Our practice

A neighbourhood dentist you'll actually look forward to seeing.

Tucked on The Triangle just off Cobden Avenue, O'Callaghan C has been part of the Portswood community for years — a small, friendly surgery where patients are recognised by name, not by file number.

We believe NHS dentistry doesn't have to feel rushed or impersonal. Every appointment gives you the time, attention and honest advice you deserve — whether it's a routine check-up or something that's been worrying you for weeks.
