When teeth are missing, your smile undergoes significant changes. Missing teeth cause you to chew differently, may cause mouth pain, and as your remaining teeth work to compensate for the loss, gaps and spaces form that only make the situation worse. A porcelain bridge, custom designed by your doctor, keeps your smile aligned and your bite functional. Bridges are anchored to existing teeth or crowns on either side of the missing tooth. They are semi-permanent, meaning they can only be affixed or removed by a dentist and are a long-term restorative solution to your damaged smile.
