A Note for the Patient Who's Been Researching for Years
You've done the reading.
You've gone down the research rabbit holes at 11pm. You've watched the documentaries. You've read about mercury v***r, about systemic inflammation, about the oral-systemic connection — and something in it resonated deeply with you.
And then you brought it up at your dental appointment. Maybe you asked about your amalgam fillings. Maybe you said you were concerned about the materials being used. Maybe you just asked whether any of this was real.
And you were dismissed.
"Those fillings are totally safe." "That's not evidence-based." "You don't need to worry about that."
You left feeling a little embarrassed. Maybe even a little crazy.
You're not crazy. You're paying attention.
The research connecting oral health to systemic health is extensive and growing. The concerns around mercury amalgam are legitimate enough that many countries have already phased them out entirely. The questions you're asking are the right ones — and you deserve a dentist who treats them that way.
At Bio Dental, we won't dismiss your concerns. We'll sit with you, review your history, explain what we know and what we're still learning, and help you build a plan that actually reflects your health values.
You don't have to convince us that the mouth and body are connected. We already believe it. We built our entire practice around it.
If you've been looking for a dentist who thinks the way you think — we'd love to meet you.

Why I Built Bio Dental the Way I Did.
I've been a dentist for years. And for a long time, I followed the model I was trained in.
I placed materials without deeply questioning their long-term safety. I worked within appointment windows that didn't leave room for real conversation. I treated the mouth like it existed separately from the rest of the body — because that's what dental school taught me, and that's what the system rewarded.
But the more I learned, the harder it became to keep practicing that way.
I started asking different questions. Why are we still placing mercury-based fillings when we know what mercury does in the body? Why are we rushing through appointments when someone is sitting in my chair with a complicated health history and real concerns? Why does dentistry operate as though the mouth is sealed off from everything else — when every system in the body is connected?
I didn't have good answers. Until my mentor showed me a different way to look at the mouth., So I changed how I practiced.
Bio Dental exists because I believe you deserve a dentist who thinks about your whole body — not just the tooth in front of them. A dentist who chooses materials carefully, explains the reasoning, and makes space for you to ask hard questions.
I built this practice for patients who have been searching for something different. People who don't want to be told what to do — they want to understand why. People who take their health seriously and want their dental care to reflect that.
If you've spent time wondering whether your old fillings are affecting you, whether there's a safer alternative to what was recommended, or whether anyone in dentistry actually thinks the way you think — I want you to know that this practice was built with you in mind.
I'm Dr. Candida Castillo. And this is Bio Dental.

If your gums bleed when you brush, that is not normal.
It’s your body signaling inflammation.
And inflammation in the mouth can contribute to inflammation in the body.
It’s something we take very seriously.
Bleeding gums are not something to ignore.
They’re often one of the earliest signs that your body needs support.
