The tongue is the largest bacterial reservoir in the mouth. Its surface is covered with papillae, between which bacteria, food particles, and dead cells accumulate. Studies show that 60-80% of halitosis (bad breath) cases are linked to tongue coating.
How to clean your tongue properly
Tongue cleaning is best done in the morning, before breakfast.
- Stick your tongue out as far as possible.
- Place the scraper or brush on the back third of the tongue.
- Pull forward 3-5 times, rinsing the tool after each stroke.
- Do not press too hard.
Scraper or toothbrush?
Tongue scraper (Zungenreiniger): removes coating more effectively than a toothbrush. Available in stainless steel, copper, or plastic.
Toothbrush: the textured back pad can be used, but is less effective than a scraper.
White tongue coating: when to see a dentist
A thin white coating is normal. A thick coating that does not come off, colour changes, or painful spots are reasons to see a dentist. These may be linked to candidiasis, antibiotic use, or dehydration.
Tongue and overall oral health
Bacteria on the tongue contribute to plaque formation and gingivitis. A tongue scraper costs very little and is available at any pharmacy (Apotheke) or drugstore (dm, Rossmann) in Germany.
