There's been an outpouring of support for a four-year-old girl from Montague, P.E.I., who is in need of dental care.

Olivia Clow needs nitrous oxide gas to help with three fillings, but it's not covered under the province's Children's Dental Care Program.

Olivia's mother, Margaret Clow, is on social assistance. She said she can't afford the gas, which would cost $200, or the transportation to get to and from the pediatric dental clinic in Hunter River, about 70 km from their home.

Since the story first appeared on CBC News last week, there have been at least 10 offers of help called in to the dental clinic.

"Some people that are in shock of the system not being able to help parents in this situation," said clinic manager Vivian Osborne.

"And I have heard from a lot of people that are concerned with this patient not getting her treatment done and have offered financial assistance for her. They're all anonymous donations."

The province has said it will cover the cost of transportation for Olivia Clow to get to the clinic in Hunter River.

It's also now reviewing the issue of funding for nitrous oxide.
