Detailed Introduction

Bio Dental is a biological and holistic dental clinic located in North Providence, Rhode Island, with a core philosophy that oral health is intrinsically linked to the health of the entire body. The practice is led by Dr. Candida Castillo, a biological dentist who received her education from the Boston University School of Dental Medicine and holds a fellowship from the Academy of General Dentistry. The clinic's approach goes beyond traditional dentistry by focusing on the use of non-toxic, biocompatible, and metal-free materials, as well as minimally invasive treatments. Services offered at Bio Dental include safe mercury amalgam filling removal following the SMART (Safe Mercury Amalgam Removal Technique) protocol, which includes protective measures to minimize patient and staff exposure. They also utilize advanced technologies such as ozone therapy for disinfection and healing, and offer dental implants made from biocompatible materials like zirconia. Other services include cosmetic dentistry (veneers, whitening, Invisalign), preventive care, and treatments for issues like snoring and sleep apnea using non-surgical laser technology (Fotona LightWalker). The clinic also offers biocompatibility testing to ensure materials are safe for each individual patient. Bio Dental prioritizes patient comfort and education, ensuring that patients are well-informed about their treatment options and the connection between their dental care and their overall wellness. They are a certified mercury-free and amalgam-free practice, and their commitment to a holistic approach is reflected in their use of BPA-free materials and environmentally friendly practices.

I've been to many dentists ( I am not young!) but this is by far the best! Dr. Castillo is kind, warm and extraordinarily skilled. She has done a lot of work for me and I couldn't be more pleased.

Denise, Lisa and the rest of the staff are awesome as well. This is the place to come if you have high standards and even if you really don't like to visit the dentist! Bio dental makes it as easy and stress free as possible!

I needed to have a tooth pulled yesterday, Dr Castillo said I am going to try and save it if that is ok with you. She did and even if I can get another year out of it like she said it would be great. I absolutely love Dr Castillo, she is so caring, thoughtful, talented and amazing at her job. Tara her assistant was also wonderful she explained everything I would experience after the work was done and she was correct.

They make a great team. Anyone would be for the better going to bio dental…. Just love them

I’ve had two fillings and regular cleanings done at Bio Dental, and I couldn’t be happier with the care I’ve received. Everyone in the office is so kind and welcoming. Dr.

Castillo is amazing—she talks you through every step of the process and has such a warm and gentle approach that really puts you at ease. Denise at the front desk is always happy and incredibly helpful, making scheduling and check-in a breeze. I’m so glad I found this office!

I can’t say enough good things about this place! Dr. Castillo is an amazing biological dentist who truly cares about your whole health, not just your teeth. She takes time to explain everything and makes you feel safe, seen, and supported. The entire team is so kind and welcoming.

You can tell they genuinely love what they do. As someone who values natural, root-cause-focused care, I’m so grateful to have found a dentist who gets it. Highly recommend!
