How Do Fillings Work? A Step-by-Step Look Inside the Procedure

July 1, 2025

Tooth pain can arise unexpectedly, often disrupting daily routines. In many cases, the underlying cause is a cavity, a common dental concern. Fortunately, dental fillings provide an effective and timely solution. If you are unfamiliar with how the procedure works, this detailed guide offers a clear, step-by-step overview to help you understand what to expect during your appointment.

What Are Dental Fillings?

Dental fillings in Auburn restore the shape and operation of a tooth damaged by decay. When bacteria eat away at the enamel and dentin, they leave behind a hole, commonly known as a cavity. Left untreated, cavities grow deeper and more painful. Fillings fix that problem early.

There are different types of filling materials, including:

  • Composite resin – tooth-colored and blends well with natural teeth.
  • Amalgam – silver-toned and very durable.
  • Gold – strong, long-lasting, and usually chosen for molars.
  • Ceramic – stain-resistant and aesthetically pleasing.

Your dentist selects the best option based on the tooth’s location, the cavity’s size, and your personal needs.

Signs You Might Need a Filling

You don’t always feel a cavity forming. Sometimes, it quietly eats away at your tooth before you ever notice it. Still, there are some signs that could point to a problem:

  • Pain or sensitivity when eating sweets
  • Discomfort when biting down
  • A conspicious hole or dark spot on the tooth
  • Roughness you can feel with your tongue
  • Sudden sensitivity to hot or cold foods

If you notice any of these issues, don’t wait. Schedule a check-up with a dentist before it worsens. If you’re searching for a trusted local dentist or a dentist in Auburn early diagnosis and treatment can create all the difference in saving your tooth and avoiding more complex procedures later.

Initial Dental Examination

The first step is a dental exam. This helps confirm whether a filling is needed.

Here’s what typically happens:

  • Visual inspection – Your dentist looks for discoloration or visible damage.
  • X-rays – These help catch cavities that aren’t visible on the surface.
  • Probing – A tool checks for soft spots or pits in the enamel.

If the dentist sees signs of decay, they’ll explain the issue and go over your treatment options. For smaller cavities, a filling is usually the best route. If you’re unsure where to begin, consulting a trusted dentist near you can help you feel confident in your next steps.

Preparing for the Procedure

Once you and your dentist decide to move forward, preparation begins. Don’t worry—it’s straightforward and usually pain-free.

Here’s what to expect:

  • Numbing the area – A local anesthetic ensures you don’t feel pain.
  • Placing a dental dam (if needed) – This keeps the tooth dry and isolated during treatment.
  • Confirming comfort – Before starting, your dentist will make sure the numbing has taken full effect.

This stage helps you feel at ease while your dentist prepares to clean and treat the tooth.

Removing Decay

Now comes the part that does the heavy lifting: getting rid of the decayed tissue.

Employing a dental drill or laser, the dentist carefully removes all damaged parts of the tooth. They also clean the area thoroughly to get rid of bacteria and debris. This step is critical—it stops the spread of decay and gives the filling a clean, solid base.

Placing the Filling Material

Once the tooth is cleaned out, the dentist gets ready to fill it.

  • For tooth-colored fillings, layers of composite resin are applied. Each layer is hardened with a special light.
  • For amalgam or other materials, the filling is packed in and shaped to fit snugly.

The filling must seal the area tightly. This keeps bacteria from getting back in and causing trouble.

If you’re searching for dental fillings near you, ask your provider about which material suits your needs best—each has its benefits.

Shaping and Polishing

Filling placement isn’t the end of the job.

The dentist now adjusts the shape so the filled tooth lines up perfectly with the bite. You’ll be asked to bite down on paper to check how the teeth come together. If anything feels high or uncomfortable, the dentist smooths it out.

After shaping comes polishing, which makes the surface smooth, reduces staining and helps the filling blend with the rest of your smile.

A well-shaped filling should feel natural like nothing was ever wrong.

Aftercare Instructions

You’re done with the appointment, but there are a few things to keep in mind for the hours and days that follow.

Right After the Appointment:

  • Wait until the numbness goes away before eating or drinking.
  • Stick to soft foods for the first few hours.
  • Don’t chew on the filled tooth right away if possible.

In the Days Ahead:

  • Watch for sensitivity to hot or cold. This usually fades in a week or two.
  • If the pain lasts or worsens, call your dental office.
  • Brush and floss as normal, but avoid snapping floss hard around the filled area.

Proper care helps your filling last. With good oral habits, fillings can hold up for many years.
