Three registers for one act
- extraction and tooth removal — clinical, and what goes in the notes
- have a tooth out — the British conversational norm: I had a tooth out yesterday
- get a tooth pulled — the American one: I got my wisdom tooth pulled
Note that serial extraction is not a series of extractions in general: it is the planned removal of primary teeth for orthodontic reasons.
The division that matters is difficulty:
- simple extraction — forceps only, no incision
- surgical extraction — incision, flap, bone removal or sectioning the tooth
This is a category, not a description: it drives time, consent and cost. Coronectomy is the deliberate retention of the root when removing it would risk the nerve.
Eight ways to describe an unerupted tooth
Impaction is classified on two axes. By angulation:
- mesioangular impaction — tilted forward, the commonest
- distoangular impaction — tilted back, technically the hardest
- horizontal and vertical impaction
By depth and tissue cover:
- soft tissue impaction — under mucosa only
- partial impaction and full bony impaction
Nearby: a retained root left from an earlier extraction, and an ankylosed tooth fused to bone.
The surgical sequence
- flap design and incision
- flap elevation — raising the mucoperiosteal flap
- bone removal / ostectomy
- tooth sectioning — dividing the tooth
- luxation — loosening it
- socket curettage and socket irrigation
- wound closure — suture, resorbable or non-resorbable, then suture removal
The space left is the socket or alveolus. Healing runs blood clot → granulation tissue → bone remodelling, with primary closure or secondary healing. If an implant is planned, socket preservation or ridge preservation is done at the same visit.
Dry socket and the other complications
- dry socket is the everyday clinical name; formally alveolar osteitis — the clot breaks down and the socket becomes painful around day three to five
- post-extraction bleeding and excessive bleeding
- wound dehiscence — the wound opening up
- tuberosity fracture — fracture of the maxillary tuberosity
- oroantral communication and sinus perforation
- nerve damage, inferior alveolar nerve injury, lingual nerve injury, altered sensation
- displaced root — a root pushed into the tissues
- post-operative infection, swelling and pain
Aftercare vocabulary: gauze pack, pressure pack, ice pack, soft diet, post-operative instructions.
Usage notes in this chapter
- Extract is the verb in writing; take out and pull are what is said aloud, and pull is normal rather than harsh in American English
- Socket and alveolus are interchangeable, but socket dominates in speech and alveolus in anatomy
- Luxation here means loosening the tooth deliberately; in trauma it means an injury — same word, opposite intent
- Dry socket contains no dryness worth imagining — the name refers to the empty, clotless socket
- Impacted means blocked from erupting, not jammed or crowded
- Dehiscence is pronounced /dɪˈhɪsəns/ and appears far more in writing than in speech
