If you have veneers or are considering them, it's helpful to know the signs of poorly fitted or low-quality veneers. This page outlines common signs of bad veneers, what to look out for, and your options if you encounter any issues.
Several veneer types are available. Understanding the differences can help you discuss options with your dentist.
Porcelain veneers: Thin porcelain shells bonded to the front of the teeth. Porcelain veneers require the teeth to be filed before placement — this preparation is irreversible. Porcelain veneers typically last 10 to 20 years depending on care.
Composite veneers: A thin layer of resin applied directly to the teeth and sculpted by the dentist. Less tooth preparation is required than with porcelain. Composite veneers typically last 5 to 7 years depending on care.
Several signs can indicate that veneers have not been properly fitted or are made from poor-quality materials.
Pain or discomfort: Correctly fitted veneers should feel comfortable. Persistent discomfort or pain when speaking, chewing, or biting may indicate the veneers are too thick, misaligned, or placed too close to the gum line, causing irritation or inflammation.
Unnatural appearance: Veneers that are the wrong shade, too large, too small, or appear flat and opaque can indicate poor-quality work or incorrect sizing. Well-made veneers should be proportionate and appropriately matched to the surrounding teeth.
Staining or discolouration: While veneers are generally more stain-resistant than natural teeth, poor-quality veneers can discolour. Brown lines, yellowing, or loss of whiteness can indicate material quality issues or inadequate care.
Gaps or margins: Gaps between the veneers and the tooth surface indicate poor fit. These gaps can trap food, increasing the risk of decay and gum disease.
Leakage at the gum line: If veneers are not properly sealed to the tooth, bacteria can grow beneath the veneer, causing decay and irritation. Sensitivity near the gum line and discolouration may indicate leakage.
Chipped or cracked veneers: Veneers can chip or crack due to incorrect placement, poor-quality materials, or teeth grinding. Damage occurring soon after placement may indicate a fitting issue. If you grind your teeth, a custom night guard can help protect both veneers and natural teeth.
Poor fit or misalignment: Veneers that appear crooked, misaligned, or do not follow the natural contour of the teeth can cause discomfort and may lead to long-term damage. Misaligned veneers can also contribute to temporomandibular joint (TMJ) disorders. Contact your dentist promptly if you are concerned about veneer alignment.
Gum swelling or recession: Poorly placed veneers can cause gum swelling, bleeding, or recession. Gum recession creates gaps where bacteria can accumulate, increasing the risk of gum disease.
If you notice any of these issues, contact your dentist. The following steps outline the typical process for addressing bad veneers.
Arrange a consultation so your dentist can evaluate your current veneers, identify the cause of the issues, and recommend a treatment plan. Expect scans or impressions to help the dentist assess the situation.
Composite veneers can sometimes be reshaped or adjusted. For porcelain veneers, and in most cases for composite veneers where adjustment is not sufficient, replacement is the recommended approach. Your dentist will remove the current veneers, take new impressions, and fabricate replacement veneers. Temporary veneers may be provided during this period.
When replacing veneers, discuss material options with your dentist. Different materials have different characteristics in terms of durability, appearance, and cost. Your dentist will recommend the most appropriate material based on your clinical situation.
Proper aftercare is essential for the longevity of replacement veneers. Brush and floss daily, attend regular dental check-ups, avoid biting hard objects, and if you grind your teeth, use a night guard. Your dentist will provide specific aftercare instructions.
All dental treatments carry risks. Risks of veneer treatment include tooth sensitivity during and after preparation; the irreversible removal of natural enamel (for porcelain veneers), meaning the teeth will always require veneers or another restoration; the possibility of veneers chipping, cracking, debonding, or failing over time; colour mismatch between veneers and natural teeth over time; the potential need for root canal treatment if the nerve is affected during preparation; and the need for eventual replacement, as veneers are not permanent.
Your dentist will discuss all risks specific to your case before any treatment.
