Review (5/5): It fits!
I tried some of the other brands or infant finger toothbrushes and when I used them, they fit so tight that I could barely feel my finger. The Nuk Infant Finger Toothbrush & Massager is more flexible and doesn't cut off my circulation. I am 6'1" and 195 with decent sized man hands. I'm also a dentist and I would recommend this product. I use it for my 15 year old handicapped daughter who has Rett Syndrome. She accumulates a lot of plaque and staining on the front of her front teeth. I use a regular toothbrush for her back teeth and the inside of her front teeth. I would recommend this for use ONLY in the areas where you cannot be bit!
