Public dental treatment is being criticised after data from Queensland Health shows almost 150,000 Queenslanders are waiting to see a dentist in the public health system.

The State Government is unable to reduce the large number queuing for treatment despite the public system already seeing thousands of people per month.

Callie Westbrook, a 36 year old woman from the Sunshine Coast who has been on and off the waiting list for six years, says the prolonged wait has taken a toll on her teeth and now avoids going out in public places.
