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

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.
