The toothbrush comprises a front ring having two frontwardly extending front members connected by a front brush head member and a number of bristles which extend upwardly from the front brush head member. it also has a rear ring and a centre bar which extends between the front ring and the rear ring. There is a front opening is defined between the front ring and the centre bar, and the front opening is large enough to receive at least two human fingers through it. A rear opening is defined between the rear ring and the centre bar, and the rear opening is large enough to receive at least two human fingers through it. The centre bar defines an angle with one of the front members of less than 90 degrees, and defines an angle with the other of the two front members which is greater than 90 degrees, to thereby define a wedge space, into which the fingers of a user may be inserted and wedged to thereby retain control of the toothbrush. |
