Is diet soda better for teeth?
Less sugar, but not less acid. The ADA says sugar-free soft drinks can still erode enamel because carbonation raises acidity.
No toothpaste cancels out soda. The ADA names soft drinks, including sugar-free ones, as the major cause of dietary tooth erosion, because carbonation and citrus flavors make drinks acidic. Plain sparkling water is a much milder choice, and the ADA's MouthHealthy site calls it a mouth-healthy option.
What helps most is how you drink: with meals rather than sipped all day, followed by water. Klyyr One+ is a low-abrasion (RDA 62), fluoride-free hydroxyapatite paste. If erosion is already a concern, ask your dentist whether a fluoride toothpaste or rinse is a better fit.

Plain sparkling water is much less of a concern than soda, and MouthHealthy describes it as a mouth-healthy choice. Citrus-flavored versions are more acidic.
Advice differs. MouthHealthy suggests waiting an hour after acidic foods. A 2024 scoping review found weak evidence for waiting and noted fluoride toothpaste used right away did not add wear. Rinsing with water right after is agreed advice.

10% nano + micro hydroxyapatite, 0 ppm fluoride, no SLS, and all 16 ingredients listed.
One that's gentle (a low RDA) and that you'll use twice a day. If you already have erosion or cavities, ask your dentist about fluoride. One+ is fluoride-free with an RDA of 62.
No toothpaste restores enamel that has been lost. See can toothpaste reverse cavities.
MouthHealthy suggests using a straw if you drink soft drinks, and not swishing or holding the drink in your mouth.
Lab studies of other formulas have looked at hydroxyapatite and acid challenges. One+ does not claim to prevent erosion.
That's a different problem to raise with a doctor and dentist. See toothpaste for acid reflux.
