Wisdom Tooth

We just learned about the Maxillary Second Molar.

The next tooth back in the mouth is the Wisdom Toothor Third Molar.

This tooth is a molar just like the first and second molars.
Many times there is not enough room in a person's mouth for these teeth, so a dentist or orthodontist will pull the teeth out.

If these teeth stay in the mouth, they can push up against the other teeth and hurt them.
Sometimes the gums in the mouth can get swollen or bruised by these teeth.

Maxillary Second Molar

We just learned about the Maxillary First Molar.

Another tooth is the Maxillary Second Molar.

These ones are just like the Maxillary First Molars, just further back on the jaw.
They have 4 cusps, and they work to help grind up the food.

Some people get another row of teeth behind these, but for other people these are the last teeth in the mouth.

Maxillary First Molar

We just learned about the Maxillary Second Premolar.

Another tooth in the human mouth is the Maxillary First Molar.

These teeth have cusps or pointy parts on them like the bicuspids, but they have four points instead of the two of a bicuspid.
There are two cusps on the cheek side, and two on the tongue side.
Sometimes people have a fifth cusp called the Cusp of Carabelli.

Molars are used for grinding up food that is in the mouth.

There are primary or baby teeth molars, but those are replaced by premolars.
The adult molars show up further back in the jaw after the mouth gets big enough to have space for them.

Maxillary Second Premolar

We just learned about the Maxillary - First Premolar.

The next teeth in the mouth are the Maxillary Second Premolars.

These also have two "cusps" on them like the First Premolars, so they are also bicuspids.
They are not as pointy as the First Premolars, so they are used more for grinding up food than tearing it up.

Just like the First Premolars, there are no baby or primary premolars.
The Second Premolars come up in the place where the baby molars were at when they fall out.

Maxillary First Premolar

We just learned about the Maxillary Canine.

Another tooth in the mouth is the Maxillary First Premolar, also sometimes called the bicuspids.

Just like the canine teeth had one "cusp" on them, these teeth have two cusps, which is why they are sometimes called bicuspids.

These teeth are used to help grind up the food in your mouth, but they also have sharp pointed ends so they can be used to bite down into food and help tear it up.

For baby or primary teeth, there are no premolars, only incisors, canines and molars.
When the first baby molar tooth comes out, the first premolar comes up in it's place.

Maxillary Canine

We just learned about the Maxillary Lateral Incisor.

Another tooth is the Maxillary Canine, also sometimes called the cuspid.

These are the teeth right next to the front four incisors.
Remember starting from the middle, there are two of each type of teeth:
Central Incisors
Maxillary Lateral Incisors

The Maxillary Canines are a little different than the incisors, because they have a "cusp" on them, meaning they have pointed ends, almost like a dog's tooth.
That's really why they are called "canine" teeth, because canine is another word for a dog, and it you look in a dog's mouth you will see some very sharp pointy teeth!
It's also why sometimes they are called the "cuspid" teeth, because they have a cusp on them.

The canines are like a tooth that can work as an incisor to cut and tear food, but also like the bigger teeth that help you grind up and chew your food once it's in your mouth.

The canine is the longest tooth in the mouth.

Maxillary Lateral Incisor

We just learned about the Central Incisors.

The next set of teeth that show up in your mouth are the Maxillary Lateral Incisor.

These are right next to the two front teeth, one on either side.
Just like the central incisors they are used for cutting and biting things.

Central Incisors

We just learned about the Baby Teeth.

Usually the first baby teeth that people get are the Central Incisors.

Most babies start with two front bottom teeth, and then later the two front top teeth come in.
These incisors are made to be sharp and bite through things like carrots.

Baby Teeth

We just started learned about human teeth!

Humans are usually born with no teeth, and around six months after they are born the teeth start to pop out!
We call these first teeth Baby Teeth, and they are also known as milk teeth, temporary teeth, primary teeth or deciduous teeth.

There are twenty baby teeth that come in, with ten on top and ten on bottom.
They usually start with the bottom middle ones, then the top middle and then next on the bottom and top until all twenty are in.

The baby teeth are very important, because they help keep the jaw strong and in the right place, and they are holding a place for the bigger adult teeth that come in later.

Let's keep learning about the Human Mouth.

Probably the most important part of your mouth is your Teeth.

An adult human can have up to 32 teeth, that's a lot of chompers!

People grow two sets of teeth, 20 baby teeth, and then those fall out and we get the grown up teeth.

Human Mouth

We just learned about the Interphalangeal Ligaments.

We've learned a lot about the Connective Tissue that holds all of our bones and muscles together!

Another part of the human body is the Mouth.

We might not think about it much, but there is a lot going on in the mouth.
We use it to eat, drink and breathe, and we also use it to make words when we talk, or make sounds like whistles clicking or snapping with our lips and tongue.

From our teeth, to our lips and tongue, there are a lot of things to take care of in our mouths, and the professional person we go to see that takes care of our mouth is usually a dentist.

There are also orthodontists who work on moving teeth around, periodontists who work on the bones supporting the teeth, endodontists who specialize on the inside of the tooth, prosthodontists who work on building replacement teeth, and oral and maxillofacial surgeons who work on the areas around the jaw.
