Was just diagnosed with Bell's palsy and getting married. How can I get mouth to turn up for wedding? Would facelift tape work?

Unfortunately there is no quick fix for Bell’s palsy. After taking the initial course of antiviral and steroid medication, your body needs time to heal on its own. I recommend scheduling an appointment with a facial nerve specialist to discuss your options. Depending on how long ago you were diagnosed, and when your wedding is planned for, it’s possible that you could be a candidate to begin facial physical therapy and perhaps even receive Botox injections to help address some of your concerns. I caution you to be weary of going to just any physician for these treatments. It’s crucial to find a doctor who specializes in treating patients like yourself who have Bell’s palsy. I help people with all different types of facial paralysis on a regular basis and would be happy to see you for a consultation. Once I am able to assess you, we can discuss treatment options and create a customized plan to get you looking your best for your wedding.

Bills palsycongratulations on your upcoming wedding. Unfortunately, cosmetic surgery has no place in the management of Bell's palsy. Careful monitoring by your primary care physician or neurologist  Plus medical management steroids is the mainstay of treatment. After that it's just time to allow  hopefully complete resolution of your signs and symptoms. 

I am very sorry to hear this. There is nothing to do at this point except let it all try to resolve.  The down-turned mouth can only improved possible with filler which can be reversed if it doesn't look good. After a year or so, the can be improved with facial animation procedures.  Good luck.
