About six minutes later, the film a brush slides over has been shaken loose from the tiny pores in the plastic. Water is enough most weeks. On heavier weeks, add a cleaning tablet (\u003ca href=\"\/products\/retainer-cleaning-tablets\"\u003esold separately\u003c\/a\u003e) and watch it fizz.\u003c\/p\u003e\n\n\u003ch3\u003eWill yours fit?\u003c\/h3\u003e\n\n\u003cp\u003eThe basket is a circle about three inches across. One appliance at a time: a full or partial denture, or a single upper or lower retainer or night guard, lies flat. A two-piece sleep appliance, with connectors joining the arches, will not fit.\u003c\/p\u003e\n\n\u003ch3\u003eWhy brushing is not enough\u003c\/h3\u003e\n\n\u003cp\u003eDentures, retainers and night guards are porous. A brush works the surface, which is why an appliance can look clean and still smell — what causes the odor has settled into pores below the surface, where bristles cannot reach.\u003c\/p\u003e\n\n\u003cp\u003eUltrasonic cleaning works differently. A plate beneath the tank vibrates faster than you can hear, forming microscopic bubbles throughout the water. Each one collapses against whatever is sitting in the tank, and that collapse dislodges what is lodged there. The water goes everywhere, so the bubbles go with it. It is the same principle used on surgical instruments and jewelry.\u003c\/p\u003e\n\n\u003cp\u003eWe ran a well-used night guard through a plain-water cycle before writing this. The water came out cloudy — that is soft film and debris coming off. The hardened mineral deposits on the biting surfaces stayed exactly where they were. Water shifts the soft material; mineral buildup needs a cleaning tablet, and some of it will not come off at all.\u003c\/p\u003e\n\n\u003cp\u003eWater alone handles most weeks. A \u003ca href=\"\/products\/retainer-cleaning-tablets\"\u003ecleaning tablet\u003c\/a\u003e for the heavier ones. Never toothpaste, which is abrasive, and never hot water.\u003c\/p\u003e\n\n\u003cp\u003eThe lid holds a UV lamp on its own switch, with a five-minute cycle. Everything we tell you about cleaning on this page is about the ultrasonic, because that is the part we tested.\u003c\/p\u003e\n\n\u003ch3\u003eSound\u003c\/h3\u003e\n\n\u003cp\u003eThe ultrasonic frequency itself is above hearing, but the housing hums while it runs — a little louder than an electric toothbrush. You will know it is on. It stops on its own after a few minutes.\u003c\/p\u003e\n\n\u003ch3\u003eUsing it\u003c\/h3\u003e\n\n\u003cp\u003eAdd water to the fill line before plugging it in — running the unit dry is what damages these. Put the appliance in, close the lid, press power. It starts a countdown, and the clock button steps through 90, 180, 360 and 480 seconds. When it finishes, unplug it before lifting the appliance out, then empty the tank and dry it. Do not leave it running unattended.\u003c\/p\u003e\n\n\u003ch3\u003eWhat it will not do\u003c\/h3\u003e\n\n\u003cp\u003eIt will not whiten anything — staining that has soaked into the plastic is in the plastic. It will not remove hardened mineral buildup on its own. It will not repair a scratched appliance, because scratches hold debris and no amount of cleaning empties them. And it will not save an appliance that has reached the end of its life; one that has gone yellow and crusted at the back is a replacement conversation with your dentist, not a cleaning problem.\u003c\/p\u003e\n\n\u003ch3\u003eCommon questions\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes the UV lamp sterilize my appliance?\u003c\/strong\u003e\u003cbr\u003e\nWe do not make that claim. Sterilization has a specific clinical meaning — the elimination of all microbial life — and it is not a word we will use without evidence we can show you. The lamp is there and it runs a five-minute cycle. The cleaning we can speak to is the ultrasonic.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use it for anything else?\u003c\/strong\u003e\u003cbr\u003e\nYes. Rings, earrings, glasses, watch bracelets, toothbrush heads, coins. Anything that might fade, or that has loose stones, should stay out.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need the cleaning tablets?\u003c\/strong\u003e\u003cbr\u003e\nNot for ordinary weekly cleaning — water does that.
