Simple versus surgical extraction consent
A simple extraction removes a visible tooth using forceps and elevators, while a surgical extraction involves cutting gum tissue or removing bone to access a tooth that is impacted or broken below the gumline. The risk profile differs enough that a tooth extraction consent form should specify which type applies.
- Simple extraction: typically local anaesthetic only, shorter recovery, lower complication rate
- Surgical extraction: may involve incision, bone removal or tooth sectioning, longer recovery, higher risk of swelling and nerve involvement
Risks that belong on an extraction consent form
Every extraction consent form should name the common and less common risks separately, so a patient can weigh genuine likelihood rather than treating all risks as equally probable.
- Pain, swelling and bruising in the days following extraction
- Dry socket, a painful condition where the healing blood clot is lost prematurely
- Infection requiring antibiotics or further treatment
- Nerve injury causing temporary or, rarely, permanent numbness of the lip, chin or tongue
- Damage to adjacent teeth, fillings or crowns during the procedure
- Sinus involvement for upper back teeth extractions
Nerve injury risk in lower wisdom tooth and molar extraction
Lower wisdom teeth and lower molars sit close to the inferior alveolar and lingual nerves, and extraction in this area carries a recognised risk of altered sensation. This risk should be disclosed specifically, matching the standard expected for oral surgery generally.
Where imaging shows a tooth root is close to the nerve canal, this should be discussed directly with the patient before they decide whether to proceed.
Tooth replacement options and alternatives to extraction
Before agreeing to extraction, a patient should be told whether root canal treatment could save the tooth instead, and what replacing an extracted tooth would involve if they choose removal.
A gap left by extraction can shift neighbouring teeth over time, so replacement options such as a bridge, implant or partial denture should be mentioned even if the patient decides not to pursue one immediately.
Aftercare instructions and reducing complication risk
Written aftercare instructions reduce the chance of dry socket and infection, and should be given alongside verbal advice at the time of extraction. Instructions typically cover avoiding smoking, drinking through a straw, and vigorous rinsing for the first 24 hours.
Patients should be told which symptoms are normal and which warrant a return visit, particularly worsening pain a few days after extraction, which often signals dry socket rather than typical post-operative discomfort.
United States
State dental boards require documented informed consent for extractions, and many states specifically expect disclosure of nerve injury risk for lower molar and wisdom tooth procedures.
United Kingdom
GDC standards require dentists to discuss alternatives, including root canal treatment, before extraction, and to name nerve injury risk where clinically relevant.
Canada
Provincial dental regulatory colleges expect written consent for extractions, with patient records and consent documentation governed by PIPEDA.
Australia
The Dental Board of Australia's guidelines require that patients understand the risks of extraction, including nerve injury, before treatment proceeds.
