How to clean your tongue: do you need a tongue scraper?
October 19, 2026
Most people brush their teeth every day. But research has highlighted that only 18.4% of people practice daily tongue cleaning, suggesting it’s a neglected part of oral care. Yet your tongue is one of the areas where bacteria a, food particles and dead cells can collect.
Over time, this build-up can contribute to bad breath, altered taste and, in rare cases, infections, and may leave the tongue looking coated and/or white.
While tongue coating is commonly associated with an accumulation of bacteria, food debris and dead cells, persistent white patches or significant changes in tongue appearance may also be associated with underlying oral or medical conditions and should be evaluated by a dental professional.
The good news is that tongue cleaning is simple.
Whether you use a toothbrush or a tongue scraper, making tongue cleaning part of your routine can help support a cleaner, fresher-feeling mouth.
Tongue cleaning is one step in a broader daily oral care routine. Brushing your teeth, cleaning between teeth and rinsing all have a place too. The Dyson CameraJet™ electric toothbrush with flosser, Dyson Non-foaming toothpaste and Dyson Low-foaming mouth rinse can be used alongside tongue cleaning as part of that routine.
Whether you’re dealing with a white tongue, wondering if a tongue scraper is worth adding to your routine, or trying to understand what a sore tongue may be telling you, this guide explains what causes tongue build-up, how to clean your tongue effectively, and when it may be worth seeking professional advice.
How to clean your tongue
The simplest way to clean your tongue is to remove the coating that can build up on its surface. This can be done using either a toothbrush or a tongue scraper. Each method uses a slightly different technique.
Using a tongue scraper
A tongue scraper is designed specifically for tongue cleaning.
To use a tongue scraper:
Extend your tongue comfortably.
Position the scraper as far back on the tongue as you can without causing discomfort.
Using gentle pressure, pull the scraper forwards across the surface of the tongue.
Rinse the scraper after each pass.
Repeat three to five times, covering the width of the tongue.
Rinse the scraper thoroughly after use and allow it to dry completely.
Cleaning your tongue with a toothbrush
Many people also clean their tongue using a toothbrush as part of their daily oral care routine.
To clean your tongue with a toothbrush:
Place the toothbrush along the centre of the tongue as far back as is comfortable.
Avoid reaching the point that triggers a gag reflex.
Using light pressure, move the toothbrush forwards and backwards from the back of the tongue towards the tip.
Rinse the toothbrush to remove residue and repeat across the tongue's surface.
Finish by rinsing your mouth thoroughly with water.
When cleaning your tongue, use gentle pressure and avoid aggressive scraping or brushing, which may cause irritation.
If your tongue appears coated or you experience ongoing bad breath, including tongue cleaning in your daily routine may help. If symptoms persist or become a recurring concern, seek advice from a dental professional.
What is a tongue scraper?
A tongue scraper is a tool designed specifically to remove build-up from the tongue's surface.
Most tongue scrapers have a curved edge that is drawn gently across the upper surface of the tongue. As it moves across the surface, it lifts away tongue coating containing bacteria and food debris.
Because the tongue has a naturally textured surface, build-up can settle into tiny grooves and crevices. A tongue scraper is designed to remove this coating efficiently.
Tongue scrapers are usually:
Plastic, silicone or metal.
Small and lightweight.
Easy to clean.
Designed for daily use.
Many people use them as part of a broader oral hygiene routine alongside brushing, flossing and rinsing.
Tongue scraper: do you need one?
Not necessarily. A tongue scraper can be an effective way to clean your tongue, but it isn't the only option.
Both toothbrushes and tongue scrapers can be used to clean the tongue. Some individuals may prefer tongue scrapers for removing tongue coating, although consistent daily cleaning is generally considered more important than the specific tool used.
If you're choosing between methods:
A tongue scraper is designed specifically for tongue cleaning.
A toothbrush can clean the tongue while you brush your teeth.
Consistency matters more than the tool itself.
For most people, either approach can form part of a healthy oral care routine.
Why does tongue build-up happen?
Your tongue isn't smooth. Its textured surface creates places where bacteria, food particles and dead cells can accumulate.
This build-up can contribute to:
Altered taste.
In rare cases, oral infections.
Bad breath.
A coated tongue.
Changes in tongue appearance.
A less fresh feeling mouth.
Just as plaque can build up on teeth and along the gumline, bacteria can accumulate on the tongue if it isn't cleaned regularly.
That's why many dental professionals recommend cleaning your tongue alongside brushing and cleaning between your teeth.
What causes a white tongue?
A white tongue can develop for a number of reasons. In some cases, it may be caused by a build-up on the tongue's surface. In others, it can be a symptom of an underlying oral or health condition.
Causes that may be linked to tongue coating and oral hygiene
A white tongue is often caused by build-up accumulating on the tongue's surface.
This coating may consist of:
Bacteria.
Food debris.
Dead cells.
Material trapped within the tongue's natural texture.
A white tongue associated with tongue coating may sometimes be linked to:
Infrequent tongue cleaning.
Changes in oral hygiene habits.
In these situations, maintaining a consistent oral care routine, including brushing your teeth, cleaning between your teeth and cleaning your tongue, may help improve the appearance of the tongue. The UK’s National Health Service (NHS) notes that brushing your tongue or using a scraper may help improve a white tongue.
Causes that may require professional advice
Not all causes of a white tongue can be managed through tongue cleaning or changes to your oral hygiene routine.
A white tongue can also be a sign of an oral or systemic health condition, including:
Dry mouth.
Dehydration.
Anaemia.
Scarlet fever.
Lichen planus.
Geographic tongue.
Mouth ulcers.
Oral thrush.
These conditions require appropriate assessment and should not be self-diagnosed. The NHS explains that a ‘white tongue can be a sign of a health condition’, and stresses to ‘see a GP if you're worried.’
If your tongue appears white, it is important to understand the underlying cause rather than assuming it is related to tongue coating alone.
If a white tongue persists or changes significantly, it is important to seek advice from a dental professional.
What does a sore tongue mean?
A sore tongue can occur for a variety of reasons.
Common causes may include:
Minor irritation.
Accidental biting leading to ulcers.
Sensitivity to certain foods.
Dry mouth.
Friction from oral appliances.
Because there are multiple possible causes, a sore tongue isn't something that can be diagnosed based on appearance alone.
If soreness persists or becomes increasingly uncomfortable, professional advice is recommended.
‘Mouth sore tongue’: when should you seek advice?
The phrase ‘mouth sore tongue’ is often used to describe discomfort affecting the tongue or surrounding areas of the mouth.
You should speak to a dental professional if you experience:
Persistent mouth soreness/discomfort.
Trauma such as traumatic brushing or forced tongue cleaning.
White patches that don't improve with tongue cleaning.
Difficulty eating or drinking.
Professional assessment can help identify whether changes to your oral care routine are needed and rule out any underlying concerns.
The connection between tongue cleaning and bad breath
Halitosis, also known as bad breath, has a ‘has a worldwide prevalence ranging from 22% to 50%.’ Bad breath usually develops from the production of sulphur compounds as a result of bacterial break down of food debris. According to the NHS, the causes of bad breath include:
Eating or drinking spicy or strong-smelling foods and drinks
Problems with your teeth or gums, such as holes in your teeth, gum disease, or an infection.
Crash dieting or fasting.
Some medical conditions, like tonsillitis, dry mouth, and acid reflux
Smoking.
The most commonly missed areas while cleaning/brushing include:
Between teeth.
Along the gumline.
Across the tongue.
Because the tongue provides a large surface area where bacteria can gather, regular cleaning is often beneficial as part of a teeth cleaning routine designed to support fresher breath.
Tongue cleaning may help reduce tongue coating and support fresher breath as part of a complete oral hygiene routine.
A more complete approach to oral hygiene
Tongue cleaning is important, but it's only one part of oral health.
A complete routine should also include:
Brushing teeth thoroughly.
Cleaning between teeth.
Caring for your gums.
Maintaining hydration.
Using mouth rinse where appropriate.
Many people find cleaning between their teeth particularly difficult. That's why oral care routines increasingly focus on more than brushing alone.
Tongue cleaning can present its own challenge. Whether using a toothbrush or a tongue scraper, the gag reflex can make the process uncomfortable, leading some people to avoid it altogether.
The Dyson CameraJet™ electric toothbrush with flosser is designed around complete-mouth cleaning, combining brushing, cleaning between teeth and rinsing in one routine. For a more connected oral care experience, it can also be paired with Dyson non-foaming toothpaste, a formulation engineered for the Dyson toothbrush as part of a broader approach to daily oral hygiene, and Dyson Low-foaming mouth rinse.
When to reach out to a dentist
Most changes in the appearance or feel of your tongue are not necessarily a cause for concern. However, some symptoms should be assessed by a dental professional rather than managed through changes to your oral care routine alone.
You should consider seeking professional advice if you experience:
A white tongue that persists or changes significantly.
Ongoing bad breath that does not improve with regular oral hygiene.
Persistent tongue soreness or discomfort.
Difficulty eating, drinking or swallowing.
Recurrent mouth ulcers.
White patches that do not improve with tongue cleaning.
Unexplained changes in the colour, texture or appearance of the tongue.
Any ulcer, lump, red patch, white patch or unexplained change within the mouth that persists should be evaluated by a dental professional.
While daily oral hygiene plays an important role in supporting oral health, professional assessment can help identify underlying oral or systemic health conditions that may require further attention.
Fresh breath starts with complete-mouth cleaning
Cleaning your tongue doesn’t have to be complicated. Whether you choose a tongue scraper or simply use your toothbrush, including your tongue in your daily routine can help support better oral hygiene and a fresher-feeling mouth.
Complete-mouth cleaning also includes the teeth, gums and spaces between teeth. The Dyson CameraJet™ electric toothbrush with flosser, Dyson Non-foaming toothpaste and Dyson Low-foaming mouth rinse can form part of a routine that includes brushing, cleaning between teeth, rinsing and regular tongue cleaning.
