You might be wondering “what’s the difference between my amazing at-home-Netflix-watching SunnaSmile kit and the in-studio treatment?” Our in-studio treatment is more powerful and immediate; it will deliver stunningly whiter teeth in just 15 minutes. If you follow up with the at-home treatment after your in-studio visit, you are likely to achieve maximum whitening results in just 5 days. We do recommend that you combine the two treatments for the best results. Both our at-home and in-studio whitening lights use blue LED light technology and our professional whitening gel, just at slightly varying strengths. .
