When a tooth is lost the bone around the area of the missing tooth rapidly disappears in the first year. The bone will continually disappear year after year. Chewing creates tremendous pressures and forces that the teeth share. When one or more teeth are missing the remaining teeth are forced to handle the excessive forces. This can cause many problems such as teeth breaking, shifting teeth, altered chewing and headaches. Teeth will shift and move into the missing spaces creating more problems than just the missing tooth.
