“In my experience this system is great for those with sensitive gums. I use the mouthpiece and the mint gel for about 10 minutes at a time and have had no issues with irritation to my gums. I've used it 4 times and can already tell a great difference!”
“I got great results. I still have some gel left that I use for touch ups every now and again. I def recommend novashine if you want to to brighten your smile”
