Charcoal Toothpaste Experiment Results!

Hopefully you have read our recent blog post regarding activated charcoal used to whiten teeth. Today we reveal our Charcoal Toothpaste Experiment Results!

Here we have our beloved Dr. Balice before using any whitening agent. We using a standard shade guide in most dental offices known as the Vita Shade Guide. Dr. Joe began at an A3.

The Product

We selected the Cali White Activated Charcoal and Coconut Oil Toothpaste from Amazon for $10.99. It is a best seller and has stellar reviews.

Most reviews commented after days or a month of use. Dr. Joe used this toothpaste as directed twice daily for four weeks.


I did pose the question on Amazon, “What is the Relative Dentin Abrasivity (RDA)?” As an Amazon Prime member, I shop there frequently and know that the sellers have access to the questions and have the ability to answer them. I did hear back from the manufacturer. They stated it has an RDA of 113. A safe level of abrasivity according to the American Dental Association is below 250. You can read about this standard on the ADA website via the following link. ADA Abrasivity Standard

Our Experiment

We checked in with Dr. Joe every few days. He stated is subjective opinion of it’s whitening effectiveness and we compared his teeth to his initial shade on the Vita Shade Guide.


Using a standard Vita Shade Guide, Dr. Joe began as an A3.

1 Week Check

Dr. Joe felt that he saw a minor difference. We disagreed. Joann, Jennifer and I didn’t feel there was a noticeable difference.

2 Week Check

At this point we all agreed that he was lighter that when he began. His progress was confirmed when compared to the Vita shade guide as he was an A2.


4 Week Check

The final results are in!!! Dr. Joe continued to lighten up, minimally. His final shade was somewhere between A1 and A2.




I was very skeptical of this whole charcoal thing to begin with. I must admit, I am pleasantly surprised. Dr. Joe did whiten up. The Vita shade guide has 5 A shades so the results are impressive. There were no side effects, specifically, no sensitivity as that is the most common side effect of whitening products.

Although I don’t feel the charcoal toothpaste is as effective as the in office whitening treatments, it did work. We can add this to our list of whitening options. It is a safe, effective and inexpensive.
