Gold crowns are not a very popular choice among patients as it does not have much aesthetic appeal. They are suitable for patients who are in the habit of biting strong food substances along with clenching and grinding.
Gold crowns offer increased durability and are suitable for the back teeth like the molars so that they are not visible.
Forms of Gold crownsGold crowns are available in three forms:
Gold crowns are a comfortable and safe option to choose as it is very compatible with the interiors of the mouth. The chances of allergic reactions are minimal in this case.
Gold restorations last for up to 20 to 40 years.
Another important advantage of using gold for crowning is that the rate at which gold contracts and expands is similar to that of natural tooth. This prevents the gold from cracking, chipping and breaking away from the tooth. Also, the smoothness and purity of gold is commendable and does not stain or darken over time.
The fitting that a gold crown provides is better as compared to the porcelain ones and this is also the reason for its long life. Gold crowns do not undergo fractures like the porcelain crowns. A major disadvantage of porcelain crowns is that they scrape the opposite teeth faster than a natural tooth but gold does not do so. Again, gold is a metal which is very smooth as compared to other metals. Porcelain crowns are rough and bacteria added food particles can easily stick to it increasing the chances of infections but gold can be cleaned easily.
Tissues surrounding a gold crown stay healthier as compared to porcelain as irritation and sensitivity is minimized. This becomes beneficial as one ages.
