The safety profile of any dentifrice depends heavily on how it treats gum tissue and mechanical enamel wear. One of the quiet victories of the NOBS tablet formula is its low abrasivity. Toothpaste safety is measured using the Relative Dentin Abrasivity (RDA) index:

• Low abrasivity (safe for exposed roots, sensitive dentin, and thin enamel)
• Medium abrasivity (standard commercial baseline)
• High abrasivity (aggressive stain removal)
• Harmful threshold (can strip cementum and damage enamel over time)

Many DIY recipes, charcoal powders, and unrefined chewable tabs rely on crushed silica or rough calcium carbonate, pushing RDA levels well past 110. Biom NOBS tablets score between 25 and 35 on the RDA scale. This makes the paste gentle on vulnerable gumlines, soft roots, and ceramic veneers.

The formula also targets the oral microbiome through chemical balance rather than antimicrobial carpet-bombing. Traditional mass-market pastes rely on sodium lauryl sulfate for that thick, familiar lather. SLS strips natural oral mucin layers, a frequent cause of recurring aphthous ulcers (canker sores) and dry-mouth flare-ups.

NOBS drops SLS entirely, substituting it with coconut-derived sodium cocoyl isethionate, which creates a modest, creamy froth that rinses clean. The recipe features a substantial dose of xylitol, a five-carbon sugar alcohol. Cariogenic bacteria like Streptococcus mutans consume xylitol but cannot digest it, which gradually starves the bacteria and prevents them from anchoring to tooth surfaces as sticky plaque.

Paired with sodium bicarbonate to buffer mouth acids and zinc citrate to neutralize volatile sulfur compounds responsible for halitosis, the chemical framework is well balanced. It avoids unnecessary dyes, parabens, and synthetic binders.
