The average, healthy
Tooth enamel, or the outer surface of your teeth, is built to take a beating. In fact, it is actually the hardest substance in your body, even stronger than your bones. Yet, although they are tough, your teeth can still crack or fracture just like bones do.
Teeth are commonly cracked (fractured), loosened, or knocked out (avulsed) when people receive a strong blow to the mouth.
The almost-solid mineral makeup of your teeth makes them the hardest substance in your body. This is how your teeth can withstand about 5600 pounds of pressure per square inch. However, no matter how strong they are are, they can still become weak over time depending on your actions.
This is equal to about 265 pounds of force. The reason why this is so important is because patients should understand that our teeth take a constant amount of brute force on a daily basis.
Your bones carry that weight every minute of every day as par for the course. Now, consider your teeth. Although paper-thin, the enamel that covers your teeth is much stronger than your bones. In fact, the only substance on earth that is stronger than enamel is diamond.
1. Tooth enamel is the hardest substance in the body. The shiny, white enamel that covers your teeth is even stronger than bone. This resilient surface is 96 percent mineral, the highest percentage of any tissue in your body – making it durable and damage-resistant.
The measurement results obtained using the mechanical and electric instruments are largely identical. They are in the neighborhood of 20 kgf and 50 kgf for incisors and molars, respectively, of male subjects. The results obtained for female test subjects were lower by an average of 10 kgf.
Tooth enamel is harder than steel, but breaks much easier. Tooth enamel is mostly hydroxyapatite, which is a mineral form of calcium phosphate. The apatite group of minerals scores a five on the Mohs hardness scale; which makes enamel the hardest biological material.
Enamel is the hardest substance in the human body, even harder than bone. It ranks 5 on the Mohs Hardness Scale, which means it is harder than steel, nickel, or iron. (By comparison, your fingernails have a hardness of 2 and your tooth dentin has a hardness of 3.
The average, healthy human tooth can withstand up to 30,000 pounds of comprehensive force and is much stronger than human bone. Each tooth is designed to perform a specific job and has its unique place in the human mouth.
It's important to schedule a dental exam as soon as possible following an oral injury. Even if the teeth appear fine, damage may have occurred beneath the gum line at the roots. Trauma to the tooth roots can cause a tooth to fall out days or weeks after an injury.
A tooth can be knocked out, either by a blow occasioned by sports, an accident or a brawl. The nerves, blood vessels and other supporting tissues will become damaged as well.
Fractures occur most often on the upper front teeth and the teeth toward the back of your lower jaw (mandibular molars). Though people commonly fracture one tooth, more severe injury or trauma may fracture multiple teeth. People with dental cavities have a higher risk of fracture, even with less severe trauma.
Pain when chewing: With a cracked, fractured, or split tooth, you may experience pain when chewing. This pain is most notably felt after biting down, when you release the bite. Pain when chewing or biting can range from mild to severe. The pain may come and go, and may be difficult to localize to a particular tooth.
Tooth enamel is the hardest material in the human body. It has to be so it can stand up to daily use for biting and chewing, then still be able to have a healthy, beautiful smile? Unfortunately, sometimes our teeth cannot handle the stresses we subject them to, and they start breaking.
Tooth enamel might be harder than keratin (what fingernails are made of), which means enamel is going to win the battle, but over time, keratin will win the war. Habitual nail-biting can erode, crack, and chip teeth. It can shift them out of proper alignment, resulting in gaps and bad bites.
After diamonds, tooth enamel is the second hardest compound in the world. The hardest substance in the body is tooth enamel, your teeth's natural defence system. The only naturally occurring substance harder than tooth enamel is diamond.
Enamel on our teeth is the strongest material in the human body; keratin is softer than enamel, thus you can scratch your fingernails with your teeth, but not other areas of your body with your fingernail. Keratin or fingernails is the second hardest material in the human body.
Impacted wisdom teeth are wisdom teeth that have failed to erupt properly. They are generally considered to be the most difficult teeth to extract. The higher the degree of impaction, the more difficult the extraction. However, experienced oral surgeons can perform this procedure efficiently and comfortably.
There is no hard and fast rule about the maximum number of teeth that can be pulled in one sitting without risking the patient's health. The answer to this question is going to change depending on your current oral health state and the advice of your oral surgeon.
The Guinness Book of Records has recognized a dentist from Offenbach for pulling a 37-millimeter tooth out of the mouth of a patient who had complained about severe pain.
Non-White or Yellow Teeth are Unhealthy
Teeth whitening treatments usually work by stripping or entering the outer enamel layer, which makes teeth weaker if done many times. So, more often than not, yellow teeth are actually stronger than pearly white ones–so long as they're cleaned regularly.
For teens and other age groups, the most vulnerable teeth to cavities and decay are those in the back of your mouth. Known as molars or premolars, this category includes wisdom teeth—if you keep them in, that is.
Just like humans, sharks have something called dentin inside of their teeth, which is a soft tissue-like material. They are also covered in hard enamel which is also very similar to humans. In fact, shark and human teeth are equally strong, but definitely not equally sharp.
