So my facial structure has changed since I was a kid because I lost one of my left front tooth, so my jawline is asymmetrical? Will a tooth implant help it form back into a more symmetrical look?

Answer:
Yes, Replacing teeth with dental implants can stabilize the jaw bone preventing additional tooth loss, bone loss, and facial sagging. Dental implant posts mimic the natural tooth root and actually help regenerate healthy bone tissue. Tooth and bone loss can actually change the shape of your facial structure altering your overall appearance.
Explanation:
As your teeth start shifting around or you lose them, that changes the shape and alignment of your jawline. Your jawline starts sagging, and the muscles of your face are unsupported, causing your entire face to start sagging and collapsing, especially the lower half. This causes your jawline to change, which makes you look older. So again, Replacing teeth with dental implants can stabilize the jaw bone preventing additional tooth loss, bone loss, and facial sagging. Dental implant posts mimic the natural tooth root and actually help regenerate healthy bone tissue.
