No, there's no need to worry. The device springs to life once the metal cleaning head touches a solid surface. This unleashes real ultrasonic technology, causing vibrations at a frequency of up to 42KHz (equivalent to a mind-boggling 42,000 vibrations per second), too fast for the human eye to catch.

Not at all. This device is equipped with intelligent safety measures. It only activates its vibrations when in contact with your teeth or any hard surface. The moment it brushes against soft tissue like your gums or tongue, the vibrations halt automatically. Using it properly shouldn't cause you any discomfort. However, extended use on a high setting could lead to temporary tooth sensitivity for a day or two.

A fully charged device should vibrate at a frequency of 42KHz in high mode, a strength that's more than sufficient to remove various dental deposits. If you're experiencing weaker vibrations, consider two possibilities: 1. The metal cleaning head might need a firm tightening using the small spanner provided, or 2. The battery might be running low and could use some charging.

A minor temperature increase during operation is normal. However, if the cleaning head heats up excessively or you're hearing anything beyond the high-pitched tone, it's time to raise an eyebrow. Ensure you're using the original cleaning head and that it's securely tightened with the small spanner.

This plaque remover likes to stay efficient. Hence, it's designed to take a breather every 10 minutes with an automatic shutdown. No worries though, you can restart it and pick up where you left off. If the battery charge indicator is blinking or the device's shutting off right after powering up, it's giving you a low-battery nudge.

Keeping things hygienic is a breeze. Simply wipe down the cleaning head with some medical alcohol or give it a quick dip in boiling water for about 5 minutes. Just ensure it's dry before the next round of action.

Absolutely normal! It's akin to the mild gum bleeding that can occur when you're brushing your teeth vigorously. For a smooth start, opt for the soft cleaning mode. Typically, these sensations fade within a day or two after you stop using the device. If things don't improve after a week, don't hesitate to consult a dentist. Individuals with periodontitis, gingivitis, and other dental or gum conditions should avoid using this product. And if uncertainty looms, a quick chat with your dentist before using is a wise move.

A genuine ultrasonic plaque remover boasts a high-frequency ultrasonic transducer that conjures vibrations. When you activate the device and hold it, you won't feel these vibrations in your hand. The magic only happens when it meets a solid surface. In contrast, a fake version relies on an eccentric wheel motor, causing vibrations that are quite noticeable in your hand.

Yes, our device can be used with all of the above as long as you are careful and work around them.
