What are some possible side effects of teeth bleaching?

Question

Shalini Mirchhandan · Answer

Some unpleasant side effects include chemical burns from gel bleaching (if a high-concentration oxidizing agent contacts unprotected tissues); over-bleaching known as the ‘bleached effect’, particularly with intensive treatments (products that provide a large change in tooth color over a very short treatment period like one hour); pain if you have ‘sensitive teeth’ caused by open dentinal tubules; a risk of increased hot/cold sensitivity; and a risk of bleachorexia (an unhealthy obsession with whitening one’s teeth).
