Are whitening products more effective on teeth with stains of certain colors?

Asked more than five years ago by Janice

My teeth are kind of gray - can I whiten them?



Teeth whitening works best on surface stains, but can help to remove staining inside the tooth that comes from natural aging. Ideal bleaching candidates are those whose teeth have discolored or stained due to the consumption of tea, coffee, wine or cola. Dentists can also help people with stains or discoloration caused by either genes or antibiotic use, but results may not be as dramatic. Dentists say that they can frequently lighten such stains, but not as much as many patients would like. Read our article about tooth coloration and bleaching at
