Her position with an orthodontist regularly placed her in the lab remixing and adding alginate to the tongue area of impressions or grinding out stone from the tongue-area of models. Grinding raised stone "dust" in the air. And Doris didn’t like that her hands were cracking and sometimes blistered. The entire process seemed to her altogether messy and time-consuming. Doris Craig imagined a better way.

She dreamed of a cost-effective, premixed tongue filler that popped out clean with only wash-away residue. Bing! Necessity, as they say, is the mother of invention. Rather than waiting for an inventor to have the idea, Doris went to work and created Wonderfill. By the end of March 2000 she had a product that her employer’s staff didn’t want to be without — ever again.

Lengthy searches for just the right smell and texture ended in a light pink, peppermint scented tongue filler that is now known as Wonderfill — and available today through distributors to all practices and labs that are tired of the daily grind.
