Lower Molar removed will cause other teeth to move?

[timtrice]

An old temp crown (8-10 years) was lost and the entire tooth is dead.  It is #19, a lower-left molar.  I'm being advised by Ortho surgeon implant is the best option; an extraction will allow the last molar on that side to move, possibly even lean and also the two teeth above can drop down and mess up my bite.  

I just want to know if that sounds right.  I'm 31-years-old, which seems to be the common reason he's suggesting I do this.  My main concern is spending $3,000+ on this deal when if it were just for an extraction, I'd be fine with it.  I do not want my bite to get out of it's position though.  How likely is this to occur?

VERY LIKELY !!  Go with the implant option.    I know it sounds expensive but teeth do move!  If you spend that money now, it could save you a lot of money in the future.   I have a friend in his 30's who lost two teeth and he waited too long to get implants.   He has the implants now but his whole jaw had moved out of alignment all because of these two teeth being lost.   It's a sad fact but with the pressure that teeth go through with chewing food every single day of your life, they move if there's nothing for them to be aligned with, either beside them or above them.    Admittedly they do take a while to start moving, but if you do wait too long, who knows what an implant would cost down the track.

This is right . These movment are very likely to happen . to stop this you have to replace the missing tooth.

You have 2 options :

1- Implant , it is the best and will prevent the movment of the teeth and also will prevent the bone lost on the extraction site. 40% of the bone in the extracted site will be lost in the 1st year. So Implant will prevent that.

2- FPD ( Fixed Patial Denture ) which means you use the 2nd molar and the 2nd premolar to help to hold the bridge .

so if you can pay for the implant then GO FOR THE BEST . but if you can't then you have the other choice , but remember that in the 2nd choice you need to prepare the 2nd molar and 2nd premolar . So if they were intact and you don't want to loss 40% of the bone in the extraction sire , then thing again about the IMPLANT .
