A handheld sonic tooth cleaner with a fine stainless-steel tip. High-frequency vibration helps loosen surface plaque, tartar buildup and stains from coffee, wine and smoking along tooth surfaces and the gumline. It's a between-visit personal-care tool, not a replacement for brushing, flossing or professional cleanings.

Start gently with a light touch, and stop if it's uncomfortable. If you have sensitive teeth, gum problems, crowns, veneers, implants or braces, check with your dentist before use.

Charge fully first. Hold the tip at a shallow angle against the tooth surface, never pointed into the gums, and use light, sweeping strokes for about two minutes without pressing. Rinse, then brush as normal, and follow the included instructions.

It can help lift surface stains from coffee, tea, wine and smoking. Results vary, and it isn't a whitening treatment: it won't change the natural shade of your teeth.
