At home tooth whitening kits enable you to achieve professional results at home. Some tooth whitening treatments can be used while you are asleep, for up to eight hours at a time. Other tooth whitening products need to be applied regularly for 30 minutes to one hour at a time.
You may have to use the tooth whitening gel trays for two to four weeks, or more, if your teeth are significantly stained.
Private Healthcare UK features professional tooth whitening providers and processes, including kits you can use in your own home.
