A dental bridge is made by using supporting strong, healthy teeth to replace missing teeth. These supporting teeth are called “Abutments”. These teeth are trimmed and made smaller to make the bridge. Some tooth structure is removed in the process and this is a form of damage to a healthy tooth ( Especially to the pulp with the nerves). You can develop sensitivity in the abutment tooth in the long run. Tooth decay under the bridge is also possible, if good oral hygiene is not maintained.
