Scientific reviews highlight the need for care when selecting toothpaste, as certain products may cause oral mucosal irritation. Categories requiring caution include highly abrasive whitening pastes that can erode enamel, and fluoride-free versions, which increase the risk of decay. Activated charcoal toothpastes are also under scrutiny due to insufficient evidence supporting their safety and efficacy. Furthermore, some formulations contain irritants like sodium lauryl sulfate, while products claiming to remove tartar cannot replace professional cleaning. Experts recommend choosing fluoride-based toothpastes tailored to individual needs and seeking dental advice if symptoms like burning or redness occur.
