Is tooth number LR7 a wisdom tooth?

[worrier]

My dentist advised I have a complex extraction of my LR7 tooth (I'm in UK) to avoid future problems (it hasn't so far caused me any discomfort). I assumed this was a wisdom tooth. I've never had wisdom teeth removed and this LR7 is furthest back. But I've just read on the internet that LR8 is the wisdom tooth. I've been so worried about having my wisdom tooth removed on hearing of possible complications, especially in older people like me (I'm 73), but now I'm confused. Is it possible I never had a LR8 wisdom tooth and that the tooth to be extracted, LR7, is not a wisdom tooth after all?

Yes that is possible. LR7 is your second molar. There are people that don't develop all their wisdom teeth or even none at all.
