Scaling and root planing is a deep clean that treats gum disease below the gumline, and it is the recognised first line, non surgical treatment for established gum disease. Unlike a routine clean, which mostly works above the gum, this procedure reaches into the spaces between the gum and the tooth root to remove the hardened plaque and bacteria driving the disease. The single thing that decides whether you need it is the depth of the pockets around your teeth, which your dentist measures with a small probe.
Key takeaways
- Scaling and root planing is a deep clean below the gumline, not a routine polish.
- It is the standard first treatment for gum disease, also called periodontitis.
- It removes hardened plaque and smooths the root so the gum can reattach.
- Evidence shows it reduces pocket depth and helps gums heal, especially in moderate cases.
- It is usually done with numbing and may be split across more than one visit.
How is it different from a normal clean?
A regular dental clean removes plaque and tartar mainly from the visible surfaces above the gumline and keeps healthy gums healthy. Scaling and root planing goes deeper. Scaling removes the hardened deposits from below the gum, and root planing smooths the root surface so bacteria find it harder to cling on and the gum can reattach more closely to the tooth. It is reserved for people who have developed gum disease, where pockets have formed between the gum and the tooth. Our guides to gum disease and bleeding gums explain how the disease develops.
Why pocket depth matters
Healthy gums sit snugly against the teeth with shallow spaces of around 1 to 3 millimetres. When gum disease takes hold, these pockets deepen as the supporting tissue is lost, and deeper pockets trap bacteria that brushing cannot reach. Your dentist measures these depths to decide if a deep clean is needed. The evidence shows scaling and root planing is effective at reducing pocket depth and improving gum attachment, with greater improvements in deeper pockets, though very deep pockets and back teeth can be harder to clean fully and sometimes need further treatment.

What to expect during treatment
The procedure is usually carried out with local anaesthetic so the area is numb and comfortable. Using hand instruments and an ultrasonic scaler, the dentist or hygienist cleans below the gumline, quadrant by quadrant, which is why treatment is often split across two or more appointments. Afterwards the gums may feel tender and the teeth a little sensitive for a few days, which settles. You will be given clear aftercare advice and a plan for follow up. The table below compares the two types of clean.
| Feature | Routine clean | Scaling and root planing |
|---|---|---|
| Purpose | Maintain healthy gums | Treat gum disease |
| Depth | Above the gumline | Below the gumline, onto the root |
| Anaesthetic | Not usually needed | Often used for comfort |
| Visits | Usually one | Often more than one |
What happens after a deep clean?
Healing happens over the following weeks as the gums tighten back against the teeth and inflammation settles. Your daily cleaning is what protects this result, so brushing well and cleaning between the teeth matter more than ever. Many people move onto a maintenance programme with more frequent cleans to keep the disease under control. Because gum disease is linked with general health, looking after your gums supports more than your mouth, as our guides to heart disease and gum disease explore.

Frequently asked questions
Is scaling and root planing painful?
It is usually done with local anaesthetic, so the procedure itself is comfortable. Some tenderness and sensitivity for a few days afterwards is normal.
How many visits will I need?
It is often split across two or more appointments, treating part of the mouth at a time, so each visit is more manageable.
Will my gums go back to normal?
The aim is to halt the disease and let the gums heal and reattach. Lost bone does not fully regrow, which is why early treatment and good maintenance matter.
Do I need it if my gums only bleed a little?
Bleeding can be an early warning sign. Whether you need a deep clean depends on your pocket depths, which your dentist measures. Mild gum inflammation may only need a regular clean and better home care.
How often will I need it?
After the initial treatment, many people move to a regular maintenance schedule. How often depends on how well the disease is controlled.
The takeaway
Scaling and root planing is the standard, evidence based first treatment for gum disease, cleaning below the gumline to reduce pocket depth and let the gums heal. Whether you need it comes down to your pocket depths, not just symptoms. With good aftercare and maintenance it can keep gum disease under control.
