Fluoride + hydroxyapatite toothpaste: what they do and why both matter.
The questions people search most before switching.
1000ppm vs 1450ppm
What's the difference between 1000ppm and 1450ppm fluoride?
1450ppm is the dose recommended from age 6 upwards. 1000ppm is the lower dose used in toothpaste for ages 3–6. GudYu's Remineralising & Whitening Tabs contain exactly 1450ppm in every tablet.
Fluoride + hydroxyapatite
Can fluoride and hydroxyapatite be used together?
Yes — and they work better together. Fluoride hardens the outer enamel surface; hydroxyapatite, the mineral teeth are made from, helps rebuild enamel that's already worn. GudYu tabs combine both in every dose.
Whitening
Do toothpaste tablets actually whiten teeth?
Yes. Calcium carbonate and hydrated silica gently polish away surface stains from coffee, tea and wine — no harsh bleaching agents, just consistent, visible brightening over time.
Simple as Chew. Brush. Spit.
Three simple steps to cleaner teeth, healthier habits, and plastic-free brushing every day.
01
Chew
Pop one tab in and chew for 3 seconds. It turns into a foamy paste, all on its own.
02
Brush
Brush for 2 minutes as usual. No extra water needed — just the tab and a toothbrush.
03
Spit
Spit it out. No rinsing needed, leaving the fluoride on keeps it working longer for protection.
The toothpaste tablet built to actually replace your tube.
Most "eco" toothpaste swaps ask you to give something up — less fluoride, less foam, less whitening. GudYu doesn't. Every tab carries the full 1450ppm fluoride dose dentists recommend from age 6, paired with hydroxyapatite to help rebuild enamel from the inside out. The only thing missing is the plastic tube.
1450ppm fluoride — the full dose, not a diluted "natural" version
Hydroxyapatite remineralises enamel and helps reduce sensitivity
Calcium carbonate and hydrated silica lift surface stains for a visibly whiter smile
Fresh mint, zero mess — no spills, no half-empty tubes in the bin.
One tab = the exact right amount, every time

Very easy to use and feels like just the right amount of "toothpaste" everytime.

Thanks for you great feedback KP, so happy you're loving the new formula!
These tablets are excellent at their most important function: cleaning teeth. Additionally: they taste great, are easy to take with you when travelling, result in less bathroom mess and clutter, and because there is zero plastic, they are good for the planet too.
Store owner replied:
Amazing to hear, we love that you're loving your tabs!
My only niggle would be tins being supplied at every refill, but I understand this is changing soon. They are very convenient, help my sensitivity and taste good. I much prefer a tab to messy old tubes of goo.
As a Dental Hygienist looking for more environmentally friendly dental products to recommend to my patients I have been trying various toothpaste tablets. This is the 6th brand trialed & I think I have found my favourite.
I liked the combination of fluoride & hydroxyapatite. They dissolve nicely & aren’t ‘chalky’ as some I have previously tried have been. They have a pleasant mint flavour. The pot looks good & is a decent sized number of tablets
I was hoping for UK made/dispatch so this is also a huge plus.
I have a few areas of sensitivity from brushing too firmly in the past & whereas previous tablets did not ease this, this formula has greatly reduced the sensitivity.
I suffer from burning mouth syndrome & this has also reduced.
Just one question.. why not sell refills in paper packages? I know the metal pots are easy to recycle but I just wondered if this is going to be an option in the future but that is my only query?
I will definitely be recommending 💫

Hi Susan, thank you for your fantastic review of our tabs, we're thrilled you're enjoying them. Regarding the biodegradable pouches, these are on route and will be launched as soon as we have them in hand. Team GudYu
I love this product not just because it's plastic free and environmentally friendly, but there's less mess and waste when using it and it, also does a great job of looking after my teeth, would definitely recommend anyone to give them a try and they will be a convert just like myself. 😁
Great toothpaste tablets- really enjoying using them. Super happy with the product- nice minty taste - teeth feel fresh and clean after using. Think they seem whiter too.
Love that this product has fluoride and hydroxyapatite and is sodium lauryl sulphate free too which typically irritates my mouth. Happy customer :)
Firstly, the fully recyclable packaging is impressive and aligns with the brand's ethos. The tablets boast excellent quality and are user-friendly. I appreciate their strong menthol flavour, which leaves my breath fresh for a prolonged period. My teeth feel clean after use. They are convenient for travel since I can easily pack them in my carry-on bag. I will definitely be ordering more.
This is undeniably the best! Love the way my teeth feels after use and the mint flavour. My daughter loves it too, great product. I love the fact it is vegan and the packaging is pretty and eco friendly unlike plastic tooth paste tubes.

What we left out — on purpose.
A good ingredient list is short. A better one is honest about what isn't there. These are the eight things you won't find in a GudYu tin — and the reasons why.
SLS
The harsh foaming agent in most supermarket toothpastes. We use gentle coconut-derived SCS instead.
Parabens
Artificial preservatives linked to hormone disruption. Not welcome here.
Gluten
Suitable for people with coeliac disease or gluten sensitivity.
Palm Oil
No contribution to deforestation. Ever.
Artificial Flavours
The power-punching minty taste is natural aroma only — nothing synthetic.
Animal Testing
100% vegan and cruelty-free. Always has been, always will be.
Too Much Fluoride
Exactly 1450ppm — the right amount for ages 6+. No more, no less.
Plastic Tubes
Every tube ever made is still on this planet. Ours aren't.
As clean outside as inside
Every toothpaste tube you've ever thrown away is still on this planet. GudYu tabs come in a reusable aluminium tin you can refill — forever. One small swap. A lifetime of difference.
Reusable & Recyclable Tin
100% aluminium. Keep it, refill it, recycle it forever.
Compostable Refill Pouch. Coming Soon
Kraft paper + PLA. Plant-based, plastic-free & compostable.
Zero Plastic Tubes
The average person throws away 300 toothpaste tubes in a lifetime. With GudYu, that number is zero.
