how long does a filling take

A routine dental filling usually takes about 20–60 minutes per tooth, depending mainly on cavity size, tooth location, and the type of filling material used. More complex or multiple fillings, or custom inlays/onlays, can take closer to an hour or may need a second visit.

How long does a filling take?

For a standard cavity filling appointment, expect something like:

• Simple, small fillings: Around 15–30 minutes per tooth once you are in the chair and numb.

• Medium to large fillings: Often 30–60 minutes per tooth because more tooth structure must be cleaned and rebuilt.

• Multiple fillings in one visit: Time stacks; for example, two modest fillings might be done in about an hour.

• Lab-made inlays/onlays, gold or ceramic: Often require 2 visits: first (about 60–90 minutes) to prepare and take impressions, second (30–60 minutes) to bond the restoration.

In most general-practice situations, people are in and out (including numbing, procedure, and bite check) in under an hour for a single, uncomplicated filling.

What happens during the appointment?

A typical filling visit is broken into short steps, which is why the whole thing can feel fairly quick.

• Exam and X‑rays (5–10 minutes): The dentist confirms the cavity’s size and depth and chooses the best treatment approach.

• Numbing (10–15 minutes): Local anesthetic is injected and allowed to take full effect so the procedure is comfortable.

• Removing decay (5–20 minutes): The dentist cleans out decayed tooth material and shapes the cavity.

• Placing the filling (5–25 minutes):
  • Amalgam is placed and carved in one go, usually faster.
  • Composite is placed in layers and light-cured, which adds time but gives a natural look.

• Shaping, polishing, and bite check (5–10 minutes): The dentist smooths the surface and adjusts your bite so it feels comfortable.

Most of your “clock time” is either waiting for numbness to kick in or for materials to set, not drilling.

How filling type changes the time

Different materials have different placement steps and therefore different time ranges.

• Composite (tooth-colored) fillings:
  • Common in front teeth and visible areas.
  • Typically 20–45 minutes per tooth due to careful isolation, bonding steps, and layering.

• Amalgam (silver) fillings:
  • Often faster to place because they do not require layering.
  • Usually about 15–30 minutes per tooth.

• Glass ionomer:
  • Often used in specific situations (like near the gumline).
  • Around 20–30 minutes per tooth.

• Gold or porcelain/inlay–onlay:
  • Tooth is prepared and an impression or scan is taken; the lab makes the restoration.
  • Typically 2 visits as noted earlier, with a temporary filling in between.

Factors that can make it longer or shorter

Even with averages, the actual time can vary from person to person.

• Cavity size and complexity: Larger or deeper decay, or damage between teeth, takes longer to clean and fill.

• Tooth location: Molars (back teeth) are harder to see and reach, which can add time compared with front teeth.

• Number of fillings: Doing several in one visit is efficient overall but lengthens that single appointment.

• Your general comfort and ability to stay open: Needing more short breaks can extend the chair time, and many dentists will happily pace the work if you’re anxious.

• Technology used: Some modern offices can mill and place same‑day ceramic inlays/onlays, which compresses multiple visits into one somewhat longer appointment.

After the filling: how long until it feels normal?

The filling itself is finished by the time you leave, but your mouth may need a bit more time to settle.

• Numbness wears off: Expect 1–3 hours before your lip, cheek, and tongue feel normal again.

• Sensitivity: Mild sensitivity to cold, heat, or pressure can last a few days to a couple of weeks, especially with deeper or larger fillings.

• Eating: Most people can eat once the numbness is gone, though many dentists suggest starting with softer foods and chewing on the opposite side at first.

If a filling still feels high, painful when biting, or very sensitive after a couple of weeks, a quick adjustment visit is usually all that is needed.
