People who have undergone orthodontic treatment know that to maintain the aesthetics and alignment of the teeth, as well as the bite, it is necessary to know the types of dental retainers and use a retainer to give continuity to the treatment .
After orthodontic treatment, the teeth may be a little loose and the gums sensitive, making it possible for them to move and return to the position they were in.
Fixed retainer
Also called permanent retainers, these are fixed by means of a wire to the teeth. They are commonly used on the lower teeth as an option for those who forget to wear their retainer at risk of relapse (such as children).
