Bone vs Teeth – 5 reasons they are different from each other

Teeth and bones are both hard, white and heavy with calcium, but that doesn’t make them one and the same. From the way they look to how they heal, teeth are quite different from the body’s bones.

Bones are still not as strong as teeth!!!

Bones contain calcium, phosphorus, sodium and other minerals, but mostly consist of the protein collagen. Collagen is a living, growing tissue that gives bones their a flexible framework that allows them to withstand pressure. Calcium fills in the space around that framework and makes the bone strong enough to support the body’s weight.

Teeth are composed of calcium, phosphorus, and other minerals. These minerals are arranged in a crystalline pattern as in the enamel making it the hardest substance in the human body.

Bones can regenerate or regrow!!!

The exterior of bones consists of periosteum, a dense, smooth, slippery membrane that lines the outer surface of most bones, except at the joints of long bones, which instead consist of slimy hyaline cartilage. Periosteum contains osteoblasts, or cells that can manufacture new bone growth and repair.

Tooth enamel, unfortunately, doesn’t have the same regenerative powers. Unlike bones, teeth cannot heal themselves or grow back together if they are broken. When a bone fractures , new bone cells rush in to fill the gap and repair the break, but a cracked or a broken tooth can require a root canal or even total extraction.

Bone marrow produces new blood cells!!!

Another difference between teeth and bones is that bone marrow produces red and white blood cells, while teeth do not. Bones receive their blood supply from a number of arteries that pass through the bone’s periosteum to the inner bone marrow.

Although the  core of a tooth that’s been knocked out might look like marrow, it’s actually something called the dental pulp, the living portion of each tooth that contains nerves, arteries and veins and runs through to the jaw bone. The pulp produces cells that can heal the tooth ( dentin in case of a decay )

Bones are not bare!!!

The teeth are bare and on display, while bones are safety covered under our skin.

Bones are for a life time!!!

Bones are formed since birth and they grow was the individual grows older. Humans have two sets of teeth-deciduous or the milk teeth and the permanent teeth that replace the first set of teeth.
