Tooth whitening can be a very effective way of lightening the natural colour of your teeth without removing any of the tooth surface or damaging it.
You will have trays made specially to fit into your mouth. The whitening gel is then put in the trays and you will be given a routine to follow at home.
The active ingredient in the whitening product is usually hydrogen peroxide or carbamide peroxide. As the active ingredient is broken down, oxygen gets into the enamel and dentine on the teeth and the tooth is made lighter.
The total length of the treatment can vary depending on how discoloured your teeth are and the shade you want to get to. It can usually be finished within two to four weeks.
First, you will need up to four visits to the dentist. We will need to take a scan for your custom made whitening trays at the first appointment. Once our laboratory has made the whitening trays we will demonstrate how to place the bleach gel in the tray. You will be given whitening gel to take away and continue the treatment at home.
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.
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.
Tooth whitening can only lighten your existing tooth colour, and will only work on natural teeth. It will not work on any types of false teeth, such as dentures, crowns and veneers.
