Post-Surgical Oral Hygiene Protocols

Practical guidance for managing oral hygiene in the days following an extraction or implant surgery: when to resume brushing, how to use chlorhexidine correctly, and for how long.

In the first 24 hours following oral surgery — extraction, implant placement, periodontal surgery — direct mechanical hygiene on the operated area should always be avoided: vigorous rinsing, brushing the surgical site and using a water flosser risk disturbing the clot or sutures, compromising initial healing. The rest of the mouth, unaffected by the procedure, can instead be treated with the normal home hygiene routine, including an electric toothbrush if already in use.

From the following day, the cornerstone of the post-operative protocol becomes chlorhexidine mouthwash, generally at 0.2% concentration, used undiluted and held in the mouth for a full minute, twice a day, for a period that in most protocols extends from 7 to 10 days. Chlorhexidine remains, to this day, the only agent able to effectively control oral bacterial plaque during the phase when normal mechanical hygiene is temporarily limited or entirely suspended on the treated area — which is why clinical protocols consider it irreplaceable at this stage, despite a well-known and reversible side effect: after about a week of continued use, brownish staining may appear on teeth and tongue, which disappears once treatment is discontinued.

Around the specific surgical site, the most common guidance is to suspend toothbrush use — especially electric, due to greater mechanical aggressiveness — until suture removal or explicit instruction from the surgeon, relying in the meantime solely on chlorhexidine rinses for plaque control in that area. Ice applied externally in the first hours (typically in 20-minutes-on, 20-minutes-off cycles, or as specifically instructed) helps contain swelling, which normally peaks between 48 and 72 hours before progressively subsiding.

It's important for the patient to understand the difference between a normal course and a warning sign: swelling, mild bruising and discomfort in the first 2-3 days are normal for most procedures, while worsening symptoms after the third day, fever, persistent bleeding or foul-smelling discharge should always be promptly reported to the practice, without waiting for the already-scheduled follow-up appointment.

On Oralzon you'll find chlorhexidine mouthwashes at various concentrations, ultra-soft post-surgical toothbrushes and hygiene kits dedicated to the post-operative course to recommend to your patients.
