Denplan has made a significant £26k donation to MacMillan Cancer Support.
Three hundred Denplan staff and member dentists raised £26,888.55 for the cancer charity throughout 2012.
Steve Gates, managing director of Denplan, said: "Our staff have been working hard to raise funds through cake sales, raffles, events and member dentist donations to help people in need. We're proud to have been able to make such a significant contribution."
Lisa Murphy, fundraising manager at MacMillan, said the charity was "very grateful" for the Denplan support that will continue for the next two years.
