The only way to change the color of porcelain veneers is to remove and replace them. Whitening strips and whitening gels are effective only on natural teeth. If you're wondering how to whiten your composite veneers, you might be tempted to try a whitening treatment at home. Unfortunately, composite resin does not respond well to bleaching.
The American Dental Association explains that this is just one of the reasons why it's always a good idea to talk to your dentist before whitening your teeth. Dentists are often asked “can you whiten veneers? The short answer is no, but there are tips for dental planning and caring for your veneers that will keep your smile white, bright and beautiful for longer. What you would do is see your cosmetic dentist as soon as you reopen and look at the veneers. They can tell you if the glazing has been removed.
In the meantime, I suggest you buy Supersmile toothpaste. This does the best job of removing stains from any of the toothpastes on the market. It is also the only insurance for both teeth and cosmetic work. Most “whitening” toothpastes use abrasives to remove stains that damage enamel.
Porcelain veneers can also get stains on the sides as the material ages. You can't whiten veneers with bleach like you would with natural teeth, but you can try to make the teeth under the veneers whiter or you can ask a cosmetic dentist to do it for you. Learn 3 ways you can remove stains from porcelain veneers. The three methods used to whiten teeth or remove stains are a teeth whitening system, a soft polishing toothpaste, and an aesthetic dentist.
Always follow the instructions completely when it comes to the teeth whitening system and talk to your dentist before trying to whiten your teeth at home. You can then try brushing your teeth with toothpaste specifically designed to remove the compound that is the cause of stained veneers. A toothpaste with a gentle polish is recommended if you have a small stain around the edges of the veneers. Another option for whitening veneers is to visit a cosmetic dentist.
The porcelain enamel has most likely come off your veneers and a cosmetic dentist can professionally clean them to make them look white again. The worst case scenario is that they will need to be replaced. When you try to whiten the back of veneered teeth, the actual tooth will naturally whiten, which will then be reflected through the porcelain veneer.
