What does Ayurveda say about tongue scraping?

Dinacharya is the Ayurvedic daily routine, a set of self-care steps meant to be done each morning. Classical texts describe several oral hygiene practices within it: dantadhavana (cleaning the teeth, traditionally with herbal twigs or powders), jivha lekhana or nirlekhana (scraping the tongue), and kavala and gandusha (holding or swishing liquids such as oil in the mouth). You will also see the term jihwa prakshalana in some modern guides for tongue cleansing.

Tongue scraping is usually done first thing after waking, before eating or drinking, to remove the coating that builds up overnight.

Reviews of Ayurvedic oral care describe tongue scraping as removing bad odor, improving taste, stimulating the tongue's "reflex points" and supporting digestion. In Ayurvedic thinking, the tongue coating is read as a sign of ama, residue from incomplete digestion, and its color and thickness are used as clues to imbalance.

Traditional sources favor metal scrapers. A 2014 review of Ayurveda in oral health lists gold, silver, copper and stainless steel as suitable materials.

So the practical part of the tradition, cleaning the tongue each morning, holds up reasonably well. The explanations around it do not.

Kavala and gandusha, swishing oil in the mouth, are often paired with tongue scraping. Ayurvedic texts make broad claims for them, including effects on many systemic diseases. Clinical reviews find only small, short trials, with possible reductions in saliva bacteria and no clear effect on plaque or gums. The ADA does not recommend oil pulling as a dental hygiene practice. If you include it, follow our safe how-to steps and read about the rare risks.

Copper is the material most associated with Ayurvedic tongue scraping, often promoted as antimicrobial. No trial shows a copper scraper cleans the tongue better than a steel one. The few seconds a scraper spends on the tongue matter less than the edge, the reach and how often you use it. Copper tarnishes and needs polishing. Stainless steel does not tarnish and can be boiled or put in the dishwasher. Both fit within the tradition, which includes stainless steel among acceptable materials. Our copper vs stainless steel comparison goes into more detail.

1. On waking, scrape your tongue from back to front, two to five gentle passes, rinsing the scraper each time.
2. Optionally, oil pull for 5 to 20 minutes, then spit into the trash.
3. Rinse with water.
4. Brush with fluoride toothpaste for two minutes and clean between your teeth.
5. Drink a glass of water.

This keeps the parts of the tradition with some evidence and adds the parts modern dentistry knows work. For technique, see how to use a tongue scraper.
