エアジェットX5 歯ブラシヘッド - ウルトラホワイトニング

I’ve been using it for 7 months. I’m a regular smoker, so I had lots of yellow stains on my teeth.
My gums aren’t sensitive at all, so I’ve been using the Clean mode this entire time.
I took photos half a year ago, planning to ask for a refund if there was no improvement.
Surprisingly, the brightening and stain-removing effect is amazing, way better than I expected. Totally worth it!

OH MY GOD! I’ve been using this for a month, and today I felt something gritty… my tartar literally fell off while brushing! I’m shook. This brush is insane."

I don’t go to the dentist regularly, so tartar built up over time. I’ve been using this toothbrush for about 3 months, and today I felt a piece come loose while brushing — I spit it out and it was gone! I was totally shocked, so I had to come back and leave a review.
