I'll join the chorus of those who can't fault the guy for fixing up his smile. Whether dentures, veneers, or some other dental work, that's a smart move. Good teeth aren't purely cosmetic -- rather, they improve the function of the mouth for necessary tasks like eating and speaking (it seems he sometimes struggles with the latter but has no issues with the former. Sorry. Couldn't help it.). So I agree that it's wise to make good dental care a priority.
There's been some debate about his finances, specifically how much (if any) of his European trip he paid for himself and how he was able to afford it. He strikes me as a very "new money" type -- the sort who spends every cent as soon as it comes in immediately because a whole new world of opportunities has just been opened up to him. I doubt he's saving much or planning for the future, but I hope I'm wrong about that. He's in uncharted territory as a full-time vlogger, and there are fewer safety nets in place for such a career.
