Braces Vs Implant - I need braces and an implant, because I have a missing tooth. Confused of what to do first.

As a rule of thumb implants would come after the orthodontics.  However, sometimes an implant can assist in the ortho treatment, so the decision may be made for you by the dentist.

If braces are first, the teeth can be lined up for the right amount of space for the implant to be placed.  Once an implant is placed, it won't move.  Ever.  Teeth can move (braces) but implants won't.

Most of the times it is good to do the braces first and then the implants. Doing braces first would actually put the teeth and their roots in the right place and alignment and then the remaining space made can be restored with implants. Since implants are fused to the bone they WILL NOT move with braces whereas natural teeth will. In some cases, teeth behind the space can be pulled forward and make it unnecessary for the implants to be placed.It would be great if you can see the orthodontist first before making any decisions. Hope you find this helpful.

In most cases, it is best to do orthodontics prior to placing implants or any other major dental restoration.  If you think about it, we need to put the existing teeth in the right places so that any new replacement teeth will fit the new bite.  If you put an implant in and then try to move all teeth, it might be in the way and/or not even fit with the new bite.  Occasionally we will use implants or even temporary implants for "anchorage", but unless your orthodontist says they need that, it is best to wait until after or at least near the end of the braces to begin the implant process.

Good luck!
