So what is tooth whitening?
Tooth whitening can be a very effective way of lightening the natural colour of your teeth without removing any of the tooth surface. It cannot make a complete colour change, but it may lighten the existing shade.
Why would I need my teeth whitened?
There are a number of reasons why you might get your teeth whitened. Everyone is different; and just as our hair and skin colour vary, so do our teeth. Very few people have brilliant white teeth, and our teeth can also become more discoloured as we get older.Your teeth can also be stained on the surface by food and drinks such as tea, coffee, red wine and blackcurrant. Smoking can also stained teeth.‘Calculus’ or tartar can also affect the colour of your teeth. Some people may have staining under the surface, which can be caused by certain antibiotics or by tiny cracks in the teeth which take up stains.
How long does this take?
The total treatment can usually be done within three to four weeks. First, you will need two or three visits to the dentist. Your dental team will need to make a mouthguard and will take impressions for this at the first appointment. Once your dental team has started the treatment, you will need to continue the treatment at home. This means regularly applying the whitening product over two to four weeks, for 30 minutes to one hour at a time.However, there are now some new products which can be applied for up to eight hours at a time. This means you can get a satisfactory result in as little as one week.
The total treatment can usually be done within one/two hours by the dentist.
How long will my teeth stay whiter?
The effects of whitening are thought to last up to three years. However, this will vary from person to person. The effect is less likely to last as long if you smoke, or eat or drink products that can stain your teeth. Ask your dental team for their opinion before you start the treatment.
Can a single tooth which has been root filled be whitened?
Yes. Sometimes dead teeth go discoloured after a root filling. If the tooth has been root treated, the canal (which contained the nerve) may be reopened. The whitening product is applied from the inside to whiten the tooth.
