Toddler approved
My child actually enjoys brushing their teeth now because they love the grape flavor of this toothpaste. The taste is mild and kid friendly without being overly sugary or strong. It leaves their teeth feeling clean and their breath fresh after every use. I also like that the gel texture is smooth and easy for kids to use on their toothbrush. The packaging is simple and convenient for everyday use at home or while traveling. It has become part of our nightly routine without any struggles or complaints. Overall, this is a great toothpaste option for kids and I will definitely buy it again.

Great product!
I always do extensive research when it comes to buying a health and beauty product. When I saw the review on this toothpaste I researched the website and reviews on and off of Amazon. I came across this product because my toddler has developed white spots on her teeth and I was not too excited about that. I originally bought the mint and used it on my toddler and myself. I love the mint. A little goes a long ways. It is a gel form but lathers well in the mouth. I have noticed when using this toothpaste that the amount of gunk I scrape off of my tongue after brushing is about 95% less than with normal toothpaste. That tells me that something is working in this toothpaste. Since using this toothpaste I have also received comments on my teeth. I have some sensitive spots when I floss and they are no longer sensitive after using this toothpaste. I ended up buying my daughter the grape flavor as it is more her flavor. She doesn’t mind the toothpaste. Her teeth are looking better, the white spots have started to minimize. I have no tried the grape flavor but another adult in my household has and they too like it and has said it lathers very well. I ended up buying the mint mouthwash as well. I was a bit hesitant at first because reviewers were saying it burned their mouth when using it and they refused to use it anymore. I happen to love the mouthwash. It does almost always burn my tongue but that is because of the damage I do to it myself from eating sour and salty foods. The mouthwash gives me an intense clean feeling. I use it every morning and night before bed. I also love the fact that these products do not contain acid (for shelf life) like most other brands do. Acid breaks down your enamel and that’s something you definitely want to avoid. I give his company a high five for that in itself! I’d recommend this toothpaste and the mouthwash to anyone looking for a great toothpaste that does as it says and contains no harmful ingredients. This company truly wants to protect your teeth and gums. I will co tongue to buy this for myself and my family.

The best toothpaste
Carifree is the best for remineralizing the tooth surface- it has a high pH (alkaline), very low abrasiveness, xylitol and nano-hydroxyapatite, so it will not damage your teeth or microbiome. Had extremely sensitive teeth in the past, started using this one 5 years ago and couldn’t be more pleased. Sensitivity was gone in a short amount of time and it feels very pleasant and smooth on teeth.

Hedging my bets
This stuff is expensive, so don't use it like you'd use crest sparklefun or whatever. You don't need to use a lot. I don't like that all the other hydroxyapatite toothpastes are filled with hippie bullcrap about being fluoride-free. The effectiveness of hydroxyapatite pastes hasn't been proven long-term yet, and basic fluoride toothpaste didn't seem to be doing it for me on its own (also a lot of them had harsher detergents that left me with canker sores.) So, this product is perfect for hedging my bets with old and new dental technology. As for results, I think it's done well for me. I don't have hot or cold sensitivity and haven't had a toothache in a long time. Remember well: nothing will work if you don't brush morning and night. Nothing. Well, 'cept dentures, but you still have to clean those if you don't want a stink mouth.
