Downsview Dental Care In-House Versus Take-Home Teeth Whitening | Page 10

In addition, the dentist gives you a clear procedure on how to care for your
teeth before and after wearing the bleach trays. You are not supposed to eat,
drink, or smoke before wearing the bleach trays. Avoid any strong colored
foods 48 hours prior to bleaching to ensure the best results. Once the bleach
trays are on, you have to stay for 30 to 60 minutes without consuming any
food.
If some of the bleaching gel falls on the gums, some sensitivity may be felt.
Fortunately, your doctor will prescribe a peroxide solution that will help
soothe the gums. Moreover, modern day bleaching gels have a high
viscosity which helps wipe off the excess before it spills over to the gums.
Your dentist will also give instructions on when to wear the bleaching trays.
There are bleaching trays that can be worn overnight with the addition of
peroxide gel to protect the gums from inflammation.
