Whitening: It is not possible to whiten dentures like natural teeth because dentures are made of plastic. To minimize staining, properly clean your dentures daily to remove food and plaque bacteria. Brushing with a denture brush or soft toothbrush will prevent dentures from becoming permanently stained and keep your mouth healthy. Moisten the brush and apply a non-abrasive soap or denture paste (regular toothpaste is too abrasive). Brush every surface, inside and out, scrubbing gently. A variety of over-the-counter denture cleanser products may be safely used (by following the manufacturer’s instructions) to remove most stains. Do not use bleach on your dentures unless your dentist or prosthodontist gives you special instructions on using bleach. Dilute household bleach can be used to clean and disinfect your dentures, but don’t use bleach until you see your denturist for instructions. More stubborn stains may require removal by your denturist.
Brushing: Do not brush your dentures with normal toothpaste. Toothpastes are designed to be used on teeth, and they often contain materials and chemicals that help whiten and strengthen teeth, but may harm dentures, which are made of a very durable plastic. Even though the plastic is strong, it is not as strong as the enamel of teeth and may be scratched by using toothpaste to clean your dentures. You should use a dish washing liquid and a special denture brush to clean your dentures by hand every day. After rinsing them thoroughly, soak your dentures in water-based cleaning solution overnight.
Repairing broken dentures: The best solution is to return to the denturist who made your dentures and have the cracked denture repaired professionally. It may seem easy to fix, but it is important that the repair is done correctly to prevent problems with chewing and to avoid any sore spots. The denturist also needs to check the denture and adjust it after it is repaired. The denture may be too old and may no longer fit closely to your gums, and you may need a new denture.
