Wrong Tooth Extracted

[HFILE]

good day. i became a member of different forums just to seek help coz idont want to make a bad decision again.

my case. my dentist extracted no.4 tooth upper&lower. the upper spaces is ok now-closed but horrible problem is the lower- huge spaces.
my NEW dentist told me my bite is better now and these are my options for the spaces
1. flexible/dentures
2.bridge crown

is it necessary to have rootcanal for crown placement? (some dentist i asked says so)

iwant to closed the spaces(by braces) crowns are expensive but its not advisable bcoz iwill again have a deeper bite or my lower will again move inward.
please enlighten me.
attached files for references
waiting. TIA
thnks for this forum

Your orthodontic treatment is not finished. Did you have to move and that’s why you have a new dentist? Have you sought the opinion of an orthodontist? How long have you been I. Treatment? What did you look like before?
