Why Tooth-Colored Fillings Are the Modern Standard
Gone are the days when a dark metal filling was your only option. Today's composite resin fillings bond directly to your tooth, creating a seamless repair that blends with your natural enamel. They're strong, durable, and designed to last — and they look like part of your smile.
Composite vs. Amalgam: What's the Difference?
Amalgam (silver) fillings have been used for over a century, but they come with drawbacks. They expand and contract with temperature changes, which can lead to cracks over time. They also require removing more healthy tooth structure to hold the metal in place.
Composite fillings, by contrast, bond directly to your tooth. This means your dentist preserves more of your natural tooth. They're also mercury-free and don't create the dark spots that silver fillings leave behind. For most patients, composite is the clear upgrade.
Are Composite Fillings Right for You?
Composite fillings work well for cavities in both front and back teeth. They're also used to repair chipped, cracked, or worn teeth. During your exam, Dr. Andrea Leal or one of our general dentists will evaluate the size and location of the decay and recommend the best approach. If the cavity is small to moderate, a composite filling is usually the ideal choice.

What to Expect During Your Filling Appointment
If you've never had a filling — or it's been a while — here's what a typical visit looks like.
Step-by-Step: From Exam to Finished Restoration
First, your dentist examines the tooth and takes a digital X-ray to see the full extent of the decay. After numbing the area, the decay is gently removed. The tooth is then cleaned, and the composite resin is applied in thin layers. Each layer is hardened with a special curing light. Finally, your dentist shapes and polishes the filling to match your bite and blend with your surrounding teeth. The whole process usually takes under an hour.
What Happens If a Cavity Goes Untreated?
A small cavity doesn't stay small. Left untreated, decay spreads deeper into the tooth, reaching the inner pulp where nerves and blood vessels live. At that point, a simple filling is no longer enough — you may need root canal therapy or, in severe cases, an extraction. Treating a cavity early with a filling is far more comfortable, affordable, and preserves more of your natural tooth.
Fillings vs. Inlays & Onlays: Which Do You Need?
For cavities that are too large for a standard filling but not severe enough for a crown, an inlay or onlay may be the better option. These custom-made restorations are fabricated in a dental lab and bonded to the tooth. While a filling is placed directly in your mouth in one visit, an inlay or onlay requires two appointments. Your dentist will help you decide which option fits your specific needs. Learn more about inlays and onlays.
