“I had scaling, so why do my gums keep bleeding?”
Some patients receive scaling for bleeding or sensitive gums, only to notice swelling and bleeding again a few days later. When recurrent periodontal pockets are left unmanaged, the supporting bone can gradually deteriorate. Teeth that were otherwise healthy may loosen and eventually require extraction. The key principle of periodontal treatment is therefore simple: to preserve natural teeth, treatment must go beyond routine scaling and address the cycle of recurrence.
At Hana Dental Clinic in Changwon, Dr. Hosan Park—an American Board of Periodontology–certified periodontist—uses a sequence of four treatment steps for selected recurrent or difficult periodontal pockets. We call this the 4S Gum Care Protocol.
Scale — SRP, the essential first step
Scaling and root planing (SRP) mechanically remove calculus and bacterial biofilm from the tooth and root surfaces. It is the standard foundation of periodontal treatment and the starting point of the 4S protocol. If debridement is incomplete, the benefit of any additional therapy is limited. At Hana Dental Clinic, thorough mechanical cleaning always comes before the next step.
Sterilize — K2 diode laser treatment for areas instruments may not reach
Deep, narrow periodontal pockets can include areas that are difficult to reach mechanically with SRP alone. The K2 wireless dental diode laser is used as an adjunct in these selected sites to reduce bacteria and remove inflamed granulation tissue.
Suppress — Minocline for sustained local bacterial control
After initial laser disinfection, bacteria that may remain within the periodontal pocket can require continued suppression. Minocline is a locally delivered, sustained-release formulation of 2% minocycline hydrochloride. It is placed directly into the pocket and maintains an effective local antibacterial concentration for more than one week.
Soothe — Selbein injection (PDRN) to help calm inflammation
Once bacterial reduction and suppression have been addressed, the final step focuses on calming the inflammatory response in irritated periodontal tissue. PDRN (polydeoxyribonucleotide) is understood to activate adenosine A2A receptors, suppressing pro-inflammatory mediators while promoting anti-inflammatory activity.
Untreated periodontitis can destroy the supporting bone and eventually lead to tooth loss. The 4S Gum Care Protocol applies Hana Dental Clinic’s philosophy—saving rather than extracting—to periodontal care. Its goal is to reduce bacteria through Scale, Sterilize and Suppress, then support tissue recovery through Soothe, helping patients retain their natural teeth for as long as possible.
Why use these steps in this order?
Each part of 4S addresses a different problem in sequence.
- Scale — mechanically remove calculus and bacterial biofilm
- Sterilize — disinfect areas that instruments may not fully reach and remove inflamed tissue
- Suppress — maintain local antibacterial activity after initial disinfection
- Soothe — calm the inflammatory response and support recovery of irritated tissue
This clean–disinfect–suppress–soothe sequence reflects a basic principle of periodontal care: reducing bacteria and calming inflammation are related, but distinct, treatment goals. Both serve the larger goal of preserving natural teeth.
Frequently asked questions
No. Mild gingivitis and early periodontitis can often be managed with scaling and effective daily oral hygiene. The 4S approach is considered mainly for selected cases that recur after scaling or for deeper periodontal pockets that improve slowly with SRP alone.
No. The necessary steps depend on pocket depth, the degree of inflammation and whether the condition has recurred. After a detailed examination, the dentist recommends only the steps appropriate for the individual patient.
These procedures can often be performed without local anesthesia and generally do not add major discomfort or recovery time compared with conventional scaling. Temporary sensitivity can occur depending on the condition of the gums.
Selbein is a PDRN-based dental injectable approved in Korea. As with any medical procedure, outcomes and reactions vary according to the patient’s health and individual characteristics. A careful consultation with the treating dentist is essential.
No treatment can guarantee that outcome. Periodontal disease is usually managed rather than permanently cured, and results depend on the initial condition and ongoing care. Regular examinations and supportive periodontal therapy (SPT) remain important after active treatment.
