A YOUNG woman has knocked her teeth out after she accidentally smashed a trolley into her own face.

The 21-year-old has been taken to hospital with lacerations to her chin and missing teeth after she had a shopping trolley accident at Helensvale Plaza.

Emergency services were called to the busy shopping centre carpark at about 3pm after receiving reports a woman was injured.

“It looks like she’s accidentally pushed the trolley into her face,” a Queensland Ambulance spokeswoman said.

“She has had a bad fall and has smashed her teeth out.”

The woman is recovering in hospital in a stable condition.
