Tooth fillings are a simple dental procedure used to treat cavities. They are relatively painless, thanks to the use of local anesthetics, and they take less time than other procedures like tooth crowns, root canals, and extractions. Knowing what to expect can alleviate some of the anxiety patients tend to feel before going to the dentist. Below is a brief guide to the procedure. 

Tooth Fillings in 5 Steps

1. Numb the Area

Your dentist will start by numbing the tooth and the surrounding gums. This ensures the procedure is as painless as possible. Since many patients have a fear of needles, dentists typically apply a topical numbing gel first. Once the gel is working, they can administer the anesthetic.

2. Prepare the Tooth

Once the area is numb, your dentist will prepare the tooth. Typically this involves placing a rubber dental dam around it. This keeps it dry and also prevents bacteria from getting into it as your dentist works. Depending on the location of the cavity, they may also place a bite block between the upper and lower teeth so your jaw can relax. If you’re getting a tooth-colored filling, they will select the appropriate shade at this time.

3. Remove the Decay

During this process, the dental assistant will use another tool to suction out moisture and debris. A slower-speed handpiece is then used to refine the tooth.

4. Place the Tooth Filling

Placement of the tooth filling varies slightly depending on if you opt for a metal amalgam or tooth-colored composite. An amalgam filling must first be mixed at a high speed to incorporate a small amount of mercury. For a composite filling, an acidic gel is applied to improve the bond between the tooth and the material. Once those processes are complete, the dentist places the filling in the tooth and then uses a curing light to harden the material.

5. Make Final Adjustments

After the tooth filling has hardened, your dentist will have you bite down on carbon paper to check its height. If it’s too high, they can file it down so it’s flush with your tooth surface. After that, you’re free to go. It usually takes a couple of hours for the numbness to wear off, so you may want to avoid eating or drinking anything until then.
