I have this dental appointment for a deep cleaning that I really need to go to. My dentist has been telling me I should have this done but I have been putting him off. I finally make a appointment to have a deep cleaning for tomorrow and now I am really sick. I am not sick because I have the appointment I just have the flu, it all just bad timing. I was just wondering if I should still keep my dental appointment. Would it be okay? I am concerned that the dentist will think I am making it up, but if I go sick will he be upset with me? Not sure what to do.
