Stop Sensitivity.
Rebuild Enamel.
Advanced nano-mineral formula that eliminates sensitivity, restores enamel, and brightens your smile — in one daily drop.

Four Problems.
One Daily Drop.
Most dental products treat symptoms. Orasub's nano-mineral complex works at the structural level — rebuilding enamel from the inside out.
Stop Tooth Sensitivity
Feel instant relief from hot & cold. Nano-hydroxyapatite molecules seal exposed dentinal tubules, creating a lasting protective barrier in minutes.
Rebuild Your Enamel
Restore and protect against daily damage. Nano-HA mimics the natural mineral structure of enamel, filling microfissures and restoring the tooth surface.
Strengthen Your Teeth
Make them more resistant over time. Daily remineralization increases enamel hardness and density, reducing fracture risk with every application.
Whiten & Brighten
Reveal a cleaner, more confident smile. Theobromine polishes and whitens while nano-silver keeps bacteria from re-staining the surface.
Science-Backed
Nano Minerals
Every ingredient is chosen for one purpose: rebuilding and protecting the structure of your teeth at the microscopic level.
Nano Hydroxyapatite
Bioidentical to tooth mineral. Binds to enamel surface, filling cracks and restoring hardness without fluoride.
Theobromine
A natural alkaloid that stimulates enamel remineralization and gently whitens. Found in cacao — clinically proven.
Nano Silver
Broad-spectrum antimicrobial that targets cavity-causing bacteria without disrupting the oral microbiome balance.
Trace Minerals
Zinc, magnesium, and calcium co-factors that amplify hydroxyapatite uptake and support overall enamel density.
Takes 60 seconds a day.
Orasub is designed to fit seamlessly into your existing routine — morning or night, after brushing.
Brush as Normal
Use your regular toothpaste and brush for 2 minutes to clear debris and plaque.
Apply Orasub
Dispense 2–3 drops onto your toothbrush or fingertip. Massage gently across all surfaces.
Let It Work
Leave on for 2 minutes. Spit — do not rinse. The formula continues absorbing for up to 4 hours.
Repeat Daily
Best results in 4–8 weeks. Many customers feel sensitivity relief within the first 3 days.
What Makes Orasub Special?
No harsh chemicals or artificial additives. Gentle on teeth and gums.
Remineralize enamel & balances oral microbiome's pH.
Anti-bacterial ingredients calm bleeding gums & kills harmful bacteria.
Removes plaque buildup & helps damaged enamel rebuild naturally.
How It Works
This isn't for people who love going to the dentist or trust corporate marketing. This is for those who know that real oral health should be easy & effective. This is for those who value easy remedies, honest healing, and the confidence of a healthy smile.
Hydroxyapatite is the same mineral that makes up your natural enamel. When used in toothpaste, it binds to the tooth surface, filling in micro-cracks and early lesions and helping rebuild lost mineral. Multiple clinical trials have shown that hydroxyapatite toothpastes can remineralize early caries lesions and prevent new ones, performing as well as—or non-inferior to—fluoride toothpastes in reducing caries activity and protecting enamel, without the toxicity concerns of high fluoride exposure.
Theobromine, a bioactive compound from cacao, has been shown in lab and clinical studies to increase enamel microhardness and support remineralization of early lesions. Compared with standard fluoride formulations, theobromine dentifrices and solutions have demonstrated significant improvements in surface hardness and mineral gain on demineralized enamel, making it a promising fluoride-sparing or fluoride-supporting ingredient for protecting teeth against acid attack.
Nanosilver (silver nanoparticles) provides a powerful, broad-spectrum antibacterial effect at very low doses. In mouthwash, varnish, and fluoride/nanosilver combinations, it has been shown to significantly reduce Streptococcus mutans, Lactobacillus species, and other cariogenic bacteria, lower plaque indices, and help prevent white spot lesions—especially around orthodontic brackets and in children with high caries risk. These effects make nanosilver a strong adjunct for controlling biofilm and supporting cavity prevention.
Xylitol is a natural sugar alcohol that cavity-causing bacteria like Streptococcus mutans cannot metabolize. Regular exposure (via gum, mints, or oral care products) has been shown to reduce S. mutans counts in saliva and plaque, lower acid production, and decrease new caries over time. Multiple randomized clinical trials show dose-dependent reductions in mutans streptococci and significantly fewer new caries lesions in people using xylitol products daily.
