Before that, there were metal dental crowns made of animals tissue, ivory and pure gold. Later in the early 1900s jacket crowns were also introduced but failed to gain popularity.
What are the benefits of Metal Dental Crowns

They are very strong, have high flexural strength and can resist very high and rough chewing forces even the night clenching. This is the reason they don't get fractured easily.
2. Durable:
They last a long time without getting worn down or chipped.
3. Easy to maintain:
Metal crowns have a shiny surface which keeps stains, debris and scratches at bay. They are easy to clean and maintain.
4. Minimal Tooth Preparation:
Metal crowns have thin borders and margins. So, in a way they save the tooth structure from getting trimmed. This conservative nature is highly appreciated.

Type of metal crowns
The type of metal crowns varies according to its usage, indications, & patient.
According to the material;
Only metal crowns: These metal crown tooth caps are made of only metal alloys like gold, nickel, palladium or combined metal alloys.
Porcelain fused to metal: In this type of metal ceramic crown, on the outer side of metal crown tooth shaded porcelain is attached or fused. Metal-ceramic crown is made ato obtain a better appearance at an affordable price. On the cons side, with time the porcelain is damaged, and the inner layer of metal is exposed leaving a black line over gingiva.
PFMs are the most popular crowns because they are aesthetic and also affordable.
According to Age
In children: Usually, children are prescribed to go for metal crowns or premade metal teeth caps because they are thin, ready to restore, and do not need tooth preparation.
In adults: there are some cases where metal crowns are suggested like;
- Extensive damage to teeth
- Where aesthetics is not a concern for the patient like in molars
- The patient doesn’t want to spend much on ceramic crowns
Disadvantages of Metal Crown
These crowns are not that good when speaking about aesthetics, let’s discuss some more challenges that may come over with time.
- Leaching ions: Metal alloys leach out ions that may cause allergies and tissue discoloration.
- Interference: Metal crowns may interfere with MRI or XRAYs and even security scannings.
