Veneers are thin ceramic or composite shells bonded to the front surface of the teeth to create a perfect smile. Over time, even the highest-quality veneers can change shade or lose their original shine. This is a natural process linked to external influences and changes in the underlying teeth. Here’s what can be done if your veneers have darkened.
Types of Veneers
The material your veneers are made from largely determines their durability and resistance to staining.
Ceramic veneers are fabricated in a dental laboratory using individual impressions. Their advantages include excellent aesthetics, high biocompatibility and low porosity. The material is resistant to food colourants and maintains its original shade, brightness and gloss for a long time.
Composite veneers are built up directly in the patient’s mouth by the dentist. Composite resin is more porous than ceramic, which makes it more prone to staining from coffee, tea, tobacco and berries. Composite restorations lose their shine faster, require more meticulous care and need regular polishing.
Why Veneers Darken or Lose Their Shine
This may be due to external or internal factors.
External factors:
- regular consumption of staining foods and drinks (coffee, red wine, soy sauce, berries), as well as smoking, leads to the formation of a persistent pigmented film on the veneer surface;
- use of abrasive toothpastes or incorrect brushing technique causes micro-scratches and roughness — pigments penetrate these microdefects more easily, which results in visible darkening.
Internal factors are most often related to the condition of the luting cement. Over time, under the influence of moisture and temperature changes, the bonding material may change colour. This appears as a yellowish or greyish line along the margins of the veneer.
When the Darkening Comes from the Natural Tooth, Not the Veneer
Sometimes the problem is not the veneer itself but the tooth underneath. Veneers, especially ceramic ones, are semi-translucent, so their appearance depends on the colour of the natural tooth structure beneath them.
If the darkening is localised, for example around the neck of the tooth, this may indicate secondary caries developing under the veneer. In this case you should see your dentist immediately to remove the old veneer, treat the tooth and place a new restoration.
Another common reason is the natural age-related darkening of dentine. As your own teeth gradually become more yellow, a visible and unaesthetic contrast may develop between them and the veneers, creating the illusion that the veneers themselves have darkened.
Can Veneers Be Whitened?
Traditional whitening methods that work for natural enamel do not work on veneers. Peroxide-based whitening gels act on organic pigments in natural enamel. Ceramic and composite, however, are inorganic materials and do not respond to these chemicals.
To restore the original appearance of veneers, they can be professionally cleaned. This means an in-office hygiene procedure carried out by a dentist or hygienist. Using ultrasonic instruments, an Air Flow system and special polishing brushes with fine pastes, the clinician removes plaque and calculus from the veneer surface. After that, the veneers are polished to restore smoothness and shine. This procedure removes all external deposits and is the most effective way to “brighten” veneers.
If professional cleaning does not achieve the desired result, the veneers can be replaced.
Safe Ways to Maintain the Whiteness of Veneers
Brush your teeth twice a day with a soft or ultra-soft toothbrush and a non-abrasive toothpaste.
Use an irrigator to remove food debris and plaque from hard-to-reach areas, especially along the gumline.
After drinking coffee, strong tea, eating fresh berries or drinking wine, rinse your mouth with plain water. It is better to drink staining beverages through a straw to reduce contact with the front teeth.
See your dental hygienist every 6 months for professional cleaning and polishing of your veneers.
Quit smoking — tobacco smoke causes a persistent yellow-brown coating to form on the veneer surface.
How to Preserve the Natural Whiteness of Veneers
Maintaining veneer brightness is a comprehensive process. Gentle but thorough oral hygiene, the use of appropriate care products for teeth and veneers, and regular professional cleaning at least twice a year are crucial.
