Yes, it is possible to get cavities under veneers, but only if you don't brush and floss your teeth properly. Although veneers add a layer of protection by isolating teeth from the surrounding environment, it's still possible for decay to form under and around the veneer.
It's important to understand that although your teeth are somewhat protected by veneers, veneers do not stop tooth decay.
As for the underlying tooth or teeth involved, nothing bad happens. Since a dentist only has to remove a small amount of enamel, nerves and roots are never touched. With the veneers in place, the person's natural teeth remain intact. The natural teeth simply serve as the foundation for the new veneers.
This could be caused by a gap between your tooth and the porcelain veneer that wasn't bonded well and has allowed the stain to enter there. It could also be that there was some bonding composite on that line that wasn't polished well. The stains may just be on that bonding agent.
Tooth decay
When layers of enamel start to get worn away by the bacteria that is present in the mouth, it can form cavities. The resulting decay can end up turning a brownish colour. These will show up as spots of brown in and around the front and back of the teeth.
Tartar buildup is most common between teeth and along your gum line. The tartar itself is porous and is highly susceptible to discoloration and staining. Foods, beverages, and other factors can turn it a noticeable brown color as a result.
In the case of porcelain veneers, they are designed using different layers of materials that mimic each layer of your teeth. This gives the veneers natural and pleasing aesthetics. Since both the composite and porcelain veneers are made from opaque materials, your teeth will not be visible under them.
Keep in mind that veneers are permanent and require preparation (light shaving) of your natural teeth. Once you receive them, you can't go back to your natural teeth.
The dental veneers will chip or crack or get worn down. Composite or porcelain veneers can be durable, but they can start to wear down and may even crack over time. Your tooth supporting the veneer can become decayed.
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.
On average, porcelain dental veneers last about 10 - 15 years, though 10 years seems to be the most common lifespan. Composite veneers last for 3 years, on average. Determining their longevity comes down to two things - the veneer itself and the bonding material that holds it in place.
Veneers are not affordable like teeth whitening or dental bonding and will likely cost upwards of $ 2000 per tooth, whether you get traditional veneers or composite resin veneers. Therefore, as long as you are willing to endure the process and the financial costs, you can replace the surfaces as often as you want.
Veneers are among the strongest and most reliable dental restorations and, when cared for properly, there is no reason they should not last for several years. Forever, however, is unlikely. Even with the best of care, porcelain veneers can only retain their bright and attractive appearance for 10-15 years.
You cannot remove your porcelain veneers. Dentists bond veneers to teeth, and removing them requires professional equipment and the skill of a cosmetic dentist. You can risk damaging your gums or teeth if you try it yourself.
Replacing veneers typically happens about 15-20 years after they were placed. Some of the signs that it's time to replace your porcelain veneers are that they are chipped or cracked. Replacing veneers is similar to the initial installation of the porcelain veneers.
Dental crowns are typically the best option if your tooth is very damaged, has a large filling, or has undergone a root canal, since the tooth enamel is more compromised and will need better protection. Porcelain veneers, on the other hand, are best for purely cosmetic purposes.
Veneers do not stain as easily as the natural enamel found on your teeth; however, they can still become yellow or discolored over time. Surface stains can develop after prolonged exposure to highly pigmented drinks such as red wine and dark coffee.
The sure sign of a fake-looking porcelain veneer is that they are too white or too bright. There's an artificial whiteness that a good cosmetic dentist can identify and avoid. Instead, the porcelain veneer should be stain-free but matched to your other teeth.
We can always make upper veneers whiter than the lower teeth without making your smile look unnatural. Because lower front teeth do not show as much, it is natural to have whiter teeth on the upper. In most cases, we do not have to do the lower teeth.
Can tooth decay be reversed? Yes, if it is caught early. Tooth decay is only reversible in the beginning stages when it has only affected the enamel or the hard outer protective coating of the tooth. Once tooth decay has progressed through the enamel into the softer, inner part of the tooth, it is irreversible.
Tooth decay: One of the leading causes of teeth turning black is tooth decay, which can result from the build-up of plaque and tartar. Poor oral hygiene can result in tooth decay, although this is reversible in the early stages. However, when teeth turn black further treatment is necessary.
Demineralization: The initial stage of tooth decay comes in the form of white or brown spots on the surface of the tooth. This occurs when enamel is weakened and is at risk of being stripped away. Reversing decay at this stage is possible with enamel-fortifying, remineralization toothpaste.
In Australia, a Composite Veneer varies from $300 and $600, and the cost of each Ceramic Veneer varies from $660 to $1,825. The cost of getting veneers can vary depending on the number of veneers, scale of treatment required as well as the type of veneers that you get.
