Teeth whitening in Southfields – what is involved?
At Preventive Dental, we use professional bleaching as the most usual method of tooth whitening. Your dental team will be able to tell you if you are suitable for the treatment, and will supervise it if you are.
The “active ingredient” in the product is usually hydrogen peroxide or carbamide peroxide. As the active ingredient is broken down, oxygen gets into the enamel on the teeth and the tooth colour is made lighter.
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 stain 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?
Teeth whitening in Southfields from Preventive Dental can usually be done within three weeks. 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.
There is also laser whitening or “power whitening”. During this procedure a rubber dam is put over your teeth to protect the gums, and a bleaching product is painted onto your teeth. Then a light or laser is shone on the teeth to activate the chemical. The light speeds up the reaction of the whitening product and the colour change can be achieved more quickly. Laser whitening is said to make teeth up to five or six shades lighter. This procedure usually takes about one hour.
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.
What are the side effects?
Some people may find that their teeth become sensitive to cold during or after the treatment. Others may have discomfort in the gums, a sore throat or white patches on the gum line. These symptoms are usually temporary and should disappear within a few days of the treatment finishing.
If any of these side effects continue you should go to your dentist.
What about whitening toothpastes?
There are several whitening toothpastes on the market. Although they do not affect the natural colour of your teeth, they may be effective at removing staining. Therefore, they may improve the overall appearance of your teeth. Whitening toothpastes may also help the effect to last, once your teeth have been professionally whitened.
When might tooth whitening not work?
Tooth whitening can only lighten your existing tooth colour. Also it only works on natural teeth. It will not work on any types of ‘false’ teeth such as dentures, crowns and veneers.
If your dentures are stained or discoloured visit your dental team and ask for them to be cleaned.
How can I look after my teeth once they have been whitened?
You can help to keep your teeth white by cutting down on the amount of food and drinks you have that can stain teeth. Don’t forget, stopping smoking can also help prevent discolouration and staining.
