Unless the dentist told you one of the teeth are actively infected and thus time sensitive (to prevent infection from spreading elsewhere for example), and since you're not in pain, I'd suggest re-scheduling at least to give yourself more time to think about it. All surgery does come with risks and shouldn't be rushed into if you're unsure, imo.

If you can, ask the surgeon about how close your nerves are to the teeth and what they think the risk of nerve damage is for your particular case, so you have more information. And check the reviews and credentials for the surgeon, and make sure that it's them who will do it personally and not assistants allowed in the fine print.

Personally, if the wisdom teeth aren't causing any problems and the only reason to remove them is "they might cause problems in the future", I'd leave them alone. Especially if they're not sideways/impacted, but even then. But it's your body and your decision. And I am not a doctor or a dentist of any kind.

But probably best to take the time you need to feel comfy with the decision if you need to, either way.
