Debbie Gagne has also been ordered to pay back every penny she stole from Image Dental Studio in Red Deer.
Gagne pleaded guilty last December to one count of fraud over $5,000.
She was originally charged with 231 offences.
She stole the money while working at the dental office between 2009 and 2011.
The judge granted Gagne's request to serve her sentence at the Edmonton Institution for Women.
