Do you need a crown or another filling?

The short answer
A filling repairs a localized defect; a crown covers a tooth when the remaining structure needs greater protection. The decision depends on how much sound tooth remains, where it is weakened, and how your bite loads it. A large filling alone does not automatically mean every tooth needs a crown.
A cusp is a raised part of the chewing surface. When decay or an old restoration leaves a cusp poorly supported, covering the tooth may protect it better than replacing only the missing material. The examination should establish whether the tooth can be restored and whether a crack or another problem changes the plan.
Crowns require tooth preparation, so it is reasonable to ask why that additional treatment is needed. A useful explanation identifies the weak area and the limitation of a smaller restoration. Ask the dentist to show the finding with an image or mirror where possible. Also ask whether an onlay, a restoration covering part of the chewing surface, is an appropriate alternative in your case.
For a Duluth crown consultation, bring any recent treatment plan and explain whether the tooth hurts on biting, reacts to temperature, or has lost a piece. Request the recommended restoration and its alternatives in writing. If the tooth is symptom-free, the explanation should still address its structural condition. If it is painful, the appointment needs to investigate the cause rather than assume that a crown alone will resolve it.
