Crest Pro-Health mouthwash side effects
Tooth staining
Crest Pro-Health mouthwash contains Cetylpyridinium chloride which is known to cause tooth staining in approximately 3 percent of users. Crest has noted that this staining is actually an indication that the product is working as intended, as the stains are a result of bacteria dying on the teeth. Crest stated that because of the low incidence of staining, there was no need to label Pro-Health mouthwash as a potential tooth stainer. However, after numerous complaints and a federal class-action lawsuit, which was later dismissed, the mouthwash now contains a label warning consumers of its potential to stain teeth.

Reducing premature birth
The use of Crest Pro-Health mouthwash during pregnancy has been shown to be associated with a decrease in preterm births, presumably because the mouthwash reduces the severity of periodontal disease, which is directly linked to preterm births.
