If you have periodontal disease, the peroxide doesn’t do any good- it doesn’t reach the anerobic bacteria in the pockets- brush and floss- mechanical debridement works best, see your dentist regularly.
In oral hygiene and dentistry, debridement refers to the removal of plaque and calculus that have accumulated on the teeth. Debridement in this case may be performed using ultrasonic instruments, which fracture the calculus, thereby facilitating its removal, as well as hand tools, including periodontal scaler and curettes, or through the use of chemicals such as hydrogen peroxide.
Is that some kind of kinky honeymoon procedure?
