This professional toolkit summarises the evidence supporting the use of mouthwash as part of a preventive oral health strategy, helping dental teams make evidence-based recommendations for plaque management.

It brings together current research on mechanical and chemical plaque control, behaviour change and patient communication to support better periodontal health outcomes.

This guidance:

• Explains the role of mechanical plaque removal through toothbrushing and interdental cleaning as the foundation of oral hygiene.
• Reviews the evidence for adjunctive antimicrobial mouthwashes, including essential oils, chlorhexidine and other active ingredients.
• Provides practical advice on recommending mouthwash based on individual patient needs and clinical evidence.
• Highlights the importance of behaviour change techniques to improve patient adherence to daily oral care routines.
• Reinforces a preventive approach to reducing plaque, gingivitis and periodontal disease through effective home care.

For: Dentists, dental hygienists, dental therapists, dental nurses and other oral health professionals supporting patients with evidence-based preventive care.
