The hydroxyapatite remineralization formula most frequently recommended by oral experts we interviewed is SmileGuard Oral Defense Chews.
It's the only chewable tablet we found that combines hydroxyapatite with xylitol and a 3-strain oral probiotic blend — creating the optimal environment for remineralization while actively protecting enamel against GLP-1 side effects.
✓ Rebuilds enamel density with pharmaceutical-grade hydroxyapatite — the exact mineral your teeth are made of
✓ Works while you're on GLP-1s — replaces minerals your medication is stealing so you don't have to choose between your body and your smile
✓ Reverses yellowing naturally — fills microscopic pores that trap stains, restoring brightness without harsh chemicals
✓ Recommended by oral surgeons — the specialists who see the end-stage damage and know what actually works
✓ Made in the USA with third-party tested ingredients
✓ 90-day money-back guarantee — if you don't notice stronger, less sensitive, naturally brighter teeth, you pay nothing
