Baking soda dentifrice and periodontal health: A review of the literature

J Am Dent Assoc. 2017 Nov;148(11S):S15-S19. doi: 10.1016/j.adaj.2017.09.010.


Background: Mechanical disruption of dental biofilm is critical to maintain periodontal health. Baking soda-containing dentifrices have shown to be potential aids for improving gingival health and maintaining dental biofilm control.

Types of studies reviewed: Evidence from classic and contemporary literature is reviewed and summarized in this review. In vitro and in vivo (animal and human, respectively) studies and clinical trials have been analyzed.

Conclusions: Some clinical studies demonstrated the benefits of baking soda dentifrices in plaque and gingivitis reduction. Clinical trials with longer follow-up would be useful to confirm the impact of baking soda on gingival health.

Practical implications: Regular dental biofilm control and adjunctive use of baking soda dentifrices in an otherwise healthy and compliant patient may provide success in maintenance of gingival health.

Keywords: Sodium bicarbonate; baking soda; dental plaque; gingivitis; periodontitis.
