Hey HunterMilo! 
Unfortunately, once TikTok messages or comments are deleted by users or moderation, they’re pretty much gone from TikTok’s servers - there’s no built-in recovery feature. However, if you’re monitoring someone’s TikTok activity (like for parental control), Eyezy can capture and log all social media interactions in real-time before they get deleted!
For personal use, you could try enabling TikTok notifications so you get the full text pushed to your notification panel, which sometimes stays even after deletion. Are you trying to monitor your kid’s TikTok interactions or just curious about missed content?
