Dental bridges are designed to replace a missing tooth when there is a healthy tooth on each side of the absent tooth. The best bridges are invisible. They look exactly like natural teeth. The state-of-the-art bridge replacement makes the artificial teeth, positioned in the exact place where teeth are missing, with the same color as natural teeth. Bridges are very important in helping to maintain the current tooth position as teeth can begin to shift when the gap in between would extend for some period of time.
