How can I get less pointy canine teeth? What can I do, and how much will it cost? (Photos)

First of all, I have three major problems with my smile. They’re not straight enough, not white enough, but the most important thing is that my canine teeth are too pointy. They ruin my smile tremendously and I want to get them fixed. I didn’t care too much for my smile when I was in high school but now I want to work on it. So what can I do, and how much will it cost? And if there’s any other tips on how to improve my smile based on the pictures that would be appreciated. Thank you!
