Quick answer: Yes, for most people a tongue scraper is a worthwhile two-minute addition to your routine. Evidence shows tongue scraping can reduce the bacteria and volatile sulphur compounds associated with bad breath, and may do this more effectively than brushing your tongue alone.
Tongue scraping is an ancient Ayurvedic practice, where caring for the mouth is considered an important part of caring for digestive health.
We’re not going to tell you tongue scraping is a miracle cure or that it will “detox” your body. But it is a wonderfully simple, low-waste habit that helps remove the coating that builds up on your tongue.
For us, that makes a reusable tongue scraper well worth its place beside your toothbrush.
Below, we answer the questions people most often ask about tongue scraping.
What does a tongue scraper actually do?
Have a look at your tongue first thing in the morning. That whitish or yellowish coating you may see is a mixture of bacteria, dead cells and food debris that has accumulated on its surface.
A tongue scraper is simply a small curved tool that you gently draw from the back of your tongue towards the tip to lift some of that coating away.
Why does that matter? Bacteria living on the tongue can produce volatile sulphur compounds (VSCs), which are one of the major causes of bad breath.
Tongue scraping can be particularly worthwhile if you notice:
- morning breath
- a white or yellow coating on your tongue
- bad breath despite brushing and flossing well
- that brushing your tongue doesn't seem to remove much of the coating
Brushing your tongue with a toothbrush can help too, but a purpose-made scraper has a broad, smooth edge designed specifically to lift the coating from the surface of the tongue.
And we like that it is such a simple solution. Rather than continually reaching for a strongly flavoured synthetic mouthwash to mask bad breath, you're physically removing some of the bacteria and debris sitting on the tongue.
Do tongue scrapers actually work?
Yes, there is evidence that tongue cleaning can help reduce the bacteria and compounds associated with bad breath.
A Cochrane systematic review — an independent review that examines the available clinical research on a health question — found tongue scrapers and tongue cleaners reduced volatile sulphur compounds (VSCs) compared with brushing the tongue alone. In one included trial, reductions were around 40% with a scraper versus 33% with a toothbrush. The research is relatively small, but it supports tongue scraping as a simple addition to your oral care routine.
Is a tongue scraper actually necessary— and should I use one?
For most people, we think it's worth trying — particularly if you experience tongue coating or bad breath. It's not essential the way brushing and cleaning between your teeth are, but it does something they don't do as well: removing the coating that builds up across the surface of your tongue.
If your breath is fine and your tongue looks pink and clean, you can skip it.
What might you notice after tongue scraping?
- Fresher breath: usually the most noticeable change, particularly first thing in the morning.
- Less tongue coating: a whitish or yellow-coated tongue may look cleaner and pinker with regular use.
- Taste: some people report food tasting more vivid once a heavy coating is removed, although this is less well studied.
- A cleaner-feeling mouth: many people simply prefer how their mouth feels after removing the overnight coating.
What won't change? A tongue scraper won't whiten teeth, cure tonsil stones or fix bad breath that's coming from your gums, sinuses, digestion or a dental issue. If scraping doesn't shift persistent bad breath, that's worth mentioning to your dentist rather than scraping harder.
Can tongue scraping improve gut health?
This is where tongue scraping gets interesting. Your digestive tract begins in your mouth, which has its own community of microorganisms — the oral microbiome.
Every day we swallow saliva, and with it microorganisms from the mouth. Researchers are increasingly interested in the relationship between the oral and gut microbiomes, sometimes called the oral–gut axis, and how the movement of oral bacteria into the digestive tract may influence gut microbial balance.
Because tongue scraping removes some of the bacterial coating from the tongue before it is swallowed, there's an interesting link between this ancient practice and today's growing understanding of the oral microbiome.
So, can tongue scraping improve gut health? There's a plausible mouth–gut connection, but the research is still emerging. We don't yet have clinical trials showing that tongue scraping itself changes the gut microbiome, digestion or gut symptoms.
What we do know is that caring for your oral microbiome matters — and tongue scraping is one simple way to care for the very beginning of your digestive tract.
Why is tongue scraping used in Ayurveda?
Tongue scraping, traditionally known as jihva nirlekhana, has been part of Ayurvedic daily hygiene for centuries. It is traditionally practised first thing in the morning, using a metal scraper drawn gently from the back of the tongue to the front to remove the coating that has accumulated overnight. In Ayurveda, tongue cleaning forms part of dinacharya — a daily routine for maintaining health and hygiene.
What is the best material for a tongue scraper?
The three materials you'll most commonly come across are copper, stainless steel and plastic.
- Copper is naturally antimicrobial (meaning bacteria are less likely to colonise the tool between uses) and is the traditional material used for tongue scraping in Ayurveda. It's durable, reusable and can last for years with proper care. Copper naturally darkens or tarnishes over time — that's normal and not a reason to replace it.
- Stainless steel is durable, reusable and easy to clean. It won't tarnish like copper, and some designs have padded or contoured handles for comfort and control.
- Plastic is generally cheaper, but tends to wear out and need replacing more often. And, of course, it's plastic in the mouth, which many people prefer to avoid.

How do you use a tongue scraper properly?
There is absolutely no need to attack your tongue! Gentle, regular cleaning is the idea.
- Use it in the morning, before eating or drinking, when the coating is at its thickest.
- Stick your tongue out and relax it. Tensing your tongue can make gagging more likely.
- Place the scraper towards the back of your tongue, but only as far back as feels comfortable.
- Gently glide it forward towards the tip in one smooth motion. You're lifting the coating, not sanding your tongue.
- Rinse the scraper under running water after each pass.
- Repeat three or four times, moving slightly sideways each pass to cover the whole tongue.
- Rinse and completely dry your tongue cleaner before storing it.
How often should you use a tongue scraper?
Once a day is the sweet spot for most people, and morning beats night. Tongue coating builds up overnight as saliva flow drops, so first thing in the morning — before eating or drinking — is a good time to remove it.
A few gentle passes are enough. More isn't better — your tongue is living tissue, not a benchtop to be scrubbed clean. If your tongue looks clean, there's nothing more to scrape. Scraping too hard or too far back can cause gagging, irritation or small cuts, so keep it gentle and stop if you experience soreness or bleeding.
A tiny tool you'll use again and again
Our Biome Tongue Cleaner is made from pure copper in one simple, long-wearing piece, with a cotton bag for storing it at home or taking it travelling.
Tongue scraper FAQs
Can I use a spoon as a tongue scraper?
Yes — an upturned metal teaspoon works in a pinch. But a purpose-made scraper has a broader, curved edge designed to sit across the tongue, making it more comfortable and easier to control for everyday use.
Do dentists recommend tongue scrapers?
Yes, tongue cleaning is commonly recommended as an add-on to brushing and cleaning between your teeth, particularly for tongue coating and bad breath. It shouldn't replace either of those things or regular dental care.
Should I use a tongue scraper before or after brushing?
There's no need to make the order complicated. We like scraping first thing in the morning, followed by your usual brushing and oral-care routine.
How many times should I scrape my tongue?
Three or four gentle passes is enough. More pressure and more scraping are not necessarily better.
Can I use a tongue scraper every day?
Yes. Once a day is plenty for most people, provided your tongue remains comfortable.
Why use a copper tongue scraper?
Copper is durable, naturally antimicrobial and traditionally used for tongue cleaning in Ayurveda. We particularly like it because it gives us a simple, plastic-free tool that can be washed and reused over and over.
