Post-Appointment Instructions - Whitening (Bleaching)
It is not uncommon for your teeth to feel sensitive after whitening.
To avoid sensitivity, do not wear your teeth whitening trays overnight to avoid overexposure of the whitening gel on the gums.
Drinking particularly hot or cold beverages may trigger the sensitivity so it is best to avoid these if your teeth are already sensitive.
Using Sensodyne toothpaste or a high fluoride toothpaste may help alleviate some sensitivity; however any sensitivity should subside after a day or two.
Also, after removing your whitening trays, avoid staining food or liquids (coffee, tea, wine) for at least one half hour.
