A dental bridge uses two crowns on neighboring teeth to support an artificial tooth known as a pontic. Dental bridges are more affordable than implants and they do a decent job of filling in the gap, but there are a few drawbacks to this treatment option. For starters, some tooth material will need to be removed from the neighboring teeth in order to fit the crowns of the bridge. Therefore, those teeth will always require crowns, even if you later decide to have an implant placed. Secondly, if you are replacing a molar or pre-molar, the restoration may not be strong enough to chew hard, crunchy foods. This means you may be left to chew foods on the side opposite your dental bridge. Chewing on one side only can cause uneven wear patterns which may lead to complications down the road, including temporomandibular joint disorder (TMJ).
One other detracting point on bridges is that they can cause the gums to recede, which can cause the metal base or collar to become visible.
