@MaizyShiba approves but could use a couples mods to it.
It fits great between @MaizyShiba 's outer mouth and her teeth!<br /><br />It is durable and sturdy to withstand her love of chewing on it softly with her dental gel on it; however, the bristles need to be on both sides and remove a bit more buildup.<br /><br />I took away a star due to how the bristles part can spin around easily and thus has the option of coming off fairly easily.  It hasn't done so on my watch, but I see it as a possibility.<br /><br />Mods desired:<br />1.  All Around bristles that are tougher a bit for the teeth but still great for gums.<br />2.  For the bristles part to not spin easily and have the possibility of coming off.  Maybe make a one piece Silicon brush with a thin stainless steel rod in end part of the handle to keep the sturdiness level.
