i had upper and lower jaw surgery so i had alot of numbness in my chin afterwards the part that bothered me the most was that i would have something drippind down my chin and i couldnt feel it. but the numbness didnt go away completly for a good 6 months it was rather unfortunate. but advice for you would be buy her a vaporizer because i was miserable because i could not breath outa my nose hardly because upper jaw surgery makes you have a stuffy nose and when your mouth is wired shut and your nose is plugged up its NO FUN trust me. so vaporizers helped me alot. also tomato soup is great i lived off it for 2 weeks
