While generally safe, tongue scraping should be approached cautiously by people with sensitive tongues, open sores, or oral infections, as it may cause irritation or worsen existing conditions if done improperly.

1. Individuals with Oral Lesions, Ulcers, or Sores

People with active oral lesions, such as canker sores, mucositis, or inflammatory conditions like oral lichen planus, should avoid tongue scraping until the tissue heals. Scraping can exacerbate irritation, cause bleeding, and delay healing by mechanically disturbing sensitive areas. The manual Oral Diagnosis and Treatment Planning highlights that excessive manipulation of inflamed or ulcerated tissues may increase susceptibility to bacterial infections and further mucosal damage. (45✔)

2. Patients with a Sensitive Gag Reflex

A strong gag reflex can make tongue scraping difficult or unpleasant, particularly when reaching the posterior (back) third of the tongue. This reflex is a protective mechanism, but for some individuals, it is hyperactive and can lead to nausea, vomiting, or anxiety during oral care. Dental Secrets, 4th Edition cautions that procedures involving the back of the oral cavity should be avoided or modified for patients with severe gag sensitivity. (46✔)

3. People with Severe Tongue Fissures or Depapillation

Individuals whose tongues exhibit deep fissures or have lost their natural papillae (depapillation) due to trauma, vitamin deficiency, or conditions like geographic tongue, are at risk of injury from scraping. The rough edges of scrapers may cause microtears or worsen fissures, allowing bacteria to penetrate deeper. Contemporary Geriatric Medicine describes how anatomical variations in elderly or compromised patients necessitate gentler oral care approaches. (47✔)

4. Critically Ill or Immunocompromised Individuals

Hospitalized patients, especially in ICUs or those undergoing chemotherapy, transplant, or immunosuppressive therapy, often have delicate oral environments. Scraping may pose a risk for introducing infections through microabrasions. Australian Critical Care emphasizes that oral care in critically ill patients must prioritize non-traumatic interventions to minimize sepsis risks. (48✔)

5. Elderly Patients with Dysphagia or Swallowing Disorders

Older adults with dysphagia (difficulty swallowing) may struggle to coordinate tongue movements or may inadvertently aspirate if scraping triggers a reflex. For these individuals, tongue care should be supervised and adapted. Research in the Journal of Oral Rehabilitation suggests that while tongue cleaning can support oral hygiene in elders, it should be done cautiously, especially when there are risks of aspiration or impaired motor control. (49✔)

How to Do Tongue Scraping Properly

Proper tongue scraping involves using a clean scraper to gently remove debris from the tongue’s surface. Doing it correctly ensures effectiveness, prevents irritation, and supports better oral hygiene every day.

4. Repeat the Motion 5–7 Times

Effective tongue scraping involves repeating the stroke 5–7 times, moving from the back to the front of the tongue. This repetition ensures thorough removal of biofilm and debris Lipat et al., 2018. (57✔) A single pass is insufficient for hygiene, while overdoing it may cause irritation Shieh et al., 2020. (58✔) Studies support consistent strokes as optimal for maintaining oral microbiome balance Izumi & Akifusa, 2021. (49✔)

5. Rinse Mouth and Scraper Thoroughly

After scraping, it’s crucial to rinse your mouth and clean the scraper to prevent reintroducing bacteria. Studies emphasize rinsing as a step that lowers residual bacterial count and supports long-term hygiene Torwane et al., 2019. (21✔) Scrapers themselves should be disinfected or rinsed after each use to avoid microbial growth Lipat et al., 2018. (57✔) Proper post-use cleaning improves both safety and efficacy Mosaico et al., 2024. (22✔)

Risks or Downsides of Tongue Scraping

Though tongue scraping is mostly safe, potential downsides include tongue irritation, over-scraping, and spreading bacteria if the scraper isn’t cleaned properly. It’s not a substitute for brushing or flossing.

1. Tissue Damage from Overuse

Excessive or forceful tongue scraping can lead to abrasions, inflammation, and tissue trauma, particularly on sensitive or dry tongues. Clinical updates advise moderation, as overuse may worsen oral conditions or cause discomfort. (59✔) Repeated trauma can trigger mucosal damage or leukoplakia in rare cases. (60✔) Health guides recommend gentle technique and limited repetitions to avoid harm. (61✔)

2. Triggering the Gag Reflex

For some individuals, especially those with heightened oral sensitivity, tongue scraping—particularly near the posterior third of the tongue—can induce an uncomfortable gag reflex. Studies show that oral care interventions must account for tactile triggers to reduce discomfort during hygiene routines. (62✔) Additional evidence links scraping depth with nausea or choking sensation. (63✔) Managing technique and depth helps minimize this risk. (64✔)

3. Risk of Infection in Open Lesions

Tongue scraping over existing oral ulcers or open lesions can damage mucosal tissue further, potentially leading to secondary infections. Clinical literature highlights that such trauma creates portals for microbial invasion. (65✔) Individuals with oral ulcers or mucosal inflammation are at greater risk of infection due to compromised epithelial barriers. (66✔) Experts recommend avoiding scraping until lesions heal to prevent worsening of inflammation or spread of infection. (67✔)

4. Not a Substitute for Other Oral Hygiene

While tongue scraping supports fresher breath and reduces microbial load, it cannot replace brushing, flossing, or mouthwash for complete oral care. A recent population study stresses that those using only tongue cleaning report higher rates of dental complaints. (68✔) Comparative data confirms brushing and flossing remain essential for caries and plaque control. (69✔) Experts agree: tongue scraping is an effective complement, not a core strategy.

5. Tool Contamination

Improper cleaning of a tongue scraper can lead to bacterial contamination, turning a hygiene tool into a source of microbial spread. Clinical studies highlight that reused, uncleaned scrapers can harbor biofilms and pathogenic bacteria. (21✔) Disinfection after each use is crucial to prevent reinfection. (70✔) Surveys also found that most users underestimate the need for daily scraper hygiene. (57✔)

Conclusion

Tongue scraping has gained significant attention in recent years due to its blend of ancient roots and modern wellness appeal. As more people prioritize holistic self-care and oral hygiene, this simple yet effective practice has emerged as a valuable addition to daily routines. With potential benefits like fresher breath, improved taste, and reduced bacteria, it’s no surprise that social media and wellness influencers have helped propel it into the spotlight.
