Larineco does not publish a per-piece dose or a particle size, publishes 0 downloadable documents, and states a 30-day guarantee limited to the first purchase per household. Underbrush does not publish a per-piece dose or a particle size either, publishes 0 downloadable documents, and sells the gum as final sale with a guarantee available only through a paid add-on. Every cell above is what each brand states publicly, nothing is scored on taste or opinion; where a cell says not disclosed or not found, the figure could not be located in the brand’s own materials on the date checked.
This comparison is generated from the Hydroxyapatite Gum Database, maintained by Minvelle. We sell a gum in this category and appear in the same database under identical rules, which is exactly why every cell here is sourced instead of scored.
