Re: How bad can dentures be?
What toothfairy said is absolutely right. Dentures are a good alternative for bad teeth but not a good one for teeth that are still in reasonable condition. But another factor is cost and the life expectancy of any natural teeth that are repaired. For instance, $20,000 is a lot of money to spend on teeth that might only last a couple of years. Assuming you're in the US or Canada, a complete set of dentures with simple extractions will likely cost in the $4,000-$6,000 range. The cost could increase significantly if any other oral surgery is needed and/or if you choose implants. Lower dentures are a pain wihtout some kind of anchor such as natural teeth or an implant. I have a partial lower denture which is anchored by two remaining eye teeth. If/when they give out I'll have implants put in.
How bad can dentures be? Well, they're not bad at all....if you don't have any other choices. Consider your options carefully, especially where wearing dentures and the possible difficulties that Sjogren's might present . Once your natural teeth have been extracted there's no putting them back in. I would strongly suggest you keep as many natural teeth as you can.
