Tooth loss or extraction leaves a space between teeth that may cause problems if allowed to remain. When teeth are removed, the supporting bone tissue shrinks over time. Resorption of the alveolar bone that supports teeth begins almost immediately after extraction. If you lose multiple teeth, significant bone loss may occur, and this can affect your appearance and your ability to wear dentures. Other problems related to tooth loss include drifting of your other teeth and an increased risk of tooth decay and gum disease. Fortunately, if you’re missing one or more teeth, you may have several options for tooth replacement.
