Dental crowns, are permanent prosthetics cemented onto teeth or implants. They strengthen damaged teeth, improve appearance and bite, and prevent shifting. Crowns cover most of a tooth’s exposed part and resist decay, though decay can still occur at the gum line.
Process:
First, the dentist checks and shapes the tooth; if needed, they restore the base. An impression is sent to a lab for the permanent crown, and a temporary crown is fitted. At your next visit, the permanent crown is cemented in place.
Porcelain Fused to Metal (PFM) Crowns:
These crowns have a metal base with porcelain fused over it, delivering durability with a natural look. PFM crowns from Amazing Dental Care contain nickel, so inform your dentist of any allergies.
| Advantages | Disadvantages |
|
PFMs ensure a precise fit and are durable even if the porcelain layer chips. The metal substructure keeps the tooth protected. |
Aesthetic limitations make PFMs less suitable for highly visible teeth; zirconia may be preferred for appearance. More tooth must be trimmed compared to zirconia options. Potential for metal allergy and corrosion. |
Adjustment
Mild discomfort or sensitivity after placement is normal and should fade within weeks.

Zirconium Crown (Zr)
Zirconia (zirconium oxide) is a white powdered metal commonly used for dental frameworks such as crowns, bridges, and other dental substructures. It provides a whiter, more translucent appearance to teeth and is transparent on x-rays. Zirconia has been utilised in cosmetic dentistry for several years to achieve aesthetic results, and it has more recently become a widely accepted dental material. Zirconia crowns are suitable for molars due to their strength and also maintain the desired appearance for front teeth.
| Aspect | Description |
| Translucency | Zirconia crowns can be sufficiently translucent to blend with natural teeth, offering a realistic look. |
| Gum Margin Appearance | When bonded rather than cemented with conventional dental cement, these crowns do not display a visible line at the gum margin. |
| Damage Resistance | Porcelain crowns may chip, while zirconia crowns demonstrate increased resistance to damage. |
| Material Durability | Zirconia crowns are fabricated from durable materials intended for long-term use. |
| Strength & Tooth Preservation | They provide significant strength with reduced volume compared to some other crown materials, which may allow preservation of additional healthy tooth structure in limited spaces. |
| Biocompatibility | Zirconia is considered biocompatible, making it unlikely to cause allergic or adverse reactions. |
| Corrosion Resistance | The material is resistant to corrosion, contributing to its overall durability. |
| Friction | Zirconia crowns can create friction with adjacent teeth and the tooth root due to their hardness. |
| Decay Risk | Decay beneath a crown can loosen or dislodge it, so maintaining good oral hygiene remains important. |
Adjustment Period
It is typical for a newly cemented crown to feel different for several days as adjacent teeth adjust to altered biting forces.
