Hi there, Thank you for sharing your feedback with us. We are sorry to hear about the experience with your Philips Sonicare toothbrush. This is not the experience we want you to have. We suggest you try a few possible causes and solutions to see if you can fix the issue. Sonicare toothbrushes use powerful vibrations to clean your teeth. The noise is louder than what a manual toothbrush makes. Your toothbrush will be noisier if you switch it on without a brush head. Make sure your toothbrush always has a brush head attached. A loose brush head could be the cause of your toothbrush's unusually loud noise. Make sure the brush head is firmly attached to the handle and isn't moving about. The handle and brush head will still have a tiny gap there to allow for vibration. Disconnect the brush handle from the head. Switch on your toothbrush. If the noise stops, the brush head is faulty or worn out. If the noise is still loud or unusual, the toothbrush may be broken. Your brush head has to be changed for a new one. We recommend replacing your brush head every three months. We hope this was helpful. If the issue still persists, please get in touch via Social Media. We’re available on Facebook (@Philips) and Twitter (@PhilipsCare). Don’t worry, if you don’t use Social Media, you can also reach out to us via the contact page: www.Philips.com/contact. Hope to speak to you soon! Best regards, Philips Consumer Care
