I have always had a problem with gritting and clenching my teeth.  I am 67 and go without denture when home alone.  The past few weeks I am wearing myself out clenching.  I take 20 mg Lexapro for depression.  Just increased it last week from 10 to 20.    I have already chipped the front tooth on my denture.   I have been steadly gaining weight recently and am 75 pounds heavier than normal.
Hi. Thanks for the query. As per your complaint as you already have a history of depression, therefore your clenching habit seems to be related to anxiety and stress. So in case if you are wearing your teeth n your dentures then you need to consult your dentist and get evaluated, and he can fabricate mouth guards for you to help you with the problem.Also, you should check with your Physician and get evaluated so that he can advise you appropriate doses of anti depressants to ease with the situation. Also doing meditation and deep breathing exercises can help you. For weight gain it can be due to hormonal problems like Hypothyroidism or overeating caused due to stress and anxiety. So get a proper examination done and once the cause is ruled out it can be treated accordingly. Hope this information helps. Regards.
