I have a bridge for 4 upper front teeth I feel they are slightly protruded. I want braces to improve the appearance? (Photos)

I broke a part of my upper front teeth in my childhood. 4 yrs ago RCT was done and crown was placed on that teeth. later an infection began and it spread to 2 adjacent teeth, RCT was done to them & bridge was inserted to 4 front upper teeth.Though the bridge is doing fine it is slightly protruded so i want to have braces, to slightly move them back for aesthetic reasons. My question is that can braces be placed on the bridge of 4 upper front teeth? which kind of brace is suitable for bridge?
