i am not sure if this is the place to post this but here we go. what is the best way to shave someone who has no teeth. everything was going along smoothly until the upper and lower lip area. there is nothing to push back on when youre trying to shave those areas. the beard was very long and had to be trimmed down which i am sure doesnt help any. i did nick his lower lip but luckily he didnt complain to much. he is wanting to get shaved once a week or so which i am hoping will help but any advice or information pertaining to this would be much appreciated.
