Help! Used Zoom teeth whitening and gums are severely damaged. What should I do? (photo)

Hi:Sorry to hear about the gum damage.  It's best to use liquid vitamin E and it should heal with in a few days.Best,Dr. Maddahi

Although your Invisalign® retainers may have seemed like a good idea at the time, they are not appropriate for tooth whitening gel as the custom-made Invisalign® clear aligners are made to fit snugly causing the gel to ooze into your gums. Even if you only used a small amount of whitening gel, it will still leak out of the retainers. This is why you are experiencing pain, redness, and discomfort. Thankfully, the sensitivity will go away. Try putting some Vitamin E on your gums, which may help ease some of the discomfort.
In future, ask your dentist about custom made tooth-whitening trays that you can take home or about in office tooth whitening with Zoom!®. 

Great photo!By the time you read this your gums will likely feel a lot better. This pain usually goes away in a day. The damage is not permanent.Vitamin E gel rubbed on the area will soothe the pain and promote healing.Once you finish Invisalign, have bleaching trays professionally made. They will keep you out of pain!

It does appear you over applied the whitening gel. i suggest putting some vitamin E oil on it. Will be soothing and will make it heal faster. Invisalign retainers are not the best option to use as whitening trays. They fit too closely to the teeth and so all of the gel oozes out. You need a more flexible tray to be more ideal for whitening. 

Hello,
The bleaching of the gums is usually temporary and will return to normal pigmentation in a day or two following Zoom teeth whitening procedure. If you have sensitivity you can ask  your dentist for fluoride gel prescription to inject inside your trays to help with sensitivity.
Hope this helps,
