We recommend replacing the tongue scraper every four to six months, or sooner if it's showing signs of wear and tear.
The scraper should be replaced if:
* It's showing signs of wear and tear.
* It's missing its handle.
* It gets dirty from use.
* You or a family member develops a fungal infection.
A tongue scraper should be stored in a clean, dry place.
