When is a crown better than a filling?

When too little healthy tooth remains to support a filling, when cracks threaten cusps, or after root canal treatment on back teeth. Your dentist should explain the structural reason.

Can I get a second opinion on a crown?

Yes — and it is reasonable for expensive treatment. Bring X-rays and the written treatment plan.

How long do crowns last?

Often 10–15+ years with good hygiene and night-guard use if you grind. Lifespan varies by material, bite, and maintenance.

Do crowns require two visits?

Traditional crowns often do (temp, then permanent). Same-day CAD/CAM crowns can finish in one visit at equipped practices.
