A crown, or cap, fits over the remaining part of a prepared tooth, giving it the shape of your natural teeth and making it stronger. It protects a broken, weakened or heavily filled tooth and can also be used to improve the appearance of discoloured or crooked teeth. In modern-day dentistry. there is a wide variety of dental materials to choose from. All-porcelain or -ceramic crowns are the best choice for a natural cosmetic look. Dental crowns require the same level of care and attention as your natural teeth. Provided you have a good oral hygiene program, attend regular checkups at your dentist, don’t grind your teeth, maintain a tooth-kind diet, a high-quality dental crown can last 10-15 years.
