The size and shape of human teeth has evolved over time, much like other parts of the body. Our ancestors had different weather elements and food types to deal with which required the body to look and respond differently to their particular environment. For example, our ancestors were definitely more hairy than the average person these days because it was a lot colder and their bodies had to adapt to that weather.
When it comes to teeth, they have gone through a similar type of evolution over time. “The researchers analysed tooth size in modern humans, and from fossils of our extinct hominin relatives including the famous Australopithecus afarensis fossil Lucy. They found human teeth appear to follow a rule known as the ‘inhibitory cascade’ – where the size of one tooth affects the size of the tooth next to it. This had been seen in mice previously, but the new research published in the journal Nature shows it also applies to both adult and milk teeth.”
Regardless of how big or small your teeth are they are designed to help you chew your food and smile brightly, but are only able to do so effectively if they are properly being cared for. Make sure to regularly visit your Ottawa dentist for cleanings and check ups.
