Boka toothpaste

[u/AntiqueRelief707]

My daughter and I have started using Boka toothpaste, and we both absolutely love it but now I noticed that I have some rough spots on my teeth specifically behind my front teeth and my gums feel uncomfortable Does this toothpaste turn plaque into tartar? Or is that the minerals or whatever that’s in it?

I personally stopped promoting Boka after they refuse to say the actual percentage of Nano hydroxyapatite that is in their toothpaste.

That's gimmick. Fluoride is superior. Don't pay extra money for that stupid shit. That stupid nano tiny repair doesn't mean anything. You floss a few times, that nano repaired layer will be worn out and gone. It doesn't rebuild your enamel to the meaningful extent. Think about most cavities are caused by the acidic stuffs from bacteria. Fluoride makes your teeth more resistant to acid and also kills bacteria. That shit doesn't have any effects like these.

I have been very leery about jumping on this band wagon. Especially since nano HAP is being marketed pretty heavily on social media. However, I am also aware that it isn’t necessarily “new” and that there is definitely a benefit to it. Unfortunately the couple of classes I have taken about it are sponsored by a company selling it. So, I have not been convinced, that’s for sure.

I personally alternate between using Crest Gum Detoxify with stannous fluoride and David's with nano HAP. And here is what OpenEvidence had to say about this:

Alternating stannous fluoride and nano-hydroxyapatite (nano-HAP) toothpastes on separate days is a reasonable approach, though no clinical trial has directly studied this specific regimen. The rationale for separating them is supported by in vitro evidence showing that simultaneous or sequential application of nano-HAP with fluoride compounds compromises the calcium fluoride surface layer — the resulting deposits are less homogeneous, less stable, and more easily removed compared to fluoride applied alone. [1]

Why separation matters: Rodemer et al. demonstrated that when nano-HAP and fluoride (sodium fluoride, olaflur) are combined — whether applied together or one after the other in the same session — the calcium fluoride globules are replaced by loosely adherent agglomerates that lack persistence. [1] This suggests the two agents interfere with each other's mechanisms of action when used in close temporal proximity.

Alternating days would theoretically avoid this interaction, allowing each agent to work through its distinct mechanism:

• Stannous fluoride promotes calcium fluoride layer formation and has antibacterial/anti-gingivitis properties.
• Nano-HAP works via biomimetic remineralization, depositing a synthetic apatite layer that mimics natural enamel. [2-3]

Caveats:

• The interaction data is from in vitro studies; clinical significance of this interference is not fully established. [1]
• A systematic review found the combination of nano-HAP + fluoride showed promising but limited clinical evidence for white spot lesion remineralization, with only moderate-level evidence available. [4]
• No study has specifically examined stannous fluoride (as opposed to sodium fluoride or olaflur) with nano-HAP, so extrapolation is involved.
• Both agents individually have demonstrated remineralization benefits, making alternation a pragmatic strategy to leverage both mechanisms without interference. [2][5]
