Teeth Gel Syringes 22% Carbamide Peroxide, 10 Tooth Bleaching Gel 3ml Syringes

This takes time like 2-3 hours to notice a decent difference. I like it and it's very mild. Do you time I switched to 36% and am very happy although I have noticable sensitivity...milder but noticable for a few days. Although I see the same results or a bit more in only one hour but will bleach gums. This strength won't badly bleach gums if you get a little on it. Use it for 3hrs then I use a remineralizing paste after to reduce sensitivity made in Switzerland. Not sure if it's great but it seems to help. Don't drink coffee, tea, or wine for 24+ hrs after. I used this with custom fitted trays I had made online. Custom trays cost maybe $120ish but really REALLY get you the great results if you have teeth that aren't in a perfect row. Overall very happy with the gentle results and if you have 3hrs I recommend them.

GOOD!

an effective invention..

22%カルバミド過酸化物のホワイトニングジェルを購入しました。 マウスピースで約2時間使用しましたが、歯がしみる感じや表面のツルツル感がほとんどなく、ホワイトニング効果も体感できませんでした。 以前使ったホワイトニング剤では、しみる感覚や歯の表面の変化があったため、今回の商品は薬剤が劣化しているのではないかと感じました。

I would not hesitate to suggest this product. Good value and good product
