<human>: I'd like to know if it is safe to use a sonic toothbrush.
<bot>: It depends on the type of sonic toothbrush you are using and your personal preference. Sonic toothbrushes can be beneficial for removing plaque, but they should not be used excessively or too frequently as this could damage teeth. Additionally, some people may find that sonic toothbrushes can cause discomfort due to their vibration. So it's important to consult with your dentist before deciding whether or not to use a sonic toothbrush.
