A "crown" sounds dramatic, but it is one of the most common ways to save a tooth that has been damaged, repaired multiple times, or treated with a root canal. This guide walks through when a crown is the right call, the materials commonly used, and how long crowns typically last.
What a crown actually is
A dental crown is a custom-made "cap" that covers the entire visible part of a tooth. It restores shape, strength, and appearance. It is bonded or cemented to the remaining tooth structure underneath.
When you actually need one
- After a root canal, to protect a tooth that has become more brittle
- When a tooth has a large filling that is at risk of cracking
- To repair a tooth with a visible crack or broken cusp
- To finish a single-tooth implant
- To anchor a bridge on either side of a missing tooth
- For cosmetic reasons when a tooth is deeply discolored or misshapen and a veneer is not enough
Crowns are not always the right answer. Small chips and gaps often do better with Bioclear or bonding. Smile changes across several teeth may be better suited to veneers.
Materials to ask about
Three families come up most often:
All-ceramic (zirconia or lithium disilicate). Strongest modern options, look very natural. Most dentists use these as the default for back and front teeth today.
Porcelain fused to metal (PFM). Long history of use; a metal core under porcelain. Strong, but the metal margin can show as a gray line at the gumline over time.
Gold or other metal alloys. Extremely durable, gentle on the opposing tooth, but visible. Most common in molars where aesthetics matter less.
Your dentist will recommend material based on which tooth it is, your bite, and the look you want. For front teeth, a layered ceramic that mimics natural translucency is usually the goal.
What getting a crown involves
Two-visit process at most offices:
- Visit 1: numbing, gentle shaping of the tooth, digital scan or impression, temporary crown placed
- 1 to 3 weeks: lab makes the final crown
- Visit 2: temporary off, fit and bite check, permanent crown bonded
Some practices offer same-day crowns milled in-office. Both approaches can produce excellent results; the right choice depends on the case and the materials needed.
How long crowns last
Modern ceramic crowns commonly last 10 to 15 years and often longer with good home care. Lifespan depends on:
- How much healthy tooth was left under it
- Your bite forces and whether you grind at night (a custom night guard helps)
- Gum health (recession exposes margins to decay)
- Diet and habits (ice chewing, opening packages with teeth)
Crown work at Dental Salon is delivered at both Lincoln Park and Schaumburg. See our dental crowns page for the full process.
Frequently asked questions
Will I feel anything during the procedure?
The tooth is fully numb. Most patients feel pressure and vibration but no pain. Sedation is available for longer cases or dental anxiety.
Will the tooth be sensitive afterward?
Mild sensitivity for a few days to a couple of weeks is normal. If sensitivity is sharp, lingering, or worsens, call the office for a bite check.
Can a crown get a cavity?
Not the crown itself, but the natural tooth at the gumline can. That is why daily flossing and regular checkups matter.
Will insurance cover a crown?
Most PPO plans cover crowns when they are medically necessary (decay, fracture, after root canal). Purely cosmetic crowns are usually not covered. See our insurance page.
