Just look at those pearly whites on Britney's boy Jayden when we spotted him and his bro - dressed up in Spider-Man outfits - seeing a movie with mom last night! His chompers are positively blinding, right?

This comes as quite a surprise to us because, back in darker days, K-Fed & Co. accused Ms. Spears of allegedly neglecting their children. The father of two was worried about the boys' alleged poor dental hygiene, not to mention poor eating and sleeping habits, all while they were under Brit's care...

And then in early August of 2007, Britney was accused of putting soda in both her kids' baby bottles. There were also reports of tooth decay from Brit giving Sean and Jayden sugary foods and ice cream.

But now Jayden's teeth are super sparkly! Did Brit get them whitened?
