Root Surface Debridement (RSD)
Root Surface Debridement, commonly shortened to RSD, is a non-surgical treatment used to manage periodontal disease. It involves carefully cleaning beneath the gumline to remove plaque, hardened calculus and harmful bacterial deposits from the root surfaces of the teeth.
These deposits can collect inside deeper gum pockets where normal brushing and routine cleaning cannot reach. By thoroughly cleaning these areas, RSD aims to reduce inflammation, encourage healing and protect the bone and tissues that support your teeth.
Why might I need RSD?
- Deep periodontal pockets around the teeth
- Bleeding, swollen or tender gums
- Calculus deposits beneath the gumline
- Bone loss associated with periodontal disease
- Persistent bad breath or an unpleasant taste
- Loose teeth or changes in tooth stability
- Gum disease that has not improved with routine cleaning alone
How is RSD different from a routine scale and polish?
A routine scale and polish mainly removes plaque, calculus and staining from the visible surfaces of the teeth and around the gumline.
RSD is a more detailed treatment that focuses on the root surfaces inside deeper periodontal pockets. It is designed specifically for areas affected by gum disease and may require more time, local anaesthetic and several appointments.
What happens during treatment?
The treatment areas will first be assessed using your periodontal measurements and previous examination findings. Local anaesthetic may be used to numb the gums and allow the root surfaces to be cleaned thoroughly and comfortably.
Specialist hand instruments and powered ultrasonic equipment are then carefully passed beneath the gumline. Plaque, calculus and bacterial deposits are removed from the affected root surfaces and periodontal pockets.
Depending on the extent of the gum disease, the treatment may be completed in one appointment or divided into separate areas of the mouth over several visits.
Will RSD hurt?
Local anaesthetic is commonly used to minimise discomfort during treatment. You may still feel pressure, vibration or movement, but you should not experience sharp pain.
Once the anaesthetic wears off, the gums may feel tender or sensitive for a short period. Mild soreness is common and should gradually improve as the tissues begin to heal.
What can I expect afterwards?
- Mild gum tenderness or bleeding
- Temporary sensitivity to hot or cold
- Some gum shrinkage as inflammation reduces
- Teeth appearing slightly longer
- Spaces between the teeth becoming more noticeable
These changes do not usually mean that the treatment has damaged the gums. They often occur because swollen and inflamed tissue is healing and beginning to fit more closely around the teeth.
When will I see an improvement?
Bleeding, swelling and tenderness may begin to improve as the gums heal. However, the full response cannot be judged immediately because the periodontal tissues need time to settle after treatment.
A periodontal review will normally be arranged after an appropriate healing period. At this appointment, the gum pockets and bleeding levels may be measured again and compared with your previous records.
Will I need further treatment?
This depends on how your gums respond. If the inflammation and pocket depths have reduced, you may move into a personalised periodontal maintenance programme.
If deeper or bleeding pockets remain, selected areas may require further cleaning, closer monitoring or referral for more advanced periodontal treatment.
How can I support healing at home?
- Brush thoroughly twice each day using fluoride toothpaste
- Clean between every tooth using the recommended interdental brushes or floss
- Follow the personalised cleaning instructions provided to you
- Avoid smoking, as it can slow healing and increase the risk of further periodontal damage
- Attend all recommended review and maintenance appointments
- Contact the practice if you develop severe pain, swelling or persistent bleeding
Can RSD cure gum disease?
RSD can significantly reduce the bacteria and inflammation associated with periodontal disease, but it does not permanently remove the risk of the condition returning.
Long-term success depends heavily on effective daily cleaning, regular professional maintenance and controlling risk factors such as smoking and poorly controlled diabetes.
Protecting the foundations of your smile
RSD is designed to create a cleaner and healthier environment beneath the gums. Combined with consistent home care and ongoing monitoring, it can help stabilise periodontal disease and protect your natural teeth over the long term.
