The fastest way to whiten teeth without going to the dentist?

No: There are crest whitening available at the pharmacies but because of their low concentration usually wont give the optimal result. The easy and effective way is having dentist fabricate a home whitening tray that you can use at home during the day or night.

Home whitening kits: Some of the home whitening kits have the same ingredients that dentists use, just a lower concentration. Follow the recommendations on the package. Trying to use them for a longer time each day may speed up the bleaching process, but could increase the risk of discomfort from the bleaching process.

Whitening : One can try store-bought whitening kits. I encourage you to see a dentist prior to bleaching to make sure your teeth are sound so that complications from whitening can be avoided.

No good way: Dental whitening strips and whitening toothpastes may help a little, but best if teeth cleaned by your Dentist first. Custom trays made by your Dentist used with whitening gel much more effective. Best bang for your buck, ask your Dentist for help.

Store Whiteners: Some of the well know manufactures have some worthwhile products that can do this. However a good dental cleaning is very useful first. You cannot whiten such things like: cavities, decalcification, etched tooth structure from acidic foods and/or bacteria, stains within the porosity of the tooth structure, fillings, crowns, and many more things that a dentist can help you identify and assist.

Wear Dark Clothes: There are no quick and easy solutions.
