When Should You Replace Old Dental Fillings?

Brandon, SD Dentists Explain the Signs to Watch For

If you’ve had a dental filling for several years, you might be wondering: “Do fillings last forever?”

The short answer is no. Even the best dental fillings eventually wear down and may need to be replaced to protect your tooth and overall oral health.

At Neighborhood Dental in Brandon, South Dakota, Dr. Andy Schuiteman and Dr. Mauri Heesch help patients monitor existing fillings and replace them before they lead to bigger problems.

How Long Do Dental Fillings Last?

Most modern tooth-colored (composite) fillings are designed to be durable and long-lasting.

With proper care, fillings can last:

• 5–10+ years on average
• Longer with excellent oral hygiene and routine dental visits

However, no filling is permanent, and over time, normal chewing, temperature changes, and wear can cause it to break down.

7 Signs It May Be Time to Replace Your Filling

If you’re unsure whether your filling needs attention, here are the most common warning signs:

1. Tooth Sensitivity

Sensitivity to hot, cold, or sweets may indicate the filling is no longer sealing the tooth properly.

2. Pain When Biting or Chewing

Discomfort under pressure could mean the filling has cracked or shifted.

3. Visible Cracks or Wear

Fillings can chip, crack, or flatten over time, especially on back teeth.

4. Darkening Around the Filling

Staining or discoloration near the edges may signal leakage or decay underneath.

5. Food Getting Stuck More Often

Changes in how your teeth fit together can indicate a worn or failing filling.

6. Rough or Uneven Edges

If your tongue notices it, your dental team should too; this can be an early sign of breakdown.

7. Recurrent Decay

Bacteria can sneak under older fillings, leading to new cavities beneath them.

Why Replacing Old Fillings Matters

Ignoring a failing filling can lead to:

• Larger cavities
• Tooth fractures
• Infection or abscess
• The need for a dental crown or root canal

Early replacement is simple. Waiting can make treatment more complex and costly.

The Benefits of Modern Tooth-Colored Fillings

At Neighborhood Dental Brandon, we use composite resin fillings, which offer significant advantages over older materials:

✔ Longevity

With proper care, results can last 5 years or longer

✔ Preservation of Your Natural Tooth

Composite fillings bond directly to enamel, meaning less drilling and more natural tooth structure preserved

✔ Reduced Sensitivity

Unlike metal fillings, composite resin does not expand and contract with temperature changes

✔ Affordable Care

Most dental insurance plans cover a portion of treatment, making fillings a cost-effective solution

✔ Natural Aesthetics

Tooth-colored fillings blend with your natural smile, so you often can’t tell which tooth was treated

How Dentists Check Your Fillings

During your routine dental exam, your Dr. Schuiteman or Dr. Heesch will:

• Visually inspect your fillings
• Check for cracks, wear, or gaps
• Use digital X-rays to detect hidden decay
• Evaluate your bite and pressure points

This proactive approach helps catch issues before you feel symptoms.

Can Old Metal Fillings Be Replaced?

Yes, and many patients choose to replace older silver (amalgam) fillings with modern tooth-colored options for:

• Improved appearance
• Reduced risk of cracks
• Better bonding and protection

Your dentist can help determine if replacement is recommended or optional.

When Should You Schedule an Evaluation?

You should schedule a visit if:

• It’s been 5+ years since your last filling check
• You’re experiencing any sensitivity or discomfort
• You notice visible changes in your teeth
• You want to upgrade older fillings for aesthetics or comfort
