Why do we Need to Brush Our Teeth?

Why do we Need to Brush Our Teeth?

Brushing teeth is very important that is what everybody says. Our parents remind us to brush teeth before going to bed and in the morning too. It keeps our teeth clean but why we have to keep our teeth clean. What is the reason?  The reason is when we eat something or we sleep our layer of bacteria covers our teeth, this layer of bacteria is called plaque. We brush it twice a day to remove it. If you don’t brush your teeth, you get cavities, and then only dentist can help you to remove cavities. 

It is almost bed time. But before you get ticked in don’t forget to brush your teeth.

We have to brush our teeth at least twice a day. But why do we do so?

We’ll, have your teeth ever felt like just.. yucky? Like at the end of the day? Or the first thing in the morning?

I really like brushing my teeth because it gets rid of that icky feeling. And because it feels good because it is good.

We brush our teeth to keep them clean and healthy so that they can keep helping us our whole lives. After all, how would you crunch up a cracker or bite into an apple  without them?

Without teeth, you’d have very few choices of foods that you could eat. So you’ve got to take care of them.

What Are Teeth Made Of?

Now you can’t tell by just looking at them, but your teeth are actually made up of different layers. The part that you can see on the outside is a super hard shell called the enamel which is mostly made up of minerals. Enamel is the strongest stuff in your whole body, even stronger than bone. But unlike your bones, a tooth can’t heal itself if it is broken. And your teeth aren’t hard enamel all the way through.

Just below the tough outer layer, there’s another layer called dentin, that’s not as hard. And below that, there’s the inner layer of the tooth called the pulp, which has blood vessels and nerves inside it.

And this part of your tooth is super sensitive. So in order to protect the delicate pulp in the inside of your teeth, you have to take really good care on the outside. And the best way to do that, is to clean them up after you eat.

What foods cause tooth erosion?

Because food can damage even those tough outer layers of the teeth. How?

We’ll, you might think that you ate every last bite of the crackers that you had for a snack, but the truth is, some very small pieces of food are still hanging around in your teeth. That’s because your teeth aren’t all shiny and smooth. They have lots of bumps and ridges that help you grind down your food. And there are lots of small spaces between them too. These are the places where it is easy for food to get stuck and hang out all day.

Which is kind of gross! But you know what’s even more gross? You are not the only one enjoying these leftovers. There are lots of tiny little things that call your mouth home. These are called bacteria. They are way too small to see, but they are definitely in there.  And there are a lot of them! In just your mouth alone, there are more bacteria than there are people on Earth.

Some kinds of bacteria are really good to have! Others just kind of hang around and are neither good morning bad.

And then there are some who are pretty bad house guests and you don’t want them staying in your mouth for too long.

One type of bacteria loves to eat the same stuff that you do, especially sugars and starches, that means things like cookies, chips, bread, candy and cereal. These bacteria hang around on your teeth and in your mouth basically eating your left overs. And once they are done eating those tiny bits of food they release acids which can really hurt your teeth.

This acid causes holes which are called as cavities to form in the enamel of your teeth. And cavities can really hurt. They might even make it hard for you to eat if they get too big. But the good news is that when you brush your teeth you clean away the food that those bacteria love so much and you sweep away some of the bacteria that may be lurking around. And with the bacteria goes away that icky, gross feeling on your teeth.

Why do we need to brush our teeth?

So, we brush our teeth before we go to bed to get rid of all those tiny bits of food we’ve been eating during the day and to clean out the bacteria that are hiding in our mouths.

Fewer bits of food in there and fewer bacteria means you have less of a chance of getting  cavities! But! You should brush your teeth in the morning too! Because even though you brushed the night before, there are always some bacteria sticking around in your mouth. And while you were sleeping, those little guys were partying it up!

So when you brush your teeth in the morning, you are starting your day off with a nice clean mouth. That is why you should brush your teeth at least twice a day, in the morning and at night.

Taking care of your teeth will make sure they stay strong and healthy, so you can keep eating good food – which keeps the rest of your body healthy.

Once your teeth are clean, it will be time for you to head to bed.
