A medical or a dental procedure?

Hi. Do we need to put theh indefinite article in front of both "medical" and dental" to distinguish what each of them are like "a white and a black T-shirt"? I think if it were "a medical or dental procedure," there would be be no need to put the indefinite article before the word "dental" (since it is contextually clear that it is meant one type of procedure each), but I am not sure when it is connected with the conjunction "and." Thank you for your help in advance.

What's your recent personal experience with a medical and dental procedure (a medical and a dental procedure)?
