Have you noticed any dark fillings in your mouth? Those are likely amalgam fillings, a traditional material used to repair cavities. While amalgam fillings have served us well for many years, they have some drawbacks. Today, more and more people are choosing to replace their amalgam fillings with composite resins.

In this guide, we'll explore the reasons why people choose to replace their amalgams, the process involved, and what to expect before and after the procedure.

Why Replace Amalgams with Composite Resins?

There are several reasons why patients choose to replace their amalgam fillings with composite resins:

•	Appearance: Amalgam fillings are silver-colored, which can be noticeable, especially in the front of the mouth. Composite resins can be matched to the color of your natural teeth, providing a more aesthetically pleasing result.
•	Tooth Structure: Amalgams require the removal of healthy tooth structure to create retention. Composite resins bond directly to the tooth, requiring less removal of healthy tooth structure.
•	Sensitivity: Amalgam fillings can expand and contract with temperature changes, which can cause sensitivity to hot and cold. Composite resins do not have this issue.
•	Durability: While amalgams are strong, they can chip or crack over time. Composite resins are less prone to chipping and cracking, especially when cared for properly.
•	Safety: Amalgams contain mercury, a substance that has been linked to health concerns. While the amount of mercury released from amalgam fillings is considered low, some patients choose to remove them for peace of mind.

The Replacement Process

Replacing amalgam fillings with composite resins is a relatively simple procedure. Here's what you can expect:

1~	Consultation: During your consultation, your dentist will discuss your concerns and examine your amalgams. They will also discuss the benefits and risks of replacing your fillings.
2~	Numbing: Your dentist will numb the area around the tooth to ensure your comfort during the procedure.
3~	Removal of the Amalgam: Your dentist will carefully remove the amalgam filling. They will take special precautions to minimize the release of mercury vapors.
4~	Preparation of the Tooth: Your dentist will prepare the tooth for the composite resin filling. This may involve removing some decayed tooth structure and shaping the tooth to receive the filling.
5~	Placement of the Composite Resin: Your dentist will apply the composite resin to the tooth in layers, shaping and sculpting it to match the contours of your natural tooth.
6~	Curing: A special light is used to harden the composite resin.
7~	Polishing: Your dentist will polish the composite resin to a smooth finish.

The entire procedure usually takes about 30-60 minutes per filling, depending on the size and complexity of the filling.

What to Expect After the Procedure

After the procedure, you may experience some mild sensitivity to hot and cold. This is normal and should subside within a few days. You may also experience some soreness or discomfort in the area where the filling was placed. This can be managed with over-the-counter pain relievers.

It is important to maintain good oral hygiene after having your amalgams replaced. This includes brushing twice a day, flossing daily, and using an antiseptic mouthwash. You should also see your dentist for regular checkups and cleanings.

Conclusion

Replacing amalgam fillings with composite resins is a safe and effective way to improve the appearance and health of your smile. If you are considering replacing your amalgams, talk to your dentist to learn more about the procedure and whether it is right for you.
