I got my teeth whitened by Tamar at T & G and love the results. Before we started, she determined what my starting tooth shade was. I did the upgrade and had three back to back sessions that each lasted 15 minutes. At the end, we went outside to compare my results, and I was 8 shades whiter! I am so pleased with the results. Tamar is very professional, and obviously very knowledgable about the process and the product. If you are thinking about getting your teeth whitened, call T & G, you will love the results.
