Positive Reviews for SmileSpa San Diego: Customers have raved about their experiences at SmileSpa San Diego, particularly in the teeth whitening service category. The company uses a peroxide-based chemical chemistry in their photosensitive teeth bleaching gel which helps to hydrate teeth and prevent sensitivity during the process. One of the unique features of SmileSpa San Diego is their patented gel applicator, AppliaBrush(tm), which ensures that the gel is only applied to the teeth and not the gums, eliminating the risk of gum irritation. Another standout feature is their Infinity(tm), Pro SL LED lamps, which utilize a cold-blue light to speed up chemical reactions, resulting in shorter treatment times of only 15 minutes. Customers have praised the cleanliness and calming ambiance of the studio, making them feel relaxed and at home. They have also commended Rachel, the technician, for her thorough instructions, years of experience, and ability to make them feel comfortable throughout the process. Many customers have been delighted with the noticeable results, with teeth lightening several shades and achieving a brighter, whiter smile. The positive reviews highlight the professionalism, friendliness, and expertise of the SmileSpa team, leaving customers satisfied and eager to return for future sessions.
