Q
Dr. B, how important is it to clean your tongue? I’ve seen tongue scrapers at the drugstore but am wondering if they really help.
A
Brushing and flossing are essential for oral health, but cleaning your tongue is an often overlooked step that makes a meaningful difference. Using a tongue scraper is a simple, painless habit that helps keep your mouth cleaner, improves taste, and reduces bad breath.
Many people find the sensation of a freshly scraped tongue pleasant and notice that flavors come through more clearly once the coating is removed.
What is a tongue scraper?
A tongue scraper is a tool made to remove bacterial buildup, food debris, yeast cells, and dead cells from the surface of the tongue. That buildup contributes to common oral problems, so removing it is important for overall oral health.
Tongue scrapers come in several styles and are inexpensive; they’re available at drugstores and grocery stores and are sometimes provided by dental offices. Plastic scrapers are convenient and often disposable, while stainless steel scrapers are easy to clean and eliminate exposure to plastics.
Some people prefer stainless steel for its durability and hygienic properties.
Why is it important to clean your tongue?
Essential to oral health. Cleaning the tongue, especially the back portion, removes bacteria and toxins that contribute to plaque, tooth decay, and gum disease.
Enhances taste. A coated tongue can block taste buds. Removing debris exposes taste receptors and improves flavor perception.
Supports immunity. Removing bacterial and food buildup reduces the chance of toxins being reabsorbed. This is particularly helpful when you’re ill, since more debris can accumulate at that time.
Aids digestion. Tongue scraping stimulates saliva production, which helps break down food and supports digestion.
Reduces bad breath. A large proportion of halitosis originates from the back of the tongue, where food particles, bacteria, fungi, and dead cells collect. While the front of the tongue may look clean, the deeper coating farther back is often the source of unpleasant odors.
An easy way to picture it: the tongue’s surface resembles a carpet of mushroom-like taste buds that trap tiny particles from food and drink. These trapped particles don’t rinse away with regular mouthwash or brushing, so scraping helps remove them and the bacteria they feed.
How do you use a tongue scraper?
1. Stick your tongue out slightly and open your mouth to make the surface easier to reach.
2. Hold the scraper by its ends and place it toward the back of the tongue. You may trigger a gag reflex at first; this usually diminishes with practice, allowing you to scrape farther back over time.
3. Gently pull the scraper from the back of the tongue to the front in one smooth stroke. The scraper will collect debris on its edge as it moves forward.
4. You may notice a yellowish or clear coating on the scraper if you haven’t cleaned your tongue recently. With regular scraping the material will become less noticeable. Start daily if your tongue is heavily coated, then adjust frequency to every few days or weekly as needed.
What are the benefits of tongue scraping?
- Substantially reduces bad breath by removing food particles and bacteria that produce volatile sulfur compounds (VSCs), which cause foul odors.
- Effectively treats a coated tongue, which can result from bacterial or fungal colonization and trapped dead cells and debris.
- Helps resolve taste disturbances by clearing the material that clogs and obstructs taste buds, including metallic tastes.
- Restores a healthier tongue color by removing stains and buildup.
If bad breath persists despite tongue scraping, regular brushing, and flossing, consult your dentist. Persistent halitosis can signal a more serious underlying issue.
