If I say the lower part of an upper tooth do you think I mean the part near the gum or the end of the tooth?

I had a miscommunication with my dentist, and I am just so sick and tired of miscommunicating with healthcare professionals. I swear it is going to give me a nervous breakdown. I want to know what others assume if I said the lower part of my front upper tooth. She knew the tooth we were working on so all I said was, “I think it still needs to be filed more lower down on the tooth.” I had the tooth repaired and my bite was off, so she was filing it to try and help my problem.
