Made of a ceramic substance like porcelain, ceramic crowns are white and quite hard, making it an apt choice for a dental crown. A ceramic crown could either be a pure ceramic crown or a porcelain-fused metal crown. Porcelain crown looks natural with no metal present on the teeth. Whilst it may not be as strong as its alternatives if you want a natural look go with it after consulting a dentist.
2) Stainless steel dental crown
Usually used by prefabricated methods, they are used mostly temporarily. Whilst the permanent crown is made of some other material, they are used mostly as a stop-gap measure. Apt for children, they are very cost-effective and don’t require multiple dental visits to be placed in the tooth. Usually, they are used to repair decayed molar teeth/preventing teeth from decaying further.
3) Gold alloy dental crown
Gold alloy dental crown can be either made completely of gold/mixture of gold with other metals. This type of dental crown has been used for a long time and the main subcategories in a gold alloy dental crown are:
- High noble alloy(minimum 60% alloy – made of gold, platinum and palladium)
- Noble alloy

- It can withstand heavy forces when you chew.
- They are long-lasting and formidable.
- They are excellent at restoring molars and pre-molars.
4) Base metal alloy dental crown

Whilst the costs are considerably lower when compared to the gold alloy crown, it is more likely to corrode when compared to its gold alloy alternative due to the high concentration of non-alloy materials. To speak about the pros, base metal alloy crown is quite strong and can reasonably thwart corrosion to a great extent.
