A porcelain-fused-to-metal (PFM) crown combines a metal alloy inner cap with an outer layer of tooth-coloured porcelain, delivering a balance of structural strength and acceptable aesthetics that has made it the most widely placed crown type for decades. The metal substructure provides robust support, especially for back teeth, while the porcelain overlay blends with surrounding natural teeth. PFM crowns are a cost-effective, well-proven option with a long clinical history and predictable longevity of 10–15 years.
Your dentist examines the tooth, takes X-rays, and determines whether a PFM crown is the optimal restoration given the tooth position and bite forces.
Under local anesthesia, the tooth is reshaped to create space for the crown. Slightly more enamel is removed than for all-ceramic options to accommodate the metal substructure.
A precise impression or digital scan of the prepared tooth is taken and sent to the laboratory. A temporary acrylic crown protects the tooth during fabrication.
The dental technician casts or mills the metal coping, then layers and fires porcelain to achieve the desired shape and shade.
The crown is placed on the tooth to verify the fit, check the bite, and assess the shade match before final cementation.
The PFM crown is permanently cemented with a dental luting cement, excess is removed, and the margins are polished.

Healing
Consultation, X-ray review, local anesthesia, tooth reshaping, impression or digital scan, temporary crown placed.
Metal coping cast or milled; porcelain layered, shaped, and fired to achieve final shade and form. Typical turnaround 3–4 working days.
Try-in for fit and shade check, bite adjustment, permanent cementation, margin polishing.
The metal substructure makes PFM crowns highly resistant to fracture under occlusal loading, particularly on molars.
PFM crowns are significantly less expensive than full zirconia or E-max alternatives while still providing excellent function.
Suitable for any tooth in the mouth, including high-load posterior teeth where all-ceramic crowns may carry fracture risk.
The porcelain exterior can be shade-matched to neighbouring teeth for a natural appearance in most clinical situations.
PFM crowns have been in clinical use for over 60 years with extensively documented long-term success rates.
As the gumline recedes naturally with age, the metal margin may become visible as a dark line at the gumline — a common cosmetic concern with PFM crowns.
The porcelain veneer layer can chip or fracture under heavy impact. Chips on posterior crowns are often not visible; anterior chips may affect aesthetics.
Slightly more natural tooth structure must be removed compared to all-ceramic crowns to accommodate the combined metal and porcelain thickness.
Rarely, patients with nickel or cobalt sensitivity may react to the metal alloy. A precious metal alloy or all-ceramic alternative can be used instead.
Avoid sticky or very hard foods while the cement fully sets. Bite carefully to avoid dislodging the crown before complete adhesion.
Brush the crown and margin twice daily using fluoride toothpaste. Pay particular attention to the gumline where the crown meets the tooth.
Floss daily around the crown, threading floss carefully under the contact. A floss threader or interdental brush helps clean the margin effectively.
Do not bite hard objects such as ice, nutshells, or pen caps, which can chip the porcelain surface.
See your dentist every 6 months for professional cleaning and margin inspection to detect any early issues with cement seal or gum health.
A PFM crown typically requires two appointments over 4–5 days, making it ideal for a short dental tourism trip to Eastern Europe. Tooth preparation on arrival day, crown delivery before departure.
