These products usually sold through dentists and just recently the manufacturer allows direct to consumer channel. I'm all in for promoting dental health as my relatives have issue with theirs, I guess I'm fighting the bad gene inheritance. Sharing these 2 products I personally use:
GC Tooth Mousse 2 for $35.90 delivered
This is the stuff dentists gave you at the end of your routine checkup. Basically to promote your teeth remineralization, works great for sensitive teeth. Bonus point that it tastes great :) (my pick is strawberry). Apply to your teeth and just leave it there, I do it at night before sleeping to ensure I'm not tempted to lick it clean. The active ingredient Recaldent/CPP-ACP was researched by the people from UniMelb. Here's from the horse's mouth, and plenty of research paper if you google around. Chemist Warehouse selling this for $25 each
Recaldent Chewing Gum 2 for $40 delivered
Using the same active ingredient CPP-ACP, but in a chewing gum. 112 Pellets per canister, mint flavour, sugar-free. Tub is bigger than normal chewing gum. I like the overall packaging as it has dual closing lid (full and small opening to dispense single pellet) and comes with a stack of wrapping papers for disposal, really neat. Made in Japan. Cheapest I could find online is $26.95 each.
Code can be used once per email address, and valid for purchases above $50 (before code). We also still stock 50 pcs TGA approved face masks for $37.42 delivered. Hope this helps someone.
