Periodontal surgery is a type of dental surgery used to treat advanced gum disease (also called periodontitis). It aims to clean deep pockets around teeth, repair damaged tissue, and help gums heal securely against teeth.
Key facts
Periodontal surgery is one of the most common dental surgeries performed to treat advanced gum disease. Millions of people worldwide have gum disease that may require surgical treatment at some point.
It mainly affects adults with long-standing or severe gum disease, especially those over 40. However, younger people with aggressive periodontitis may also need surgery. Smokers, people with diabetes, and those with a family history of gum disease are more likely to need this surgery.
A dentist or periodontist (gum specialist) examines your gums and teeth, checks for bleeding, and measures the depth of pockets around your teeth with a small probe. They may also take X-rays to see how much bone is left.
The exam is quick and usually not painful. The dentist will explain the health of your gums, show you any problem areas, and discuss whether surgery may be needed. You can ask questions and talk about options.
Periodontal surgery is one part of treatment for advanced gum disease. The main goal is to remove bacteria and tartar from deep pockets, smooth the tooth roots, and reshape gum or bone to make it easier to keep clean. Surgery is done after a thorough non-surgical cleaning.
After surgery, you will need to be gentle around the treated area for a few days. Your dentist will give you specific instructions about eating soft foods, avoiding strenuous activity, and rinsing with a special mouthwash. Follow-up visits are important to monitor healing.
After surgery, stick to soft foods (yogurt, soup, mashed potatoes) for a few days. Avoid hard, crunchy, or spicy foods that could irritate the surgical site. Return to normal eating gradually as healing allows. Exercise can resume after a day or two, but avoid heavy lifting or activities that raise your heart rate for the first few days.
You can reduce your risk of needing periodontal surgery by taking good care of your teeth and gums. Regular brushing, flossing, and dental check-ups are the most important steps. Avoiding smoking and managing conditions like diabetes also help.
Routine dental check-ups include screening for gum disease. Your dentist measures pocket depths and checks for bleeding at each visit, so early problems can be treated before they need surgery.
With proper treatment – including surgery when needed and good home care – most people can save their teeth and keep their gums healthy for many years. The outlook is very good, especially if you follow your dentist’s advice closely.

If symptoms are severe, worsening, or urgent, call your local emergency number or seek emergency care.
Non-surgical treatments include scaling and root planing (deep cleaning), antibiotics (oral or placed directly in gum pockets), and antimicrobial mouth rinses. If these are not enough, your dentist may recommend surgery: flap surgery (lifting gums to clean deeper), bone grafting (adding bone material), or guided tissue regeneration (using a special membrane to help bone grow back). All procedures are done under local anaesthesia. Your dentist will explain which type is best for your situation.
Surgery is considered when deep gum pockets (5 mm or more) remain after deep cleaning, or when there is significant bone loss that could lead to tooth loss.
Having gum surgery can feel stressful or worrying. It is normal to feel anxious about the procedure or about your teeth. Talking to your dentist or a counsellor can help. Many people feel better once they understand the benefits of surgery for saving their teeth.
