i always seem to chew on plastic water bottle caps and lollipop sticks. they say not to do it but me being me i don't listen but i wanna no!
No it is not safe to chew on plastic. It is not considered good because of two reasons 1. Chewing on plastic will break some molecules of the plastic which you are bound to ingest and cause health problems to the extent of cancer or tumors. 2. You will injure your gums and teeth by chewing on plastic. So DO NOT DO IT!!!
