A dirty tongue typically appears coated with a white or yellowish film.
Identifying a Dirty Tongue
A dirty tongue is characterized by a visible coating on its surface. This coating is primarily a buildup of various substances.
- White Coating: This is the most common sign and results from a buildup of bacteria, food debris, and dead cells. As Sarah points out, “This is caused by a build-up of bacteria, food debris and dead cells."
- Yellowish Coating: A yellow tint to the coating often indicates staining from substances like nicotine, tea, or coffee. Again, quoting Sarah, "It can also be yellow in colour, caused by nicotine, tea or coffee stains." This discoloration typically occurs when proper tongue cleaning is neglected.
The thickness and extent of the coating vary depending on individual oral hygiene practices and other factors. A heavily coated tongue might appear thicker and less pink than a clean tongue. The coating itself can be easily scraped away with a toothbrush or tongue scraper.
Causes of a Dirty Tongue
The primary cause of a dirty tongue is insufficient oral hygiene. Not brushing your tongue regularly allows bacteria, food particles, and dead cells to accumulate. Other factors can contribute to the appearance of a dirty tongue:
- Poor oral hygiene: Failure to brush and floss regularly.
- Dehydration: Reduced saliva production can lead to a drier mouth and increased buildup.
- Smoking: Nicotine stains discolor the tongue.
- Certain medications: Some medications can cause dry mouth.
- Medical conditions: In some cases, a heavily coated tongue can indicate underlying health issues, although this is less common.
