How do you whiten older dentures?

My wife has a set of approximately 30 year old dentures that have been badly stained by coffee and the like. Our grandchildren are beginning to say that she has green teeth and she wants whiter looking teeth. Because they fit really well she does not want to replace them. She has tried all of the soaking products to no avail. Is there any thing over the counter that will whiten them? If not can a dentist do anything other than make her a new set?

You may try some bleach, but you can't whiten fake teeth. If those are 30 years old a new pair may be what she needs.

Reply:My mother, father, and grandmother swear by a bleach/water solution soak overnight. I can remember my grandmother doing this since I was a kid. I'm now 45. And her dentures are pearly white! Oh she uses the typical over-the-counter daily cleaner; but at least once a week, she soaks those dentures in a strong bleach and water solution in her "chopper hopper" overnight to help keep them white and remove stains. And to disinfect she says. Just make sure you rinse and brush them well the following morning.
Reply:see the dentist, they may have a lab willing to replace the few teeth in the existing denture with new ones. I donno how much it will cost or if they willing to do but it is possible (they fix the fallen out teeth on the denture by placing a new tooth in and recooking the denture)
