The decision rule of thumb

• Filling: Small–moderate cavities/chips where enough strong tooth remains.


• Crown: Large fractures, multiple cracked cusps, or after root canal—when we need 360° protection.

Why it matters

Undertreating a weakened tooth can lead to new cracks and emergency visits; overtreating removes unnecessary tooth. The goal is conservative strength.

How we decide

Exam, bite analysis, history (clenching/grinding), and imaging help us judge remaining tooth structure.

Cost & durability

Fillings are more conservative and cost less; crowns last longer in high-stress situations.

FAQ

Can a big filling be upgraded later?

Yes, but cracks can develop—timing matters.

Do crowns look natural?

Modern ceramics match colour and translucency.

Do crowns whiten?

No—whiten first, then match shade.
