How long do tooth-colored fillings last?

Most composite fillings last 7 to 10 years, and many last well beyond that. Lifespan depends on the size of the filling, where it sits in your mouth, and habits like grinding or chewing ice. Large fillings on back molars take the most force, so they tend to wear faster than small ones on front teeth. We check every filling at your routine exams so we can catch wear before it leads to new decay.

Why is my tooth sensitive after a filling?

Mild sensitivity to cold or pressure is common for a few days to a couple of weeks, especially after a deeper filling. The nerve inside the tooth was close to the work area and needs time to settle. If the sensitivity gets worse instead of better, or if your bite feels high when you close your teeth together, call our office. A quick bite adjustment often solves the problem in a few minutes.

Should I replace my old silver fillings?

Not necessarily. The FDA considers amalgam fillings safe for most adults, and removing an intact filling means removing some healthy tooth structure along with it. Replacement makes sense when an old filling is cracked, leaking, or has decay around its edges, or when you'd simply like a more natural look. Dr. Bartz will examine each one and tell you honestly whether it needs attention.

Will my filling change color if I whiten my teeth?

No. Whitening gel lightens natural enamel, but it has no effect on composite resin. If you're planning to whiten, it's best to do it before getting a filling on a visible tooth so we can match the composite to your new shade. Existing fillings can be replaced afterward if they no longer blend in.

Does insurance cover tooth-colored fillings on back teeth?

Some plans do, but others pay only the amalgam rate for molars and leave you responsible for the difference. This is called a downgrade clause, and it's common in older or lower-cost plans. Our team can check your benefits before your appointment so you know your out-of-pocket cost ahead of time.

Natural-Looking Cavity Repair Built for Everyday Chewing

A cavity is a hole in the enamel created by acid-producing bacteria, and once it breaks through the surface, it can’t heal on its own. Left alone, decay keeps moving inward toward the softer dentin and eventually the nerve, which is when a simple repair turns into a root canal. A tooth-colored filling stops that progression early by removing the decay and sealing the tooth with composite resin shaded to match your enamel.

At KB Dental, Dr. Karina Bartz places composite fillings for patients from Heath, Rockwall, Forney, Rowlett, Sunnyvale, and Royse City. Most fillings are finished in a single visit, and the procedure itself usually takes less than an hour once the tooth is numb. To schedule an exam, call (972) 213-0063.

Why Patients Choose KB Dental for Cavity Treatment

Dr. Karina Bartz earned her DDS from New York University College of Dentistry and completed a one-year Advanced Education in General Dentistry (AEGD) residency at Lutheran Medical Center in Brooklyn, giving her postgraduate restorative training beyond dental school. She approaches every cavity with the same goal: remove only what’s damaged and keep as much of your natural tooth as possible.

We also want you to see what we see. Intraoral camera images and digital X-rays appear on screen during your exam, so you can look at the problem area yourself and understand why a filling is recommended or why a small spot can safely be monitored for now. Dr. Bartz lives right here in Heath, and she treats her patients like the neighbors they are.

What Is a Tooth-Colored Filling?

A tooth-colored filling is made from composite resin, a blend of plastic resin and fine glass or quartz particles. Dr. Bartz bonds it directly to the tooth with an adhesive, builds it up in thin layers, and hardens each layer with a curing light. Because the material is shade-matched and polished, the finished filling is difficult to tell apart from the enamel around it.

The bond itself is a big part of why composite is the standard choice today. Older silver amalgam fillings stay in place mechanically, so the dentist has to cut undercuts into healthy tooth structure to lock them in. Composite holds by adhesion, which means more of your natural tooth can be preserved.

Signs You May Need a Filling

Cavities don’t always announce themselves, but these are the changes patients notice most often:

Sensitivity to Sweets, Heat, or Cold: A quick zing when you drink something cold or eat something sugary often means decay has reached the dentin.
A Dark Spot or Visible Hole: Brown or black areas on the chewing surface, especially ones that catch floss or a fingernail, are worth having checked.
Food Catching Between Two Teeth: A cavity between teeth can open a gap where food packs in after every meal.
A Rough or Chipped Edge: If your tongue keeps finding a sharp spot, part of the tooth or an old filling may have broken.
No Symptoms at All: Early cavities are usually painless, which is why we rely on digital X-rays and intraoral camera images during routine dental exams.

What to Expect During Your Filling Appointment

A filling visit follows the same basic sequence from start to finish:

Diagnosis: Dr. Bartz confirms the size and location of the decay using digital X-rays and an intraoral camera, and you’ll see the images on screen.
Numbing: A local anesthetic numbs the tooth and surrounding gum. Nitrous oxide is available if you’d like help relaxing.
Removing the Decay: The softened, infected portion of the tooth is cleaned out, leaving only healthy structure behind.
Bonding and Layering: The tooth is prepared with an adhesive, and the composite is placed in layers and cured with a light.
Shaping and Polishing: The filling is sculpted to match your natural bite, checked with articulating paper, and polished smooth.

When a Filling Isn’t Enough

Fillings work best for small to moderate cavities. When decay or an old filling covers a large portion of the tooth, a big composite filling can flex under chewing pressure and crack the thin walls that remain. In that case, Dr. Bartz may recommend an inlay or onlay, which is fabricated as a single solid piece, or a dental crown when the tooth needs full coverage. You can compare all of these options on our restorative dentistry page.

Caring for Your New Fillings

Composite is fully hardened before you leave, so you can eat as soon as the numbness wears off. Waiting until feeling returns keeps you from accidentally biting your cheek or tongue. After that, a filled tooth needs the same care as the rest of your teeth: brushing twice a day, flossing daily, and regular cleanings so we can check the edges of each filling for wear or new decay.

How Much Do Tooth-Colored Fillings Cost?

In the United States, a composite filling typically costs about $150 to $300 per tooth, with a national average near $225. The price rises with the number of tooth surfaces involved, so a small filling on one surface costs less than one that wraps around two or three sides. Many dental insurance plans cover fillings as basic restorative care, often at 70% to 80% after the deductible.

If you don’t have insurance, the KB Dental Membership Plan includes 20% off fillings along with your annual exam and X-rays. We’ll give you an exact estimate before any treatment begins.
