In case of extraction of both Maxillary and Mandibular teeth in a Full mouth rehabilitation case we need to follow a sequence or step by step procedure to extract all the teeth.
It is also called as “Full Mouth Extraction”
Maxillary teeth are extracted first which is a rule we always follow and also the rule that posterior teeth are extracted before extracting anterior teeth.
Both of these rules are followed even in full mouth extraction in both maxillary and mandibular teeth.
Sequence of teeth to be extracted in full mouth extraction:
- Maxillary posterior teeth (1st and 2nd Premolars, 2nd and 3rd molars) except 1st molars
- Maxillary anterior teeth(centrals and laterals) except canine
- Maxillary 1st Molar
- Maxillary Canine
- Mandibular posterior teeth (1st and 2nd Premolars, 2nd and 3rd molars) except 1st molars
- Mandibular anterior teeth(centrals and laterals) except canine
- Mandibular 1st Molar
- Mandibular Canine

The 1st molar and canine are extracted last in each quadrant because they help in maintaining the stability and integrity of the alveolar mucosa of the quadrant anteriorly by canine and posteriorly by 1st molar.
We have to first suture the Alveolar mucosa posterior to the 1st molar and alveolar mucosa anterior to the Canine in the quadrant.
