Biological and Holistic Dentistry – North Providence, RI

Taking Care of Your Body and Your Smile

Your teeth and gums aren’t isolated from the rest of the body. They’re part of an entire system, and as such problems that affect your oral health are often tied to the rest of the body. Dr. Castillo understands this relationship very well, which is why she opts for a biological approach to dentistry, also sometimes known as holistic dentistry. In fact, she's been voted RI's Top Dentist by RI Monthly Magazine 7 years running in large part for her use of biological dentistry at her North Providence, RI dental office! If you call and schedule an appointment with the Aesthetic Dental Studio of RI, you’re making a decision that will benefit your overall health.

What Is Biological Dentistry?

Biological dentistry focuses on how the body and mouth affect each other and finding alternative, natural treatment solutions. Traditional dental services like biannual cleanings are still performed, of course, but we also take the time to consider all of the different aspects of your lifestyle and the way if factors into your health. By carefully considering your diet, habits, lifestyle, and other factors, we can narrow down the root cause of your oral health issues and suggest simple changes you can make to protect yourself.

Biological Methods of Improving Your Smile

Part of the biological or holistic philosophy of dentistry is staying away from potentially hazardous dental substances. Not only do we only use safe, biocompatible materials like composite resin and porcelain, but we can also help remove and replace mercury fillings. We’ll be sure to take the time to teach you about our biological dental techniques so that you fully understand the kinds of treatment that we have to offer. Examples of biological dental techniques include:

SMART Safe Amalgam Removal

By using the SMART protocol, which stands for “Safe Mercury Amalgam Removal Technique”, we can remove your amalgam fillings while protecting you from additional mercury exposure. Then a biocompatible composite filling can be placed instead. SMART stands for Safe Mercury Amalgam Removal Technique and is a strict protocol that we follow to ensure the safety of our patients. These safety practices include:

  • Each room where mercury fillings are removed have adequate filtration.
  • Protective gowns are included for the patient, dental team, and dentist.
  • Non-latex nitrile gloves are utilized by the dental team.
  • External air or oxygen will be delivered via a nasal mask.
  • Water will be administered to the site to reduce heat.

These are only a few of the long list of safety precautions that we take during tooth extractions and amalgam restoration removal.

Ozone Therapy

Ozone therapy is used to remove bacteria from the entire mouth in the event that the teeth or gums are infected. The ozone gas is simply applied to the teeth and gums to get rid of harmful organisms, providing a noninvasive solution to help the mouth heal from gum disease and other conditions.

Mercury-Free Fillings & Composites

Our fillings and restorations are made out of mercury-free materials. Mercury has been known to contribute to all sorts of neurological and behavioral disorders, but fortunately we have alternatives that are both healthier and more image friendly.

P R P and P R F therapy system

PRP & PRF Therapy

When performing surgical procedures, our patients’ safety and comfort is the #1 priority. That’s why we use PRF (platelet-rich fibrin) and PRP (platelet-rich plasma) therapy to support the healing process. These products are made using the patient’s own blood, and their application enhances natural healing after procedures are complete. This means less inflammation, less bleeding, and a noticeably decreased risk of postoperative infection. Better yet, since it’s made from the patient themselves, there’s no risk of an allergic or immunologic reaction either!
