Why Do We Have Two Sets Of Teeth?

Have you ever wondered why we have two sets of teeth? At around 6 or 7 years old, our baby, or milk teeth, start to loosen and eventually fall out. This is a natural process and soon new teeth replace the ones that fall out. The baby teeth actually help in making sure that the “permanent” teeth erupt in their natural spot.Lower organisms on the evolutionary chain that have teeth can sometimes develop new teeth throughout their lifespan. The teeth of these species are usually designed for slashing, while the teeth of higher life forms are designed for chewing.Human baby teeth stimulate and guide the development of jawbones and permanent teeth. This means that even though the teeth are “temporary”, they are still important and should be taken care of. A theory exists indicating a child’s teeth would be too small for an adult mouth, hence the need for the smaller teeth to be replaced with larger teeth. There are normally only 20 baby teeth compared to 28-32 adult teeth. Gentle Dental recommends that you assist a child into developing good hygiene habits early.
