Periodontal maintenance involves routine professional cleanings and evaluations by a dental hygienist or periodontist to manage gum health in patients who have undergone previous periodontal treatment. This ongoing care is vital for preventing the recurrence or progression of gum disease. During these visits, plaque, tartar, and bacteria are removed from above and below the gumline, gum pockets are measured, and the overall condition of the gums and supporting structures is assessed. Regular maintenance helps preserve gum health, prevent further disease, and reduce the risk of tooth loss, promoting long-term oral health and a healthy smile.
