Getting a dental filling is one of the most common treatments in dentistry. Whether due to a cavity, minor tooth damage, or wear, fillings restore tooth function and prevent further decay. If your dentist has recommended a filling, knowing what to expect during the procedure can ease anxiety and help you prepare.
This guide walks you through every step of the dental filling procedure, explains how to care for your tooth afterward, and answers the most common patient concerns.
What Is a Dental Filling Procedure?
A dental filling procedure is a restorative material used to fill cavities or repair cracked, broken, or worn-down teeth. The goal is to restore the tooth’s shape, function, and appearance while preventing further decay.
Fillings can be made from various materials, including:
- Composite resin (tooth-colored)
- Amalgam (silver-colored)
- Gold
- Ceramic (porcelain)
- Glass ionomer
Your dentist will recommend the best material based on the location of the filling, your aesthetic preferences, and your budget.
Signs You May Need a Dental Filling Procedure
If you’re wondering whether you might need a Dental Filling Procedure, here are some common symptoms:
- Tooth sensitivity to sweets, cold, or heat
- Visible holes or pits in your teeth
- Dark spots or discoloration
- Sharp pain when biting or chewing
- Food getting stuck in certain areas
Early detection is key. Regular dental checkups help catch problems before they worsen.
Dental Filling Procedure: Step-by-Step
Understanding the process can make it feel much less intimidating. Here’s what typically happens during a dental filling procedure appointment:
1. Examination and Diagnosis
Your dentist will first examine your teeth, possibly using X-rays, to assess the extent of the decay or damage. If a cavity or crack is identified, a filling will be recommended.
2. Numbing the Area
Local anesthesia is applied to numb the area around the affected tooth. This ensures the procedure is comfortable and pain-free.
3. Removing the Decay
Once numb, the dentist uses a dental drill, laser, or air abrasion tool to remove the decayed or damaged portion of the tooth.
4. Cleaning the Cavity
After removing decay, the area is thoroughly cleaned to remove bacteria and debris. This step is crucial to prevent further infection.
5. Placing the Filling Material
The dentist carefully places the chosen filling material in layers. With tooth-colored composite fillings, a special light may be used to harden each layer.
6. Shaping and Polishing
Once the filling is in place, the dentist trims and shapes it to match your natural bite. The surface is then polished for a smooth finish.
The entire procedure typically takes 20 to 60 minutes per tooth, depending on the size and type of filling.
Aftercare for a Dental Filling
Taking proper care of your tooth after a filling is essential not only for comfort but also for making sure the restoration lasts for years to come. Following your dentist’s aftercare instructions reduces the risk of complications such as sensitivity, cracked fillings, or new decay forming around the treated area. Here are key steps to follow for a smooth recovery:
Wait Until Numbness Wears Off
It’s common for your mouth to remain numb for several hours after the procedure. During this time, avoid chewing or drinking hot beverages. Accidentally biting your cheek, tongue, or lip is easy when you can’t feel the area properly, and hot drinks could burn you without you realizing it. Waiting until the anesthesia fully wears off helps you avoid injury.
Be Gentle with the Filled Tooth
If you’ve received an amalgam (silver) filling, it takes longer to fully harden—usually around 24 hours. That means you should chew on the opposite side of your mouth and stick to softer foods until it sets completely. Composite (tooth-colored) fillings harden right away, but even then, being gentle with the tooth for the first day can help with comfort and healing.
Avoid Sticky or Hard Foods
Fresh fillings are more vulnerable to pressure and stress, especially within the first day. Foods like caramel, gum, hard candy, nuts, or crunchy snacks can put stress on the filling and may even cause it to crack or loosen. Instead, opt for softer, easy-to-chew options such as yogurt, soup, or scrambled eggs until your dentist confirms you can return to your normal diet.
Manage Sensitivity
Mild tooth sensitivity is one of the most common after-effects of a filling. You might notice discomfort when eating hot, cold, or sweet foods. This usually improves within a few days, but you can ease symptoms with over-the-counter pain relievers, desensitizing toothpaste, and by avoiding extreme temperatures in food and drinks. If sensitivity persists for more than a week or gets worse, it’s a good idea to call your dentist.
Maintain Good Oral Hygiene
Good oral care helps prevent new cavities around your filling and keeps your teeth and gums healthy. Brush your teeth twice a day using a soft-bristled toothbrush and fluoride toothpaste, making sure to clean gently around the restored tooth. Floss daily, but slide the floss carefully to avoid tugging at the filling. Rinsing with an alcohol-free mouthwash can further reduce bacteria and support gum health.
Extra Tip: Schedule a Follow-Up Visit
In some cases, your dentist may recommend a follow-up appointment to check your bite and ensure the filling is secure. Even if everything feels fine, keeping up with regular dental checkups every six months helps spot potential issues early and ensures your fillings last as long as possible.
Dental Filling Procedure: When to Call Your Dentist
Most dental fillings heal smoothly, and minor sensitivity is nothing to worry about. However, there are certain warning signs that shouldn’t be ignored. If you experience sharp pain or pressure when biting down, it could mean that your filling is sitting too high and your bite isn’t properly aligned. This not only causes discomfort but can also put extra stress on the tooth and surrounding structures, leading to cracks or premature wear.
Persistent tooth sensitivity—especially to hot, cold, or sweet foods—may signal that the nerve inside your tooth is irritated, or that decay is forming around the edges of the filling. In such cases, your dentist may need to adjust or replace the restoration before the issue worsens.
A filling that feels uneven, wobbly, or rough is another red flag. You might even notice food getting trapped around it, which increases the risk of cavities and gum problems. Similarly, if cracks appear or small pieces of the filling chip away, prompt attention is necessary to prevent bacteria from seeping in and causing infection.
The bottom line? Don’t wait until the discomfort becomes unbearable. A quick visit to your dentist for an adjustment or replacement can save you from more complicated (and costly) procedures down the road.
Dental Filling Procedure: How Long Do Fillings Last?
The lifespan of a dental filling depends on the material used and your oral habits:
Filling Material | Average Lifespan |
Composite Resin | 5–10 years |
Amalgam | 10–15 years |
Ceramic | 15+ years |
Gold | 20+ years |
Regular dental checkups allow your dentist to monitor the integrity of the filling and recommend replacement when needed.
Are Dental Fillings Safe?
Yes, dental fillings are considered very safe. Composite and ceramic materials are biocompatible and mercury-free. While silver amalgam contains mercury, extensive studies have shown it’s safe for most people. If you’re concerned, your dentist can recommend an alternative that suits your health needs and preferences.
