The last thing you want to hear at the end of a routine dental visit is the word cavity. That means you’re in for another visit, but next time it’s going to come with the sound of drills as you sit and wonder what the dentist is doing in there.

While we can’t change the nature of getting a filling, we can help tamp down your nervousness a bit by sharing what, exactly, is going on in your mouth as your dentist fills your cavity.

So, here’s a step-by-step look at what happens during the procedure.

1. Numbing the Area

To keep you comfortable, the dentist starts by applying a topical gel, followed by a local anesthetic. This numbs the tooth and surrounding gum tissue. If you're nervous, sedation options may be available to help you relax.

2. Removing the Decay

The decayed part of the tooth is removed using a dental drill, laser, or air abrasion tool. Don’t worry — you won’t feel pain thanks to the anesthetic. A suction device keeps the area clean and dry throughout.

3. Cleaning the Cavity

The dentist thoroughly cleans the hollowed space to remove bacteria and debris. This prevents future infection and creates a clean surface for the filling material.

4. Placing the Filling Material

There are several types of dental fillings, including tooth-colored composite resin, silver amalgam, gold, and ceramic. The dentist selects the best option based on the tooth’s location and your preferences.

5. Shaping and Polishing

Once placed, the filling is shaped to match your natural tooth contours and bite. The final step is polishing, which ensures a smooth, comfortable finish.

Quick Aftercare Tips

Mild sensitivity is normal for a few days.
Avoid hard or sticky foods right after the procedure.
Brush and floss as usual to maintain oral hygiene.
