Tooth-Colored Dental Fillings in Johnson City, TN

Composite Resin Restorations Dr. John Nauss, DMD ★★★★★ 5.0 on Google
Mercury-Free Composite Restorations

Repair cavities and restore tooth strength with seamless, tooth-colored composite resin.

When tooth decay strikes, prompt treatment prevents bacterial infection from spreading deeper toward the nerve of the tooth.

At Apex Dentistry & Implants, we exclusively use modern tooth-colored composite resin fillings. Unlike old-fashioned dark silver amalgam fillings that expand and cause micro-cracks over time, composite resin chemically bonds directly to your natural enamel.

This adhesive bonding reinforces the remaining tooth structure, requires less removal of healthy natural tooth, and matches the precise shade of your smile for invisible repairs.

Advantages of Composite Dental Fillings

A conservative, durable, and highly aesthetic solution for treating tooth decay.

  • 100% Metal-Free and Mercury-Free: Safe, biocompatible resin formulation that eliminates dark metallic discoloration.
  • Direct Enamel Bonding: Chemically adheres to natural tooth structure, restoring up to 90% of original tooth strength.
  • Conservative Tooth Preparation: Preserves significantly more healthy natural enamel than traditional amalgam cavity preparations.
  • Seamless Color Match: Custom shade-matched to blend invisibly with your surrounding natural dentition.

The Composite Filling Procedure

Dr. Nauss gently numbs the area using comfortable local anesthesia. The decayed enamel is carefully cleared, and the tooth is sanitized and conditioned with a gentle bonding agent.

The shade-matched composite resin is applied in delicate layers and cured instantly with an LED light. Dr. Nauss precisely shapes the chewing anatomy, verifies your bite alignment, and polishes the restoration smooth.

Immediate Eating and Aftercare

Because composite fillings are fully hardened before you leave our office, you can eat immediately once your local numbness wears off. Maintain regular brushing and flossing to protect the margins from recurrent decay.

Common Questions

Dental Fillings FAQ.

Frequently asked questions regarding composite fillings, old silver replacement, and aftercare.

How long does a filling appointment take?

Most fillings are done in a single visit, usually in under an hour depending on the size and number of cavities.

Can I replace my old dark silver amalgam fillings with composite?

Yes. Many patients choose to replace old amalgam fillings that are leaking, fractured, or cosmetically unappealing with modern tooth-colored composite resins.

Will I feel any pain during a filling appointment?

No. We use local anesthesia to numb the tooth and surrounding gums, and nitrous oxide is available if you'd like help relaxing.

Can I eat immediately after getting a composite filling?

Composite fillings are fully cured when you leave our office. We simply recommend waiting until your numbness wears off to prevent accidentally biting your lip or cheek.

Is it normal to have tooth sensitivity after a new filling?

Mild sensitivity to hot and cold can occur for a few days after deep cavity treatment as the nerve settles. This typically resolves within 1 to 2 weeks.

Does dental insurance cover tooth-colored fillings?

Many plans cover fillings. We're in network with Delta Dental Premier only, we'll help you file out-of-network claims with other plans, and we offer a membership plan for patients without insurance.
