If you’ve ever sat in a dental chair and heard the words, “Looks like you’ve got a cavity,” you’re not alone. It’s one of the most common phrases dentists say, and thankfully, fixing a cavity is pretty straightforward—thanks to fillings.

But while fillings may seem like a routine part of dental care, not all fillings are created equal. And let’s be honest, most of us don’t ask too many questions when we’re numb and just want to get it over with. But choosing the right type of filling can make a difference in everything from comfort to durability to cost.

At Dental Specialists of Riverside, we’re all about making sure your smile not only looks great but lasts.

What are the different types of dental fillings, and how do they compare?

There are five main types of dental fillings used today: composite, amalgam, gold, ceramic, and glass ionomer. Each one has its strengths, trade-offs, and ideal uses depending on where the cavity is located and what your dental goals are.

Let’s break them down:

1. Composite Fillings (Tooth-Colored Fillings)

These are the go-to for most dentists and patients. Made from a resin that matches your tooth color, composite fillings are ideal for front teeth or any visible areas. They bond directly to your tooth, which helps preserve more of your natural structure.

• Pros: Natural look, strong bond, versatile.

• Cons: Slightly less durable than metal, can stain over time like natural teeth.

• Best for: Small to mid-sized cavities in visible areas.

2. Amalgam Fillings (Silver Fillings)

Amalgam fillings have been around for over 150 years and are made from a mix of metals, including silver, mercury, tin, and copper. They’re known for their durability.

• Pros: Strong, long-lasting, cost-effective.

• Cons: Not tooth-colored, may expand and contract over time.

• Best for: Back molars and areas under heavy chewing pressure.

3. Gold Fillings

Gold fillings are less common nowadays, but still a solid (literally) option. They’re custom-made in a lab and then cemented into place.

• Pros: Extremely durable, biocompatible, doesn’t wear down easily.

• Cons: Expensive, visible, requires multiple visits.

• Best for: Patients who don’t mind the look and want a long-term solution.

4. Ceramic Fillings (Porcelain)

Ceramic fillings are usually made from porcelain and are also tooth-colored. These are typically fabricated in a lab.

• Pros: Stain-resistant, durable, aesthetically pleasing.

• Cons: Can be brittle, more expensive than composite.

• Best for: Larger restorations where aesthetics are a priority.

5. Glass Ionomer Fillings

This lesser-known option is made from a mix of acrylic and glass. It releases fluoride over time, which can help protect the tooth.

• Pros: Fluoride release, good for kids, gentle on the tooth.

• Cons: Not very durable, limited to low-stress areas.

• Best for: Baby teeth, root cavities, and non-chewing surfaces.

How do I know which filling type is best for me?

This isn’t a one-size-fits-all decision, and the right choice depends on a few key factors:

• Location of the cavity: Fillings for back molars need to be tougher than those for your front teeth.

• Size of the cavity: Bigger cavities may need stronger materials like gold or ceramic.

• Your bite pressure: If you tend to grind your teeth or have a strong bite, you’ll need something that can take the heat.

• Aesthetics: If the filling will be visible when you talk or smile, tooth-colored options are usually preferred.

• Budget and insurance: Composite is often covered, but gold and ceramic may come with a higher out-of-pocket cost.

Your dentist will walk you through the options based on your unique case. Sometimes, it’s a quick decision—like when a tiny cavity pops up during a routine cleaning. Other times, like after a larger tooth fracture or root canal, you’ll discuss more extensive restoration options that might involve inlays, onlays, or crowns.

Do fillings hurt, and how long do they last?

Great question. First off, no—getting a filling shouldn’t hurt. Your dentist will numb the area with a local anesthetic, and you’ll likely feel some pressure, but no sharp pain. If you do, speak up. We're not trying to win any awards for stoicism here.

After the numbness wears off, some people experience mild sensitivity to hot or cold foods. This usually fades within a few days, but if it doesn’t, or if you feel like your bite is off, let your dentist know. A quick adjustment can save you from a lot of discomfort.

As for how long fillings last:

• Amalgam: Around 10–15 years (sometimes longer)

• Composite: 5–10 years

• Gold: 15–30 years (yes, really)

• Ceramic: 10–15 years

• Glass Ionomer: 5 years or less

These timeframes can vary based on your oral hygiene, diet, and whether you grind your teeth at night.

Can I prevent cavities and avoid fillings altogether?

The short answer: yes, it’s possible. But real talk—it takes commitment. And even then, some people are just more prone to cavities because of their genetics, enamel thickness, or mouth bacteria.

Here are some realistic tips that actually help:

• Brush twice a day with fluoride toothpaste

• Floss daily (yes, it matters)

• Cut down on sugary snacks and drinks

• Drink water, especially if it’s fluoridated

• Schedule regular dental check-ups every six months

Catch cavities early, and they’ll be easier to treat. Sometimes, a small cavity can even be reversed with fluoride treatments before it needs a filling.

If it’s been a while since your last check-up, don’t worry—we’ve seen it all. And we promise, judgment-free dentistry is a thing here at Dental Specialists of Riverside.
