my recent private dentist also told me the same thing - 2D X-ray hard to spot my problem, until few months later when I'm in pain then it's already damn late

didn't really advice me or ask me to do CBCT, only use the normal 2D x-ray they have in their separate imaging room. It could be that the dentist don't have the CBCT equipment, or maybe chose not to use it.

the initial problem was the wisdom tooth and to be extracted because in pain, did an x-ray and found out the wisdom tooth shaped horizontally.

Then months later the tooth beside wisdom tooth started to hurt, did a couple of x-ray, then only realized it got impacted badly by the wisdom tooth before this (who would have known lol). Dentist told me whether to save the tooth by filling or not to save it by extraction, I chose to save it and dentist did filling in. After another month (last week) the pain comes back again and unfortunately had to be extracted out
