Being i am in sales and i am talking with tons of people every day I have always wanted to get my teethe whitened. I was a bit worried it would not work and i would waste money. I bit the bullet and I set up a meeting with Ingrid. She made it such an amazing and comfortable experience for me. My teethe were very white when we were finished. I have already to several friends and I HIGHLY recommend Gleaming smiles.
