At an auction in Pittsburgh, England in 2011, a tooth belonging to John Lennon sold for just over US$31,000.

How much are your teeth worth?

Teeth are amazing little miracles. They brighten our smiles, we use them to speak and we chew with them more than 600 times at every meal. Yet, in a society where 1 in 5 Americans age 75 and older without Teeth Last Many people may not realize that teeth are designed to stay with us throughout our lives.

I am a dentist and assistant professor in clinical dentistry and craniofacial regeneration research.Researchers like me are still deepening our understanding of tooth growth, with the ultimate goal of providing patients with the service of on-demand regrown teeth.

In the process, I have developed a reverence for natural teeth and the overall beauty of these biological and mechanical masterpieces.Designed for a lifetime of function

The secret to the longevity of teeth lies not only in their durability but also in the way they are attached to the jaw – picture a hammer and its handle. The complex interface between the various tissues of C serves the purpose of stability and stabilization of each tooth; Each one alone is a biological miracle.

For anchorage, cementum, ligament and bone hold the tooth to its root portion which is buried beneath the gum.The ligament, a soft tissue about 0.2 millimeters wide (about the diameter of four hairs), connects the cementu of the root at one end to the jawbone at the other end. It serves to stabilize the tooth as well as control its movement during chewing. However, for stability, the secret lies in the enamel, dentin, and pulp – the focus of this discussion.

Enamel is a protective covering that covers the visible part of the tooth above the gum. Due to its high mineral content, enamel is the hardest tissue in the body.It is needed because it acts as a shield against the constant impact of chewing.Enamel does not contain cells, blood vessels, or nerves, so it is lifeless and insensitive. The enamel is also non-regenerative. Once destroyed by decay or cracked by abuse such as chewing ice, biting nails or opening a bottle – or being touched with a dental drill – that part of our priceless enamel is lost forever.

Because it connects to the germ-filled world, enamel is also where decay begins.When acid-producing bacteria accumulate on unbrushed or poorly brushed teeth, they easily dissolve the minerals in the enamel.

Unlike hair or nails, non-invaded enamel is not sensitive. Decay progresses painlessly through a 2.5-millimeter thick (one-tenth of an inch) layer of enamel. When caught at that stage during a dental checkup, the dentist can treat the decay with a relatively conservative filling. which hardly compromises the structural integrity of the tooth.

Due to its high mineral content, enamel is hard.Its lifelong support is provided by a more flexible infrastructure – dentin.

Dentin and Pulp – Body and HeartWith a lower mineral content than enamel, dentin is the flexible body of the tooth. It is a living tissue composed of parallel small tubes that contain fluid and cellular extensions. Both originate from pulp.

The pulp is the soft tissue core of the tooth.Rich in cells, blood vessels and nerves, it is the tooth's life source – its heart – and the key to its longevity.

Like smoke detectors that communicate with a remote fire station, the cellula extension within the dentin sense decays as soon as it breaks through the non-sensitive layer of enamel into the dentin. Once the extensions send a danger signal to the pulp, our tooth sensitivity alarm goes off: The tooth's hearing is in flames. The inflamed pulp initiates two protective actions. The first is to secrete an additional layer of dentin to delay the oncoming attack.Second, I have a toothache, call to go to the dentist.

The quicker the travel, the less drilling and the smaller the fill. I take care of the timing, most of the natural tissue of the tooth will be preserved and the pulp will probably return to its healthy state. If caught too late, the pulp gradually destroys.

Without its heart, a lifeless tooth has no defense against further Deka attack.Without a hydration source, dried dentin will sooner or later crack due to constant chewing. Furthermore, a tooth that has already lost a significant portion of its natural structure due to decay, cavity preparation or root canal instrumentation becomes vulnerable and its lifespan is limited.

In other words, a tooth is never the same without a heart. Pulpless, the tooth loses its womb-to-tomb stamina and Mother Nature's lifetime warranty.

Teeth Coming Together More complex than pearls within an oyster – and more precious – tooth formation involves layered mineral deposits within our jawbone.As tooth development progresses in the process of ultimate cellular engineering, the cells of the above six tissues – enamel, dentin, pulp, cementum, ligament and bone – multiply synchronously with each other to form specific interlocking interfaces. , specialization and mineralization occur: from enamel to dentin, from dentin to pulp, from cementum to dentin and from cementum to ligament to bone.

With advancements like 3D printing, the tooth crown grows completely vertically. Simultaneously, the root continues its expansion and eventually leaves the crown to emerge from within the bone beyond the gum into the gum – a phenomenon known as tooth eruption. This is the time around age 12 when our set of adult teeth is complete. These pearls are made to last a lifetime and are undoubtedly worth preserving.Save your teeth, go to the dentistTooth decay, the most common disease in humans, can be predicted and prevented. The sooner it is caught, the more the integrity of the tooth can be preserved.

Since the process starts painlessly, it is important to visit the dentist regularly to keep those deadly germs under control.

During your checkup visit, the dental professional will clean your teeth to prevent early decay. The good news will be no news to you if you are diligent with your daily preventive measures – enough to make anyone smile.(th conversation) PYPY
