Can You Replace Old Fillings with Composite?
If you have older metal (amalgam) fillings, you may be wondering whether it’s worth switching to composite. Whether for cosmetic reasons or health concerns, many patients at Sweet Water Dentistry choose to upgrade their restorations—and enjoy a more natural-looking, mercury-free smile in the process.
Let’s walk through what’s involved in replacing old fillings with composite and whether it’s the right decision for you.
Why Replace Amalgam Fillings?
There are a few common reasons patients opt to remove and replace old metal fillings:
- Aesthetic Improvement: Silver fillings are noticeable when you smile, laugh, or speak. Composite blends in naturally.
- Cracks or Wear: Over time, amalgam fillings can corrode, crack, or shrink, leading to gaps or leaks.
- Tooth Sensitivity: Older fillings may no longer seal properly, exposing your tooth to hot or cold temperatures.
- Health Concerns: Some patients prefer to avoid mercury-containing materials, even though amalgam is considered safe by the ADA.
What Is the Replacement Process Like?
At Sweet Water Dentistry, the process of replacing a filling is safe, simple, and usually completed in one visit:
- Evaluation: We examine the existing filling to determine if replacement is needed and feasible.
- Removal: The old filling is carefully removed using high-speed suction to minimize exposure to debris.
- Cleaning and Prep: The tooth is cleaned and prepped for bonding.
- Composite Placement: Composite resin is applied in layers and cured with a special light.
- Shaping and Polishing: The restoration is shaped to match your bite and polished for a smooth, natural look.
Are There Any Risks?
Replacing old fillings is generally safe, but we always evaluate the integrity of the tooth first. If the surrounding enamel is thin or the tooth has cracks, we may recommend additional support such as an inlay, onlay, or crown instead.
We also ensure proper isolation and ventilation during amalgam removal to reduce the risk of inhaling mercury vapor or particles.
Is It Worth It?
For many patients, yes. Composite fillings offer aesthetic advantages, don’t darken over time, and allow for more conservative treatment. Most importantly, they restore confidence in your smile.
Still, not all metal fillings need to be replaced immediately. If an old filling is stable and functioning well, it may be better to monitor it until it shows signs of wear.
Composite Benefits at a Glance:
- Matches your tooth color
- Bonds to tooth for added strength
- Less drilling than amalgam
- No mercury
- Great for visible teeth
Who’s a Good Candidate?
You’re a good candidate for replacement if:
- You dislike the look of your current fillings
- You have old fillings that are cracked or leaking
- You experience sensitivity around existing restorations
- You’re seeking a mercury-free dental option
