Dental fillings in Los Angeles, CA: cavity repair explained

Dental fillings in Los Angeles, CA help restore teeth damaged by decay, wear, or minor fractures. At Leith K Shawaf DDS, patients in Los Angeles, California receive conservative treatment that seals out bacteria, restores chewing comfort, and maintains natural tooth structure. This page outlines what a dental filling is, the materials used, how the procedure works, and what to expect afterward.

Dental fillings explained

A dental filling is a restorative material placed into a tooth after decay is removed. The filling rebuilds the lost structure, restores function, and prevents further decay. Common options include composite resin (tooth-colored), amalgam (silver), glass ionomer, and indirect restorations like porcelain or gold inlays/onlays when damage is more extensive. Patients often search for “what is a dental filling,” “how does a dental filling work,” and “types of dental fillings” to understand which option fits their needs.

For many cavities, tooth-colored composite is preferred because it bonds to enamel, blends with your smile, and allows a conservative approach. Amalgam remains durable for areas that bear heavy chewing forces. Glass ionomer can release fluoride, which may help in non-load-bearing areas. Indirect restorations are considered when a simple filling is not strong enough.

Why consider a dental filling?

• Stops decay progression and protects the remaining tooth.
• Relieves sensitivity and restores comfortable chewing.
• Preserves more natural tooth structure compared with crowns.
• Offers aesthetic results with tooth-colored materials.
• Supports long-term oral health when paired with good home care.

How the filling process works

The steps are straightforward and designed for comfort. Here is a typical sequence for cavity treatment.

• Exam and diagnosis: The tooth is evaluated with visual checks and X-rays to locate decay and assess depth.
• Numbing: Local anesthetic is used so the procedure feels comfortable. Mild pressure or vibration may be felt but not pain.
• Decay removal: The softened, infected portion of the tooth is carefully removed while preserving healthy structure.
• Tooth preparation: The area is cleaned and shaped. Isolation helps keep the site dry for best adhesion.
• Material placement: For composite, layers of resin are applied and light-cured. For amalgam, the material is packed and shaped.
• Shaping and bite check: The filling is trimmed, smoothed, and polished. The bite is adjusted to avoid high spots.

Your visit and aftercare

Numbness usually lasts a few hours. Composite fillings can be chewed on right away once numbness wears off, while amalgam may require waiting several hours before heavy chewing. It is common to notice mild temperature sensitivity for a few days as the tooth settles.

Good aftercare extends the life of your restoration. Brush twice daily with a fluoride toothpaste, clean between teeth, and limit frequent sugary snacks or drinks. Consider fluoride rinses if recommended. Schedule routine checkups so small issues are addressed early. If a filling feels high, cracks, or becomes sensitive to biting, contact the office promptly.

Longevity varies by material, tooth location, bite forces, and home care. Many composite and amalgam fillings last several years or longer with proper hygiene and regular maintenance. Indirect options like porcelain inlays or onlays may be suggested when extra strength or coverage is needed. Patients often ask “how long do fillings last,” and the answer depends on habits, grinding or clenching, and consistent professional care.

Filling material options

• Composite resin: Tooth-colored, bonds to enamel, strong and aesthetic for front and back teeth.
• Amalgam: Time-tested and durable, useful in areas under heavy chewing stress.
• Glass ionomer: Releases fluoride, often used in non-chewing zones or for certain root-surface lesions.
• Porcelain or gold inlay/onlay: Lab-made restorations for larger cavities when a simple filling may not suffice.

Material selection is individualized and considers cavity size, location, appearance, cost, and personal preferences. Discuss options at Leith K Shawaf DDS to choose the right approach for your tooth.
