Teeth whitening can make your teeth sensitive, but there are effective ways to help prevent it. For each patient that is whitening their teeth, Dr. Darby recommends a sensitivity toothpaste such as Sensodyne or Colgate Sensitive, and they both work equally well. One week before whitening, you should start brushing your teeth with one of these toothpastes and you should continue throughout and beyond the whitening process. During whitening, Dr. Darby recommends placing a small amount of the toothpaste in your tray and wearing it for 30 minutes before and 30 minutes after each whitening session.
Sometimes the occasional pain or zinger will happen in spite of your best efforts, and for this pain Dr. Darby recommends whichever over the counter pain medication you usually take to relieves headaches or muscle pain.
If sensitivity continues, try taking a day off in between treatments or leaving your trays in for a shorter period of time.
Thankfully, many people who follow these steps do not experience much discomfort with the whitening process and are thrilled with the final results.
