If poor orthodontia causes so many health problems, why didn evolution/natural selection eliminate orthodontic problems?
According to Alex Duncan of the Anthropology Department at the University of Texas, “with very few exceptions, fossil hominids (cave men) had nearly perfect bites.” Malocclusions (overbites and underbites) developed mainly over the last 10,000 years. As medicine and diets improved, people grew taller. The average height of an adult male increased from 4 ft (1.2M) 10,000 years ago to about 5ft 9 in (1.75M) today. Human mouths and human teeth did not grow at the same rate. In many cases your child’s teeth will be larger than your child’s mouth.

As peoples diets improved, people got bigger. The average height of an adult male increased from 4 ft (1.3M) 10,000 years ago to about 5 1/2 feet (1.9M) today. Human mouths and human teeth did not grow at the same rate. In many cases your childs teeth will be larger than your childs mouth. If so, your child will need orthodontic treatment. It has been estimated that in modern man, about 70% of the general population needs orthodontic treatment. • If orthodontic problems are caused by my childs teeth being too big for their mouth, will my child grow out of it? Unfortunately no. Remember that your child’s permenant teeth do not grow in all at once. As your child’s mouth grows, more permenant teeth grow in too. The additional teeth take up all
Hmm. We do not know. It has been said that if babies use a pacifier (dummy) for too long, they can develop an orthodontic problem. Orthodontic problems can also be caused by injuries to your mouth, or if you suck your thumb when you are older than two. Some orthodontists also say that fingernail biting, or lip biting can also cause orthodontic problems. Still, most people develop orthodontic problems because their teeth grow faster than their mouth.
