DISADVANTAGES OF TOOTH WHITENING

Not all smiles respond equally well to bleaching treatments, making tooth-whitening procedures unsuccessful in some cases. 
As the American Dental Association explains, yellow-hued teeth typically bleach well, but whitening products may not improve the appearance of teeth tinged with brown or gray tones. 
In addition, whitening chemicals cannot change the color of crowns, bonding materials or tooth-colored fillings; if these materials appear on visible sections of your smile, tooth-whitening procedures may cause them to stand out against your natural teeth, creating a displeasing appearance.

According to the Goa Dental Clinic, tooth stains resulting from certain drugs—such tetracyclines—may also be unresponsive to bleaching treatments.
tAlthough tooth-whitening treatments are generally safe, the procedure can result in several uncomfortable side effects. As the Consumer Guide to Dentistry explains, bleaching may increase the sensitivity of your teeth for several days after treatment, leading to pain while eating or drinking. 
You may be at particular risk for sensitivity if you have gum recession, faulty dental restorations or cracked teeth. In some cases, people also feel sharp, spontaneous pains in their front teeth shortly after a tooth-whitening session, and many people using peroxide-based whiteners experience gum irritation.
