Crowns are used when a tooth becomes heavily decayed, damaged, or cracked, and a filling is no longer enough to restore the tooth. Crowns serve as a permanent cover for the tooth, to save it from further damage and prolong its life.
Situations a crown be may required are: broken or fractured teeth, cosmetic enhancement, heavily decayed teeth, fractured fillings, large fillings, and root-canal treated teeth.
Crowns can be made of a variety of materials such as porcelain, gold, acrylic, or a mixture of these materials. However, porcelain is the most popular material for crowns and it most resembles your natural teeth. The crown will me made to match the shape, size, and colour of your teeth to give you a natural, long-lasting, and beautiful smile. Porcelain crowns are highly durable and will last many years, though may need to be replaced eventually, like most dental restorations.
A crown usually requires two appointments. The first will include preparing the tooth and taking several molds or digital impressions that will then be used to create your own custom crown. At the second appointment, your new crown will be carefully placed over the damaged tooth, and your dentist will ensure the spacing and bite are accurate so your new crown functions and feels just like your own natural tooth.
