Description: Your Sonicare is safe to use on: braces (brush heads wear out sooner when used on braces),dental restorations (fillings,crowns,veneers) and periodontal pockets. Two-minute timer automatically tracks brushing time and turns the toothbrush off after two full minutes of brushing is complete. Uniquely angled brush head neck makes it easier to reach back teeth,removing plaque in those hard-to-reach areas.
