Review on 🦷 Get Perfectly Molded Mouth Trays with DIY Thermo-molding Technique - Instant White Smile Wholesale by Julie Bauer

Not sure what I'm doing wrong, I've used these guys before with no problems. I turned off the water for a few seconds, sucked the air out, pulled it out, and my gums started bleeding profusely, leaving bruises. I have no idea what happened. Also hardly made an indentation for the front teeth. I tried again for the bottom teeth. No weird bleeding or bruising but only the back 4 teeth are slightly dented. I used them on a new whitening paste so I'm guessing it "worked" but is still confusing. Based on other reviews they work, so for the price and quantity if you can get them to work that's great. The circled part is where it happened to bleed and immediately bruised. Aside from being a little crooked, I have healthy gums and teeth, so it's just weird.
