PFM vs Zirconia Dental Crowns: Which Should You Choose in Juja?

What Is a Dental Crown and When Do You Need One?

A dental crown (also called a cap) is a custom-made cover placed over a damaged, weakened or treated tooth to restore its shape, size, strength and appearance.

You need a dental crown when:

• A tooth is severely decayed and too damaged for a filling alone
• A tooth has cracked or fractured
• A root canal has been performed (the tooth becomes brittle and needs protection)
• A tooth is severely worn down from grinding
• You want to improve the appearance of a badly shaped or discoloured tooth

At Joysmile Dental Clinic in Juja, we offer two types of crowns: PFM (Porcelain-Fused-to-Metal) at KSh 8,000 and Zirconia at KSh 15,000. Here is how to choose.

PFM Crowns: Pros, Cons and When to Choose Them

PFM stands for Porcelain-Fused-to-Metal. This is the most widely used crown type in Kenya and has been the dental standard for decades.

How it is made:

A metal framework (usually a base metal alloy) is cast to fit the tooth precisely. Porcelain is then fired onto the metal surface, giving it a tooth-like appearance.

Advantages of PFM crowns:

• Cost: At KSh 8,000 at Joysmile Dental Clinic in Juja, PFM is the more affordable option.
• Strength: The metal core makes PFM crowns very durable — suitable for back teeth (molars) that absorb heavy biting forces.
• Proven track record: PFM crowns have decades of clinical data supporting their longevity.

Disadvantages of PFM crowns:

• The metal margin: Over time, if the gum recedes slightly, a thin dark line of metal can become visible at the gum line — a cosmetic concern for front teeth.
• Aesthetics: The porcelain on a PFM crown is not quite as naturally translucent as a real tooth or a zirconia crown, especially in bright light.
• Metal allergy risk: Very rare, but patients with metal sensitivities should opt for zirconia.

Best for:

Back teeth (premolars and molars) where aesthetics are less critical and strength is paramount. Also the best value choice when budget is the primary concern.

Zirconia Crowns: Pros, Cons and When to Choose Them

Zirconia (zirconium dioxide) is a high-strength ceramic material used to make all-ceramic crowns without any metal component.

How it is made:

Zirconia crowns are milled from a solid block of zirconia using CAD/CAM technology. The result is a crown that is stronger than PFM and more naturally translucent.

Advantages of zirconia crowns:

• Best aesthetics: Zirconia has a natural translucency very similar to real tooth enamel. Under any lighting, it is virtually indistinguishable from a natural tooth.
• No metal margin: Since there is no metal, there is no dark line at the gum — ever.
• Biocompatible: Zirconia is completely metal-free — ideal for patients with metal allergies or sensitivities.
• Strength: Modern zirconia is actually stronger than traditional PFM — making it suitable for both front and back teeth.
• Less tooth removal: Zirconia crowns can sometimes require slightly less tooth preparation.

Disadvantages of zirconia crowns:

• Cost: At KSh 15,000 at Joysmile Dental Clinic in Juja, zirconia is nearly double the price of PFM.
• Wear on opposing teeth: Very dense zirconia can in some cases cause more wear on the natural tooth it bites against — though modern translucent zirconia has largely addressed this.

Best for:

Front teeth (incisors, canines) where appearance is critical. Also excellent for back teeth in patients who want the best possible aesthetics throughout the mouth, or who have metal sensitivities.
