The roots of teeth serve multiple functions, but two of the most basic are holding a tooth in place and sending signals to your body that support, by way of bone, is needed in a specific area. When a tooth and its root are lost, these signals cease, eventually allowing your body to reabsorb the bone and alter the structure of your face.
Once inserted, Austin dental implants undergo a process known as osseointegration in which they become accepted as a new tooth root. This allows signals to remain between the new root and your body, preventing jaw shrinkage and collapse.
