Michael R.
"My teeth finally feel comfortable again – cold drinks don't scare me anymore and they look noticeably smoother."

People keep asking what I changed
"After a month of daily use, my dentist noticed my enamel looked stronger. The serum format is genius – feels like proper skincare but for your teeth."

Finally, sensitivity relief that works
"Hands down the best dental treatment for sensitivity I've ever tried. My teeth feel comfortable for the first time in years – even with cold drinks."
The easiest upgrade to my routine
"I love that I just drop it onto my toothpaste and brush like normal. No messy trays or LED lights. My teeth look smoother and noticeably brighter."

Frequently Asked Questions
What exactly is Tooth Armour Toothpaste Serum?
+
Tooth Armour is a highly concentrated oral care serum powered by nano-hydroxyapatite and 5 additional active ingredients. You add a few drops to your toothbrush – either on top of your regular toothpaste or on its own – to support enamel strength, sensitivity relief, and whitening in a single daily step.
Is it fluoride-free?
+
Yes. Tooth Armour is completely fluoride-free. It uses nano-hydroxyapatite – a mineral that mirrors the structure of natural enamel – to support enamel health instead of fluoride.
Can I use it with my current toothpaste?
+
Absolutely. Tooth Armour is designed to layer over your existing toothpaste, making it one of the easiest oral care upgrades you can add to your routine. Simply drop it on, brush as normal, and you're done.
Is it suitable for sensitive teeth?
+
Yes – it's specifically formulated to be appropriate for sensitive teeth. The nano-hydroxyapatite works over time to help support and protect exposed dentine. If you have severe or sudden dental sensitivity, we recommend consulting your dentist first.
How long until I notice a difference?
+
Many customers report that their teeth feel more comfortable and smoother within the first 1–2 weeks of daily use, with continued improvement as enamel support builds over time. Individual results vary depending on your oral health and habits.
Can I use it alongside whitening products?
+
Yes. Tooth Armour pairs well with whitening toothpastes or treatments and can actually help support enamel comfort alongside them. Just follow each product's instructions and your dentist's guidance.
