What Determines the Position of Your Teeth
Our teeth grow and develop in response to the balance of forces in our bite. Just as the way teeth fit together influences the way our bite works, so, the way our bite works will influence the way our teeth come in.
Our teeth are naturally subjected to forces in four directions. They are pushed up or down by forces driving them out of the jaw. They are pushed in the opposite direction by forces from opposite teeth. They are pushed outward by the tongue and inward by the cheeks.
But these forces can be changed by a number of different factors that influence how our bites develop.
Archaeologists were surprised to find that prehistoric people had different bites than modern humans. Instead of having an overbite, they had teeth that met edge to edge in the front of the mouth. This produced teeth that strongly contacted one another.
The benefit of this is that it made it easy for prehistoric people to bite off and tear foods. The disadvantage of this is that it led to much more wear on their teeth. Most prehistoric people had their teeth severely worn down by what we would consider a relatively young age. By the time they reached their 30s, their teeth would be worn as much or more than a 60-year-old today.
As their teeth wore down, they became super-erupted, which means that much of the root had emerged from the jawbone.
Where Did Our Overbite Come from?
So if people naturally have an edge-to-edge bite, why did we develop an overbite that is common to practically every man, woman, and child in the US, Europe, and across Asia?
There are a lot of theories about this, but the one that’s current today is that the fork is responsible.
The theory is that when people began cutting their food into small pieces and eating it with a fork, the forces that control the emergence of our teeth are changed. Biting and tearing a steak places force evenly on the upper and lower teeth, but eating from a fork puts more outward force on the upper teeth, which pull the food off, than the lower teeth, which don’t participate. The repetition of this force multiple times a day for a lifetime causes the difference.
This theory is supported the fact that forks were introduced and overbites developed at the same time. The theory also gets support from the fact that the transition occurred about 900 years earlier in Asia, corresponding to the introduction of the chopsticks.
