The Claim

The absolute quantity of Rothia cells in subgingival plaque increases significantly after non-surgical periodontal treatment in patients with periodontitis, and this increase is strongly correlated with the overall recovery of nitrate-reducing bacteria, indicating that Rothia may serve as a biomarker for nitrate-reducing microbial function.

In plain English

After non-surgical periodontal treatment in patients with periodontitis, the number of Rothia bacteria in plaque rises, and this rise is closely linked to the return of nitrate-reducing bacteria.

See the scientific wording

The absolute quantity of Rothia cells in subgingival plaque increases significantly after non-surgical periodontal treatment in patients with periodontitis, and this increase correlates strongly with the overall recovery of nitrate-reducing bacteria, suggesting Rothia may serve as a biomarker for nitrate-reducing microbial function.

Why this might work

After dental cleaning, beneficial bacteria that convert nitrate into nitrite return to the gums, and one of these bacteria, Rothia, becomes more abundant. As these bacteria grow, they produce more nitrite, which enters the bloodstream and turns into nitric oxide. This nitric oxide kills harmful bacteria in the gums and reduces inflammation, helping the gums heal. The rise in Rothia matches the return of this healing process, so it acts like a signal that the mouth’s natural repair system is working.

  1. Study: Nitrate reduction capacity of the oral microbiota is impaired in periodontitis: potential implications for systemic nitric oxide availability

    After dental treatment, good bacteria that turn nitrate into nitrite come back in the mouth, and Rothia is one of those helpful bacteria — so when they increase, it means the mouth’s metabolism is healing.
