Another possible reason your veneers have taken on a black or blue-gray tint is that they were not properly bonded to your teeth. Without proper bonding, substances can leak between your teeth and veneers. These substances can cause discoloration, which is not a common occurrence and a preventable one.
Dental Restorations
That's because this material, along with glass ionomer, acrylic, porcelain, and metal crowns, may appear blue-gray at the tooth's surface due to the metallic color showing through a translucent enamel or porcelain surface.
Veneers are cemented onto teeth. In some cases, the cement used in the attachment process can become stained, thus causing the veneers to appear darker. If that happens, your cosmetic dentist may have to remove the veneers and reattach them with fresh cement.
"Blue stain” spots on the veneer sheets are a reaction of tannic acid from the wood and the iron in the steel of the knife and/or the pressure bar. This phenomenon can be found in wood species with high tannic acid content such as red or white oak, cherry and walnut.
Veneers may not be able to be made whiter with treatment, but that doesn't mean you can't make them look better in general. In addition, regular dental visits will maintain your veneers as spotless as possible since professional cleanup can help to eliminate surface stains.
With proper care, your porcelain veneers will stay pearly white for as long as ten years, and by then, it will be time for the recommend repair or replacement of your veneer.
While veneers are often made out of stain-resistant materials, they can be susceptible to staining over time, especially if they are made from composites. Research shows that porcelain veneers do not get discolored or stained easily, but those made from composite resins do.
Dental veneers are comprised of long-lasting, high-quality materials that do not discolor like enamel. Instead, they retain their brightness over time.
You can ask your dentist for a refund. If you want your dentist to replace your veneers, insist on a third set of porcelain veneers in the color of your choice. Remind your dentist that you want clear, tint-free bonding resin that will not alter the shade of your veneers.
When veneers aren't properly bonded, food or drink can seep behind them and cause discoloration. In this case, they will have an uneven gray color. It also promotes a buildup of bacteria and can cause tooth decay. In either case, an expert cosmetic dentist can identify the problem and resolve it.
The shine on veneers is created by the glaze put over them. This glaze is critical because creates the shine so the teeth don't look flat or dry. It also gives the veneers their stain-resistant quality. The extra shine on your veneers is a problem with your glaze.
While crowns and veneers cannot absorb stains like natural tooth enamel can, they can still lose their luster over time. At home, patients can use a gentle polishing toothpaste for a whiter appearance.
Dental restorations that include metal and porcelain crowns, acrylic, glass ionomer, and silver-colored amalgam can give the appearance of blue or gray teeth.
Some mouth rinses have dyes or colorings in them that can adversely affect the teeth and cause stains to occur giving off a “bluish” hue to one or multiple teeth. The dyes may stick more easily if poor hygiene habits are involved.
Composite fillings are made of a resin and plastic material that is placed into the cavity while it's soft, then hardened with bright blue "curing" light. It's a popular choice because it can be matched in color to the shade of a person's existing teeth, so it's not as obvious as a silver amalgam filling.
Another possible reason your veneers have taken on a black or blue-gray tint is that they were not properly bonded to your teeth. Without proper bonding, substances can leak between your teeth and veneers. These substances can cause discoloration, which is not a common occurrence and a preventable one.
The veneers are chipped or cracked
Veneers that are chipped, cracked or just looking a bit worn down are ready to be replaced. Porcelain is durable, but that doesn't mean it can't be impacted by biting on hard food, or just become worn over time.
So, Is Drinking Coffee with Veneers Allowed? In short, the answer is “yes.” You can drink coffee with veneers. Even better, high-quality materials like porcelain are significantly more stain-resistant than your natural teeth.
Veneers are bonded or cemented onto your teeth depending on the type, and when bonded there is the possibility of micro-leakage of the bonding material which can attract particles leading to a stained appearance. If this is the case, the veneers can be re-bonded if necessary, and the problem should go away.
While dental veneers attach to the teeth, they can fall off in certain situations. Dental veneers can slide right on off if the dentist misapplies them. Physical contact with the teeth and the aging process can also cause porcelain veneers to fall off.
#1: Gel Toothpaste
Gels are much gentler and are usually recommended for patients with veneers and other custom dental restorations. Avoid any toothpastes that contain hydrogen peroxide or baking soda. These ingredients can be too abrasive and may damage your porcelain veneers.
Can I whiten veneers? Unlike our natural teeth, we do not recommend using traditional whitening treatment on veneers. Teeth whitening products cannot change the colour of the veneers – but they can change your natural teeth, which will likely result in an uneven toned smile.
Porcelain veneers are naturally resistant to stains, and they do not respond to the bleaching agents in whitening toothpastes. In fact, many ingredients in whitening toothpastes are abrasive and can be too harsh on porcelain veneers.
Can You Whiten Veneers? This may not be the news you wanted to hear, but veneers typically don't respond to whitening techniques like whitening gels, baking soda, or even professional whitening. Whether you have porcelain or resin veneers, whitening them won't work.
