Food particles and other bacteria get accumulated in and around the wires and brackets of the whole braces assembly. There is more plaque and tartar buildup around the brackets as compared to when there are no braces. Regular tooth brushing techniques with a regular toothbrush do not suffice as the toothbrush bristles do not reach very small areas. As a result, poor oral hygiene during this time can cause bad breath, gum infections and make your teeth more prone to decay.
