The speaker mentions switching to a hydroxyapatite-containing toothpaste and noticing whiter teeth. They state their dentist also confirmed stellar dental reviews since the switch.
"The speaker and many of the speaker's patients who have switched to hydroxy appetite toothpastes have noticed whiter and brighter teeth, better oral microbiomes, and healthier, stronger teeth. The speaker explicitly states that not all hydroxy appetite toothpastes are the same and one should be mindful of sourcing and ingredients."
