The jaw bone irreversibly changes if a tooth is lost or extracted and it not replaced with an implant. Without chewing pressure to stimulate the bone, it begins to dissolve away the bone – a process called resorption.
In addition to bone loss, there is also shifting of the adjacent teeth towards the vacant space. Over time, this will create gaps between the other teeth in other parts of the jaw.
When teeth are missing, the teeth on the opposing jaw have no counteracting force and will shift towards the vacant space. This will affect the general anatomical orientation of teeth and can limit what and how you can eat.
The deterioration of the jaw bone affects the appearance of the face. This can make one look older with more non-age related wrinkles, which can reduce confidence leading to a change in one’s lifestyle.
