What Teeth Can Tell Us

We all know that our teeth are important for eating, but what other function do they have aside from talking and eating? 

You may not realize this, but your teeth can tell people a lot about you. In fact, by examining your teeth, forensic dentists can learn critical information about your origins, dental health problems and lifestyle choices.  

This post will explore some fascinating facts that can be determined from a teeth examination!

Facts that can be determined by the examination of the teeth

What can a teeth examination tell us? Quite a lot, as it turns out. By performing an examination of our teeth, dentists can extract a wealth of information from them, some of which include:

Age: One of the first things teeth can tell us is a person’s age. This is because our teeth go through a predictable process of growth, development, and wear as we age. Dentists can use this knowledge to estimate how old a person is within a certain margin of error.

Ethnicity: Teeth can also tell us about a person’s ethnicity. For example, people from East Asia tend to have smaller teeth than those of European descent. This is because the two groups evolved under different environmental pressures.

Gender: Teeth can also indicate a person’s gender. For instance, men generally have thicker, more rugged enamel than women. This is because men are generally subjected to more wear and tear due to their activities.

Diet: The foods you eat can affect your teeth in many ways. For example, if you eat a lot of sugary foods, you’re more likely to develop cavities. However, if you eat a lot of acidic foods, you may be at risk for enamel erosion. And if you eat a lot of staining foods (like coffee or tea), your teeth may become discolored over time.

Lifestyle choices: Our lifestyle choices can also be reflected in our teeth. People who smoke tend to have more yellow teeth than non-smokers due to the chemicals in cigarettes that stain their teeth. Similarly, heavy drinkers often have less-than-perfect teeth due to the high sugar levels in their diets. While people who use drugs may have needle marks on their gums from injecting drugs.

Identity Resolution: Teeth can be used to identify individuals since each person’s teeth are unique. Researchers examine a variety of factors in order to determine whose mouth they’re looking into. 

These factors include things like the number of teeth there are, the kinds of teeth (deciduous “baby” teeth or permanent “adult” teeth), tooth positions and orientations, tooth forms and sizes, as well as traces of diseases or dental treatments such as fillings or braces.

 This comprehensive description can then be compared with dental records from doctors to determine the person’s identity

Health conditions: Finally, teeth can also give us information about our health. For example, people with diabetes are at an increased risk of developing gum disease. This is because the high levels of sugar in their blood can damage the tissues in their mouths.


In conclusion, teeth can offer a lot of information about a person. Dentists can learn about our age, ethnicity, gender, diet, lifestyle choices, and even health conditions by examining our teeth. This information is invaluable, both for personal and forensic reasons. 

So, ensure you keep your teeth healthy and get them checked by a dentist regularly. Doing this can help you identify oral health problems early on before they lead to more serious issues.
