Cleaning Bonded Retainers
It is not possible to use dental floss with bonded retainers but as the front teeth are relatively narrow it should be possible to clean between the teeth with the bristles of your toothbrush. It is particularly important to do this around the gum margins.
Recent studies show no deterioration in the health of the teeth or gums after bonded retainers are left in place for 20 years provided that the area is brushed adequately.
Many people have a tendency to build up calculus deposits behind their lower front teeth and these people will need a professional cleaning with their dentist every 6 months whether they have bonded retainers or not.
