Keep reading to protect your teeth and maximize the longevity of your dental investment.

Kinds of Dental Fillings and Their Average Lifespan

Different materials last for different periods. The type of filling used during your appointment plays a big role in how long it holds up. Here’s a breakdown of the most common types:

1. Composite (Tooth-Colored Fillings)

• Matches your natural tooth color

• Great for visible front teeth

• Lifespan: Usually 5–7 years, but some last up to 10 years

2. Amalgam (Silver Fillings)

• Durable and strong

• Common for molars and areas under pressure

• Lifespan: Around 10–15 years

3. Gold Fillings

• Strongest and most long-lasting option

• Doesn’t corrode

• Lifespan: 15–30 years

4. Ceramic Fillings

• Made of porcelain

• Resistant to staining

• Lifespan: Up to 15 years with adequate care

Each type has its strengths. Your choice often depends on cost, location in your mouth, and your personal preference.

If you’re unsure which type you received, your dentist in Logan can help explain what’s in your mouth and what to expect from it.

What Affects the Longevity of Dental Fillings?

Several factors influence how long your fillings stay intact. Some are under your control, and others depend on the condition of your teeth.

Here are the main factors:

• Oral hygiene: Brushing and flossing protect both teeth and fillings

• Biting forces: Clenching or grinding wears fillings down faster

• Diet: Too many sugary snacks or acidic drinks cause decay

• Location of the filling: Back teeth take more chewing force

• Size of the filling: Larger fillings are more prone to damage

• Material used: Some are built for durability, others for appearance

Your habits and daily choices matter. Even the strongest material won’t last long without care.

Signs Your Dental Filling Might Need Replacement

It’s not always easy to tell when a filling has gone bad. Some signs are subtle. Others are impossible to miss.

Keep an eye out for these:

• Tooth sensitivity to hot, cold, or sweet foods

• Pain or discomfort when chewing

• Visible cracks or wear on the filling

• Discoloration around the edges

• A feeling of roughness with your tongue

• Food is getting stuck where it didn’t before

If you notice any of these, schedule an exam. You may need a new filling or another form of repair. Catching problems early prevents larger procedures later.

Tips to Extend the Life of Your Dental Fillings

You don’t have to leave it to chance. A few small habits can keep your fillings secure for years. Follow these simple steps:

• Brush your teeth two times everyday while using a soft-bristled toothbrush

• Floss gently once a day to remove debris between teeth

• Avoid chewing on too hard items like ice or pens

• Use a mouthguard if you grind your teeth at night

• Limit sugary and sticky foods that stick to fillings

• See your dentist regularly for clean-ups and checkups

These habits don’t just protect fillings—they help prevent new cavities.

If you’re looking for a tooth filling service near you, make sure the provider emphasizes long-term care and patient education.

When to Consider Replacing Fillings

Sometimes, fillings need to be replaced even if they don’t show obvious signs of damage. Over time, the edges wear down, and bacteria can sneak underneath.

Common reasons for replacement:

• Leakage around the filling, leading to new decay

• Fractured tooth or filling from biting something hard

• Poor fit or a filling that has shifted

• Wear and tear from years of use

Your dentist may recommend replacement during a routine visit, even if you haven’t noticed anything wrong. That’s a good thing—it means they’ve caught it early.

If your filling is older than 10 years, it’s smart to have it checked more often.

The Dental Fillings Procedure: What to Expect

For those curious or nervous about getting a new one, here’s what usually happens during a dental filling procedure:

• First, the dentist checks and examines the tooth and takes an X-ray if needed

• Then they numb the area to keep you comfortable

• They extract the decayed portion of the tooth

• Finally, the chosen material is placed and shaped to fit your bite

Most fillings take under an hour. You can go back to your routine shortly after, though your mouth may feel numb for a little while.

The procedure itself is simple, but long-term care is what keeps your mouth healthy.
