Wisdom Teeth: Implant Alternative?

[MidsummersEve]

Hello there everyone. I am in the process of signing up for my new health insurance cycle this coming fiscal year. I need to make a decision about a medical spending account, and the decision is how much money I should put into it.
This question however lies on a much deeper and more painful topic.

I have a long gloomy dental history. I have done better since I've grown up, started brushing and flossing regularly and not avoiding the dentist.
My history however has left me with molars that have multiple fillings each, sensitivity(some very deep filings) and even one crowned root-canal. My last dentist tried to pressure me into cutting out my wisdom teeth, but for the first time in my life I really listened to my mother. She told me everyone in our family has has had them and they've developed cavities at most, but nothing else. This led me to start thinking I could use these real teeth in the future to replace some of my bad-habit results.

I have wondered for some time now, if I should keep my wisdom teeth and when the time comes simply remove my molars. One tooth is on the verge of a root canal because the recent "Redone" filling by my EX-dentist is so sensitive that I haven't eaten anything other than pudding on that side of my mouth for over 6 months. I haven't seen a lot of information about this topic online and so I am digging a little deeper and asking for a few educated guesses.

I'll take it to the next level even. People say wisdom teeth decay easier and are harder to reach. If these teeth are pulled into the place of my former molars AND if I get sealants for any really deep tooth crevasses, I feel this is a more natural option than getting more fillings, root canals, crowns, and then eventually implants down the road.
Heck I'll even risk guessing it's cheaper in the long-run than getting all the work above over time.

Any thoughts?

you cant move wisdom teeth into the place of your former molars. even if it was possible wisdom teeth have a different, weaker root system not acceptable for the heavy chewing of regular molars. thats why wisdom teeth are the easiest to extract. once wisdom teeth get decay its much easier too pull them than restore them. not only are they more difficult for you to clean they are more difficult for the dentist to fill.

I am almost 60 and still have my wisdom teeth, so don't fix it if it ain't broke.  I have never heard of being able to use your wisdom teeth in place of molars. I would have the root canal on the one tooth.  Wisdom teeth are harder to reach, but you can keep them clean.
