Well, it seems that Wall-E is inadequate in his new role; in this case size does matter. His childlike bristles do not meet the needs of my adult sized teeth.
So what to do? All of the grown-up toothbrushes are sleek and smooth. I pondered and pondered (for all of 15 seconds) when it came to me: blue foam tubing. Just as with my car key and my silverware, blue foam tubing would solve the problem.
Dear Jenny cut two lengths of tubing and cut along the length of each; she then placed each piece on either side of the Crest toothbrush, securing them top and bottom with elastics.
Once again, I present to you the product of my creative (if warped) imagination:
Sometimes I amaze myself.
(Looks to me like it's time to buy new bristles.)
