My sims disk doesnt work

Hi! 🙂 im having an issue with the sims, because of my disk. over christmas, i was going away to see my family, but i left my sims 3 university life disk out and i have an automatic air freshener. so the freshener got on my disk and completely stained it! i tried getting it off but its on the disk for good ☹️ is there anyway i can change it so i can use one of my other disks instead of my university life one? please answer ASAP 🙂 thank you!

also ive already tried uninstalling all my games and reinstalling them, ive tried registering them to origin, and everything! ive dome so much to try to fix my problem but nothing has worked so far ☹️
