"I absolutely loved this product! The Pearl Serum left my mouth feeling incredibly clean and fresh, and it was easy to use with the rinse cup. It has a refreshing taste without being overpowering, and I noticed my mouth felt cleaner for much longer after using it. The packaging is also high quality and convenient. I’ve really enjoyed adding this to my daily routine and would definitely recommend it to anyone looking for a refreshing oral cleanser!"
"I like this more than I thought I would. The perfect minty after rinse. The only complaint is that the cup is too big and the lines aren’t helpful for measurement. But it’s solid and once you figure out the right amount for you, it works great."
"Enjoying the Pearl Serum mouthwash. No chemicals harshness or burn. Just 1-2 drops in water and swish. It leaves the mouth clean and fresh."
"This serum is super refreshing and I love that it has no harsh chemicals! The dropper method is nice because it makes it easy to travel with, and I can make it stronger or weaker depending on my preference. I think the future of mouthwash is undoubtedly like the pearl serum!"
"I have never had my teeth feel so clean! I truly think Nathan and sons pearl serum added makes me have a fresh breath and a slightly minty taste all day. Highly recommend!!"
"This product is fantastic especially paired with the toothpaste! My teeth have never felt or seemed healthier, and this product seems to prevent bad breath from taking hold even if I dont brush!"
"Oh my! This serum is better than any mouthwash I've ever used. So very fresh. The rinse cup is perfect in size. It takes up no room and is easy to keep clean. I'm glad I decided to try it."
"I’ve really enjoyed using the toothpaste powder and pearl serum. My mouth feels soo much cleaner and fresh! I also feel like I run out of my regular toothpaste so fast but the powder seems to last forever."
"These are awesome. A small suggestion, to add botanical menthol and peppermint oil to the mint flavor because I want that fresh feeling of regular mint gum. Will be a long time customer."
"Thank you for making this fluoride-free! I have been searching for fluoride-free options given that I have thyroid issues. This serum is strong, but it does the trick. My mouth feels so refreshed after use. Thank you!!!"
