Weleda Salt Toothpaste Review: Pros and Cons of using salt toothpaste

Weleda Salt Toothpaste Review: Pros and Cons

When it comes to dental hygiene, your choice of toothpaste is crucial to maintaining your oral health. Toothpaste plays a pivotal role in serving not just to clean teeth but also to protect against various dental issues such as decay, gum disease, and plaque buildup. 

The most common toothpastes on the market contain fluoride, designed to prevent tooth decay and strengthen tooth enamel. However, some individuals opt for fluoride-free alternatives, with the main concern being the development of fluorosis (discolouration of the teeth)1

This has led to the availability of a range of fluoride-free toothpastes that use alternative ingredients to support oral health, such as salt toothpaste. But is salt toothpaste good for your teeth? In this blog we explore the popular Weleda Salt Toothpaste. Since its introduction in 1973, it has become a cult classic, now selling a tube every 6 seconds, so let’s uncover real advantages and disadvantages Weleda's Salt Toothpaste based on scientific evidence.

Is Salt Toothpaste Good For Your Teeth?

Weleda salt toothpaste review

Salt toothpaste focuses on natural oral hygiene practices and has anti-inflammatory properties2. The salt acts as a natural cleansing and antibacterial ingredient that may help maintain dental health. The key function of salt in oral hygiene is its ability to stimulate salivation3, which neutralises acids in the mouth, and rinses away food particles, to reduce the risk of dental erosion4 .

Salt toothpastes may also act as a natural mild abrasive which is thought to fade surface stains, however there is no scientific evidence indicating it’s teeth whitening capabilities. 

What does Weleda salt toothpaste do?

Weleda Salt Toothpaste is a unique fluoride-free toothpaste that combines sea salt with gentle mineral cleansers to support the body's natural processes for cleaning teeth by stimulating salivation. The addition of salt in this formula is believed to enhance the cleaning effectiveness of its other natural ingredients including sodium bicarbonate, which neutralises harmful plaque acids and prevents the accumulation of plaque, tartar, or stains. A systematic review published in the International Journal of Dental Hygiene tested the efficacy of sodium bicarbonate against plaque and found that participants who used toothpaste with sodium bicarbonate had significantly lower plaque scores than those who didn’t5.

Other ingredients in Weleda’s salt toothpaste include soothing myrrh and ratanhia, along with horse chestnut bark extract, to support gum health 6,7,8.

The formula is fluoride-free to align with Weleda’s philosophy of using natural ingredients that work in harmony with the body's own processes for maintaining oral health. It caters to individuals seeking purely natural oral care products and for those who have concerns about using flouride toothpastes.

What is the difference between salt and fluoride toothpaste?

The primary difference between salt and fluoride toothpaste lies in their active ingredients and how they aim to improve oral health. While salt toothpaste focuses on supporting the body's natural processes for maintaining oral hygiene, fluoride toothpaste provides a direct approach to preventing tooth decay through chemical means. 

This distinction makes each type of toothpaste suitable for different preferences and needs, with salt toothpaste often chosen by those looking for natural oral care options and fluoride toothpaste preferred for its proven effectiveness in cavity prevention.

Is it okay to use Weleda salt toothpaste everyday?

Using salt toothpaste daily may suit those who are at low risk for cavities and maintain good dietary and hygiene habits. However, for individuals prone to dental caries, incorporating fluoride for its proven cavity-prevention benefits is advisable9. Ultimately, the choice between salt and fluoride toothpaste should reflect your personal oral health needs and preferences, and it's best made in consultation with a dental professional to ensure a balanced and effective oral care routine.

Frequently Asked Questions

Can you apply salt directly to the teeth?

Some DIY remedies for teeth whitening recommend applying salt directly to the teeth, however we strongly advise against this. As the salt is not combined with the right ingredients, it can be highly abrasive, leading to possible enamel erosion.
