Is this right for you?

Signs you may need a filling

  • Sensitivity to cold or sweets
  • A rough edge you can feel with your tongue
  • Food catching between teeth
  • An old filling that has chipped, stained, or worn
  • A cavity found on X-rays, even with no symptoms

Sometimes there are no symptoms at all, which is why cleanings and exams matter.

In plain language

What is a tooth-colored filling?

A cavity starts when bacteria wear through the outer enamel. At first it may not hurt, which is why routine exams and X-rays matter.

A tooth-colored (composite) filling repairs it: we remove only the damaged portion and rebuild the tooth with composite resin that bonds to the structure underneath and matches your enamel. Because composite bonds to the tooth, more healthy structure stays than with older metal fillings.

Your visit, step by step

What a filling visit is like

  1. 1

    Exam and imaging

    A careful exam, with digital imaging when needed, shows the size and location of the decay.
  2. 2

    Gentle numbing

    We numb the tooth thoroughly and isolate it to keep the area dry. Sensitive or anxious? Tell us, and we’ll work at a pace that keeps you relaxed.
  3. 3

    Remove decay, rebuild in layers

    We remove only the softened, decayed enamel, then rebuild the tooth in small layers, curing each one for a strong bond.
  4. 4

    Bite check and polish

    We refine your bite and polish the filling so it feels smooth when you chew. Most appointments are quick.

Aftercare and prevention

You can eat normally once numbness wears off; avoid very sticky foods on the first day. Mild sensitivity can occur for a short time, and we’ll review bite comfort so the tooth feels normal quickly.

To prevent future cavities, brush twice daily, floss, and keep a steady schedule of professional cleanings.

Comfort, start to finish

  • Thorough, gentle numbing

    Most patients feel only pressure, not pain.

  • Conservative removal

    Only the decayed part comes out; healthy structure stays.

  • Shade-matched

    Composite is matched to your enamel so it blends in.

  • Bite adjusted for comfort

    We refine and polish until your bite feels smooth.

Options

Our approach to tooth-colored fillings

We shape and polish each filling so your bite feels comfortable and smooth, and we’ll tell you honestly when a filling isn’t enough.

  • What we use

    Tooth-colored composite

    Modern composite matches the shade of your tooth and supports natural chewing forces.
    • Bonds to enamel, so more healthy tooth stays
    • Shaded to blend in
    • Shaped and polished for a smooth bite
  • Repair or replace

    Replacing old fillings

    Older fillings, including silver ones, can be repaired or replaced if they weaken, leak, or no longer match your smile.

  • Larger damage

    When a crown is safer

    If decay spreads too far, a filling may not be strong enough, and a crown becomes the safer option.

Cost, insurance & payment

Filling cost and insurance

Earlier treatment is simpler and more affordable: a small filling today can avoid a crown or root canal later. We check your PPO benefits first.

What affects your cost

  • The size of the cavity and how many surfaces it involves
  • How many teeth need fillings
  • Whether X-rays are needed first
  • Your plan’s benefits for basic care
  • Have PPO insurance?

    We’re out-of-network, but most PPO plans still pay a share of your care here. Many plans cover fillings as basic care. Send us your plan and we’ll check your benefits and explain your portion before treatment.

    Ask about our in-house dental plan, which offers savings on preventive care and treatment.

Questions

Cavity filling FAQs

Comfort, lifespan, and what happens if you wait.

Do you use tooth‑colored fillings?

Yes. We primarily use composite fillings that blend naturally with your enamel and bond securely to the tooth.

How long do fillings last?

Most composite fillings last 7–12 years with good home care. Their lifespan depends on bite forces, tooth location, and diet.

Will a filling hurt?

We numb the area thoroughly and work conservatively. Most patients feel only pressure, not pain, during the procedure.

What happens if I wait on a cavity?

Decay spreads over time. A small filling today can turn into a crown or root canal later, so earlier treatment is simpler and more affordable.

Can a filling be replaced if it chips or stains?

Absolutely. We can repair or replace older fillings if they weaken, leak, or no longer match your smile.
