With the loss of teeth, several changes immediately begin in the jaw bone. Existing teeth may start to shift toward the void of space in the jaw. Movement of dental structures can create misalignment, affecting the bite and uniformity of teeth.  

Bone loss begins within the first year of a person losing a tooth. Without teeth, the roots are not able to stimulate the jaw bone to regenerate. The loss of pressure on the jaw from chewing weakens the bone, and the bone begins to atrophy.     

Jawbone deterioration is called resorption, and this can jeopardize the health of other teeth. Resorption also changes the facial structure, giving the mouth a sunken appearance that adds years to your smile.
