Who doesn’t want beautiful white teeth and a radiant smile? Home bleaching is a relatively easy way to make your teeth whiter. Firstly, custom fitted trays will be made by the dentist. In the custom fitted mouth trays, you apply the bleaching gel and wear it in your mouth for several hours a day. The trays can be used again and you can buy more bleach gel if needed. First ask your dentist or dental hygienist before bleaching. Not in all cases is bleaching inappropriate.
