A computer-implemented recommendation system is for recommending a type of oral care accessory to be used with an oral care device. The recommendation takes account of oral geometry information in respect of a user and preferably also user behavioral information in respect of the manner in which the particular user conducts their oral care using the oral care device. The recommendation is based on the modelling of mechanical interactions between one or more oral care accessories of a set of oral care accessories and the oral geometry of the user when the user performs an oral care routine. From said modelling a cleaning metric is determined that represents the effectiveness of the oral care routine when using said one or more oral care accessories.
