FAQs

How does it clean my mouth?

The PrecisionFit Mouthpiece is designed to wrap around your teeth, allowing sonic vibrations to clean multiple surfaces at the same time.

With 18,000 ultra-soft nylon bristles distributed across the mouthpiece, it delivers consistent, full-mouth contact for a more even and effective clean.

What makes this mouthpiece different from a regular toothbrush?

Traditional toothbrushes clean one tooth at a time and rely heavily on technique.

The PrecisionFit Mouthpiece is designed for full-mouth coverage, helping reduce missed spots and uneven pressure while delivering a faster, more consistent brushing experience.

How often should I replace the PrecisionFit Mouthpiece?

For optimal performance and hygiene, we recommend replacing the PrecisionFit Mouthpiece every 3 months.

Regular replacement helps maintain effective cleaning and ensures the best overall brushing experience.

Is it more effective than a traditional toothbrush?

The mouthpiece is engineered to support deeper, more consistent cleaning by reaching more surfaces at once.

Its design helps improve plaque and bacteria removal when used as part of a daily routine.

Can it help reduce bacteria in my mouth?

With regular use, it helps remove up to 99.99% of bacteria from the surfaces of the teeth, supporting improved oral hygiene and a fresher mouth feel.

By maintaining continuous contact across the mouth, it supports more uniform cleaning, which contributes to improved oral hygiene and a fresher feeling throughout the day.

Is it gentle on gums?

Yes. The mouthpiece uses ultra-soft nylon bristles combined with a flexible structure to balance effective cleaning with comfort.

This design helps minimize excessive pressure on the gums while still maintaining thorough daily cleaning.

Does it fit all mouth sizes?

The mouthpiece is designed to fit most adult mouth shapes and sizes.

Its flexible construction allows it to adapt naturally to individual dental anatomy for a secure and comfortable fit.

How do I clean it after use?

After brushing, rinse the mouthpiece thoroughly with water and allow it to air dry before storing.

Proper rinsing and drying help maintain hygiene between uses.
