Will Nightguard Bleaching Work
Well for You?
By Marc Lazare, DDS New York, NY
  • If your teeth are discolored by the natural process of aging, the prognosis for a beautiful, youthful smile is excellent. You can expect fantastic results in one to six weeks of treatment.

  • If your teeth are discolored as a result of smoking, coffee or other staining materials, you can expect great results anywhere from two weeks to three months. Naturally, smoking is not recommended while bleaching, as the results will take longer to recognize.

  • Teeth with stains that develop as a result of ingesting the antibiotic tetracycline usually have a favorable outcome within two to six months.

  • Single dark teeth will generally lighten over time, and a special nightguard for a single tooth can be made.

  • Brown stains due to excessive amounts of fluoride are usually removable in 80% of affected teeth, although some stains may recur.

  • White spots are not removed with bleaching, and may get lighter during treatment. If your teeth were dark to begin with, then bleaching may decrease the relative contrast of the white spots on your teeth.
Finally, it is important to note that teeth that are more yellow in color usually respond more favorably to tooth whitening than teeth that are grayer in appearance.
