Cavities Happen — Getting Them Fixed Shouldn't Be a Big Deal
Tooth-Colored Fillings in Decatur, TX: Natural-Looking Cavity Treatment
A filling is one of the most common procedures in dentistry — and one of the quickest. When decay creates a cavity in your tooth, a filling removes the damaged portion and restores the tooth's shape and function. At Christian Family Dentistry, we use tooth-colored composite resin that's custom-shaded to match your natural teeth — so the repair blends in and nobody can tell it's there.

Composite fillings bond directly to the tooth — preserving more healthy structure than traditional amalgam.
Because composite resin adheres to enamel, less drilling is required to hold the filling in place. That means more of your natural tooth stays intact.
How a Filling Appointment Works, Step by Step
A filling is one of the most straightforward procedures in dentistry. Most appointments take 30 to 60 minutes depending on the size and location of the cavity. Here's what happens from start to finish.
Numbing
Local anesthesia numbs the tooth and surrounding gum tissue. You shouldn't feel any pain during the procedure.
Decay Removal
The decayed portion of the tooth is carefully removed, leaving only clean, healthy tooth structure behind.
Layering
Composite resin is applied in thin layers, each one custom-shaded to match your natural tooth color.
Curing
A special blue light hardens each layer in seconds, bonding the material directly to the enamel and dentin.
Shaping
The filling is shaped and polished to match your bite. You leave with a restoration that looks and feels like your own tooth.
Why We Prefer Tooth-Colored Composite Fillings
For decades, silver amalgam was the standard filling material. It's durable and cost-effective — and it still has a place in certain situations. But composite resin has become the preferred choice at most modern practices, including ours, for several important reasons.
- Invisible repair: Composite is custom-shaded to match your tooth — the filling blends in completely
- Bonds to the tooth: Composite adheres directly to enamel, which means less healthy tooth needs to be removed to hold the filling in place
- No metal, no mercury: Composite is a mixture of plastic resin and fine glass particles — no metallic components
- Less sensitivity: Metal fillings expand and contract with temperature changes, which can cause microcracks over time. Composite doesn't
- Versatile: Used for cavities, chips, worn edges, and minor cosmetic repairs in a single appointment
Amalgam still offers advantages for very large cavities on back molars where durability under heavy chewing pressure is the top priority. Dr. Nwokorie will recommend the best material for your specific situation.
What Tooth-Colored Fillings Can Fix
Composite resin is one of the most versatile materials in dentistry. Beyond standard cavities, it's used for a range of minor repairs that restore both function and appearance.
Cavities (Tooth Decay)
The primary use for fillings. When decay creates a hole in the enamel, the damaged portion is removed and filled with composite resin to restore the tooth's shape, strength, and seal against bacteria.
Chipped or Worn Teeth
Minor chips from biting something hard, or worn edges from grinding or acid erosion, can be rebuilt with composite bonding — often in a single visit without any numbing needed. See our cosmetic dentistry options →
Replacing Old Amalgam Fillings
When an older silver filling cracks, loosens, or develops decay around its edges, it can be replaced with a tooth-colored composite. The result is a more natural appearance and a fresh seal against bacteria.
Small Gaps or Cosmetic Imperfections
Minor gaps between teeth, surface irregularities, or small areas of discoloration can be addressed with composite bonding — a conservative, same-day cosmetic fix that doesn't require a veneer or crown.
Tooth Sensitivity After a Filling: What's Normal, What's Not
It's common to feel mild sensitivity in the days following a new filling — especially to cold, heat, or pressure. The drilling and cleaning process temporarily irritates the nerve inside the tooth, and it needs a little time to settle.
For most patients, sensitivity peaks in the first 48 hours and fades steadily over one to two weeks. Deeper fillings may take a bit longer. As long as it's improving day by day, that's normal healing.
- Normal: Brief twinges with cold or hot that fade within seconds
- Normal: Mild soreness when biting that gets better over a few days
- Call us: Pain that gets worse instead of better after the first few days
- Call us: Throbbing pain, especially at night
- Call us: Swelling, fever, or a bad taste near the tooth
- Quick fix: Pain only when biting down — often means the filling is slightly too high and needs a quick adjustment
When a Filling Isn't Enough — and a Crown Is the Better Call
A filling works well when the cavity is small to moderate and enough healthy tooth structure remains to support the restoration. But when the damage is more extensive — more than about half the chewing surface, a deep crack, or a tooth that's already been filled multiple times — a filling can't provide the structural support the tooth needs.
In those cases, a dental crown covers and reinforces the entire tooth, preventing it from splitting under chewing pressure. Dr. Nwokorie uses digital x-rays and intraoral imaging to evaluate the tooth and will explain exactly why he's recommending one option over the other — you'll see the same images he's looking at and understand the reasoning before any work begins.
If a crown is needed, our CEREC system can design, mill, and place a permanent porcelain crown in a single visit — no temporary, no second appointment.
How Long Do Fillings Last — and How to Make Them Last Longer
No filling lasts forever, but with good care, a composite filling can serve you well for many years. Here's what affects how long your filling lasts and what you can do to maximize its lifespan.
5 to 10+ years
Tooth-colored composite fillings typically last 5 to 10 years with good oral hygiene. Smaller fillings on low-stress teeth often last longer. Heavy grinders may wear through them faster.
10 to 15+ years
Amalgam fillings are exceptionally durable, especially on back molars. They handle heavy chewing forces well. The tradeoff is appearance — they're silver-colored and darken over time.
What helps
Brush twice daily, floss daily, attend regular cleanings every six months, and avoid chewing ice or hard candy. If you grind your teeth, a nightguard protects both fillings and natural enamel.
What a Filling Costs — and What Insurance Typically Covers
The cost of a filling depends on the size of the cavity, the material used, and the location of the tooth. Composite fillings require more time and technique to place than amalgam, which is reflected in the cost — but most patients find the aesthetic result worth it.
Most dental insurance plans cover fillings as a basic restorative procedure, typically at a high percentage. Some plans cover composite at the same rate as amalgam; others cover composite fully for front teeth and at the amalgam rate for back teeth, with the patient paying the difference. We verify your benefits before your visit and walk you through the numbers.
For patients without insurance, we accept CareCredit financing and provide a clear cost estimate before any work begins. A filling caught early is one of the most affordable procedures in dentistry — waiting until the cavity grows larger always costs more.
Think you might have a cavity?
Don't wait for it to hurt. Most cavities are painless until they're deep enough to reach the nerve — by which point you may need a root canal instead of a simple filling. A quick exam catches it early.
(940) 304-0205Questions Patients Ask About Fillings
Are tooth-colored fillings better than silver amalgam?
Each has strengths. Composite fillings offer a natural appearance, bond directly to the tooth (preserving more healthy structure), and don't contain metal. Amalgam is more durable under heavy chewing forces and may be recommended for large cavities on back molars. Dr. Nwokorie will recommend the best material for your specific tooth and situation.
Does getting a filling hurt?
No. The tooth and surrounding area are numbed with local anesthesia before any work begins — you shouldn't feel pain during the procedure. Some patients feel brief pressure, but that's it. If you're anxious about dental work, we offer nitrous oxide sedation to take the edge off.
How long do composite fillings last?
Composite fillings typically last 5 to 10 years or longer with good oral hygiene and regular dental visits. Smaller fillings on lower-stress teeth often last well beyond that. The biggest factors affecting lifespan are oral hygiene habits, teeth grinding, and the size of the original cavity.
Why does my tooth hurt after a filling?
Mild sensitivity to cold, heat, or pressure is common and usually fades within a few days to two weeks. The drilling process temporarily irritates the nerve. If the pain gets worse instead of better, if it throbs, or if you only feel it when biting down, call us — these may indicate a high bite that needs adjustment or, less commonly, an issue with the nerve. Read our full post-filling sensitivity guide →
Can you replace a silver filling with a white one?
Yes. When an old amalgam filling cracks, loosens, or has decay forming around it, it can be replaced with a tooth-colored composite. We don't recommend replacing intact, healthy amalgam fillings purely for cosmetic reasons — but when a replacement is needed, composite is typically the preferred material.
Do tooth-colored fillings stain?
Over time, composite resin can pick up surface staining from coffee, tea, red wine, and tobacco — similar to natural teeth. Regular brushing and professional cleanings help keep the color consistent. If a filling becomes noticeably stained, it can be polished or replaced.
How do I know if I have a cavity?
Early cavities often have no symptoms at all — they're caught during routine exams and x-rays. As a cavity grows, you might notice sensitivity to sweets, cold, or hot temperatures, visible dark spots or holes in the tooth, or food getting caught in the same spot repeatedly. The earlier a cavity is found, the smaller and simpler the filling.
What happens if I ignore a cavity?
A cavity will never heal on its own — it only gets larger. Left untreated, the decay eventually reaches the nerve inside the tooth, causing severe pain and infection. At that point, a simple filling is no longer an option — you'll need a root canal and a crown to save the tooth, or an extraction if the damage is too far gone. Catching it early saves time, money, and discomfort.
Can children get tooth-colored fillings?
Yes. Composite fillings are appropriate for both children and adults. We treat cavities in baby teeth too — untreated decay in baby teeth can cause pain, infection, and crowding problems for the permanent teeth developing behind them. Learn about our children's dental care →
