Many people think that tooth and bone are the same – they are both hard, white and contain calcium. However, scientists confirm that a tooth is fundamentally different from a bone, although appearances can be deceiving. A tooth is not considered part of the skeletal system, and its structure and function are completely different. Understanding the differences is important not only for fun facts, but also for knowing how to properly care for your oral health.
Why is a tooth not a bone?
The main difference between tooth and bone is their purpose. Bones support the body, protect internal organs, allow movement and even produce blood cells. Meanwhile, the tooth is a specialized organ for chewing and preparing food for digestion and helps in making sounds.
Bones are living, constantly renewing tissue, while teeth are not. It cannot repair itself, so any damage to the enamel is irreversible. This is one of the main reasons why oral hygiene is so important.
Tooth Structure: What’s Inside?
Many people don’t know that teeth are made up of several layers and not just a hard surface. Its upper part is enamel, the hardest substance in the human body. Beneath it lies dentin, a slightly softer layer with microscopic tubules containing nerve endings. Deeper is the pulp, a soft tissue with nerves that gives the sensation of pain if the tooth is damaged.
This complex structure explains why the tooth is so susceptible to damage and why it is necessary to visit the dentist as soon as discomfort occurs.
Bone structure: living and constantly regenerating tissue
Unlike teeth, bone has blood vessels and nerves both inside and outside. It is covered with a thin layer – the periosteum, which hides strong compact bone tissue and an inner porous layer with bone marrow. This unique structure allows the bone to heal and regenerate – the entire human skeleton practically regenerates in about 10 years.
Why is it important to take care of your teeth?
Since teeth cannot regenerate their outer layers, it is important to take care of your mouth daily: brush your teeth twice a day, floss, limit sugar and visit your dentist regularly. New research shows that certain substances, even found in human hair, can help protect tooth enamel even more effectively than fluoride – leading to even more innovative toothpastes in the future.
