Dental veneers are designed to last for many years, but they aren’t permanent. Over time, even the best-made veneers can start to show signs of wear or become less effective as your natural teeth and gums change. Knowing when it might be time to replace them isn’t always clear-cut, but there are certain signs and practical factors that can help guide you.
In this blog, we’ll go through how to recognise when veneers might need to be replaced, what affects their lifespan, and what to expect when replacement becomes necessary.
How long do dental veneers usually last?
Porcelain veneers are generally made to be long-lasting. On average, they can last anywhere from ten to fifteen years, sometimes longer with good oral care. Composite veneers usually have a shorter lifespan, often around five to seven years before they start to wear down. These estimates can vary depending on factors like how well you maintain your oral hygiene, your bite alignment, and even the materials used.
The way veneers are bonded to your natural teeth also influences how long they last. The adhesive must create a strong and stable bond between the veneer and the tooth surface. Over time, this bond can weaken due to daily wear, exposure to acidic foods or drinks, or teeth grinding. Once the bond starts to fail, the veneer may loosen or develop small gaps that allow bacteria to get underneath.
What are the signs that veneers need replacing?
The most obvious indicator that veneers may need replacing is visible damage. Small cracks, chips, or surface wear can make them less effective. Even minor damage can affect how they function, as veneers rely on an intact structure to remain securely attached to the tooth beneath.
Discolouration is another common sign. While porcelain veneers are stain-resistant, the cement used to bond them or the edges near the gumline can darken over time. If your veneers start to appear dull or yellowed compared to how they looked when first fitted, replacement might be worth considering.
A change in fit or comfort can also indicate that replacement is needed. If your bite starts to feel different, or if there’s a rough edge catching on your tongue, it could suggest that a veneer has loosened slightly or that the underlying tooth has shifted. In some cases, gum recession around the edges of veneers exposes the natural tooth underneath, which can alter the appearance and leave those areas vulnerable to decay.
How does oral health affect veneer longevity?
Your gums and the teeth underneath the veneers play a big role in how long the veneers last. If you develop gum disease or tooth decay, it can compromise the base that supports them. Veneers can only sit securely on healthy tooth structure, so maintaining regular brushing, flossing, and check-ups will always make a difference.
When gum tissue begins to recede, the edges of veneers can start to become exposed. This doesn’t just affect appearance, it can also allow bacteria to enter, increasing the risk of decay at the margin where the veneer meets the natural tooth. Regular dental cleaning can help to prevent this and ensure that the veneers remain properly sealed. Grinding or clenching your teeth (a condition known as bruxism) can also shorten their lifespan. The constant pressure can cause micro-fractures in the porcelain or loosen the bond between the veneer and the tooth. Wearing a night guard, if recommended, can reduce this risk and protect dental veneers from unnecessary strain.
Can dental veneers be repaired instead of replaced?
In some cases, a damaged veneer can be repaired rather than replaced entirely, but this depends on the extent of the damage and the material used. Small chips or rough edges in composite veneers can often be polished or patched by adding more resin. Porcelain veneers, however, are less easily repaired due to their brittleness and smooth surface, which doesn’t bond well to new material.
If the damage is limited to a single veneer, a replacement might only be needed for that one tooth. However, if veneers were originally placed to create a uniform appearance across several teeth, replacing just one might not match perfectly with the rest. Your dentist might therefore recommend replacing a set to maintain consistency in shape and shade.
What happens when veneers are replaced?
Replacing veneers involves carefully removing the existing veneer and preparing the tooth again. The old bonding material is cleaned off, and the tooth surface may be slightly reshaped before the new veneer is fitted. Since the natural tooth underneath has already been trimmed from the first procedure, it’s important that replacement veneers are placed accurately and securely to avoid over-reducing the enamel.
Your dentist will take impressions or digital scans of your teeth to create new dental veneers that fit precisely. Once they are ready, the new veneers are bonded onto the teeth using a specialised dental adhesive. The process is typically quicker than the first time veneers were fitted, as less preparation is needed.
It’s common to experience slight sensitivity around the treated teeth after replacement, especially if small adjustments were made during removal. This usually settles within a few days as your gums and teeth adapt to the new veneers.
What should you discuss with your dentist before replacing veneers?
Before going ahead with replacement, it’s worth discussing your current oral health and whether any changes have occurred since your veneers were first placed. Your dentist may take new X-rays or scans to check the structure of the teeth underneath.
You can also use this time to discuss any adjustments you’d like made, such as the shade or shape of the veneers. Some patients choose to make small refinements during replacement, especially if the original veneers were fitted many years ago and dental materials have since improved.
