Generally, porcelain teeth are dentures, full or partial, bridges, crowns or veneers, and each has its own method of whitening. A porcelain tooth can not be whitened to a lighter colour than when the tooth was made, but the discolourations and stains that can build up over time can be removed to regain the original colour.
All toothpaste works to help whiten teeth. Whitening toothpaste, although it will remove stains and discolourations, will not work on porcelain teeth the same way it works on regular teeth. For porcelain teeth that are permanently fixed in the mouth such as bridges, crowns and veneers, regular toothpaste is the best method of removing stains. Toothpaste is designed to remove coffee, tobacco, tea or other foods that can discolour teeth. Using toothpaste and a toothbrush is often the best method of keeping porcelain teeth a consistent colour.
ProTech Denture Cleaner
ProTech cleaner is designed for porcelain teeth that are removable. ProTech Denture Cleaner is used by submerging the dentures in the solution for at least 30 minutes a day, although it is recommended to leave the dentures in the solution overnight. This will remove stains from coffee, tea and nicotine, as well as removing possible pathogens that could cause sickness in the wearer. The cleaner should be rinsed off the dentures completely before putting back in the mouth.
Ultrasonic cleaners, such as those made by Sharpertek, can be used to clean jewellery and contact lens, but the ultrasonic cleaners are also used for dentures. Because the dentures need to be placed in the machine, it is only for removable porcelain teeth. An ultrasonic cleaner cleans every part of the denture, which can be helpful considering that submersion and brushing might not clean hard-to-reach areas. Ultrasonic cleaners remove bacteria as well as debris and stains.
