1. A computer readable medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:
receiving a first one or more intraoral scans of a patient's oral cavity;
determining that the first one or more intraoral scans depict a first dental arch of a patient;
determining a first three-dimensional surface of the first dental arch using the first one or more intraoral scans; and
determining that the first dental arch of the patient is a lower dental arch rather than an upper dental arch responsive to determining that at least one of the first three-dimensional surface or some of the first one or more intraoral scans include a representation of a tongue, wherein for at least one of the first three-dimensional surface or an intraoral scan of the first one or more intraoral scans the lower dental arch is detected if at least a threshold number of points in the first three-dimensional surface or the intraoral scan depict the tongue.
