Q & A

How many types of teeth do humans have and what are they called?

Humans have four types of teeth: incisors, canines, premolars, and molars. Incisors are the front teeth used for biting, canines are the sharp teeth used for tearing, premolars and molars are used for chewing.

At what age do babies typically get their first teeth?

Babies typically get their first teeth at 6 months old.

How many baby teeth do children have and when do they usually get all of them?

Children have 20 baby teeth, which are also known as primary teeth, and they usually have all 20 by the time they are 3 years old.

What happens to primary teeth around the age of 6?

Around the age of 6, primary teeth start to get loose as bigger, stronger permanent teeth begin to push them out.

By what age do most people have all of their adult teeth?

By the age of 12 or 13, most people will have all 28 of their adult teeth.

How many wisdom teeth do humans have and when do they typically appear?

Humans have four wisdom teeth, which typically appear by the age of 21.

Why might someone need to have their wisdom teeth removed?

Wisdom teeth might be removed because they can cause discomfort or problems due to their size and position, and they are not necessary for chewing.

What is the function of the enamel on teeth?

The enamel on teeth is the hard, outer layer that protects the teeth and gives them their bright, white appearance if maintained properly through brushing.

What is the role of cementum in the mouth?

Cementum covers the roots of the teeth and helps anchor them to the jawbone, preventing the teeth from falling out.

What is the pulp inside the tooth and what does it do?

The pulp inside the tooth contains nerves and blood vessels. It sends pain messages to the brain when the tooth experiences extreme temperatures or damage.

Why is it important to brush and floss regularly as mentioned in the script?

Brushing and flossing regularly is important to remove food particles and plaque, which can lead to cavities and gum disease if not properly managed.

🦷 'How the Body Works': All About Teeth

The script introduces a segment from KidsHealth titled 'How the Body Works,' featuring a musical performance by Chloe and the Nurb. The song educates about the importance of teeth, their types, and their functions. It explains that babies get their first teeth at 6 months and have 20 primary teeth by age 3. These are replaced by 28 permanent teeth by ages 12 or 13, with wisdom teeth potentially coming in by age 21. The song emphasizes the need for dental hygiene, suggesting brushing and flossing to maintain teeth health. It also touches on the different types of teeth, such as incisors, canines, premolars, and molars, and their roles in biting, tearing, and chewing food. Additionally, it mentions the structure of teeth, including the crown, roots, enamel, dentin, pulp, and cementum, and the importance of these components for a healthy mouth.

Keywords

💡Kidney

The kidney is an essential organ in the human body that plays a crucial role in filtering waste products from the blood and maintaining electrolyte balance. In the video, the Foggy Liver Boys sing about the importance of having a kidney or two, emphasizing their vital function in the body. This keyword is introduced humorously to engage the audience and highlight the significance of kidneys in maintaining overall health.

💡Teeth

Teeth are hard, calcified structures found in the mouth that are used for biting, chewing, and grinding food. The video script highlights the importance of teeth in various aspects of life, such as speaking, chewing, and singing. It also mentions the different types of teeth and their functions, making it a central concept in the educational content of the video.

💡Baby Teeth

Baby teeth, also known as primary teeth, are the first set of teeth that emerge in infants, usually starting at around 6 months old. The script mentions that babies have 20 baby teeth, which are essential for their early development. These teeth eventually fall out and are replaced by permanent teeth, illustrating the natural process of dental growth and development.

💡Permanent Teeth

Permanent teeth are the second and final set of teeth that humans develop, starting to emerge around the age of 6 when primary teeth begin to fall out. The video script explains that by the age of 12 or 13, one typically has all 28 permanent teeth, which are meant to last a lifetime. This keyword is important in the video as it discusses the transition from baby teeth to the more robust and long-lasting permanent teeth.

💡Wisdom Teeth

Wisdom teeth are the third molars that typically emerge in late adolescence or early adulthood, around the age of 21. The video script humorously notes that by this age, one will probably have four wisdom teeth, two on the top and two on the bottom. Wisdom teeth are often discussed in the context of dental health because they can sometimes cause discomfort or require extraction due to their late emergence and potential impact on other teeth.

💡Incisors

Incisors are the front teeth, both on the upper and lower jaws, that are used for biting and cutting food. The script mentions that there are four incisors on the top and four on the bottom, playing a key role in the initial processing of food in the mouth. This keyword is important for understanding the different functions of teeth and how they work together for effective digestion.

💡Canines

Canines, also known as cuspids or eye teeth, are the pointed teeth located on either side of the incisors. The video script describes canines as 'spiky teeth' that help tear tough food, with two on the top and two on the bottom. Canines are essential for tearing and are a critical component of the human dentition.

💡Premolars and Molars

Premolars and molars are the teeth located at the back of the mouth, responsible for the grinding and crushing of food. The script explains that these teeth are essential for the final stages of breaking down food before swallowing. They are an integral part of the digestive process and are highlighted in the video to emphasize their role in eating and nutrition.

💡Dentin

Dentin is the calcified tissue that forms the bulk of the tooth structure beneath the enamel. The video script mentions that the pulp's nerves send pain messages through the dentin, which is a critical component in sensing temperature changes in food and drink. Understanding dentin's role is important for comprehending the sensitivity and functionality of teeth.

💡Cavity

A cavity is a hole in the tooth that forms as a result of tooth decay, caused by acid from plaque eroding the enamel. The video script warns about cavities and emphasizes the importance of brushing and flossing to prevent them. This keyword is crucial for discussing dental hygiene and the consequences of poor oral care.

💡Gum

Gums, also known as gingiva, are the soft tissue that surrounds the base of the teeth and holds them in place. The script mentions the gum as the pink stuff that the tooth sits in, highlighting its role in supporting the teeth and maintaining oral health. Understanding the function of gums is essential for overall dental care.

💡Cementum

Cementum is a calcified tissue that covers the roots of teeth and anchors them to the jawbone via the periodontal ligament. The video script refers to cementum as what helps to keep teeth in place, preventing them from falling out. This keyword is important for understanding the structural integrity of teeth within the mouth.

[MUSIC PLAYING]

(SINGING) So you gotta, gotta, gotta, gotta, gotta

have a kidney or two.

[CHEERS AND APPLAUSE]

That was the Foggy Liver Boys with "Gotta Have

a Kidney or Two."

Next up is Chloe and the Nurb with a song that's

sure to put a big toothy grin on your face.

[MUSIC PLAYING]

(SINGING) Teeth, teeth, in my mouth, how

I love them north and south.

You need them when you speak and chew.

They help you when you're singing, too.

Like we often do.

Woo hoo!

Babies get their first teeth at 6 months old.

20 baby teeth is all their baby mouths can hold.

They usually have all 20 by the time they're 3.

They're your primary teeth.

At around 6 years those little teeth get loose.

Bigger, stronger teeth start pushing them out.

By 12 or 13, you'll have all 28 of your adult teeth.

So there are 28 permanent teeth in all-- eight

more than you had when you were small.

But you're not done yet.

You still have four more to go-- your wisdom teeth.

Wisdom teeth, wisdom teeth.

By 21, you'll probably have those wisdom teeth for 16

over head and 16 underneath.

It's all the teeth that anyone could ever need

and the only set you'll get.

Teeth, teeth, you've got all kinds.

You keep yours, and I'll keep mine.

Brush them at least twice a day, and floss them, too,

if you want them to stay.

Till you're old and gray.

Yee hee!

You've got different kinds of teeth, whatever your mood.

The front four incisors help you bite your food.

There's four on top and four on the bottom, too-- doo,

doobity-doo.

Next are your canines, the spiky teeth,

helping tear tough food whenever you eat.

Every once has four-- two on top and two beneath,

just like a doggy's teeth.

Premolars and molars are the ones that chew.

They crush, grind, and smash up all of that food.

Add some spit, and you're ready to swallow it down.

Let's chew, chew, chew.

Chew, chew, chew.

Those wisdom teeth not only come in slow.

Once they're there, they might just cause you woe.

You don't really need them, so your dentist can take them out.

Bye, bye.

Teeth, teeth, they live in your jaw.

They help you munch, bite, nibble, and gnaw.

Some folks wear braces to get their teeth aligned

so their teeth work better and their smile looks fine.

The white part we see on top is the crown, and below

that the roots stretch really far down.

The enamel outside is what makes them hard and bright

if you brush them right.

The pink stuff the tooth sits in is your gum.

The roots of the teeth are covered by cementum.

It helps anchor those teeth to your jaw

so they don't fall out.

Inside that is the dentin around the pulp.

The pulp's nerves send pain messages

to your brain that says this soup's too hot

or this ice is too cold.

Brr.

Sometimes a cavity's what's hurtin' you, though.

Acid from plaque burned a hole through the enamel, which

is why we brush at least twice a day and floss at least once.

Nurb, do I have to floss every tooth?

Just the ones you wanna keep.

Teeth, teeth, keep them in your mouth.

Brush them twice a day or more north and south.

Floss each end every day, too, to remove most food

and nasty plaque, too.

Teeth!

Teeth!

We love those teeth!

You said a mouthful.
