Want to know, what is the hardest substance in the human body? In human body have the hardest substance.
Your brain not believe the name of the hardest substance in the human body. But it’s true. Let’s know.
What is the hardest substance in the human body?
Maybe you will surprise to hear that tooth enamel is the hardest substance found in the human body.
The hardest substance in the human body is the enamel found on our teeth.
Tooth enamel can vary in color from light yellow to greyish white and is partly transparent, which is why, together with dentin.
It is responsible for the color of the teeth. Teeth are made up of various tissues, and one of them is tooth enamel. It constitutes the outermost layer of the tooth.
It is a tissue made up of a mineral called hydroxyapatite and proteins.
Tooth enamel hardness is provided by hydroxyapatite, which is the hardest mineral in the human body.
The tooth is made up of 3 main layers: the outer layer called enamel, the middle layer called dentin, and the inner layer called the pulp.
- The tooth enamel is translucent and insensitive to pain because it lacks nerve endings.
- Dentin is the layer that is below the enamel and is responsible for the color of the tooth.
- And finally, more interior than dentin is the dental pulp, formed by a tissue that contains the vascular-nervous package of the tooth, composed of nerves, a vein and an artery.
However, it has a fundamental problem and that is that it cannot be regenerated, that is once enamel is lost, it is lost forever and is not recovered.
How to care for tooth enamel?
It is convenient to comply with the following recommendations:
- Maintain a balanced diet. If you do not stop consuming sweet foods, it is preferable to do so when the mouth has a greater amount of protective saliva, that is, between meals.
- Eat a healthy and healthy diet.
- Chew sugar-free gum. The combination of saliva with sugar-free gum stimulates salivary flow, further neutralizing acids.
- Avoid the habit of smoking.
- Topical application of fluoride to prevent tooth decay and remineralize enamel for tooth protection.
- Brushing your teeth at least twice a day with a soft bristle brush. Clean between the teeth daily with dental floss or interproximal brushes. Visit the dentist frequently for professional oral cleanings.
On the other hand, it is very important that both the toothpaste used and the mouthwash are reinforced with fluoride, which is an element that helps to strengthen tooth enamel.
What is tooth enamel?
Maybe you think that the strongest part of your body is bones, skin. Well, no. Although little is said about it, tooth enamel is the hardest part of the entire body.
Tooth enamel is a mineralized tissue, a translucent layer that covers our teeth and is approximately three millimeters thick.
And despite being so powerful it does not regenerate, so it is extremely important to protect it because once it is lost it is impossible to recover it.
The wear of this layer is a recurring problem, it is characterized by the loss of it, and causes that over time the teeth become more fragile and susceptible to sensitivity, fracture and the appearance of dental caries.
What is tooth enamel made of?
Tooth enamel is composed of a dense network of hydroxyapatite crystals.
That is, the enamel of your teeth is made up mostly of inorganic material (90%) and only a small amount of organic matter (2.9%) and water (4.5%).
The inorganic material in enamel is similar to apatite.
Analysis of the mineral components of enamel reveals that calcium in the form of phosphate predominates in them.
Of which the most abundant is hydrated calcium, called hydroxyapatite due to its chemical characteristics.
Proteins can be isolated in several different fractions, and these generally contain a high percentage of glycine, glutamic acid and serine.
Enamel protein is of a structural type, very special due to its constituent amino acids and which has been called enamelin or amelin. The enamel structures are:
- Cousins. Arranged obliquely on the enamel surface.
- Hunter-Schernger bands: Also known as alternating dark and light bands of different or variable width.
What is dental erosion?
Dental erosion is damage to the enamel of your teeth. This can lead to weakness of your teeth and increased sensitivity of the tooth.
We speak of dental erosion when the demineralization and destruction of the enamel are caused by acids other than the bacterial plaque.
Over time, the tooth enamel undergoes wear that causes it to lose its ability to protect the teeth, in a process that is called demineralization.
How is it lost?
There are several factors that can damage the enamel on your teeth. What drinks can affect tooth enamel and how do they do it?
Effervescent and carbonated drinks that contain sugar, artificial sweeteners, acids, caffeine, colors, flavorings, carbon dioxide, preservatives, water, and sodium.
The high content of sugars and acids help substantially in the appearance of tooth enamel erosion and cavities.
Alcoholic beverages cause significant dehydration in the oral mucosa that causes the gums to become weaker.
This is because the acidic agents of the alcohol come into contact with the teeth and wear down the enamel.
Regular consumption of alcohol can cause dental erosion, that is, holes in the teeth that expose the dentin.
Coffee is one of the beverages that affect tooth enamel as it contains tannin that causes staining.
This demineralization can be accelerated by the intake of certain foods and beverages, in general, all those with a high content of added sugars or acids, such as soft drinks, candies, etc.
To protect tooth enamel, it is best to carry out good and correct daily hygiene, brushing after each meal, flossing to prevent food from getting between the teeth and using mouthwash.
