On each side; my canine, first premoler, and second premoler are yellower than the rest of my teeth. My front four teeth are fairly white however. This is noticeable when I smile and I think it looks weird. I would much rather them all be the same shade. I had thought aquafresh white trays would help with this, though the tray do not fit well in my mouth. They are too small and move around. I'm only on day 2 but they seem to be making my teeth look blotchy instead of giving a uniform white. So say the least, I'm not impressed. Though I realized, even if they were a good fit they would not even out the shade on the sides because the front four teeth would always be a couple shades ahead. Does anyone have advice to correct this and give me a uniform white? Could I use whitestrips and just do an extra treatment on the sides. If so, which kind? I've never experimented with them so I don't know if that is possible... Look forward to some advice.
