Yes, this is totally normal. In fact, it is designed to have a small gap so that there is some gap to allow for vibrations. 

It is recommended to replace your brush head every 3 months. However, depending on the condition of the bristles, please replace them soon. 

We recommend to clean the toothbrush at least once a week since there is a lot of bacteria build-up in your mouth and bathroom.

Soocas specially designed the toothbrush head to fit perfectly with the body, so we don't recommend you to use other replacement brush head on NEOS II. Vice versa, please refrain from using Soocas replacement brush head on other brands. 

Yes, you can use NEOS II with braces. The soft bristles are braces-friendly. If you have any questions, please seek professional help from your dentist. 

The NEOS II toothbrush uses DuPont bristles, which offer the ideal combination of softness and durability for most users. Softer bristles may not clean effectively, which could be detrimental to oral health. For users with highly sensitive gums or periodontitis, we recommend using the toothbrush on the lowest intensity setting for a more comfortable experience.

Additionally, 100% of our brush heads undergo a polishing process to ensure rounded tips, preventing any sharp edges that might harm your gums. You can use them with confidence.

NEOS II features a gradual power increase during the first three seconds of activation, designed to reduce toothpaste splatter. We recommend using a pea-sized amount of toothpaste. For better coverage and reduced splatter, apply the toothpaste directly onto your teeth before turning on the device. This method also ensures that every tooth receives toothpaste, improving cleaning efficiency.

Yes you can.
NEOS II Electric Toothbrush is  rated waterproof so you can use it whliler showering.
