Our teeth become discoloured with age due to food stains and smoking. The colour of our teeth can be improved through “bleaching” or by using porcelain veneers or crowns.
To bleach teeth, the gums are protected by a plastic barrier and a whitening gel applied to the front surfaces of teeth. An intense light or laser is then used for about 45 minutes. The teeth may remain sensitive for a day and coloured foods and drinks avoided for 24 hours. Most patients bleach their teeth every two years.
If the teeth are badly stained, bleaching is inadequate and porcelain veneers or crowns may be required. Veneers, like crowns, are made from porcelain except that only the front and edge of teeth are trimmed. They provide a more cosmetic result than bleaching.
In very severe cases, even veneers are insufficient to mask the stains as they are thinner and may not be able to hide the underlying stains. In these patients and for patients with strong bite forces, veneers are not suitable and porcelain crowns are required.
