Background

CD9 is a 24-kDa tetraspanin membrane glycoprotein with four transmembrane domains and two extracellular loops that is widely expressed on hematopoietic and non-hematopoietic cells, where it organizes tetraspanin-enriched microdomains that integrate adhesion, signaling and trafficking by associating with integrins, EWI-2/F, and other tetraspanins to regulate cell adhesion, migration, fusion, exosome biogenesis/secretion, immune activation and tumor suppression, and its large extracellular loop is essential for sperm–egg fusion, while its presence in exosomes marks these vesicles for intercellular communication and its altered expression influences cancer progression, viral entry and stem-cell pluripotency.

Great SLS free toothpaste
Flavor Name: Peppermint, Size: 5.25 Ounce (Pack of 1)
This toothpaste has saved me! Anytime I use regular toothpaste it makes me throw up and ever since I have started using this toothpaste. I have not thrown up one time. This is a great too toothpaste if you need a toothpaste, that is SLS free. It has a very clean taste and makes my teeth very clean.

It’s not your average toothpaste consistency
Flavor Name: Peppermint, Size: 5.25 Ounce (Pack of 1), Flavor Name: Peppermint, Size: 5.25 Ounce (Pack of 1)
My teeth have become a little sensitive recently so I started using Sensodyne. Through some research, I discovered hydroxyapatite. I was extremely excited and intrigued at the idea of its ability to strengthen tooth enamel so I just had to give it a try. I first started with Risewell, but then my dentist recommended David’s due to it having nano-hydroxyapatite. I really like this toothpaste. As you can see, it’s almost all finished. I like the flavor, I like that’s it’s fluoride free so you can swallow it, and it’s made in the USA. I’m obsessed with the packaging too! It’s got a very minimalist and modern aesthetic and it comes in a recyclable metal tube. I also love that it comes with with a little metal key to help push put all the toothpaste. I definitely felt like this toothpaste improved my teeth sensitivity as well as helped whiten my teeth. I love that it’s so convenient to order on Amazon so it ships quickly (as opposed to Risewell). If you’re not familiar with hydroxyapatite toothpastes then you may be surprised by the texture. It’s very loose and watery. It doesn’t really lather up the way toothpaste does. I feel like that’s one nuisance with using these natural toothpastes, but I would also say that the benefits of using it outweigh that. Overall, this is a solid product and I will definitely continue to use it as well as recommend it to others.

Good product.
Flavor Name: Peppermint, Size: 5.25 Ounce (Pack of 1)
This is a little different texture from regular toothpaste and it doesn't lather in your mouth. However, it seems to clean really well, and taste is fine.

Gentle, Effective Toothpaste That Leaves My Mouth Feeling Clean
Flavor Name: Peppermint, Size: 5.25 Ounce (Pack of 1)
I bought Davids Fluoride-Free Xylitol Toothpaste because I wanted a natural alternative that still supported whitening and enamel health, and it has become my go-to daily toothpaste. I use it morning and night, and the peppermint flavor is refreshing without being overpowering, leaving my mouth feeling clean and energized. I noticed my teeth look brighter after a couple of weeks, and my gums feel healthier and less sensitive compared to when I used regular fluoride toothpaste. I love that it’s free of sulfates and harsh chemicals, and the texture is smooth and easy to apply to my toothbrush. The sleek, eco-friendly packaging is a bonus, and it feels good to use a product that aligns with both my oral care needs and my values.
