i’m having a very complex situation,
im 24 years and i already lack 4 teeth in my mouth ,as they have been removed 11 years back due to crowded teeth.(2 canines from upper jaw and 2 molars from lower jaw)….& after that i had lovely straight teeth but recently the upper teeth have come forward. and i wanted to push them back. so my doctor says i should remove two of my molars from the upper jaw to gain space and push the front teeth back. (as i have already done with the expander also and still the teeth are not in the proper place)

but im too scared to remove molars because if i remove two molars now, i will be left with only 12 teeth in the uper jaw and im scared it will alter my facial structure and make my face look flat as people say.
so doctor, will it affect my facial shape and lips in a negative way like that?

is it ok to have 26 teeth? i mean can a human survive with 26 teeth?

and is it a good option to remove 2 molars?

please please answer my problems and help me to take a better decision about removing teeth. thank you very much.,
