What’s the Process for Getting a Filling—Is It Painful?

November 1, 2025

If you’ve been told you need a filling, it’s natural to wonder what the process feels like. Many people put off treatment because they fear pain, but modern dentistry makes the procedure quick and comfortable. When you search for dental fillings near you, you’ll find that the process is designed to be simple, efficient, and pain-free.

How Long Does a Filling Take?

A common question patients ask is, “How much time will I spend in the chair?” The answer depends on the size of the cavity and the number of fillings needed.

  • Small cavity: Often completed in 20–30 minutes
  • Medium to large cavity: May take 45 minutes to an hour
  • Multiple fillings in one visit: The appointment can last 1–2 hours

Most patients are surprised by how quickly it’s done. You’ll often walk out ready to go back to your day.

What Types of Filling Materials Are Available?

Dentists offer several dental treatment options when it comes to filling materials. Each has its own strengths, so your dentist will recommend what’s best for your tooth and budget.

Common filling materials include:

  • Composite resin: Tooth-colored, blends naturally, great for visible areas
  • Amalgam: Silver-colored, durable, used in back teeth where chewing pressure is higher
  • Gold: Long-lasting, but more expensive
  • Ceramic/porcelain: Matches natural teeth well, stain-resistant

Composite fillings are the most popular today because they look natural and bond well with tooth enamel.

Post-Filling Sensitivity: What’s Normal and What’s Not

Some sensitivity is common after a filling, especially when eating hot, cold, or sweet foods. This usually goes away in a few days.

Normal after a filling:

  • Mild discomfort when chewing
  • Short-lived sensitivity to temperature
  • Slight soreness in the gum around the treated tooth

Not normal:

  • Sharp, lingering pain
  • Pain that gets worse over time
  • Trouble biting down without discomfort

If you notice unusual pain, call a pediatric dentist near me or family dentist right away. Sometimes a simple adjustment can fix the issue.

How to Care for a Tooth After a Filling

Caring for your tooth after a filling is simple, but it makes a big difference in long-term success.

Tips for aftercare:

  • Avoid chewing too hard foods on the treated side for a day
  • Brush and floss gently around the area
  • Stick with soft foods if the tooth feels sore
  • Use a sensitive-tooth toothpaste if needed

Most fillings settle in within a few days, and you’ll forget you even had one placed.

Step-by-Step Process of Getting a Filling

Knowing what exactly to expect can relieve a lot of the anxiety. Here’s how the process usually goes:

  1. Numbing the tooth: Your dentist applies a local anesthetic so you stay comfortable.
  2. Removing decay: Here, the decayed portion of the tooth is carefully cleaned out.
  3. Cleaning and shaping: The area is disinfected and prepared for the filling material.
  4. Placing the filling: The chosen material is applied in layers and hardened with a special light (for composites).
  5. Shaping and polishing: The filling is smoothed to fit your bite naturally.

From start to finish, the goal is to restore your tooth’s strength while keeping you pain-free.

Quick List: Signs You Might Need a Filling

If you haven’t been diagnosed yet but wonder whether you might need one, here are common symptoms:

  • Sharp pain when eating sweets
  • Sensitivity to hot or cold drinks
  • A dark spot or visible hole in your tooth
  • Food getting stuck in the same place
  • Pain when biting down

If you notice these issues, schedule an exam before the problem worsens.
