Is It Possible for Patient with Gum Disease to Get Invisalign?

If periodontal disease (or gum disease) is controlled, teeth can move as planned. If there is a lot of bone loss, there may not be a stable result and tooth loss is possible when attempting orthodontics in the presence of gum disease.
Waiting 6 months is likely overkill, but waiting 2-4 weeks and constant monitoring is likely enough.

It is not recommended that a patient with
ACTIVE gum disease get Invisalign or braces. This can cause increased bone loss
around the teeth. However, a previous history of gum disease that is now stable,
is not a contraindication for Invisalign.

Although Invisalign is a remarkable innovation in the orthodontic world, it has it's limitations. Some movements are inherently more difficult to achieve with plastic shells that snap over the teeth. For a person with periodontal disease however, Invisalign may be the treatment of choice. In addition to looking better and allowing patients to eat whatever they want, Invisalign offers patients the most flexibiltiy possible when it comes to keeping their teeth clean. That is essential for periodontal patients. Ask your orthodontist if your malocclusion is one that could be treated with aligners.

Invisalign needs only to be done on healthy gums. Make sure you listen to the dentist who is telling you to take good care of your gums even if the time frame is 6 months. Trying invisalign on unhealthy gums  or any orthodontic treatment, will not go well. Once you have your gums healthy and get the dentist's ok, then go for the invisalign procedure.  It is a wonderful way to keep your gums in good shape once your teeth are straight.  You will be able to brush and floss properly and have a beautiful healthy smile!  Good Luck!

If your perio pockets depths have shrunken to a managable level and there isn't any active perio disease -- many gum problems are improved by straight teeth so it makes sense to get perio treatment first and Invisalign second.
