A modular dental system, methods for controlling a modular dental tool, a dental system, a control module, and a treatment unit. In one embodiment, the modular dental system includes a modular dental system including a control module and a battery module. The control module includes a first end, a second end, a control sub-system, and a charging sub-system. The control sub-system is configured to communicatively couple to an attachment, detect an attachment identifier associated with the attachment when the attachment is removably attached to the first end of the control module, and control the attachment based on the attachment identifier. The battery module is configured to removably attach to the second end of the control module.
