Is it true that dental care and cleanings can assist in reducing the amount of bacteria present in the mouth?
Yes. Dental care procedures such as professional cleanings, scaling, root planing, and interdental hygiene effectively reduce harmful bacterial loads and pathogens in the oral cavity.
Verdict: SUPPORTED · 4 sources for, 0 against · Last checked
The analysis
Multiple randomized controlled trials and systematic reviews demonstrate that dental cleanings and periodontal therapies significantly decrease the presence of pathogenic bacteria in the mouth.
Evidence for · 4
Demonstrates that scaling and root planing combined with sustained-release antiseptics effectively reduces pathogenic oral microflora.
