Do you know these things about your teeth? (Teeth) Let's talk!

Have you ever wondered what our teeth are and how important they are? Teeth are essential for the proper digestion of the food we eat. Simply put, our teeth are what break down food into pieces, crush it, and make it easier to swallow. So today, shall we talk a little more about these teeth?

How many teeth do we have?

An adult usually has 32 permanent teeth. However, not everyone has them. Some people are born with fewer teeth, which is called hypodontia in medical terms. Others have more teeth than they should, which is called hyperdontia .

When we are little, that is, usually from about 4 months to about 6 years old, we get baby teeth, right? Those baby teeth are our friends in childhood. There are usually about 20 of them. After a while, these baby teeth fall out, and our permanent teeth start to come in in those places. So baby teeth are not just a few teeth that fall out, but an important part that paves the way for permanent teeth.

Four types of teeth! What are they?

Not all teeth in our mouths are the same. Each tooth has a specific function. We mainly have four types of teeth. Let's see what they are:

• Incisors
• Canines
• Premolars
• Molars

Let's learn about incisors.

The front teeth in your mouth, the ones that show up when you smile, are called incisors . Most people have four on top and four on the bottom. These are your two front teeth and the teeth on either side of them. Because of the sharp edges on these teeth, when you start chewing a piece of food, these teeth help you break it up. Imagine that when you eat an apple, these are the first teeth you chew on, right?

What are canines?

These canines are called ``canines'' because they are shaped somewhat like a dog's. Compared to other types of teeth, they are a bit more pointed. Most people have four canines – one on the top right, one on the top left, one on the bottom right, and one on the bottom left.

These teeth help us to break down tougher things like meat, or crunchy vegetables like carrots. Some people also call these "eye teeth" because these teeth are located directly under our eyes.

What happens to the premolars?

These teeth are also called ``Bicuspids.`` Premolars are located between your canines and the molars, which are located deep inside your mouth.

Premolars have some characteristics of both incisors and molars. These teeth help to break, crush, and grind food.

Molars are the biggest workers!

Your molars are the big teeth inside your mouth. These teeth chew and grind about 90% of the food we eat. Imagine how big a job that is! An average adult has 12 molars – three on each side (top right, top left, bottom right, bottom left).

These wisdom teeth also belong to the group of teeth called the last wisdom teeth (or `third molars`) . So if you have had your `(Wisdom) teeth` removed, or if you were born without them, you may have up to 8 wisdom teeth.

These teeth are what precisely crush and grind food, making it easier to swallow.

How do all the teeth work together?

All these teeth in our mouths work together like a team. When we take a piece of food into our mouths, all these teeth help to break, tear, crush, and grind it. Then, our tongue and the upper part of our throat (Oropharynx) work together to form this food into a small ball, making it easier to swallow.

What does the inside of a tooth look like? (Anatomy of a tooth)

When you take a tooth, there are many important things inside, not just the visible part. There are two main parts to a tooth:

• Crown : This is the part of the tooth that you can see. That is, the part above the gum. This is covered by a very strong, protective layer called enamel . This enamel is what protects our teeth from scratches and impacts.
• Root : This is the part of the tooth that is held inside the jawbone. You can't see it because it's covered by the gums. The root is what holds the tooth in place, anchoring it to the jawbone, by a soft connective tissue called the periodontal ligament .

What are teeth made of?

Your teeth are made up of four main layers, each of which has a specific function.

• Enamel : This is the outermost, strongest protective layer of the tooth. It does a great job of protecting the teeth from bacteria that cause tooth decay. Did you know, enamel is the strongest substance in the human body! But once it wears away, it rarely regenerates.
• Dentin : This layer of tooth tissue lies just beneath the enamel. Dentin is not as strong as enamel. If the enamel wears away and the dentin is exposed, the tooth is more likely to decay. That's when teeth become numb.
• Cementum : This is the part of the tooth called cementum that surrounds the root of the tooth. This, along with the other tissues surrounding the tooth, helps to anchor the tooth to the jawbone.
• Tooth pulp : This is the innermost layer of the tooth, more like the heart. It contains nerves, blood vessels, and connective tissues . This is the part that gives life and sensation to a tooth.

Are teeth a type of bone?

Many people think that teeth are a type of bone. But that's not actually the case. Although teeth look like bones, their structure and function are very different.

If bones are broken, they can regenerate. But if a tooth is broken or fractured, it does not regenerate on its own. Also, teeth do not contain marrow like bones.

Teeth actually belong to a special group of organs called ``ectodermal organs.'' Your hair, skin, and sweat glands also belong to this group. Isn't that amazing?

Is there a way to number teeth?

Yes, dentists and health care workers use special numbering systems to identify teeth and keep records of them. Although there are various systems, the most commonly used in countries like the United States is the Universal Numbering System .

According to this system, adult teeth are numbered from 1 to 32. It starts with the third molar (the wisdom tooth) on the inner right side of the upper jaw. From there, the front two teeth are counted to the left. After counting the last tooth on the upper left (`#16`), the teeth are numbered to the lower jaw, starting again with the last tooth on the lower left (`#17`), and counting to the right, ending with the last tooth on the lower right (`#32`).

Even if you are missing a tooth, doctors will assign a number to that tooth to create your dental chart.

A similar system is used for baby teeth in young children, but instead of numbers, English letters (A to T) are used. This is like a map that makes it easier for doctors to keep records of your teeth.

What are the common medical conditions that can affect our teeth?

Teeth are a common source of problems. Tooth decay is the most common and most common of these. In fact, it is estimated that more than 90% of adults in the United States over the age of 40 have at least one tooth decayed. Tooth decay occurs when the enamel of the tooth is eroded by bacterial activity. When the dentin beneath the enamel is exposed, the bacteria eat away at the tooth even more.

Other common dental problems include:

• Teeth grinding (Bruxism) : Grinding your teeth together, whether you're sleeping or during the day, can wear away the enamel, damage your teeth, and cause pain.
• Teeth sensitivity : Do your teeth go numb when you drink cold water, eat a piece of ice cream, or drink hot tea? This often happens when the enamel has worn away or the roots of the teeth are exposed.
• Trauma to your mouth : Things like car accidents, sports injuries, and falls can cause teeth to break, chip, or even fall out completely.
• Tooth Discoloration : The color of teeth can change over time when you regularly consume things like tea, coffee, and some fruits. Also, the use of certain medications can cause teeth to become discolored.
• Impacted teeth : Sometimes, teeth can become stuck inside the gums or jawbone, preventing them from coming out properly. The best example of this is wisdom teeth impaction. However, this can happen to any tooth.
• Orthodontic misalignment : This includes things like crooked teeth, large gaps between teeth, crowded teeth, and crooked teeth. These can affect oral health and chewing.
• Abscessed tooth : Sometimes bacteria can enter the pulp of a tooth. When this happens, an abscess can form, causing severe pain.
• Gum disease : Although gum disease starts in the gums, if not treated properly, it can become severe, causing loose teeth and eventually tooth loss.

What are the symptoms of dental problems?

When there is a problem with our teeth, we may experience a variety of symptoms. Some of these include:

• Toothache
• Tooth numbness to cold, hot, and sweet foods
• Pain when chewing
• Gum swelling, bleeding
• Jaw swelling

If you feel something like this, it's best to see a dentist as soon as possible.

What are the common treatments for teeth?

There are many treatments for teeth. The doctor will decide what treatment to use based on the problem with your tooth. Here are some of the most common treatments:

• Dental fillings
• Dental crowns
• Dental bridges
• Dental bonding
• Teeth whitening
• Porcelain veneers
• Teeth braces
• Dental implants
• Dentures

How can I keep my teeth healthy?

To maintain healthy teeth and gums, it is important to take good care of your oral hygiene . Here are some simple things you can do to do so:

• It is essential to see your dentist regularly for check-ups and teeth cleanings. It is best to go at least once a year, or every 6 months if possible.
• Brush your teeth at least twice a day, for two minutes each time .
• Use a soft-bristled toothbrush and a toothpaste containing fluoride . Do not brush your teeth vigorously, as this can damage your gums.
• Floss between your teeth at least once a day. This removes food particles and debris that your toothbrush cannot remove.
• If possible, use an alcohol-free, antibacterial mouthwash . This can help reduce harmful bacteria in your mouth.

What do I do if I have missing teeth?

Sometimes, people are born with some teeth missing. Others may lose teeth due to tooth decay, gum disease, or accidents.

Whether or not you need a new tooth to replace a missing tooth depends on several factors, including the location of the missing tooth and your goals for your oral health.

Nowadays, there are many ways to replace missing teeth. Dental implants, dental bridges, and dentures are the main ones. You can talk to your dentist to choose the method that suits you best.

How does a tooth feel pain?

Every tooth has nerves and blood vessels inside it. These are what provide nourishment to the tooth. When something like an infection occurs in the tooth pulp, these nerves in the middle of the tooth start to feel pain. That's when we get a "toothache."
