Does chewing on a pacifier harm my teeth?

Not likely, but risk: It is very unlikely that chewing on a pacifier will hurt the teeth, however, it is a big risk for choking. Chewed pacifiers can have small pieces that fall off and a child can have life-threatening choking, so it is good to discourage this behavior and also frequently check pacifiers to make sure no tears or holes have occurred.

Your Teeth?: The answers depends on what you are asking. Are you asking about your teeth, or a child's teeth? Most likely there will be no damage done to your teeth by chewing on a pacifier. For a child there can be damage to the way the jaw grows and future orthodontic issues.
