What to Expect When You Get a Dental Filling
You’re sitting in your dentist’s chair for your checkup, and you hear the dreaded words: “You have a cavity.” Is it really time to panic? Modern dental equipment and techniques may surprise you, showing that getting a filling is a straightforward and well-managed process. Here’s what to expect if you need a filling.
Choosing the Right Type of Filling
The first step is discussing the best type of filling for your needs. Two common options are:
- Amalgam Fillings: Known for their durability, these fillings are made from a mixture of metals, including silver and mercury. While they are long-lasting, some patients express concerns about the mercury content.
- Resin Composite Fillings: This newer material contains more plastic and is often preferred for its aesthetic appeal because it matches the natural color of your teeth. However, composite fillings last only about half as long as amalgam fillings.
Numbing the Area
Before the procedure begins, the dentist will numb the area where the filling is needed. For small cavities, the numbing might not be necessary. If it is required, the dentist will apply a topical numbing agent, followed by an injection to ensure the area is fully anesthetized. Many patients don’t feel the injection, thanks to the topical numbing.
Preparing the Tooth
Once the area is numb, the dentist will isolate the tooth using a rubber dam or bite block to ensure the work area remains dry. The dentist will then drill the decayed part of the tooth and remove the damaged material.
Placing the Filling
After the cavity is cleaned out, it’s time to place the filling:
- For Amalgam Fillings: The cavity will be filled with a mixture of metals. The dentist will press the filling down to fill the cavity completely and smooth the surface once any excess material is removed.
- For Composite Fillings: The dentist will apply a blue acid to the cavity, which creates small holes for better bonding. After rinsing off the acid, a bonding agent is applied, followed by the composite material. A special blue light is used to harden the composite, and then the filling is filed down to smooth it out.
Your Next Steps
After the procedure, your dentist will provide you with care instructions to ensure your filling lasts and your tooth remains healthy.
