According to research about 95% of the population has some form of malocclusion meaning more or less crooked teeth or the bite is off. Skeletal remains from our ancestors proves only about 5% had the same problem. So why such a drastic difference from way back then to now? Well the answer may be our diets.
The question that is coming up more frequently is can we develop straight teeth naturally without going through braces or Invisalign? Well the answer is unknown, however some evidence suggest that the modern diets we have developed may have a part on how our jaws grow improperly causing are teeth to become crooked. Refined carbohydrates are being explored to be one of the culprits in disturbing normal growth because carbs increases insulin and IGF-1 to abnormal levels. This can cause the jaw to develop narrower. Very little research has been done on this topic however it was discovered that those living in other countries in desolate areas avoided modern foods that contained sugar, canned goods, white flour, and vegetable oils but did consume a diet rich in conventionally prepared foods which included animal fats. These people had wider dental arches, straighter teeth, and little tooth decay.
So in the end will eating a nutrient dense diet make your teeth straight, no one really knows. What we do know though is having diet rich in nutrients is good for strong teeth and bones as well as brain development and without nutrients full development may be interrupted or delayed.
