In a normal, healthy mouth, chewing function is well balanced since each upper tooth has proper contact and function with corresponding lower teeth. Because of this natural proper balance, undue strain or irritation on the gum tissue and bone is non-existent. Drifting or spreading of teeth does not occur and oral hygiene is easily maintained. But, this natural proper balance is quickly destroyed when a tooth is lost.
