  Sports and trivia games galore. Welcome to Kick Ass Daily, where

  we bring news, trivia, fun facts, and more just for curious
• 0:39
  kids like you. Today, we're going to talk about
• 0:42
  something you use every day, even if you don't think about it
• 0:45
  much. You use them when you eat, when
• 0:47
  you talk, and even when you smile for photos.
• 0:50
  That's right, we're talking about teeth.
• 0:53
  Have you ever wondered what your teeth are made of?
• 0:56
  Why you lose some and grow new ones, or how to keep them
• 0:59
  strong? Get ready to become a tooth
• 1:02
  expert. Let's start at the beginning.
• 1:05
  What exactly are teeth and why do you have them?
• 1:08
  Teeth are hard structures in your mouth.
• 1:11
  Their main job is to help you bite and chew food, making it
• 1:15
  easier to swallow and digest. Teeth also help you make certain
• 1:19
  sounds when you talk, and they give shape to your face.
• 1:22
  Imagine trying to eat an ale with no teeth.
• 1:25
  It would be really tough to break it into pieces.
• 1:28
  Now let's take a closer look at what teeth are made of.
• 1:31
  Each tooth might look pretty simple, but it actually has
• 1:34
  several important parts. The part you can see, the white
• 1:38
  bit that sticks out from the gums is called the crown.
• 1:41
  Underneath the crown is the root, which holds the tooth
• 1:44
  firmly in your jawbone. Your teeth are covered with a
• 1:48
  tough, shiny layer called enamel.
• 1:51
  Did you know enamel is the hardest substance in your entire
• 1:54
  body? Yes, even harder than your
• 1:56
  bones. Enamel protects your teeth from
• 1:59
  damage when you bite and chew. Under the enamel is another
• 2:03
  layer called dentin. Dentin isn't as hard as enamel,
• 2:06
  but it's still pretty strong. It helps support the enamel and
• 2:09
  gives your tooth its basic shape.
• 2:12
  Inside every tooth, there's a soft part called the pulp.
• 2:16
  The pulp has nerves and blood vessels.
• 2:18
  The nerves help you feel things, like if you bite into something
• 2:21
  cold or hot, and the blood vessels bring nutrients to keep
• 2:25
  your tooth healthy. Now let's talk about the gums.
• 2:29
  Gums are the pink soft tissue that surrounds your teeth.
• 2:33
  They help hold your teeth in place and protect the roots.
• 2:36
  Keeping your gums healthy is just as important as taking care
• 2:40
  of your teeth. Here's a quick trivia question
• 2:43
  for you. Do you know what the area where
• 2:45
  your teeth and gums meat is called?
• 2:50
  It's called the gum line. The gum line is where plaque, a
• 2:54
  sticky film of bacteria, loves to hide.
• 2:57
  That's why you need to brush along the gum line every day.
• 3:01
  Moving on, how many teeth do you think kids have?
• 3:03
  When you're born, you actually have no teeth showing.
• 3:07
  But hidden under your gums, your very first teeth are already
• 3:11
  forming. These are called primary teeth
• 3:14
  or baby teeth. Most babies start to get their
• 3:17
  first tooth around six months old.
• 3:19
  By the time you're about 3 years old, you'll usually have all 20
• 3:23
  baby teeth, 10 on the top and 10 on the bottom.
• 3:27
  Baby teeth are important because they help you chew food and
• 3:30
  learn to talk. They also make space in your
• 3:32
  mouth for your grown up teeth, which will come in later.
• 3:35
  Now here's a fun yes or no question.
• 3:39
  Do all of your baby teeth fall out at the same time?
• 3:45
  The answer is no. Baby teeth fall out one at a
• 3:48
  time, usually between the ages of 6:00 and 12:00.
• 3:51
  As each baby tooth falls out, an adult tooth, also called a
• 3:56
  permanent tooth, grows in its place.
• 3:59
  Did you know that you'll have more adult teeth than baby
• 4:01
  teeth? Most kids and adults have 32
• 4:04
  permanent teeth once all of them have come in.
• 4:07
  That includes 4 special teeth at the very back called wisdom
• 4:10
  teeth, which usually show up when you're a teenager or even
• 4:14
  older. Let's talk a bit about the types
• 4:16
  of teeth you have. Not all teeth do the same job.
• 4:20
  There are 4 main types of teeth in your mouth.
• 4:23
  First, there are incisors. These are the sharp, flat teeth
• 4:27
  at the front of your mouth, 4 on the top and four on the bottom.
• 4:31
  Incisors are great for cutting food, like when you take a bite
• 4:34
  out of a sandwich or a carrot. Next to your incisors are your
• 4:38
  canines. You have four of these pointy
• 4:41
  teeth, 2 on the top and two on the bottom.
• 4:44
  Canines help you tear food, like when you bite into a piece of
• 4:47
  chicken or an apple slice. Behind are canines are your
• 4:51
  premolars, also called bicuspids.
• 4:54
  There are 8 premolars in total, 4 on top and four on the bottom.
• 4:58
  Premolars have flat surfaces with ridges which help you crush
• 5:02
  and grind food. And finally at the very back you
• 5:06
  have your molars. Molars are big flat teeth that
• 5:10
  help you grind up food into little pieces, making it easier
• 5:13
  to swallow. Most people have 12 molars,
• 5:16
  including the wisdom teeth. Here comes another trivia
• 5:20
  question. Which type of teeth do you use
• 5:22
  the most when you chew a crunchy apple?
• 5:28
  The answer is your molars. Molars are perfect for grinding
• 5:32
  crunchy foods into tiny pieces. Now let's talk about how teeth
• 5:36
  grow and change as you get older.
• 5:39
  When a new tooth is ready to come in, it pushes through the
• 5:42
  gum, which sometimes feels a little sore.
• 5:45
  This is called teething, and it happens first when your baby
• 5:49
  teeth come in and later when your adult teeth replace them.
• 5:53
  Losing baby teeth can feel a little strange, but it's a
• 5:56
  normal part of growing up. Some kids even look forward to
• 5:59
  the day their teeth get wiggly and fall out, especially if they
• 6:03
  have fun traditions like leaving a tooth under their pillow.
• 6:06
  When your new adult teeth grow in, they are usually bigger and
• 6:10
  stronger than your baby teeth. Did you know that your teeth are
• 6:13
  always changing even after they grow in?
• 6:16
  For example, the enamel on your teeth can wear down if you eat
• 6:19
  too many sugary snacks or don't brush and floss properly.
• 6:24
  That's why taking care of your teeth every day is super
• 6:27
  important. Here's a quick yes or no
• 6:29
  question for you. Can your teeth repair a big
• 6:31
  cavity or hole all by themselves?
• 6:37
  The answer is no. Teeth can't heal big cavities on
• 6:40
  their own, so you need to visit a dentist to fix them.
• 6:44
  Let's talk about keeping your teeth healthy and strong.
• 6:47
  Brushing your teeth twice a day with toothpaste helps remove
• 6:50
  food and plaque. Plaque is a sticky film of germs
• 6:53
  that can cause cavities if it's not cleaned off.
• 6:57
  Flossing once a day helps clean between your teeth where your
• 7:00
  toothbrush can't reach. Here's a trivia question.
• 7:04
  What is the name of the mineral and toothpaste that helps
• 7:06
  protect your teeth from cavities?
• 7:11
  The answer is fluoride. Fluoride makes your enamel even
• 7:15
  stronger and help stop cavities from forming.
• 7:18
  Eating healthy foods is important for your teeth. 2
• 7:22
  Foods like milk, cheese, yogurt, leafy greens, and crunchy fruits
• 7:27
  and vegetables help keep teeth strong.
• 7:29
  Sugary snacks and drinks like soda and candy feed the bacteria
• 7:33
  in your mouth and can cause cavities if you have them too
• 7:36
  often. Did you know that there are
• 7:38
  people whose whole job is to help you keep your teeth
• 7:41
  healthy? Dentists and dental hygienists
• 7:43
  check your teeth, clean them, and teach you how to take care
• 7:47
  of your mouth. Most kids should visit the
• 7:49
  dentist every six months for a checkup.
• 7:52
  Here's a final yes or no question.
• 7:55
  Do you need to brush your gums and tongue as well as your
• 7:57
  teeth? The answer is yes.
• 8:03
  Brushing your gums and tongue helps keep your whole mouth
• 8:06
  fresh and healthy. Let's recap what we learned
• 8:09
  today. Teeth are amazing structures
• 8:12
  that help you eat, talk, and smile.
• 8:15
  They have different parts like enamel, dentin, pulp, and roots.
• 8:19
  You start with 20 baby teeth, which are later replaced by 32
• 8:24
  adult teeth. There are four types of teeth,
• 8:27
  incisors, canines, premolars, and molars, and each one does a
• 8:31
  different job. Taking care of your teeth by
• 8:33
  brushing, flossing, eating healthy foods, and visiting the
• 8:37
  dentist is the best way to keep your smile bright.
