A crown protects and restores
A crown may be recommended for a tooth with substantial damage, a large restoration or a need for protection after treatment. The dentist evaluates the remaining tooth, gum health and bite before deciding whether a crown is appropriate.
Ask whether a smaller restoration is possible and what the preparation involves. If a temporary crown is used, follow instructions for eating and cleaning, and contact the office if it loosens or breaks.
A bridge spans a missing-tooth space
A traditional bridge uses neighboring teeth for support. Other designs may use implants or different attachment methods. The condition of the supporting teeth, size of the gap and bite influence the recommendation.
Discuss alternatives such as an implant or a removable appliance. Ask how the teeth beside the gap will be affected and what treatment would involve if a supporting tooth later develops a problem.
Cleaning is part of the design
A bridge needs cleaning underneath the replacement tooth as well as around its supports. Ask the team to show you an appropriate flossing aid or interdental cleaner before you leave.
Neither a bridge nor crown prevents decay in the remaining natural tooth or disease around the gum. Keep regular visits and report discomfort, a changing bite, a loose restoration or food collecting in a new place. Ask about expected maintenance and possible replacement over time.
