DOES CHEWING ON TENNIS BALLS WEAR TEETH?
Reportedly the tennis balls may wear down teeth, and washing the balls would solve the problem. I had hard time believing this theory at first based on my experience as a tennis player. Most of my experience with tennis balls comes from when I was playing lots of tennis and stringing tennis racquets. When playing tennis on a hard court, the felt on tennis balls tends to wear out after couple hours of playing. The hair on the balls comes so much shorter that you can actually notice a difference in the ball diameter when comparing to new balls. Also, during the play typically at least three balls are used, and they all wear down. This makes me think that tennis balls are not very abrasive. Also, the strings on a tennis racquet tend to wear down after about 10-100 hours of play depending on the players skills and spin used on the ball. Racquet strings mainly wear down because of the friction between crossing strings when they move relative to each other. I have not noticed really any wear
