A dental tray liner including a sheet configured to cover the bottom of a conventional dental tray. On the upper surface of the sheet is imprinted a chart of the teeth found in the human mouth with representations of the upper teeth arranged in a row adjacent similar representations of the lower teeth. During a dental examination, a user may easily note applicable dental conditions on the chart with a writing implement. After the examination, the user may, without touching the patient or liner, transcribe the information noted on the chart into a patient's permanent record without danger of spreading germs.
