5 . The toothbrush of claim 4 , wherein the neck is directly connected to the rear one of the two distinct longitudinal portions and separates the rear one of the two distinct longitudinal portions from the forward grip portion and the rear grip portion.

6 . The toothbrush of claim 1 , wherein each of the forward grip portion and the rear grip portion is asymmetric relative to a primary axis of the rear one of the two distinct longitudinal portions.

7 . The toothbrush of claim 1 , wherein the at least two grip portions approximate an offset V-shape or an offset U-shape.

8 . The toothbrush of claim 1 , wherein, with the toothbrush in a use position, the forward grip portion and the rear grip portion are each positioned on the one side of the rear one of the two distinct longitudinal portions such that the hand of the provider is entirely on the one side of the rear one of the two distinct longitudinal portions.

9 . The toothbrush of claim 1 , wherein the forward grip portion is spaced from the rear grip portion to enable one hand of the other person to grip the forward grip portion and one hand of the provider to grip the rear grip portion.

10 . The toothbrush of claim 9 , wherein the spacing between the forward grip portion and the rear grip portion is sufficient to accommodate the other person holding the forward grip portion while the provider holds the rear grip portion.

11 . The toothbrush of claim 1 , wherein the forward grip portion and the rear grip portion are spaced apart by a distance sufficient to enable a distinct hand to grip each of the forward grip portion and the rear grip portion simultaneously.

12 . A method of brushing the teeth of another person, performed by a provider, the method comprising:

at least partially inserting a toothbrush into the mouth of the other person,

with the toothbrush in the mouth of the other person:

a) contacting an inside of at least one upper tooth and concurrently contacting an outside of at least one lower tooth, and

b) contacting an inside of at least one lower tooth and concurrently contacting an outside of at least one upper tooth,

wherein (a) and (b) are performed without removing the toothbrush from the mouth of the other person, and

wherein the toothbrush includes:

a head including an approximately dumbbell-shaped core and a set of brushing portions extending from the approximately dumbbell-shaped core, the set of brushing portions including an upper brushing portion and a lower brushing portion, wherein the upper brushing portion and the lower brushing portion are oriented and spaced apart relative to one another to enable a user of the toothbrush to brush upper teeth and lower teeth of another person without removing the toothbrush from the mouth of the other person, and

a handle coupled with the head, the handle including:

at least one longitudinal portion positioned relative to the head such that a hand of the provider is oriented at a distinct angle from the head while brushing the teeth of the other person and holding the at least one longitudinal portion,

wherein the at least one longitudinal portion of the handle is positioned relative to the head to enable the hand of the provider to remain in a handshake position while brushing the teeth of the other person, and

at least two distinct grip portions extending from the at least one longitudinal portion, the at least two distinct grip portions including a forward grip portion and a rear grip portion, the forward grip portion being longer than the rear grip portion,

wherein the handle further includes an offset from the head allowing the user to view the mouth of the other person while brushing the upper teeth and the lower teeth,

wherein the rear one of the two distinct longitudinal portions includes a neck from which each of the two distinct grip portions extends,

wherein each of the forward grip portion and the rear grip portion includes a proximal portion coupled with the neck and a distal portion opposite the proximal portion, and wherein a distance between the distal end of the forward grip portion and the distal end of the rear grip portion is greater than a width of the neck,

wherein each of the forward grip portion and the rear grip portion is asymmetric relative to a primary axis of the rear one of the two distinct longitudinal portions,

wherein, with the toothbrush in a use position, the forward grip portion and the rear grip portion are positioned on the one side of the rear one of the two distinct longitudinal portions such that the hand of the provider is entirely on the one side of the rear one of the two distinct longitudinal portions, and
