is it possible to straighten your teeth at home without dental care?

Only teeth in my mouth that are not straight are the first two fronts. How can i fix that if i can't afford going to the dentist?

Well... for one... If it's just your front teeth that are not straight then it won't cost a lot of money. But they might put braces or Invisilign on your teeth. Your teeth may be straight, but maybe they're not even with your bottom teeth. Like your top teeth go over your bottom teeth. Or the other way around. It is not possible to straighten your teeth without dental care.
