Does Toothpaste Lower Testosterone?


Toothpaste is an essential part of our daily oral hygiene routine. We use it to brush our teeth, freshen our breath, and maintain a healthy smile. But have you ever wondered if toothpaste can have an impact on our hormone levels? Specifically, does toothpaste lower testosterone? In this article, we will explore this question and separate fact from fiction. So let’s dive in!

Understanding Testosterone

Before we delve into the effects of toothpaste on testosterone levels, let’s first understand what testosterone is and its significance. Testosterone is a hormone primarily found in males, although females also possess it in smaller amounts. It plays a crucial role in the development of male reproductive tissues, muscle mass, bone density, and red blood cell production. Additionally, testosterone influences sex drive, mood, and overall well-being.

The Ingredients in Toothpaste

Toothpaste typically contains a variety of ingredients that contribute to its cleansing and oral health properties. Some common ingredients include fluoride, abrasives, detergents, humectants, flavorings, and preservatives. However, there is no scientific evidence to suggest that these ingredients have any direct impact on testosterone levels. Therefore, using toothpaste as directed is unlikely to lower testosterone.

The Myth of Triclosan

One ingredient that has sparked some concern is triclosan. Triclosan is an antimicrobial agent that has been used in certain toothpastes and other personal care products. It has been linked to potential hormonal disruptions and has raised questions about its impact on testosterone levels. However, the use of triclosan in toothpaste has significantly decreased in recent years due to safety concerns.

The FDA’s Ban on Triclosan

In 2016, the U.S. Food and Drug Administration (FDA) announced a ban on the use of triclosan in certain over-the-counter consumer antiseptic wash products, including toothpaste. The FDA cited the lack of evidence demonstrating the effectiveness of triclosan in these products compared to plain soap and water. This ban further alleviates concerns about triclosan’s potential impact on testosterone levels.

The Role of Endocrine Disruptors

Endocrine disruptors are chemicals that can interfere with the normal functioning of hormones in the body. Some studies have suggested that certain chemicals found in everyday products, including toothpaste, may act as endocrine disruptors. However, the extent to which these chemicals affect testosterone levels remains inconclusive. The regulatory bodies, such as the FDA, continually monitor these chemicals to ensure the safety of consumers.

Frequently Asked Questions (FAQs)

Now, let’s address some common questions related to toothpaste and its potential impact on testosterone levels.

1. Can toothpaste containing natural ingredients affect testosterone levels?

There is no scientific evidence to suggest that toothpaste containing natural ingredients can lower testosterone levels. Natural toothpaste formulations often rely on plant-derived ingredients, which are generally safe and unlikely to disrupt hormone levels.

2. Is fluoride in toothpaste harmful to testosterone levels?

Fluoride is a common ingredient in toothpaste, known for its ability to prevent tooth decay. Numerous studies have been conducted to evaluate the safety of fluoride, and no evidence has been found to link it to testosterone suppression.

3. Are there any specific toothpaste brands to avoid?

As previously mentioned, triclosan has been banned by the FDA in consumer antiseptic wash products, including toothpaste. However, it’s always a good idea to check the ingredients list and opt for well-known and trusted toothpaste brands.

4. Can poor oral hygiene impact testosterone levels?

Maintaining good oral hygiene is crucial for overall health, but there is no direct evidence linking poor oral hygiene to testosterone levels. However, poor oral health can lead to gum disease, which has been associated with various health issues. It’s always recommended to practice proper oral hygiene to prevent any dental problems.


In conclusion, there is no scientific evidence to support the claim that toothpaste lowers testosterone levels. The concerns surrounding triclosan, an ingredient that had been used in some toothpaste formulations, have been addressed through a ban by the FDA. While some chemicals found in everyday products may act as endocrine disruptors, their effects on testosterone levels remain inconclusive. Therefore, using toothpaste as directed and maintaining good oral hygiene practices should not negatively impact testosterone levels. Remember to choose reputable toothpaste brands and consult with dental professionals for personalized advice. Keep smiling and take care of your oral health!
