Since you have managed pyorrhea (chronic periodontitis) for ten years, please be reassured that this condition can still be effectively controlled. Medications alone cannot cure it; they work best alongside professional dental cleaning (scaling). To manage the infection, your dentist may recommend: 1. Antiseptic mouthwashes containing chlorhexidine to control plaque bacteria. 2. Topical antibiotic gels (such as doxycycline or minocycline) applied directly into the gum pockets. 3. Oral antibiotics (like metronidazole or amoxicillin) if there is an active flare-up. Please visit a dentist for a professional deep cleaning and a tailored prescription plan to safely restore your gum health.
