Suits say gum health toothpastes hide an irritating ingredient
Cassandra CampbellEditor
Two proposed class actions in California, against Procter & Gamble and Haleon, say Crest Pro-Health gum lines, Sensodyne, and Parodontax use sodium lauryl sulfate (SLS) without disclosing research linking it to gum irritation and slower healing. The shoppers argue that conflicts with marketing that promises healthier gums. No company response was reported, and the claims are unproven.
Why it matters
SLS is the same foaming agent found in many cleansers and shampoos, so it's worth knowing what it does and why some people choose SLS-free.
