Tooth loss is not the only tooth lost.
It is known that the physical forces transmitted to the teeth by chewing have the effect of stimulating the presence of the jawbone and creating cell regeneration. The jawbones that support the teeth can be adversely affected if the teeth are pulled out, and since the physical forces directly transmitted to the bone are eliminated, melting can be seen in the jawbones. In natural bone formation and destruction physiology, the upper jaw bones melt from front to back and the lower jaw melts from back to front. This situation, in which people’s lower jaw moves forward due to aging, is observed much more clearly especially in people with tooth deficiency.
