Update 2 weeks later — tried a replacement, hoped from a different batch. But this one was even less safe, no safety seals or even tape, and not even a product box, just a ready-to-ship baggie. Really sad, really needed this for a family member with low saliva, mouth psoriasis, and chewing-swallowing problems. No idea what to try next bc most products we have seen here have so many chemicals, sweeteners, and flavorings that are harsh for us, they would be impossible to use, worseners. We are giving up on this product, will try asking amazon for a final refund, will keep trying to find something else, and hope our family member will be able to keep eating in the meantime. Dumping unsafe product on consumers just hurts. Bought in mid-Apr-2026, expected to love this — simple, soothing ingredients for mouth psoriasis and low saliva. But, packaging was unsafe — safety tape on outside of cap, but no actual safety seal inside, cap was simple, loose screw-on not flip-top, and gel was leaking. Amazon ai said to not use, and to request a replacement or refund. So we chatted with Amazon customer service, and they refunded. We hope a replacement from a different batch will be safer.

Good product, but Amazon cheated me.

Size: 1 Count (Pack of 2)

I have dry mouth. The gel works well for me. I use it in my night guard and it keeps my mouth hydrated all night. However, Amazon messed up the order. I only received one tube instead of the 2 I paid for. Really annoying.
