10 things you probably didn’t know about teeth

Teeth are an essential part of the human body, helping us to bite, chew, and speak. While many people know the basics about teeth, there are plenty of interesting and lesser-known facts that are worth exploring. In this blog post, we will take a look at 10 fascinating and lesser-known facts about human teeth.

Teeth are Not Bones

While teeth may look similar to bones, they are actually different structures. Bones are made up of living cells, while teeth are composed of different layers, including enamel, dentin, pulp, and cementum.

Teeth Can Repair Themselves

Unlike bones, which can only heal through the growth of new tissue, teeth can actually repair themselves to some extent. This process is known as remineralization, and it occurs when minerals in saliva are deposited back into the teeth.

Teeth are Unique Like Fingerprints

Just like fingerprints, teeth are unique to each individual. This is why dental records are often used in forensic investigations to identify victims or suspects.

Teeth Can Reveal Information About Diet and Health

Teeth can reveal a lot of information about a person's diet and health, including the types of foods they eat and whether they have certain health conditions such as diabetes or anaemia.

Baby Teeth Have a Purpose

While many people think of baby teeth as temporary placeholders, they actually serve an important purpose. Baby teeth help children to speak clearly, chew food properly, and guide the permanent teeth into place.

Teeth are Stronger Than You Think

Despite their small size, teeth are incredibly strong. In fact, the force of a single bite can exceed 200 pounds!

Saliva is Important for Oral Health

Saliva plays an important role in oral health by helping to neutralize acids in the mouth, prevent tooth decay, and aid in digestion.

Teeth Can be Sensitive to Temperature

Many people experience tooth sensitivity when eating or drinking hot or cold foods. This is because the nerves in the teeth are exposed and can react to changes in temperature.

Teeth Can Absorb Colours

Certain foods and drinks, such as coffee, tea, and red wine, can stain teeth over time. This is because the enamel on the teeth is porous and can absorb colours.

Brushing Too Hard Can Damage Teeth

While brushing your teeth is important for oral health, brushing too hard can actually cause damage to the enamel and gums. It's important to use a gentle brushing motion and a soft-bristled toothbrush to avoid causing harm.


Human teeth are complex structures with many fascinating features and functions. From their ability to repair themselves to the unique patterns that make them as individual as fingerprints, there are many lesser-known facts about teeth that are worth exploring. By taking good care of our teeth through proper oral hygiene and regular dental checkups, we can ensure that they continue to serve us well throughout our lifetime.
