Are implants worth all of the money in your opinion?

Q. Hi i\’ve had dentures in now since a very young age because i suffered from bad gum disease. I\’ve never had any problems with them until now i had a new set made because my others were falling apart but they won\’t stay in. Do you think this is because of my gums or the fact they haven\’t been made right? i heard mini implants can hold them in place? but is it worth all the money in your opinion? thank you,
