Ultimately, the results are largely dependent on the client’s natural teeth composition. Whitening By Julie has some of the highest quality teeth whitening machines and products in the market, much like the ones at your local dentist. The difference can’t be noticed so much in the quality or color, rather the cost. Dentists can charge anywhere from $400- $1000 for essentially the same or similar results. That said, we do recommend you visit your dentist regularly and as needed.
