Parents should explain the importance of teeth for kids right from their formative years. It helps them inculcate the habit of keeping their teeth healthy and pristinely clean from a young age. You should supervise the children when they have just started brushing their teeth and keep pushing them as they could show resistance at times. That is pretty normal among toddlers and even young children. You can teach them the benefits of brushing and what happens if they don’t brush right. Sharing interesting facts and asking trivia sometimes can keep them going. Plunge into this post will help you make the task easier.

What Are The Parts Of A Tooth?

Before we get to the fun facts about teeth, let’s learn about the parts of a tooth. Every tooth has the following parts (1) (2) (3).

What Are The Parts Of A Tooth

  • Crown

The whitish part of the tooth that is visible in the mouth is called the crown. The crown of the tooth helps us bite and chew our food and also enables us to pronounce words correctly. Did you know that the crown of your teeth is made up of three layers? It has the following layers.

  • Enamel: This is the outermost and strongest layer of the tooth. Its main functions are to withstand the pressure of chewing, protect the teeth from harmful bacteria, and withstand the changes in temperature from hot and cold foods.
  • Dentin: The dentin is located just below the enamel. The dentin protects the delicate and sensitive pulp.
  • Pulp: This is the innermost layer of a tooth. It consists of connective tissue, nerves, and blood vessels that help nourish the tooth and keep it healthy.
  • Root

While we can see the crown of the teeth, do you know what keeps them firmly fixed in your jaw? It’s the root. Every tooth has a root that anchors it strongly in your jaw. Although we cannot see this part of the tooth, it is an integral part of its structure.

Just as the enamel protects the crown of your teeth, the root is covered by a layer called the cementum. Apart from the cementum, the soft gums also help protect the roots of your teeth.  

Types Of Teeth

Children are observant and often pose questions such as, “Why is this tooth different from the other one?” or “Why are my front teeth different from my back teeth?” So, it is vital to teach children that we have different types of teeth, and each type plays an important role in our mouth (2) (3) (4).

  • Incisors

These are your front teeth, and you have four of these teeth on the top and four on the bottom. Incisors are flat and thin and enable you to cut your food into smaller pieces for easy chewing.

  • Canines

Have you seen two pointy teeth, one on each side of your incisors? These are your canines, also called cuspids, and we have four of them in our mouth. These teeth look sharp and help us tear food, especially meat, into smaller pieces.

  • Molars

The last teeth in each jaw are your grinders or molars, and they do precisely as their name suggests–they grind food to make it easy for us to swallow! They are the last teeth to erupt in our mouth, and we have eight or 12 molars in our mouths.

  • Premolars

Right next to your pointy teeth are your premolars, which look like your canines and also have a chewing surface like your molars. We have four premolars in our upper jaw and four in the lower. Premolars are absent in milk teeth.

30 Interesting Facts About Teeth For Children

Here are some fun and interesting teeth facts for kids (5) (6) (7) (8) (9) (10) (11) (12) (13) (14) (15) (16).

  1. We all have two sets of teeth–the milk teeth or baby teeth and permanent or adult teeth.

  1. A fractured bone can be repaired, and it heals. However, damaged enamel cannot be regrown or repaired naturally.
  1. Did you know your mouth is full of bacteria? Some are good for your mouth, and the others turn harmful when they find excess sugar and starch in your mouth. This is what leads to cavities!
  1. The pulp inside baby teeth that you have are excellent sources of stem cells. Thus, you could preserve them.
  1. When you brush your teeth, you must clean your tongue too! Not cleaning your tongue causes bacteria to accumulate, leading to more cavities.

  1. Before it was discovered that tooth decay is caused by the bacteria in the mouth, people believed that it was caused by tiny, wriggly worms.
  1. Did you know that tooth decay was not as common in the previous generations? This is because the diet in the olden days was not as laden with sugars as it is today.
  1. Toothpaste is not new. Ancient Egyptians prepared their toothpaste using powdered oxen hoove’s ashes, myrrh, pumice, and burnt eggshells.
  1. More than 700 different species of bacteria can be found in your mouth. Milk, cheese, and curd are some dairy products that are healthy for your teeth as they are rich in calcium.
  1. Did you know your teeth shape, size, appearance, and arrangement in the mouth are genetic? You inherit these genes from your parents.
  1. The shape of animal teeth is directly related to their diet. Since a plant-based diet is hard to digest, herbivores have large grinders that help them grind and chew their food. Carnivores need sharp, pointed teeth to tear into the flesh of their prey, and so, their teeth are pointy and sharp.
  1. Some mammals, such as kangaroos and elephants, have more than two sets of teeth during their lifetime.

Teaching children about teeth and their importance goes a long way in building good dental habits in them. Good oral health is the key to good overall health. Providing factual yet simple answers to children’s queries about their teeth also expands their knowledge and boosts their cognitive abilities during their growing-up years.
