How to remove iron supplement stains from teeth is a question that has been troubling many of us who rely on iron supplements for better health.

Essentially, iron supplements contain ferrous ions, and when they make contact with the saliva in your mouth, it creates a chemical reaction that leads to stains on your teeth.

Here's the good news - at SNOW, we've conducted extensive experiments to find the best solutions to help you remove iron supplement stains from your teeth.

In this blog post, we'll share our tested and proven methods and recommended products to help you maintain a beautiful, stain-free smile.

Let's dive in!

What Causes Iron Supplement Stains?

Iron supplements contain ferrous sulfate, and when you ingest them, some of this iron can mix with the saliva in your mouth. These reactions form compounds called iron sulfide and iron oxide, which cling to your tooth enamel and form yellow or brown tooth stains.

Our research indicates that this discoloration is more pronounced if the iron supplement you take is in liquid form and held in your mouth for extended periods. That's why we recommend using our whitening strips for sensitive teeth to deal with persistent iron supplement stains. They dissolve after 15 minutes, taking years of accumulated stains caused by medications right along with them.

How To Remove Iron Supplement Stains From Teeth

If you're wondering how to remove teeth stains and prevent them in the future after consuming iron supplements, we at SNOW have four essential tips for you.

1. Take Iron Supplements At Designated Times

If you're taking iron supplements, try to take them at least an hour or two before or after drinking coffee or tea. This way, you give your mouth some breathing space to recover from the iron-saliva combination before it gets stained.

And whenever you're in a bind with issues like tea stains between teeth brought on by your favorite beverages, give our teeth whitening dust a whirl. It's made with natural ingredients and specially formulated to tackle yellowish-brown tobacco, tea, and coffee stains between teeth.

2. Brush Your Teeth Regularly

Brushing your teeth after eating and drinking can help remove surface stains before they settle in. Based on our first hand experience, a thorough toothbrushing session keeps your smile bright and your oral health in tip-top shape.

That's why we recommend using our electric toothbrush and daily teeth whitening toothpaste - the dynamic duo of brushing rituals. Together, they utilize LED light technology and hydrogen peroxide to swiftly remove tough teeth stains, like fluoride teeth stains, while protecting your enamel and gums.

3. Rinse Your Mouth After Brushing

After taking your iron supplement, remember to rinse your mouth thoroughly with water. This helps wash away any excess iron lingering in your mouth, reducing the chances of stains forming.

We also recommend using our trusty mouthwash for teeth whitening during your rinsing routine. It's alcohol-free and neutralizes bacteria in your mouth that causes teeth stains, particularly ones that are a direct result of taking iron supplements. It also shows you how to remove chlorhexidine stains from teeth effectively.

And on that note, our research indicates that other brands of mouthwash, including ones containing chlorhexidine, can potentially stain your teeth. For example, did you know that corsodyl mouthwash makes teeth brown too? SNOW's dynamic mouthwash can help you remove corsodyl stains and keep your breath fresh for hours to boot.

4. Moderate Your Diet

You've probably heard the saying, "You are what you eat," which also rings true for your teeth! That's why we recommend cutting down on highly pigmented foods and drinks, like curries and dark berries, that can contribute to teeth staining.

If you find yourself with a yellow spot on your tooth after consuming these items, you can solve this by maintaining a consistent oral hygiene routine and using our trusty whitening foam for teeth.

It cleans dental devices like your braces and aligners, as well as remineralizing your enamel and removing grey stains on teeth near gums to achieve a smile that's bright and healthy.
