What are the Zoom Whitening side effects?

Zoom! in office Whitening is completed on the teeth in an isolated field.  Your dentist, I am sure, placed cheek retractors, gum protector dam, cotton rolls and cotton pads all for the purposes of protecting your gums lips and tongue.However, everyone's salivary flow is different and for those that have a high volume of saliva it is possible that during the sessions some gel has seeped through the protector and onto your gums.  This shows as white tissue and can burn and be mild to moderately painful.  Vitamin E oil helps along with warm salt water rinsing 5-6 times during the first day.I have never, in my experience, seen a case where Zoom gel caused any long term issue with the gums.  I am sure it will return to normal within a day or so. However, If three days go by and the areas are still sore and white a visit back to your dentist is warranted!

Do not be alarmed.  Your gums that have turned white  from Zoom whitening will heal within 48 hours!  The cause of this was that a small portion of the bleach made its way under the protective barrier placed over your gums.  When this happened, it slightly irritates  the gums.  They will turn white first and then turn red before healing.  This is a common occurrence and things will be fine in a couple of days. 

Hi from Reno, Nevada!  I am so sorry that this has happened to you, but it is not permanent. You there will be miserable for awhile until all heals. The Dentist or his or her assistants should have placed retractors in the cheek area and also should have placed a gum protection dam and also used cotton rolls and pads so this would not happen.  If even if there is a little leakage you will have blisters, but I assure they will subside in time. Vitamin E might help and pain relievers. I am so sorry this happened to you!  The dental assistants should have stayed with you and checked on you......Your teeth will look great, but i would next time use another product like Opalesence . Take care and it will go away soon!

During the zoom procedure, care is taken to isolate the soft tissues of the mouth, including the gums around the teeth, from the whitening gel. However, if saliva happens to seep under the isolation/barrier, it is possible for some of the whitening gel to come in contact with the gums, and turn them white for a short period of time. These white spots on the gums are not permanent, and typically last only 24-48 hours. Using Vitamin E can also help to treat the gums if this happens. Hope this helps!

We have been using Zoom Teeth Whitening at our clinics in India for years now and am extremely happy with the results its been giving my patients. 
During the procedure we isolate your gums and other tissues exposing only the teeth to be whitened, however due to varying salivary flow in patients the material can sometimes seep through the barriers and contact the gums. This leads to the white, sore gums you mentioned.
This is not permanent and usually heals within 24 to 48 hours after the procedure. Applying some vitamin E gel helps in fastening the healing process.
