Non Surgical Periodontal TreatmentsNon-surgical therapy is considered effective in getting rid of calculus and plaque by restricting the growth of harmful bacteria and by remedying the conditions that promote gum disease in patients. It’s the kind of treatment that may be appropriate enough for specific patients— especially when periodontal disease is detected early. Additionally, a patient may have to undergo some non-surgical procedures such as replacement of worn fillings, which can accrue plaque, before periodontal therapy is initiated.
