This article provides general recommendations based on published research and professional review. It does not diagnose or treat dental conditions.
While some water flossers show reductions in plaque and inflammation when added to brushing, they are not a substitute for professional advice or personalized clinical care.
Always consult your dentist or periodontist before changing your oral hygiene routine, especially if you have active periodontal disease.
