Have you ever stood in front of a mirror and looked at your teeth? The shiny, usually white outer layer you see is what we call "tooth enamel." It's like a shield for our teeth. But many people don't know how strong this shield is, how it can be damaged, and why it's important to protect it. So today, let's talk about the protector of your smile: tooth enamel.
Simply put, what is this tooth enamel?
Simply put, tooth enamel is the protective outer covering of each of your teeth. Its main function is to protect the part of the tooth that you see above the gum line, the tooth crown, and the delicate layers beneath it.
Can you tell me something you can't even imagine? This tooth enamel is the hardest, that is, the strongest substance in our body. Yes, it is stronger than the bones in your body. Imagine how amazing that is!
However, no matter how strong it is, it can wear away over time. Dental plaque, acids in the foods we eat and drink, and everyday dental use can all damage this enamel. The most important thing is that once it wears away, it can't be rebuilt. It's like broken glass. That's why we need to keep our teeth clean and protect our enamel.
Enamel is the natural protective coating on your teeth. If that coating is removed, the sensitive parts inside the tooth are exposed.
What exactly does enamel do to our teeth?
The main function of enamel is to protect teeth from damage. Specifically, it protects the two layers inside the tooth called dentin and tooth pulp.
- Dentin: This is located beneath the enamel. It is slightly softer than enamel.
- Pulp: This is the innermost part of the tooth. This is where the nerves and blood vessels are located.
Imagine what happens when the protective layer called enamel wears away. Then the `dentin` underneath comes out. That's when cavities start to form. If it gets worse, infections can occur and damage the tooth pulp. That's when severe toothaches start. Also, when the enamel wears away, your teeth start to feel numb even if you drink a little cold water, a hot cup of tea, or eat something sweet.
What does enamel look like? What is it made of?
Many people think that the white color of teeth comes from enamel. But that's not the truth. Enamel is actually slightly transparent. Like thin glass. So where does the color of the teeth we see come from? That color comes from the layer called `dentin` that lies beneath the enamel. This `dentin` can vary in color. Some people have a grayish white color, while others have a light yellow color. So, the color of your teeth is determined by the color of this `dentin` and the transparency of the enamel above it.
Things made of enamel
This is amazing. 95% of enamel is made up of the minerals calcium and phosphorus . These minerals combine to form very strong tiny crystals (crystallites). That's what makes it so strong. The rest is made up of water (4%) and proteins (1%).
What are the factors that cause enamel to be damaged, that is, worn away?
We call this process of enamel erosion `(Tooth Enamel Erosion).` When this happens, the layers inside the tooth are exposed to the light. Then the chances of developing cavities are much higher. Also, the teeth become numb, the teeth quickly turn yellow, and stains begin to form. So, let's see what are the main reasons that affect this.
| The reason for enamel wear | How does that happen? |
|---|---|
| Sugary foods and drinks | When you eat sugar, bacteria in your mouth use that sugar to produce acids. These acids gradually dissolve the enamel. Toffee, chocolate, and sweetened drinks are the main enemies of this. |
| Highly acidic foods and drinks | Some drinks (e.g. cola, soda, some fruit drinks) and foods (e.g. lemon, vinegar) contain acids directly. These can directly dissolve enamel. |
| Dry Mouth | Saliva in the mouth has a big job. That is to wash away bacteria and acids in the mouth. Since a person with dry mouth produces less saliva, acids stay on the teeth for longer, damaging the enamel. |
| Friction and bad habits | Enamel naturally wears down a bit from chewing food over time. However, habits like biting your nails, tearing open packets with your teeth, and holding a pen in your mouth can also wear down enamel more quickly and cause it to break. |
| Genetics | Some people are born with slightly thinner enamel. This condition is called ``Enamel Hypoplasia.'' People with this condition are more likely to have their enamel damaged. |
| Stomach acid | When gastritis becomes severe, conditions like GERD cause stomach acid to flow up into the throat. If this acid gets on the teeth, it can cause severe damage to the enamel. People with eating disorders like bulimia are also at risk. |
| Teeth Grinding | Many people grind their teeth unknowingly, especially in their sleep. This excessive pressure weakens the enamel, which can lead to chipping and cracking of the teeth over time. |
Okay, so how do we protect this precious enamel?
Now that you know how valuable enamel is and how it can be damaged, the best part is that there are many simple things we can do to protect it. Let's take a look at what they are.
- Brush your teeth twice a day. This is the most basic thing. When you brush your teeth, you remove the plaque and bacteria on your teeth. But remember, use a soft-bristled toothbrush. And don't brush too hard. Doing so can damage the enamel.
- Use toothpaste that contains fluoride. Fluoride is a mineral that helps to remineralize enamel. Like calcium and phosphorus, fluoride is essential for enamel.
- Floss between your teeth daily. No matter how well you brush your teeth, food particles and gum can get stuck in the tight spaces between your teeth. Flossing can remove these.
- Limit foods and drinks high in sugar and acid. Reduce toffee, starchy foods, soda, and sweetened beverages as much as possible. These are the biggest enemies of enamel.
- If you drink acidic drinks, drink them through a straw. This will help reduce the amount of acid that gets stuck to your teeth.
- Drink plenty of water. Sipping water throughout the day helps wash away bacteria and food particles in your mouth.
- Chewing sugar-free gum. This increases saliva production in the mouth. You now know that saliva protects enamel.
- Reduce the pressure on your teeth. If you grind your teeth in your sleep, see a dentist and get a mouth guard. If you have a habit of biting your nails, try to stop it. Don't chew ice cubes.
- Get treatment for other medical conditions. If you have a dry mouth condition, such as GERD, be sure to see your doctor and get the appropriate treatment.
- See a dentist regularly. It is very important to see a dentist at least once a year to have your teeth checked and cleaned.
Can worn enamel be restored? Will whitening your teeth harm you?
This is a problem that many people have. The truth is, enamel that has been completely worn away cannot be regrown. It does not regenerate naturally.
However, if the enamel has been damaged to some extent, that is, when it is just beginning to wear off, dentists can strengthen it further. They use things like fluoride treatments. These remineralize the enamel and strengthen it.
If a tooth has been severely damaged, your dentist may recommend placing a dental crown over it to protect it from further damage.
About Teeth Whitening
If done correctly and professionally, teeth whitening will not damage the enamel. However, some products can dry out your teeth. If you want to whiten your teeth, be sure to talk to a dentist about a safe method.
