Like natural teeth, dental crowns need daily cleaning. The durability of a crown also depends on how the tooth is being used, but generally a crown can be expected to last for 10-15 years. Most often, troubles with crowns are caused by caries in the tooth. Therefore, it is very important to use toothbrush and dental floss every day.
Crowns are sometimes chosen over extensive fillings as a more durable solution. Large fillings can cause breakage in the natural tooth. Moreover, fillings of this size can irritate the nerve, leading to inflammation and possibly need of root treatment.
Another alternative to crown treatment is to have the tooth extracted. However, if the tooth is not replaced by implants, the surrounding teeth will begin to move towards the empty space. This can lead to a crooked bite.
