Does scaling and root planing hurt?
Scaling and root planing — often called a "deep clean" — is the non-surgical treatment for gum disease, and it is done under local anaesthetic. The area being treated is numbed first, so during the procedure itself most patients feel pressure and vibration rather than pain. Scaling and root planing is the cornerstone of non-surgical periodontal therapy: the careful removal of plaque and hardened deposits (calculus) from the tooth surfaces below the gum line, where a toothbrush cannot reach (American Academy of Periodontology).
Because the roots are cleaned beneath the gum, the work goes deeper than a routine "scale and polish". That is precisely why it is numbed. If any part of the area starts to feel sensitive while we work, we simply add more anaesthetic — there is no need to push through discomfort.
How is the treatment carried out?
Scaling and root planing is usually completed over one to two visits, and frequently the mouth is treated one section — one quadrant — at a time. Treating by quadrant lets a single area be fully numbed and thoroughly cleaned in a focused sitting, which most patients find more comfortable than trying to do everything at once.
Internationally, subgingival instrumentation of this kind is the recommended first step of treatment for early-to-moderate gum disease, before any decision about surgery (EFP S3 clinical practice guideline, 2020). The aim is to reduce the depth of the gum pockets and stop the inflammation, so the gum can reattach more closely to the tooth.
What does recovery feel like afterwards?
Once the anaesthetic wears off, it is normal for the treated gums to feel tender or sore for a few days, and for the teeth to be sensitive to cold for a short while. This happens because cleaning below the gum line removes deposits from the root surface and allows the inflamed gum to begin tightening back against the tooth. For most people the soreness is mild and short-lived.
A few simple measures make the first few days easier:
- Simple pain relief. Over-the-counter analgesia such as paracetamol is usually enough; take it as directed on the packet.
- A soft diet, briefly. Favour softer foods for a day or two and avoid very hot, very cold, or very crunchy items while the area settles.
- Gentle, continued brushing. Keep cleaning the area — gently — rather than avoiding it. Plaque control is what allows the gum to heal; a desensitising toothpaste can help with cold sensitivity.
- Expect a little bleeding. Light bleeding when you brush the treated area for the first day or two is common and improves as the inflammation resolves.
Across the published trials, subgingival instrumentation is generally well tolerated and reliably reduces pocket depth and bleeding when followed by good home care (Suvan et al., systematic review, 2020). Serious problems are uncommon, but you should contact the practice if you develop increasing pain after the first few days, swelling, or a fever, as these are not part of normal healing.
What happens after the deep clean?
We arrange a re-evaluation appointment about six to eight weeks later. At that visit we re-measure the gum pockets and bleeding to see how the tissues have responded. Most sites improve and then move into a regular maintenance programme. Some deeper or more stubborn pockets may not fully resolve with non-surgical treatment alone, and a small number of sites may need a surgical procedure to clean or reshape them — this is a normal part of staged periodontal care, not a sign that the deep clean failed.
Common questions
Will I be in pain during the procedure? No — the area is numbed with local anaesthetic first, so the treatment itself causes little or no pain. You may feel pressure and vibration. If anything becomes sensitive, more anaesthetic is given.
How long does the soreness last afterwards? Usually a few days. Gums may feel tender and teeth sensitive to cold for that time, then settle. Simple pain relief, a brief soft diet, and gentle brushing are normally all that is needed.
How many visits does it take? Most patients are treated over one to two visits, often by quadrant. The number depends on how many areas are affected and how deep the pockets are.
Will I need gum surgery as well? Often not. Scaling and root planing resolves many sites on its own. Deeper pockets that do not respond at the six-to-eight-week review may need a surgical step, which is decided only after seeing how you heal.
