The Importance of Tongue Cleaning for Oral Health

Oral health practices traditionally emphasize brushing teeth and flossing, but experts are increasingly advocating for the inclusion of tongue cleaning in daily routines. Dr. Maria Figueroa, a dentist and program director at NYC Health + Hospitals/Lincoln, asserts that cleaning the tongue is as crucial as maintaining dental hygiene. This practice can help mitigate issues such as bad breath and potential systemic health problems linked to oral bacteria.

Dental biofilm, a collection of bacteria and debris that accumulates on teeth, is distinct from the biofilm that forms on the tongue. Robert Shields, an oral microbiologist at the University of Florida College of Dentistry, explains that the tongue's unique structure, with its papillae, can harbor bacteria that may lead to gum disease and other health concerns. An overgrowth of bacteria on the tongue can produce compounds responsible for bad breath, highlighting the importance of tongue cleaning.

Experts recommend using a tongue scraper rather than a toothbrush for cleaning the tongue. Dr. Thomas Salinas, a prosthodontist at the Mayo Clinic, emphasizes that toothbrush bristles can be too harsh and may cause damage. He suggests using metal scrapers, such as those made of stainless steel or copper, as they are more effective and less likely to cause micro-scratches. Figueroa also supports the use of scrapers but acknowledges that toothbrushes with rubber scrapers can be convenient.

Cleaning the tongue should be integrated into daily oral hygiene routines, ideally twice a day, similar to brushing and flossing. Figueroa advises using a gentle raking motion to clean the front part of the tongue, which is generally manageable for individuals with a gag reflex. After cleaning, rinsing the scraper and allowing it to air dry is essential to prevent bacterial growth.

While tongue cleaning is endorsed by many dental professionals, there are concerns regarding overcleaning. Shields cautions that excessive cleaning may disrupt the oral microbiome by removing beneficial bacteria. This highlights the need for moderation in tongue cleaning practices.

Dr. Salinas emphasizes the importance of gentle cleaning, advising against excessive pressure to avoid damaging the tongue. He also suggests that individuals check their tongues for irregularities, which could indicate oral health issues such as cancer. “If you see any irregularities, you should definitely see a professional for evaluation,” he states.
