Although the Philips Sonicare ExpertClean 7300 appliance is primarily designed for adults, it can theoretically be used in a family if everyone uses their own brush.

### Compatibility with children's brushes:
- The ExpertClean 7300 device is compatible with Philips Sonicare's Easy Click-on Brush Heads. However, there are no specific children's brushes offered directly for the ExpertClean 7300 model.
- There are separate models and brush heads for children, such as the Philips Sonicare Kid's Brush Heads, but these are designed for other models such as the Philips Sonicare For Kids and are not directly compatible with the ExpertClean 7300.

### Family use:
- Family members can each use their own brush, but it is important that each brush is cleaned and stored separately to ensure hygiene standards.
- It is possible for several people to use the appliance as long as each person uses their own brush and the brushes are replaced regularly.

It is advisable to use toothbrushes and models specially designed for children to fulfil their specific needs.
