Crowns are an ideal way to rebuild teeth, which are heavily broken down, weakened by decay/large fillings or root canal treatment.
The crown fits over the remaining tooth to add strength and give it the shape and contour of a natural tooth.
Modern crowns can be made from many different materials. These can be Gold, metal alloys, porcelain or zirconia. They can even be made for a combination of metal and porcelain to provide strength and that natural appearance. There are advantages and disadvantages to each material, which your dentist can go through with you.
Crowns are made of inert materials that do not deteriorate over time. However, the underlying tooth is still prone to decay and gum disease. Ceramic may still fracture on grinding and clenching as well as chewing on particularly hard foods e.g. Ice. Daily brushing and flossing are crucial for preserving good oral health around the crown.
