TwTooth whitening is a popular industry these days, racking up billions of dollars. People want white teeth. White teeth look nice and make you feel better about yourself. They even come with many other perks. Research shows that people with a nice smile have more romantic opportunities, more professional opportunities, more friends, and overall get more attention, but are you a bleachaholic? Tooth whitening can be a good thing, but over bleaching can damage your teeth. How often do you bleach? Take our true or false quiz below to find out the results of over bleaching.

True Or False?

  1. True or False: Just like anorexia, there is such a thing as bleachorexia.
  2. True or False: Too much bleaching can have the opposite effect on your teeth.
  3. True or False: Extrinsic stains respond well to bleaching. but intrinsic stains do not.
  4. True or False: Intrinsic stains respond well to bleaching.
  5. True or False: Translucent dentition is not the only harm of over bleaching.


  1. True: The term bleachorexia was coined to describe people obsessed with whitening their teeth. They are addicted to bleaching. No matter how white their teeth become they are not satisfied.
  2. True: Over bleaching your teeth can do damage and may actually do the complete opposite of whitening. Excessive bleaching can make your teeth translucent, meaning the inner dentin (the layer under the enamel) shows through giving your teeth a yellowish tint. Once your teeth become translucent they will never look white.
  3. True: Extrinsic stains respond well to bleaching because they are on the outside of the enamel. Extrinsic stains include stains from: dark soda, red wine, coffee, tea, tobacco.
  4. False: Intrinsic tooth stains do not respond to bleaching. Intrinsic stains are caused by dark pigmented molecules adhering to the crystal structure of the tooth during its formation. Such stains include: tetracycline stains, fluoride stains, hyperemia.
  5. True: Other harmful results of over bleaching can include hypersensitivity to heat and cold, irritation of your tongue, cheeks, gums, or other oral tissue, nausea, and the removal of tooth enamel leaving your teeth vulnerable to decay.
