Surface stains and internal discoloration can be caused by:

  • The natural aging process
  • Using tobacco (smoked or chewed), drinking coffee, tea,
    colas or red wine, and eating pigmented foods such as
    cherries and blueberries
  • Accumulation of plaque and tartar deposits
  • Ingesting too much fluoride (more than 2 parts fluoride per million
    parts water) when teeth are forming, which gives teeth a "mottled" look
  • Treatment with the antibiotic tetracycline during childhood
  • Trauma to the teeth that may cause a brown, gray or black color

There are many reasons for whitening your teeth, including:

  • The boost to your confidence and self-esteem that comes from a great smile
  • A younger appearance
  • A special event such as a wedding, job interview or class reunion
  • To make a positive first impression on others
  • To simply reverse years of everyday staining and yellowing

Before beginning any whitening procedure, be sure to consult with your dentist. Only he or she can evaluate whether you're a suitable candidate for a particular treatment.
