The good news is that even if you have veneers or crowns, you can still whiten your teeth. These dental restorations will not be harmed by whitening gels or strips. This is one reason why your dentist may advise you to whiten your teeth before getting a dental crown or veneers. However, you should know that any treatment that contains ultraviolet light or lasers could potentially destroy your dental work. Therefore, any option that uses an LED lamp or laser should not be used on people who are wearing braces, temporary plates, or other dental appliances. Also, any option that uses these lamps or lasers should only be done by providers who know how to avoid damaging your oral health. So, yes, you can use whitening strips on your teeth with no problem caused by your dental work. However, you should only use this method together with another home tooth-whitening regimen to get the best results from it.
