Biom has re-branded and is now NOBS. The branding of the product you receive may differ.
NOBS isn’t just another toothpaste. It’s a smarter way to brush. Our formula uses 5% nano-hydroxyapatite (n-Ha), the same mineral your teeth are made of, to naturally strengthen enamel and support long-term oral health.
Backed by decades of dental research, n-Ha offers a proven, safe alternative to fluoride.
Why NOBS stands out:
Fluoride free, powered by 5% nano hydroxyapatite for enamel support
Low abrasive with an RDA of 21.38 to protect enamel while removing stains
Organic mint for lasting freshness without artificial sweeteners
Mess free tablets stored in airtight glass jars, not plastic tubes
Travel friendly and TSA approved with no liquid restrictions
Individually dosed tablets for zero waste and perfect portions
Xylitol - Kills the bad bacteria in your mouth (while saving the good guys!)
Mentha Piperita L (Peppermint) - For that fresh taste we love
Microcrystalline Cellulose - Helps keep your nobs bound together
Calcium Carbonate - Fights tooth staining
Sodium Lauryl Sulfoacetate - A much safer cleaning agent than what’s in your current toothpaste
Calcium Hydroxyapatite (Nanohydroxyapatite 5%) - Restores your enamel from everyday wear and tear
Silica Dioxide - Fights plaque and stains
Xanthan Gum - Improves the texture of your nobs when introduced to water
Sodium Cocoyl Isethionate Derived from Coconuts - Produces gentle foam
Ammonium Glycyrrhizinate (Licorice Root) - Fights bad breath
Menthol- Breath freshness that lasts
Zinc Citrate- Promotes healthy teeth and gums while preventing plaque buildup
Sodium Bicarbonate- Polishes teeth without being too abrasive
This product is not suitable for pets. Humans only, please!
While xylitol is great for supporting the human oral microbiome, it can be toxic to pets. Please keep NOBS away from your furry friends, and contact your veterinarian immediately if consumed by your pet.
For decades, fluoride dominated dental care. Every dentist recommended it. Every toothpaste contained it. But new research challenges this monopoly; especially regarding nano hydroxyapatite, a mineral your teeth are actually made of.
Here's what happens with regular toothpaste. Fluoride deposits foreign minerals into enamel, creating a harder surface. It works. No question there. But nano hydroxyapatite takes a different path. This synthetic mineral matches what's already in your teeth, calcium and phosphate. Instead of coating teeth with outside materials, it rebuilds them using their natural components.
Think of it like patching a wall. Fluoride adds a tough outer layer. Nano hydroxyapatite fills holes with the same material the wall's made from. Both fix the problem. One feels more natural.
Research backs this up. Studies comparing both ingredients find no real difference in cavity prevention. Both remineralize early decay. Both strengthen enamel. Both reduce sensitivity. The results? Nearly identical. Except for one crucial factor, safety profiles.
Fluoride's dark side emerges with overexposure. Dental fluorosis permanently stains teeth white or brown. Not just cosmetic, it signals systemic absorption. Pregnant women face bigger worries. Multiple studies link maternal fluoride intake to lower IQ scores in children. The evidence keeps mounting.
Then there's accidental swallowing. Kids do it constantly while learning to brush. A pea-sized amount of fluoride toothpaste contains enough fluoride to warrant calling poison control if swallowed. That warning label exists for good reasons.
Nano hydroxyapatite? Zero toxicity concerns. Swallow it, no problem. Your body recognizes it as calcium and phosphate, nutrients it needs anyway. No poison control calls. No fluorosis risk. No developmental worries. Just clean teeth without the anxiety.
Pregnant and nursing mothers top the list. Why risk fetal brain development when equally effective alternatives exist? Studies showing negative impacts on children's intelligence make this choice clear. Protect your baby's future cognitive abilities while maintaining your oral health.
Parents of young children appreciate the safety factor. Toddlers treat toothpaste like candy. They'll eat it given half a chance. Fluoride-free means one less thing to monitor. One less emergency to prevent. Brushing time becomes teaching time, not vigilance duty.
Anyone with sensitive teeth often finds better relief with nano hydroxyapatite. It fills microscopic tubules in dentin naturally. Many report faster improvement than with fluoride formulas. The mineral rebuilds rather than just hardening surfaces.
Health-conscious individuals avoiding unnecessary chemical exposure find their answer here. Why add fluoride to your body's burden when natural alternatives work just as well? Especially if you're already getting fluoride from water supplies.
Professional opinions shift as evidence accumulates. More dentists recommend nano hydroxyapatite, particularly for specific populations. They see the research. Same cavity protection. Fewer risks. Happy patients.
The remineralization data convinces skeptics. Side-by-side comparisons show virtually identical results. Early cavities heal. Enamel strengthens. Sensitivity decreases. But without fluorosis concerns or systemic effects. That's compelling for practitioners focused on "do no harm."
Some interesting bonuses appear too. Nano hydroxyapatite supports healthy oral bacteria better than fluoride. It physically blocks harmful bacteria from attaching to teeth. Less plaque formation. Better breath. Healthier gums. These weren't even the main goals, just nice surprises.
