Molars: Your molars are your twelve back teeth—six on top and six on bottom. They are your strongest and widest teeth.
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.
Reader's Digest quoted Adriana Manso, a clinical professor in UBC's faculty of dentistry, for an article about how whitening agents weaken teeth. He said “bleaching products contain hydrogen peroxide that diffuses through the enamel.
What is the most difficult tooth to extract? 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.
Tooth enamel is the hard, shiny, white outer layer of your teeth that covers the underlying tissues. It's the hardest substance in the human body – even stronger than bone – and is made up almost entirely of minerals.
You might be wondering, how strong are crowns on the front teeth? While they're not as strong as porcelain fused to metal, front teeth are subjected to less pressure than molars when you chew, so a durable metal isn't necessary.
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.
The most commonly fractured teeth are the mandibular molars,[8,9,10,11] perhaps due to pointy, protruding maxillary molar palatal cusps[12] occluding powerfully into the mandibular molar central grooves.
Canines – Your canines are the next teeth that develop in your mouth. You have four of them and they are your sharpest teeth, used for tearing apart food.
Many of the front teeth are round, so they can be removed without damaging bone quite easily. However most of your back teeth have two or three roots and cannot just be “pulled out” without breaking something.
Healthy teeth are usually off-white or slightly yellowed, and teeth naturally darken over time. But if you notice brown, black, or green stains on your teeth, you may have a chronic condition or need a thorough dental cleaning.
White teeth have a very light shade of yellow and are the healthiest type of teeth. The colour of these teeth comes from a combination of genetics and the amount of time you spend brushing your teeth each day. Slightly yellow teeth have a mild yellow tinge that is barely noticeable.
Natural Enamel Thickness & Translucency
However, the underlying dentin layer has a slightly yellowish color. This yellowish hue shows through the enamel in almost everyone, but more so for those with naturally thinner or more translucent enamel. So your yellow teeth may be perfectly normal due to your genetics!
Denmark: In the top spot, with an impressive DMFT Score of 0.4 At the very pinnacle of the list have Denmark. The data indicates Denmark has the best oral health of all the countries in the entire world.
For that, you can thank evolution. Wisdom teeth are known as vestigial structures. These are parts of our body, such as the tailbone, that once had a use but no longer do in our modern lives. Wisdom teeth served a purpose long, long ago when we foraged for foods like twigs and tough, raw meats.
Tooth Numbering System
#1 is your upper right wisdom tooth. Each tooth then progresses up one number all the way across to the 3rd molar (wisdom tooth) on the left side of the mouth (#16).
Canines. Next to the lateral incisors are our canines, which are the sharpest and longest teeth in our mouths. This enables them to grip and tear food, particularly meat.
Dental professionals consider a square-shaped jaw one of the most attractive because it shows that someone has a strong jawline and thin lips. On the other side of that spectrum is a round-shaped jaw with protruding teeth that can make a person look like they have an overbite or underbite.
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.
Your teeth are well-equipped to deal with the bite pressure itself. Actually, teeth are able to resist a compressive force of about 30,000 pounds.
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.
Dental crown materials like porcelain and ceramic may sound delicate, but they are just as strong as natural teeth when it comes to chewing and biting. In fact, zirconia crowns are even more durable than natural tooth enamel.
Crowns made of porcelain or fused material survive for five to fifteen years. Metal crowns have a 20+ year lifespan. Crowns made of gold and zirconia are durable for life. Additionally, experts think that front-tooth crowns last longer than back-tooth crowns.
In most cases, at least two millimeters of tooth structure is required in order to place a crown. Generally, this means that at least one-quarter of the visible portion of the tooth must be present and healthy enough to support a dental crown.
1. Their Permanent Teeth Are Starting to Come in. If your child is about 6-7 years old and their permanent teeth have started to erupt, you may notice that their permanent teeth look quite a bit more yellow than their baby teeth. Good news: this is normal.
