Frankly, the term "teeth whitening" is a misnomer. This is because the natural color of the teeth is not completely white. It is a combination of white and yellow as contrast. Generally speaking, this procedure is designed to restore the white color of your teeth.
Whitening can be done by a dentist in the dental office or at home using a variety of commercially available whitening products. However, it is important to consult your dentist before proceeding directly with home whitening. This is important because home remedies may not work or be suitable for everyone. Usually, the first whitening is done in the dental office and whitening products are used at home after the treatment. However, from a safety perspective, it should be monitored by a dentist both at home and in the office for best results.
