How Do Whitening Kits Work?
Most whitening kits contain a chemical, such as hydrogen peroxide which can act on the stains on the surfaces of the teeth and therefore remove them. Hydrogen peroxide is often used in teeth whitening procedures carried out by cosmetic dentists. Whitening kits usually contain strips or trays to keep the whitening agent in contact with the teeth so that it can gradually work on the surface stains. Many whitening kits contain several sets of strips or trays which can be used each day to gradually whiten the teeth.
How to Choose a Whitening Kit
When choosing a tooth whitening kit, you’ll need to decide what form of whitening product you want to use. Many people find whitening strips convenient as they adhere to the surface of the teeth while the treatment is taking place. Others prefer to use a gel which can be applied using a swab or in a mouth tray.
You also need to consider the speed of whitening that you require. Some kits offer accelerated whitening. However, people with sensitive teeth might prefer to use a gentler formula designed to deliver results gradually over several days or weeks.
How to Use Whitening Kits
Generally speaking, whitening kits are very easy to use. However, it's very important to follow the instructions carefully. Leaving whitening strips or gel on the teeth for too long could cause sensitivity, whereas removing them too soon could mean that they can't deliver their full whitening potential.
If you are using a gradual whitening formula, patience is necessary. It could take a couple of weeks to remove the stains from your teeth and restore them to their natural whiteness. Once you have whitened your teeth, you can help to maintain the results by cutting back on common causes of staining such as red wine, black tea and coffee. back to top »
