All the cavity protection and clean ingredient integrity of the Before fluoride range, reformulated for teeth and gums that need a gentler approach. Before's Sensitive SuperMint Anti-Cavity Toothpaste is built around potassium nitrate - a clinically proven desensitizing active that works by calming the nerves inside the tooth - alongside sodium fluoride for cavity protection and enamel remineralization, delivered in the same plant-based, organic-forward formula that makes Before stand apart from conventional oral care.
The formula maintains the clean standard across the board - organic xylitol, plant-derived foaming, arginine and zinc for microbiome support, organic aloe vera for gum health - while the lower-abrasion silica base and potassium nitrate active make it suitable for daily use on teeth and gums that react to temperature, pressure, or standard toothpaste formulations. Free of SLS, SLES, parabens, PEGs, hydrogen peroxide, and artificial flavours and colours. Dentist recommended, vegan, Leaping Bunny certified, gluten-free, and proudly made in Vancouver, Canada.
Who's It For
Anyone experiencing tooth sensitivity - to hot or cold temperatures, sweet foods, pressure, or general daily sensitivity - who wants a clean, effective toothpaste that addresses the problem without loading up on unnecessary additives. Well-suited to those with sensitive gums, recent dental work, or anyone whose current toothpaste is contributing to rather than relieving sensitivity through harsh foaming agents or high-abrasion formulas.
Flavour Profile
Ultra-cool, bold, and long-lasting. The SuperMint blend of peppermint oil, spearmint oil, and menthol delivers an intensely fresh, clean mint sensation that lingers well past the brush - bright, crisp, and invigorating without aggravating sensitivity.

Key Ingredients
Active Ingredients:
Potassium Nitrate (5%) - A clinically proven desensitizing agent that penetrates the tooth and calms the nerve endings responsible for sensitivity, reducing the pain response to temperature, pressure, and sweet foods with regular use. Sodium Fluoride (0.24%) - Clinically proven to strengthen enamel, prevent cavities, and remineralize early tooth decay.
Key Inactive Ingredients:
-
Xylitol (*Organic) - A natural sugar alcohol that actively inhibits the bacteria responsible for tooth decay while supporting a balanced oral microbiome.
-
Arginine - An amino acid that helps neutralize acids in the mouth, supports remineralization, and promotes long-lasting freshness between brushing.
-
Zinc Sulfate - Fights harmful bacteria, reduces plaque buildup, and supports healthy gum tissue.
-
Aloe Vera (Aloe Barbadensis Leaf Extract) (*Organic) - Soothes gum tissue, reduces inflammation, and delivers antioxidant support for overall oral health.
-
Peppermint Oil (Mentha Piperita) - Delivers the formula's primary bright, clean mint character with natural antibacterial properties.
-
Spearmint Oil (Mentha Spicata) (*Organic) - Adds a softer, slightly sweeter mint dimension that rounds out the SuperMint cooling profile.
-
Menthol (from Wild Mint Leaf) - Drives the long-lasting cool sensation that defines the SuperMint experience.
-
Glycerin (*Organic, from Mustard Plant) - A plant-derived humectant that keeps the formula smooth and comfortable on sensitive teeth and gums.
-
Cocamidopropyl Betaine (from Coconut Oil) - A gentle, plant-derived foaming agent that replaces SLS for a balanced lather that doesn't irritate sensitive oral tissue.
How To Use
Adults, adolescents, and children 2 years and older: Apply a pea-sized amount to a wet toothbrush. Brush teeth thoroughly for at least one minute, preferably after each meal or as directed by a dentist. Do not swallow. Children under 6 should use a pea-sized amount under adult supervision and be supervised to brush properly and not swallow. Should be used as part of an oral health program that includes regular flossing and dental check-ups. Consult a healthcare practitioner before use in children under 2 years of age. If sensitivity persists or worsens, consult a dentist.
How To Recycle
Carefully cut open and thoroughly rinse the inside of the tube. Confirm there is no toothpaste residue remaining. Place the tube and cap in your recycling bin.
Why MASC Recommends This
Most sensitive toothpastes address the symptom without doing much about the overall quality of what's in the formula - SLS, artificial additives, and synthetic flavours remain common even in products marketed at sensitive teeth and gums. This one takes a different approach: potassium nitrate and sodium fluoride handle the clinical brief, while the SLS-free, organic-forward base removes several of the common irritants that can quietly contribute to ongoing sensitivity. For anyone who has been reaching for a sensitive toothpaste without seeing meaningful improvement, upgrading to a cleaner formula is often a worthwhile variable to change.
