Didn't like the taste
Size: 1 count (Pack of 1)
Bought this to use for my mom, who sleeps with her mouth open. She did not like the taste, at all.

Exceptional dry mouth gel
Size: 1 count (Pack of 1)
This stuff for dry mouth is amazing. I love the taste and the coating it leaves is great until I eat and then reapply. Best product I have used although more expensive than I would like.

2 tries — No actual safety seal, leaking
Size: 1 count (Pack of 1)
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.

Great product!
Size: 1 count (Pack of 1)
I have a history of radiation to the head and neck due to cancer. I usually use xylimelts for nighttime which are my go-to. And I can't really sleep without them. But because I use the xylimelts every night, I sometimes get sore gums. I bought this as an alternative. It works well but not as great as xylimelts. It keeps the cheeks and gums hydrated but not the tongue. I still woke up and had to have water because my tongue was dried out. It's the best backup to xylimelts I have found for overnight relief so far. Definitely going to buy again. Likely for daytime use and as a backup to xylimelts.
