Obviously, dentures can be stained by every day things such as nicotine, alcohol, food and drink just like real teeth. But it is far easier to eradicate these stubborn stains than you would think!
Remove your dentures and brush them with toothpaste- just as you would with regular teeth. Immerse the dentures in hot water mixed with 3 tablespoons of household bleach. Leave the to soak for ten minutes and then run them under warm water whilst scrubbing them with a toothbrush again. Rinse the dentures under warm water very thoroughly to wash away all of the bleach. Brush the dentures for a third (and last!) time with toothpaste for minty freshness. This can be repeated every 4 weeks!
Another home remedy for the whitening of dentures is to soak them in distilled white vinegar. This acts as a sanitizer, helping to destroy germs and bad odours. Again, it helps if you brush the dentures with a toothbrush to remove plaque. Dentures can also be deodurized using baking soda on a toothbrush.
However, if you want to skip the purse-friendly home-made remedies and don't mind splashing your cash, a wise investment would be Efferdent Anti-Bacterial Denture Cleanser available online or in any supermarket. The tablets odour-causing bacteria, reduces plaque and dissolve stains.
A word of warning- never use regular tooth whitening products on your dentures. This may damage them and you will probably have to cough up for a new pair!
