I did a teeth whitening at the dentist years ago. It was the worst experience ever. I have sensitive teeth and even though I told them, they didn't do anything. After that experience, I attempted to do the whitening strips that are all natural but it didn't make the difference I was looking for. Now years later, I decided to try Opal Glow. I let Raiza know my concerns before starting and she explained what she can do to help with the sensitivity. The sessions went by quickly and she always asked how I was doing. She gave me a care card with after care instructions and even followed up the next day to see if I had any sensitivity issues. When I finally saw the final produce, I was amazed! My teeth looks so good! What a HUGE difference! I will keep coming back for maintenence when needed. Thank you so much Raiza for a caring easy process! 10/10 recommend!
