I follow a dietician for those who deal with Acid reflux and LPR. Being without flavor especially peppermint, as mentioned by the dietician, can be helpful for some. I have found this to be true with this product. It seems to have helped reduce, or at least not add to, my feeling of throat and mouth burning.

Good Quality (when purchased)

Style: Unflavored (Pack of 1)

Genuinely the dream toothpaste I've been looking for since I don't like mint, its slightly sweet and the texture has a tiny bit of grit but overall its pretty good I'd say. But please be warned and look at the One star reviews, a lot of them are recent and are mentioning a change in the ingredients one of which said experienced a severe alergic reaction. A decrease in amount of toothpaste per tube, and lesser quality. I bought in bulk months and months prior but the one star reviews I've seen are all recent and oldest usually being from February. Heres hopes they change things back.

Doesn't improve breath but good for peeling

Style: Unflavored (Pack of 1)

I got this for two reasons: 1) regular toothpastes make my mucous membranes peel like crazy, 2) intense mint seems to heighten my post-nasal drip. This does not cause any peeling, which is great! The formula does foam up slightly, so it does feel like it is cleaning, if only gently. I'm not noticing a big difference with my post-nasal drip, which is okay, it was probably a long shot. The cons: The texture is quite runny and it seems like I have to use a lot to get the foam I'm used to. I know most people are using this because it doesn't have an intense flavor, but it does nothing to neutralize bad breath. I eat a lot of garlic and drink coffee, so it feels like I'm not freshening my breath much. It's also a bit pricey. I could see this being very valuable to someone with a true mint allergy, though.

The Best Fluoride-Free Toothpaste I've Tried

Flavor Name: 1. Sensitive Mint, Size: 5.25 Ounce (Pack of 1)

I've been using Davids Hydroxi Fluoride-Free Nano Hydroxyapatite Toothpaste for several weeks, and it has completely exceeded my expectations. The first thing I noticed was how clean and smooth my teeth felt after brushing. Unlike many natural toothpastes, it leaves a genuinely fresh feeling without being overly harsh. The natural peppermint flavor is refreshing and pleasant without the intense burn that some mint toothpastes have. What really impressed me is the nano-hydroxyapatite formula, which is designed to support enamel remineralization and reduce sensitivity. My teeth have become noticeably less sensitive to cold drinks, and they feel stronger overall. Nano-hydroxyapatite is gaining attention as a fluoride alternative because it can help replenish minerals in enamel and reduce sensitivity. I also appreciate that it's: Fluoride-free SLS-free Made in the USA Vegan Uses high-quality ingredients Comes in a recyclable metal tube The whitening is subtle but effective. My teeth look brighter without any increased sensitivity, and the toothpaste is gentle enough for daily use. The inclusion of xylitol and hydroxyapatite makes it feel like a premium oral care product rather than just another natural toothpaste. While it's more expensive than conventional toothpaste, the quality and ingredients justify the price. Even dental professionals reviewing hydroxyapatite toothpastes have noted benefits for remineralization, sensitivity relief, and plaque reduction. Overall: 5/5 stars. If you're looking for a fluoride-free toothpaste that supports enamel health, helps with sensitivity, and leaves your mouth feeling exceptionally clean, Davids Hydroxi is absolutely worth trying. Highly recommended!
