In my case, I was allowed to take my bandage off on day 3 and could take my sling off to shower. Your surgeon will tell you what your rules are, I'm not here for that. During these first few days for me, I lived in my Reboundwear Jacket and used disinfecting wipes, like the kind you go camping with. https://www.reboundwear.com/discount/RH10
Deodorant. I started on a cream deodorant 2 weeks before surgery that was supposed to last up to 7 days. My idea was not to stink AND not to have to put deodorant on. In theory this should have worked. The deodorant didn't do the trick for me though. Applying it was fine, but it didn't real work on the stink. Who knows, it may work for you!
Mouthguard. I wear a mouthguard at night and typically clean it with a toothbrush in the morning. That wasn't going to possible, so I purchased a bunch of retainer cleaner tablets. They are wrapped individually, so I opened every one of them and put them in a tupperware container (like my medications) so I could easily get to them one handed.
Showering. Once you are able to hop in the shower (where you should have a no-skid mat) you will feel much better but it's still going to be tough. I had to wash the morning of surgery with anti-bacterial body wash. I found the Dettol below on Amazon. Since I still had incisions, I continued to use it and felt much safer in the shower. To wash my hair, I would squirt the shampoo and/o conditioner on my knee and scoop it up with my good hand to massage it in. I also used a wide tooth comb to "brush" the shampoo and conditioner into my hair which did a much better job.
More to come on this as well. I just met with Dr. Nagda today and he asked that I find some shower brushed and booty wipers to share with you.
Brushing your teeth. Everything was exceptionally harder for me since I am right handed and had surgery on my right shoulder. If you are in the same situation, the only thing I can tell you is to start practising with your opposite hand as soon as you can. Also - Dental Picks! I love the scope ones the best.
