Yes! Smilelume uses UV-C light at a wavelength of 253.7 nm, which is scientifically proven to kill up to 99.9% of bacteria and viruses by breaking down their DNA and stopping them from reproducing. In lab tests, Smilelume has been shown to effectively eliminate harmful microorganisms commonly found on toothbrushes, such as E. coli and Staphylococcus aureus. This ensures your toothbrush is sanitized and safe to use every time.

Yes, Smilelume is designed with safety in mind. While UV-C light can be harmful to skin and eyes with direct exposure, Smilelume ensures that the UV light is fully contained within the device during operation. This means you are never exposed to the light while it’s sanitizing your toothbrush. Always follow the user instructions for safe and proper use.

For the best results, we recommend using your Smilelume UV light after every brushing to keep your toothbrush clean and fresh. Daily use is ideal, especially if you brush twice a day. If you've been sick, it's a good idea to sanitize your toothbrush after each use to prevent reinfection. If your toothbrush is in a shared space, consider using the UV light more often to reduce exposure to germs. At a minimum, aim to clean your toothbrush 2–3 times a week.

The UV light in Smilelume typically lasts for 6 to 12 months or around 1,000 to 1,500 uses. We recommend replacing the UV light bulb when you notice a decrease in performance or after 12 months.

While replacing your toothbrush regularly is important, a SmileLume UV light adds extra protection by sanitizing your toothbrush after each use. Even new toothbrushes can carry germs from your mouth and the bathroom. Using a UV light helps keep your toothbrush free from bacteria between replacements, improving your oral hygiene. It’s a quick, effective, and chemical-free way to keep your toothbrush cleaner for longer.

Yes! Even if you clean your toothbrush regularly, Smilelume UV light gives it an extra level of cleanliness. Regular cleaning might remove visible dirt, but UV light helps kill germs and bacteria that can be missed. It’s an easy, chemical-free way to keep your toothbrush extra hygienic.
