Abstract
A brushing mouthpiece device for insertion into a subject's mouth and cleaning an oral surface during use with at least one group of first and second cleaning elements respectively, wherein the second cleaning elements are stiffer than the first cleaning elements and adapted to contact a tooth during use so that the force generated by the stiff second cleaning elements pushing against a tooth urges the mouthpiece to a target alignment position relative to the subject's teeth, whilst still cleaning.
Claims15
A mouthpiece device for insertion into a subject's mouth and cleaning an oral surface during use, comprising:
- at least one group of first cleaning elements projecting from a surface of the mouthpiece device, the at least one group of first cleaning elements having a first stiffness value, and wherein the at least one group of first cleaning elements is adapted to clean an oral surface during use;
- and
- at least one group of second cleaning elements projecting from a surface of the mouthpiece device, the at least one group of second cleaning elements having a second stiffness value which is higher than the first stiffness value, wherein the at least one group of second cleaning elements is adapted to contact at least one tooth surface of the subject during use to urge the mouthpiece to a target alignment position relative to the subject's teeth,
- and wherein the at least one group of second cleaning elements are adapted to contact the central developmental groove of the occlusal plane of the subject.
