Dental fillings in Roanoke, Virginia, help repair cavities and small fractures so teeth stay strong and comfortable. At Star City Family Dentistry, patients can expect clear guidance on when a filling is needed, material choices, and how the appointment works from start to finish.
Dental Fillings Explained
A dental filling restores tooth structure lost to decay or minor damage. After removing softened, infected enamel and dentin, our dentist places a biocompatible material to seal the area. This stops the spread of decay, restores shape and function, and supports everyday chewing. Fillings are often recommended when a cavity is caught early, when a tooth has a small chip, or when an old filling needs replacement.
Why Consider Dental Fillings?
- Pain relief by removing decay and sealing sensitive areas.
- Tooth preservation by preventing a small cavity from growing.
- Stronger chewing by restoring natural contours and contact points.
- Improved appearance with tooth-colored options that blend in.
- Quick care that is usually completed in a single visit.
- Balanced cost compared with larger restorations like crowns.
Understanding Your Filling Options
Several materials are used for dental fillings, each with benefits depending on the tooth location, size of the cavity, and personal goals.
Composite (Tooth-Colored) Fillings
Composite resin bonds to tooth structure and can be closely matched to enamel color. It works well for front teeth and visible areas, and it is also common for small to moderate back-tooth cavities. Bonding can allow for conservative preparation, preserving more natural tooth.
Amalgam (Silver) Fillings
Amalgam is durable and has a long record of use, especially for molars under heavy biting forces. Color is the main trade-off. Many patients now prefer composite for a more natural look, but amalgam remains a reliable option for certain clinical situations.
Glass Ionomer and Ceramic Options
Glass ionomer can release fluoride and is sometimes used for non-chewing surfaces or for temporary restorations. Ceramic or porcelain inlays and onlays are lab-made options used when a cavity is too large for a standard filling but does not yet need a full crown.
How Dental Fillings Work
- Exam and imaging to confirm the cavity size and location.
- Numbing the tooth so treatment is comfortable.
- Removing decay and shaping the area for the filling.
- Placing the chosen material and curing if needed.
- Shaping and polishing for a smooth bite and natural feel.
Most appointments take about 30 to 60 minutes per tooth, depending on complexity. If decay is deep and the nerve is involved, additional treatment may be discussed.
What to Expect Before and After Treatment
Before your visit, eat a light meal and brush as usual. Tell the team about any medical conditions or sensitivities. During treatment, local anesthesia prevents pain. You may feel vibration or pressure while decay is removed, but you should not feel sharp sensation.
After treatment, numbness may last a few hours. Avoid chewing until feeling returns to prevent biting your cheek or tongue. Mild sensitivity to cold or chewing is common for a few days and often improves as the tooth settles. Use a soft toothbrush, fluoride toothpaste, and floss daily. Call if pain worsens, if the filling feels high, or if sensitivity lasts more than one to two weeks. Early attention prevents more complex procedures.
Longevity and Maintenance
With good home care and regular checkups, composite fillings often last 5 to 10 years, while amalgam and ceramic restorations may last 10 years or longer. Lifespan varies with cavity size, bite forces, clenching or grinding, and diet. To extend longevity, limit frequent snacking, reduce sugary drinks, wear a night guard if recommended, and keep up with professional cleanings.
When A Filling May Not Be Enough
If decay is extensive or a tooth has large cracks, a crown, inlay, or onlay may provide better strength. If decay reaches the pulp and causes infection, root canal therapy may be needed before final restoration. An exam helps determine the most conservative option that will still protect the tooth.
