodDec 10 - 23:46Think about what happens when youbite and apple. You bite in first with your incisors to break the skin of the apple. The pointy teeth on either side of your incisors are called canine teeth. There are four canine teeth in total in your mouth, two on top and two on bottom. Because these teeth are pointy and also sharp, they help tear food.Dec 11 - 21:12Next to your canine teeth are your premolars. You have eight premolars in all, four on top and four on the bottom. You'll need to open a bit wider to see these teeth, but when you do, you'll notice that they have a completely different shape than both incisors and canines. That's because premolars are bigger, stronger, and have ridges -all of which make them perfect forcrushing and grinding food. (A good way to feel the ridges is to run your tongue along the top of these teeth.) Dec 11 - 21:13Finally, open really wide, and you'll see your molars. You have eight of these guys, with four on the top and four on the bottom. Molars are the toughest of the bunch: they are even wider and stronger than premolars, and they have more ridges.Molars work closely with your tongue to help you swallow food: the tongue sweeps chewed-up food to the back of your mouth, where the molars grind it until it's mashed up and ready to be swallowed.gumsbottommolarsDec 11 - 21:27 Wisdom teeth aren't used for anything and may not make you smarter, but some people believe that they may have been used by people millions of years ago to help them chew food. When children get older, they often get four more molars all the way in the back of the mouth, one in each corner. This usually happens around age 20, and the teeth are called wisdom teeth.

Without teeth, it wouldn't be possible - try to say the word without letting your tongue near your teeth, and see what happens! Now say "face," and notice how your teeth hit your lower lip to make the "f" sound and how your upper and lower teeth close quickly to produce the soft "c" sound. We need our teeth and lips to help us form sounds and say letters. Try saying the word "tooth" slowly and feel how your tongue first hits the inside of your incisors to produce the hard "t" sound and then goes in between your upper and lower teeth to make the "th" sound.Dec 10 - 23:48Animals have different teeth because they eat different food.Animals that eat vegetables are calledHumans eat both meat and vegetables and we are calledomnivorescarnivoresherbivoresAnimals that eat meat are calledCan you put the answers in the right place?AnswersDec 10 - 23:54
