First the dentist put a plastic thing in my mouth to keep my mouth open and my lips out of the way. Next he put some folded paper in my mouth to protected the bottom most part of my gums and he then coated the gums right near the teeth with a protectant thing. Once that is all done the bleaching gel is put on my teeth and the blue zoom light placed over my teeth.
The first cycle was bearable. My teeth felt quite hot and dry which was a weird sensation. I found it was easier for me if I kept my tongue in one spot and didn't move it. By the end of the first cycle there were some faint zing feelings but very easy to bear.
The second cycle started to get a bit more intense halfway through. Some more powerful zings this time. It was still tolerable so I kept going.
Halfway through the third cycle is when I felt it was too much for my teeth. The zings were quite powerful now. It is an odd feeling, like an intermittent electric shock, and it is completely random as to which tooth is goes through! The dentist stopped the machine and uncovered my mouth.
To be honest the aftershocks were worse than what I was experiencing in the third cycle itself. The dentist put some numbing stuff on my teeth, I rinsed my mouth, drank some water, and took some panadol. It especially increased the zings when i opened my mouth so I tried not to speak and opened it long enough to get a picture taken. On my walk home I had to walk really slowly. When I got home I put on the sensitive toothpaste I was given and it helped a lot. It took probably about 2 hours for the shocking zings to go away. At this point I was okay to eat, and managed to eat a hot meal with a cold drink through a straw. I was still getting the very occasional zing, so I took some advil, curled up in bed and took a nap for approximately 2 hours. When I woke up the zings were completely gone and I was left with just a very dull sweet ache feeling which is fine!
The results are absolutely amazing despite only finishing 2.5 cycles. The pain was definitely bad at first but went away relatively quickly and 7 hours after the procedure I can definitely say it was worth it.
