Trauma to front teeth can be very traumatic mentally as well.
As you are young,
In my opinion,
If the teeth “4 th “ one , if can be saved. Do save it.
Three teeth , which you unfortunately lost , can be taken care of by replacement
1.Implants: i would advise to wait till you are 21 for implant placement
2.Maryland or fibre reinforced composite bridges are the options for fixed replacement
3.Removable partial denture is also viable option
Last two 2 & 3 can-be used during healing period of implant, if not being loaded immediately
Hope that helps
Good luck
