Once a tooth is lost, the bone in that part of the jaw dissolves back into the body. This is a natural process that is brought upon by the lack of stimulation that your jawbone receives. However, this will reduce the height and depth of your alveolar ridge, the bony ridge that supports your teeth and will make your facial features sag. Using other tooth replacement options like dental bridges and dentures is not enough to prevent jawbone loss. That is why we strongly recommend you get dental implants once you lose your teeth.
