After two tortuous years of being braces, I knew I would be in the market for a teeth-whitening system. As great at my orthodontist office was, they were quoting me severalthousand rands for their system, which wasn't palatable to me at all. So of course, I chose to research alternatives and came across OneSmile, which has great reviews. I've been using the product for a few days now, and I can certainly see a difference. My husband and several others have commented that my teeth are notably whiter. I still have a bit to go in the process, but I'm looking forward to the final result. What I appreciated the most was how easy everything was to set up. There's no complicated equipment, just an instruction manual and, if necessary, YouTube videos. I will readily admit that I was concerned about the teeth guard that came with it. I wasn't sure how a one-size-fits-all approach could work, especially when my orthodontist told me that he would custom-mold one for me. But it does work and covers all my teeth with no issues. I'm seeing even whitening all around. I would definitely recommend this to anyone looking to improve the aesthetics of their teeth. In my case, it came at an opportune time. Right after my braces came off, I accepted a job offer in a different city and will be relocating there. Not only do I have a fresh start with my career and location, I'll be going there with straight teeth and meeting my colleagues for the first time with WHITE teeth. Lekkker!
