Specialized Mucosa

We just learned about the Lining Mucosa.

Another part of the mouth is the Specialized Mucosa.

This is the skin on the top of the tongue that makes up the taste buds that tell you what something tastes like!

Lining Mucosa

We just learned about the Masticatory Mucosa.

Another part of the mouth is the Lining Mucosa.

This is the part of the soft loose skin inside of the mouth under the tongue, on the inside of the cheeks, and on the inside of the lips.

Masticatory Mucosa

We just learned about the Oral Mucosa.

Another part of the skin in the mouth is the Masticatory Mucosa.

This is the part of the wet mouth skin called gingiva that is on the roof of the mouth, and the top of the tongue.
The skin on these parts of the mouth is called keratinized stratified squamous epithelium.
That is a lot of big words that mean flattened skin with a lot of layers, that isn't loose and saggy.

It is different than other skin like underneath the tongue that is very loose.

Oral Mucosa

We just learned about the Gingiva.

Another part of the mouth is the Oral Mucosa.

This is a fancy way of saying the wet skin inside your mouth.
The oral mucosa is the skin on the inside of your cheeks, your gums, the skin on the roof of your mouth, on your tongue, under your tongue and the skin inside your lips.

Gingiva

We just learned about the Periodontal Ligament.

Another part of the mouth is the Gingiva, also known as the Gums.

The gums are the soft part of the inside of the mouth, around the teeth.

The lips and cheeks have skin that moves around, but the skin of the gums stays stuck to the bones of the jaw, so they help hold the teeth in place and help protect the parts of the teeth below the gums.

Gums are supposed to be a color called "coral pink" for lighter skinned people.
If the gums are red or bleeding, it can mean that the person has bad mouth problems and needs to brush more or use mouthwash.

Periodontal Ligament

We just learned about the Alveolar Process.

Another part of the mouth is the Periodontal Ligament, sometimes just called the PDL.

We learned that the tooth sits into the tooth socket bone.
The Periodontal Ligaments is a soft tissue that helps hold the tooth in place, and goes between the tooth cementum and the tooth socket.

Alveolar Process

We just learned about the Dental Alveoli.

Another part of the mouth is the Alveolar Process.

This is the jaw bone that holds on to the tooth sockets, or dental alveoli we just learned about.

Dental Alveoli

We just learned about the Amelogenesis.

Another part of the mouth is the Dental Alveoli, also known as the tooth sockets.

These are the part of the jaw that holds on to the roots of the teeth to keep them from wiggling around.

Amelogenesis

We just learned about the Tooth - Bell Stage.

Another part of a tooth growing is the Amelogenesis.

This is also called the Crown Stage or Advanced Bell Stage, and it is when the bell of the tooth starts to actually make the enamel that will be the hard outside of the tooth.

Tooth - Bell Stage

We just learned about the Tooth - Cap Stage.

Another part of a tooth growing is the Bell Stage.

The tooth buds that grew into a cap shape keep growing and make more of a bell shape.
Enamel and dentin have started to take shape, and the crown of the tooth has started to take the right shape.

Tooth - Cap stage

We just learned about the Tooth - Buds.

Another part of teeth growing is the Tooth - Cap stage.

The little buds that we already learned about keep growing and getting bigger, and they start to take a shape like a cap.
Later on these buds will turn into the hard enamel that makes up the outside of the tooth.

Kid Facts - Blast from the past: Superior Costotransverse Ligament

Tooth - Buds

We just learned about the Tooth - Initiation.

Another part of tooth development is the Tooth Buds.

The part where the teeth poke through the skin is called the dental lamina.
We already learned about the dental lamina skin getting soft in the Tooth Initiation.

After that the part of the jaw underneath the dental lamina starts to make cells that will one day turn into a tooth.
The skin starts to form a little bump for each of the 10 teeth that will be made.

These little buds are the Tooth Buds.
You can almost think of these like little seeds that will grow and some day pop out of the gums into teeth.

Tooth - Initiation

We just learned about the Dentinogenesis.

When teeth are first being developed in the gums by a baby before it is born, that is called the Initiation Stage.

Babies are usually born without any teeth showing, but their mouths have already started getting ready for teeth to be made in their jaw.

The first sign of teeth getting ready is when the skin in the mouth starts to change.
Very soon a tooth will be made underneath the skin, and the gums need to be ready to heal up quickly when a tooth pokes through the skin for the first time.

Dentinogenesis

We just learned about the Odontoblast.

Another part of a tooth growing is Dentinogenesis.

This what it is called when the Odontoblasts that we learned about create the dentin inside the teeth.

Kid Facts - Blast from the past: Intervertebral Discs

Odontoblast

We just learned about the Tooth Root.

Another part of the tooth is the Odontoblast.

These are the cells inside where the pulp is that help make the dentin part of the tooth.

Kid Facts - Blast from the past: Supraspinous Ligament

Tooth Root

We just learned about the Crown.

Another part of the tooth is the Root.

This is the part of the tooth below the gums, that has the cementum and pulp in it.

Crown

We just learned about the Pulp.

Another part of the tooth is the Crown.

This is the top part of the tooth that sticks out over the gums.

Kid Facts - Blast from the past: Costal Cartilage

Pulp

We just learned about the Cementum.

Another part of the tooth is the Pulp.

This is the inside of the tooth underneath the dentin, where the living cells are like the nerves and blood vessels.


(from: wikipedia - pulp (tooth))


Kid Facts - Blast from the past: Temporomandibular Ligament

Cementum

We just learned about the Dentin.

Another part of the tooth is Cementum.

This is a hard covering for the tooth just like the enamel that we learned about, but it is covering the part of the tooth going down below the gums, called the root.


(from: wikipedia - cementum)


Kid Facts - Blast from the past: Skull Suture Tissue

Dentin

We just learned about the Tooth Enamel.

Another part of the tooth is the Dentin.

This is the part of the tooth right under the enamel.
It is not quite as hard as the enamel, but it helps support the tooth underneath it.
