 [ Symptoms ] i am on a doctor prescribed liquid diet and am chewing gum between meals should i brush after every meal instead [ Disease ] there are two issues here let is start with the brushing first i love the fact that you want to brush after every meal this is the best way to keep excellent oral hygiene however if you cannot brush after every meal brushing morning and night is quite sufficient the best thing is to ask your dentisthygienist to evaluate your home care and let himher give you the proper feedback if you are doing it right the gum issue is different gum chewing on the contrary to the trident commercial is not totally good for you the good thing is that it stimulates salivation making your mouth ready for food consumption is that what your really want when you are on a diet  the bad thing about gum chewing is that it over exercises your muscles of mastication we are not supposed to chew non stop throughout the day when you do that you are putting undue stress on your teeth and muscles and cause premature wear and tear your teeth should only come into contact when you swallow and if they do otherwise you will experience premature wear of your dentition keep brushing and flossing regularly and easy on the gum chewing
