When a filling is no longer enough
A filling replaces missing tooth structure from within. Once too much structure is lost, the remaining walls of the tooth become vulnerable to flexing and fracture under biting force. A crown covers the tooth so that force is distributed over it rather than through weakened walls.
This is why crowns are commonly recommended after root canal therapy and for teeth with large, repeatedly repaired fillings.
Bridges versus implants
A conventional bridge spans a gap using the teeth on either side for support. It is a well-established solution and can be completed relatively quickly, but it requires preparing those adjacent teeth.
An implant replaces the missing tooth independently and leaves neighboring teeth untouched, though it involves surgery and a longer timeline. Where the adjacent teeth are already heavily restored, a bridge may be sensible; where they are pristine, an implant is often the more conservative choice overall.
What determines longevity
Fixed restorations usually fail at the margin, where the restoration meets the tooth.
- Accurate fit and well-finished margins
- Daily cleaning at the gum line and beneath a bridge
- Control of grinding forces
- Regular review so early problems are caught
Materials are chosen by role
A front tooth restoration needs to reproduce translucency and subtle shade variation. A molar restoration needs to withstand substantial force. Modern ceramics can often meet both demands, but selecting the right material for the position is part of the clinical decision.
