Mouth has how many teeth

This is the white, bright layer you love to show off when you smile. Enamel is a hard surface that protects all inner layers from the damage of decay and daily use.

The enamel makes your teeth healthy, as it is the strongest tissue in the body. Dentin is the second layer, or middle layer, and makes up most of each tooth. It is most similar to bone tissue and is composed of tiny tubes that connect it to the pulp of the tooth. The pulp is the third layer of each tooth, and it is comprised of blood and nerves. When you have tooth pain, this layer is why it feels so severe.

The crown is above the gum line, and the part of the tooth that lies below is the root. The root attaches to your jawbone. Teeth are a lot more complicated than they look. After teething is complete, children have 20 teeth. There are ten teeth on the bottom and ten on the top. As baby teeth begin to fall out, this is the best time for children to learn and cement healthy, lifelong oral hygiene habits so they can take care of the adult teeth that they will have after all of their teeth grow in.

Without wisdom teeth, adults have 32 teeth. There are rare cases in which some adults do not lose baby teeth. In some of these cases, you can have these teeth pulled and replaced with implants or other tooth replacement solutions, or they can be left as they are.

It will be discussed with your dentist as the situation arises, and generally, they are only pulled if the remaining baby teeth are causing you pain, discomfort, or disrupting the adult teeth around it.

Of these 32 adult teeth, there are eight incisors, four canines, eight premolars, and 12 molars. Although it is not as tough as enamel, it is also very hard. Dentin protects the innermost part of the tooth, called the pulp. The pulp is where each tooth's nerve endings and blood supply are found. When you eat hot soup, bite into a super-cold scoop of ice cream, fall and hurt a tooth, or get a cavity, it's your pulp that hurts.

The nerve endings inside the pulp send messages to the brain about what's going on "That ice cream is too cold! The pulp also contains the tooth's blood vessels, which feed the tooth and keep it alive and healthy. The pulp goes all the way down into the root of the tooth, which is under the gum. Cementum say: sih-MEN-tum makes up the root of the tooth, which is anchored to the jawbone.

You've probably noticed that you have different types of permanent teeth in your mouth. Each one has its own function. Your two front teeth and the teeth on either side of them are incisors say: in-SY-zurs. 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 food. Think back to that apple you ate: You used your incisors to crunch into the skin of the apple. The pointy teeth beside your incisors are called canine say: KAY-nine teeth.

There are four of them, two on top and two on bottom. Because these teeth are pointy and also sharp, they help tear food. Next to your canine teeth are your premolars say: PREE-mo-lurs , which are also called bicuspid teeth.

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 their shape is completely different from both incisors and canines. Premolars are bigger, stronger, and have ridges, which make them perfect for crushing and grinding food. If you open your mouth really wide, you'll see your molars say: MO-lurs. You have eight of these, four on the top and four on the bottom.

Sometimes these are called your 6-year molars and your year molars because that is around the time when they come in. 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.
