The body includes an extension and at least a portion of a side of the extension is configured to be covered by the stem when the toothbrush head is coupled with the body. The appliance brush is configured to couple to the extension when the toothbrush head is not coupled with the body.

A method includes sending a dental impression kit to a patient including dental trays of different sizes. The method includes receiving one or more dental impressions created using one or more dental trays having been selected by the patient from the plurality of dental trays, providing treatment plan data and a size indication to a provider computing device, receiving a communication approving the treatment plan, and manufacturing a plurality of dental aligners specific to the patient and being configured to reposition one or more teeth of the patient.
