Materials

• Copper (100%) — Body (Cu, atomic number 29)
  Pure copper, formed from a single piece with no joints, welds, or solder. Copper is one of the few metals with intrinsic antimicrobial properties — copper ions (Cu²⁺) disrupt bacterial cell membranes on contact, generate reactive oxygen species, and damage microbial DNA. This mechanism, called ‘contact killing’, was demonstrated by Grass et al. (2011) and is the reason hospitals install copper door handles, bed rails, and touch surfaces to reduce MRSA and C. difficile transmission. The same property works on the bacterial biofilm coating your tongue. Unlike chemical antimicrobials, bacteria cannot develop resistance to copper’s physical mechanism. The scraper is uncoated — no lacquer, no sealant — so the raw copper surface is always active. It develops a natural patina over time; this is cosmetic oxidation and does not reduce effectiveness.

What we left out

• Nickel plating (Coatings)
  Common on cheap scrapers. Nickel is the most common contact allergen in the EU — responsible for 15–20% of contact dermatitis cases (Thyssen & Menné, 2010). Putting nickel-plated metal on your tongue daily is a sensitisation risk. Ours is pure copper, nothing else.
• Chrome plating (Coatings)
  Decorative chrome plating involves hexavalent chromium (Cr VI) during manufacturing — a known human carcinogen (IARC Group 1). The finished plating is trivalent chromium, but scratches or wear can expose underlayers. Unnecessary on copper, which is already antimicrobial.
• Plastic grips (Handle)
  Some scrapers add TPE rubber or polypropylene grips for ‘comfort’. These harbour bacteria in crevices, can’t be sterilised, and add petrochemical materials to a product that goes in your mouth. This is one solid piece of copper — no joints, no crevices, nothing to trap bacteria.
• Soldered joints (Construction)
  Some copper scrapers are made from copper sheet soldered or welded together. Solder typically contains tin-lead or tin-silver alloys. Our scraper is a single formed piece — no solder, no joints, no secondary metals.
• Lacquer coating (Surface treatment)
  Some copper products are lacquered to prevent tarnishing. The lacquer is typically polyurethane or nitrocellulose — synthetic coatings that seal in copper’s antimicrobial properties and add a petroleum-derived film. We leave the copper raw so the antimicrobial action works.

Why we built it this way

• 100% pure copper — no plating, no coatings, no mixed metals, no alloy
• Antimicrobial — copper ions disrupt bacterial cell membranes on contact (Grass et al., 2011)
• One solid piece — no joints, no solder, no glue, nothing to harbour bacteria
• Buy-once product — copper is extremely durable. No bristles to wear out, no cartridges to replace
• Tongue scraping reduces bad-breath VSCs by 75% — vs 45% for brushing alone (Pedrazzi et al., 2004)
• Bacteria cannot develop resistance to copper — unlike antibiotics, copper’s mechanism is physical, not chemical
• 3,000+ years of Ayurvedic oral hygiene tradition — modern research confirms the mechanism (Grass et al., 2011)
• 10 seconds a day — the single most effective mechanical intervention for halitosis
• No nickel, no chrome — nickel is the most common contact allergen in the EU (Thyssen & Menné, 2010)
• Uncoated — no lacquer sealing in the antimicrobial surface. Raw copper, active on contact

How to use

1. Stick your tongue out
   As far as comfortable. You want to reach the back — that's where most bacteria live.
2. Place the scraper at the back
   Hold both ends. Press the curved edge gently against the back of your tongue.
3. Pull forward 5–10 times
   Gentle, even pressure. You'll see a whitish coating on the scraper — that's the bacterial biofilm.
4. Rinse and dry
   Rinse the scraper under running water after each pull. Pat dry when done. That's it — 10 seconds.

FAQ

Does tongue scraping actually work?

Yes. Pedrazzi et al. (2004) found tongue scraping reduced volatile sulphur compounds — the molecules that cause bad breath — by 75%, compared to 45% for brushing alone. The tongue dorsum is the largest bacterial reservoir in your mouth. Brushing doesn’t reach it effectively.

Copper vs stainless steel tongue scraper — which should I choose?

We make both, and both are solid metal, plastic-free, and fully disclosed — the difference comes down to one property. Copper is naturally antimicrobial: copper ions kill bacteria on contact within minutes, where on a non-antimicrobial surface they survive far longer (Grass et al., 2011). It develops a patina over time and takes an occasional lemon-juice wipe to keep its shine. Our stainless steel scraper isn’t antimicrobial, but it’s completely maintenance-free — it never tarnishes and takes a dishwasher cycle. If the antimicrobial surface is the point for you, choose copper; if you want zero upkeep, choose the stainless steel scraper. One thing to watch whichever you pick: many scrapers sold as ‘copper’ are actually copper-plated steel or alloy, and the plating wears off within weeks — this one is a single piece of solid copper, never plated.

Will it turn green?

Copper develops a natural patina (verdigris) over time — that’s surface oxidation. It doesn’t reduce the antimicrobial effect. Clean with lemon juice and salt if you prefer the shine. The patina is cosmetic, not functional.

Is it safe to put copper in your mouth?

Yes. Copper is an essential dietary mineral — your body needs 0.9mg per day (RDA). The trace amounts transferred during 10 seconds of tongue scraping are negligible compared to dietary intake from food and water. Copper has been used in oral hygiene for thousands of years across multiple medical traditions.

How often should I scrape my tongue?

Once a day, ideally in the morning before eating or drinking. The bacterial biofilm on your tongue accumulates overnight. Ten seconds of scraping removes it. Some people scrape morning and night — both are fine.

How often should I replace it?

You probably won’t need to. Copper is extremely durable. There are no bristles to wear out, no plastic to crack, no filters to change. This is a buy-once product. It will outlast you.

Can I use it with braces or dental work?

Yes. The scraper touches only the tongue surface, not your teeth. It won’t interfere with braces, retainers, crowns, or implants.

Does tongue scraping help with bad breath?

It’s the single most effective mechanical intervention for halitosis. Volatile sulphur compounds (VSCs) — the molecules responsible for bad breath — are produced by anaerobic bacteria living in the biofilm on your tongue. Brushing your teeth removes plaque from enamel but doesn’t address the tongue biofilm. Scraping does.

Research

• Grass G, Rensing C, Solioz M (2011). Applied and Environmental Microbiology
  Metallic copper surfaces kill bacteria within minutes through a mechanism called contact killing. Copper ions disrupt bacterial cell membranes, generate reactive oxygen species, and damage DNA. This antimicrobial property is intrinsic to the material and does not diminish with use — unlike chemical disinfectants, copper’s antibacterial action is a permanent physical property of the metal.
• Pedrazzi V, Sato S, de Mattos MG, Lara EH, Panzeri H (2004). Journal of Applied Oral Science
  Tongue scraping reduced volatile sulphur compound (VSC) levels by 75%, compared to 45% for tooth brushing alone. Tongue cleaning is the single most effective mechanical intervention for halitosis. The dorsum of the tongue harbours the largest reservoir of anaerobic bacteria in the oral cavity.
• Sathiyaseelan A, Saravanakumar K, Mariadoss AVA, Wang MH (2021). Journal of Environmental Chemical Engineering
  Copper nanoparticles exhibited broad-spectrum antimicrobial activity against both Gram-positive and Gram-negative bacteria. The mechanism involves disruption of the bacterial cell wall, generation of reactive oxygen species, and interference with cellular respiration. Unlike antibiotics, bacteria cannot develop resistance to copper’s physical antimicrobial mechanism.
• Quirynen M, Avontroodt P, Soers C, Zhao H, Pauwels M, van Steenberghe D (2004). Journal of Clinical Periodontology
  Tongue cleaning as part of a full-mouth disinfection protocol significantly reduced total bacterial counts in saliva by 1–2 log units. The tongue dorsum is the primary source of oral bacteria that recolonise tooth surfaces within hours of brushing.
