When your tooth is compromised to the point where much of it is missing, a crown is fixed to the remaining tooth structure to restore the original shape and appearance.
Teeth may be broken down due to fractures, dental decay or wear. If large fillings are present, then a tooth becomes more likely to fracture and a crown may be suggested.
Following a root canal treatment the tooth will be filled with a temporary filling. A crown is recommended to strengthen the remaining tooth to prevent a fracture and further tooth loss. If your dentist notices a significant tooth fracture they will likely suggest a crown to protect the remaining tooth structure preventing future damage.
Crowns completely surround the remaining tooth, making an effective structural brace that makes the resulting tooth/crown combination stronger than the damaged tooth.
Crowns can also be placed for cosmetic reasons. Teeth that are worn down, have bad colour or are heavily filled may be improved with a crown. As the crowns cover the old tooth completely, they can drastically improve its colour and shape, offering huge benefits in improving your smile. When you come for a hygiene appointment, the hygienist will be able to see if any of the above damage has occurred to your teeth. When the dentist does your exam he will review your X-rays and suggest if a crown is recommended or not.
