Dental Fillings in Springfield, OR

A dental filling is the most common way to repair a tooth. When decay creates a cavity or a small crack starts to spread, a filling stops the damage and restores the tooth's strength. At Two Rivers Dental Group in Springfield, OR, Dr. Matthew Collins uses tooth-colored composite that bonds directly to your tooth and matches your natural shade, so your fillings stay invisible. Most cases are completely finished in a single visit and most patients walk out the same day they walked in.

Six Signs It's Time to Come In

Cavities don't always hurt right away, which is why routine exams catch most of them early. Once symptoms appear, here's what most patients describe.

Sensitivity to Cold or Sweets

A sharp twinge when eating ice cream, drinking cold water, or biting into something sweet.

A Visible Dark Spot

A small dark or stained area on a tooth surface that wasn't there before.

A Hole You Can Feel

A noticeable pit, divot, or rough patch your tongue keeps finding on a tooth.

Pain When Chewing

Discomfort when biting down on a specific side, especially with hard or sticky food.

Lingering Toothache

A dull ache that comes and goes or sharpens when you're tired or chewing on that side.

Food Catches Often

Floss or food keeps getting stuck in the same spot between two teeth.

Notice any of these? Don't wait. Small cavities are easy and affordable to fix. Untreated cavities grow and may eventually need a crown or root canal. Call (541) 746-9552 to schedule.

Why We Use Modern Composite

Most dental practices have moved away from traditional silver amalgam fillings. We use tooth-colored composite as our default. Here's why it matters.

What We Use

Tooth-Colored Composite

A bonded resin material that matches your natural tooth color and chemically attaches to the tooth structure. Modern composites have come a long way in strength and durability.

  • Invisible in your smile, even up close
  • Bonds directly to the tooth structure
  • Requires less tooth removal than amalgam
  • Mercury-free and metal-free
  • Strong enough for most chewing surfaces
  • Can be repaired or refreshed easily
What We Don't Use

Silver Amalgam

The classic silver-colored fillings used for over a century. They worked well structurally but came with downsides our patients no longer have to accept.

  • Visible silver-gray color in your smile
  • Doesn't bond, held in by mechanical shape
  • Requires removing more healthy tooth
  • Contains mercury (a small amount)
  • Expands and contracts over years
  • Often needs to be replaced after 10-15 years

Five Steps from Start to Finish

Most filling appointments take 30 to 60 minutes depending on the size and location of the cavity. Here's exactly what happens during your visit.

01

Numbing the Area

Local anesthesia is applied to the area around the tooth. We use a topical numbing gel first so the injection itself stays comfortable.

02

Removing the Decay

Dr. Collins gently removes the decayed portion of the tooth. Only the damaged tissue is taken out. Healthy tooth structure is preserved.

03

Cleaning & Conditioning

The cavity is cleaned and a mild conditioner is applied to help the composite bond securely to the tooth.

04

Placing the Composite

Tooth-colored composite is placed in thin layers and hardened with a curing light. Dr. Collins shapes the material to match the original tooth contour.

05

Polish & Bite Check

The filling is polished to mimic natural enamel. Dr. Collins checks your bite to make sure it feels right when you chew. You leave the same day.

Old Fillings

When Existing Fillings Need to Be Replaced

If you have older silver fillings or composite fillings from years ago, they don't last forever. Most fillings need to be replaced at some point, and catching them before they fail saves you a much bigger restoration down the road.

Dr. Collins reviews your existing fillings at every routine exam. We only recommend replacement when there's a real reason. No upselling for the sake of it.

Watch for These Warning Signs
  • The filling looks chipped, cracked, or worn
  • You feel sensitivity at that specific tooth
  • Food keeps getting stuck near the filling
  • You notice a dark line or stain at the edge
  • The filling is more than 10-15 years old
  • You're updating your smile cosmetically

Dental Filling FAQ

Modern composite fillings typically last 7 to 10 years with proper care. Some last longer, depending on the size of the filling, where it's located, and your bite. Daily brushing, daily flossing, and routine cleanings all extend the life of every filling.
No. Local anesthesia keeps the procedure comfortable. We apply a topical numbing gel before any injection so even the numbing process stays gentle. Most patients feel only mild pressure during the actual filling. Some sensitivity to hot or cold for a few days afterward is normal.
No. We use tooth-colored composite that's matched to your natural shade. Most patients are surprised that even up close, the filling blends right in. Old silver amalgam fillings can look like dark spots, but modern composite stays invisible.
Yes. Many patients choose to replace older silver fillings with tooth-colored composite for cosmetic reasons or because the old fillings are showing wear. Dr. Collins reviews each filling at your routine exam and recommends replacement only when it makes sense, not just for the sake of swapping them.
Right away with composite fillings. The composite is fully hardened by the curing light during the procedure, so there's no waiting period. We do recommend waiting until the numbness wears off, usually 1 to 2 hours, so you don't accidentally bite your cheek or tongue.
Most dental insurance plans cover a portion of dental fillings since they restore tooth function. Coverage varies based on whether the filling is on a front or back tooth, and how much your specific plan covers. Two Rivers Dental Group accepts most major plans and our team will help you understand exactly what's covered. Visit our patient resources page for more.
