What Happens If You Don't Dilute Hydrogen Peroxide for Mouthwash?

 

Over the past decades, hydrogen peroxide mouthwash has been a popular household product for whitening teeth and freshening up breath, as well as soothing minor gum irritation. However, this needs to be noted – hydrogen peroxide should be properly diluted before it comes into contact with the mouth at all. It can actually cause more problems than benefits, so it is important to understand what can happen if you don’t dilute it before attempting this popular home remedy.

The Risks of Undiluted Hydrogen Peroxide

The 3% hydrogen peroxide sold in pharmacies is a "low" concentration for household use, but it is still too high for direct contact to the oral cavity. So, what happens if you don't dilute hydrogen peroxide when using it as a mouthwash? The impact can be:

• Undiluted hydrogen peroxide can burn the soft tissues of the cheeks, gums and tongue, leaving white patches, soft tissue soreness, and peeling on the soft tissues.

• Tooth sensitivity - Over time, it may soften the enamel and make teeth more sensitive to hot and cold.

• Disruption of oral bacteria balance- Your mouth is dependent upon a balance of bacteria. A bad taste and dryness can occur for a few days, and sometimes cause irritation, due to undiluted peroxide killing good bacteria.

• Nausea or stomach upset- Undiluted hydrogen peroxide may cause stomach upset or nausea if accidentally swallowed.

These effects are generally preventable by making a proper dilution of solution prior to use.

How to Dilute Hydrogen Peroxide for Mouthwash?

So you've got a bottle of hydrogen peroxide, and you're wondering if it's safe to swish around your mouth — good question to ask before just trying it! The go-to ratio dentists and dental hygienists mention is simple: mix it 50/50 with water, using the regular 3% hydrogen peroxide you'd find at any pharmacy. That dilution takes the edge off and still gives you a bit of antibacterial punch without being too harsh.

Once it's mixed, swish it around for about 30 to 60 seconds — think of it like a longer version of your regular mouthwash routine — then spit it out and rinse really well with water afterward. Two things to keep in mind: don't swallow it (obviously), and don't turn this into an everyday thing for weeks or months unless your dentist knows you're doing it and is fine with it.

Is Hydrogen Peroxide Mouthwash Right for You?

The truth is that hydrogen peroxide will provide you with some quick wins, such as your teeth becoming a little whiter, or surface bacteria being repelled just a little. It's not, however, a substitute for the fundamentals - twice-daily brushing, flossing, and real visits to the dentist. If you have sensitive gums, dental work such as fillings, or are in braces, you should take extra precautions. Caution: Hydrogen peroxide may irritate or be sensitive to some individuals, even when diluted.

Bottom Line

A properly diluted hydrogen peroxide mouthwash can be a valuable occasional addition to your oral hygiene routine, but it is not a long-term whitening or hygiene program — and using a mouthwash that is not properly diluted can be harmful. When it comes to white teeth and healthier gums, it is always best to take the advice of an expert first, especially when it comes to being safe, effective, and lasting.
