Crowns & Onlays
Do I really need a dental crown?
A crown can be the right choice when a tooth is heavily filled, cracked, or at high risk of breaking—but it isn’t always the only option. In many cases, an onlay, partial coverage restoration, or even monitoring may be appropriate. The key is understanding what risk we’re trying to reduce, and whether a less invasive option can protect the tooth long-term.
Why this is recommended sometimes
Crowns are often suggested when a tooth has:
- a large filling that leaves the remaining tooth weak
- cracks or fracture lines
- root canal treatment (sometimes)
- repeated breakage or symptoms on biting
Common alternatives
Depending on the tooth and bite, alternatives may include:
- onlay or partial coverage restoration
- bonded composite build-up
- night guard + monitoring (for cracks/grinding)
- doing nothing for now, with clear review points
Risks & long-term considerations
- tooth preparation is irreversible
- risk of sensitivity or nerve irritation
- crowns may need replacement in the future
Questions to ask your dentist
- What is the main risk you’re trying to reduce?
- Can we consider an onlay or partial coverage?
- What happens if we wait 6–12 months?
When to seek urgent in-person care
If you have severe pain, swelling, fever, trauma, or difficulty swallowing/breathing, seek urgent care.
