Neem Mouthrinse

Reviewed by the Nimbera editorial team · Last updated May 2026

Chatterjee et al. (2011) double-blind RCT, n=45; neem (Azadirachta indica) mouthrinse was equally efficacious as 0.2% chlorhexidine for plaque-induced gingivitis with fewer side effects such as tooth staining (PMID 22368367).$6-$15 for a commercial neem mouthwash lasting 4-6 weeks.

How to use

Rinse with 10-15 ml of neem mouthwash for 60 seconds twice daily after brushing. Spit out completely. Alternatively, use a neem twig (datun) to brush teeth for 2-3 minutes then discard.

How it works

Neem contains nimbidin, nimbin, and gedunin - triterpenoids with demonstrated antibacterial activity against Streptococcus mutans, Porphyromonas gingivalis, and other periodontal pathogens. It also has anti-inflammatory properties that reduce gingival swelling.

Where to buy

Neem mouthwash at health food stores, Indian grocery stores, or online. Neem twigs (datun) available at Indian or African grocery stores.

Typical cost: $6-$15 for a commercial neem mouthwash lasting 4-6 weeks.

Safety notes

Do not swallow. Avoid neem oil taken internally during pregnancy - it is associated with adverse effects. Topical mouthrinse use is considered safe for most adults.
