White fillings are a popular choice for treating cavities because they blend with natural teeth, making it look like nothing ever happened. They’re durable, aesthetically pleasing, and a great alternative to silver fillings.

But what happens when that once almost invisible filling starts looking different? Maybe it’s turning yellow, brown, or even darker than the rest of your tooth. Is this normal? And more importantly, does it mean you need to replace your white filling in Kennet Square? Let’s break it all down. 

Is It Normal for White Fillings to Change Color? 

Yes, some discoloration in white fillings is normal over time. Everyday exposure to food, drinks, and natural wear can cause mild yellowing or slight darkening. However, if your filling turns drastically darker, develops black or gray spots, or looks uneven compared to the rest of your tooth, it may indicate a problem.

Discoloration can be external or internal. If you notice a sudden color change, it’s best to have your dentist check it out to determine if it’s just staining or something more serious. 

Why Do White Fillings Change Color? 

1. Staining from Food and Drinks

Just like natural teeth, white fillings can absorb stains from highly pigmented foods and beverages. Common culprits include: 

• Coffee, Tea, and Red Wine: These drinks contain tannins that darken fillings over time. 

• Tomato-Based Sauces and Curry: Their strong pigments can cling to dental materials. 

• Dark Berries: Blueberries, blackberries, and pomegranates contribute to staining. 

• Smoking or Tobacco Use: Nicotine and tar cause fillings to turn yellow or brown. 

2. Wear and Roughness Over Time

When a filling is brand new, it has a smooth, polished surface. However, as time goes on, chewing, brushing, and exposure to acidic foods can wear it down. A rougher surface makes the filling more porous, allowing stains to settle in faster. 

Additionally, older fillings may lose their luster, appearing dull, faded, or slightly darker than the surrounding teeth.

3. Decay Beneath the Filling

In some cases, a filling looks darker not because of external stains, but because of a cavity forming underneath. If a filling isn’t sealing properly or has started to wear down, bacteria can sneak in and cause decay inside the tooth. 

Signs that decay may be the issue include: 

• A dark or gray shadow under the filling 

• Sensitivity or pain when eating or drinking 

• A loose or rough filling 

If this happens, the filling must be replaced to prevent further damage. 

What Can You Do About a Discolored Filling? 

If your filling has changed color, here’s what you can do: 

• Professional Polishing: In some cases, a dentist can buff out surface stains and restore the original shade. 

• Filling Replacement: If discoloration is severe or caused by decay, replacing the filling is the best solution. 

• Upgrade to a Porcelain Restoration: For a more stain-resistant option, some patients choose to replace fillings with porcelain inlays or onlays. 

The right choice depends on the cause of the discoloration and the condition of the filling. Your dentist can help determine the best solution. 

Can You Whiten a Discolored Filling? 

Unfortunately, fillings do not respond to whitening treatments the same way natural teeth do. While you can whiten the surrounding enamel, the filling will stay the same color, which can lead to a noticeable mismatch.
