Peroxide’s antibacterial properties can help your body fight infections that cause sore throats. It is also helpful in loosening the hardened or thick mucus. This loosening helps the mucus to drain easily, relieving irritation and pain.

When the mucus in your mouth comes into contact with peroxide, it creates a foam. This foam makes your mucus less sticky thus helping to drain it out.

Especially for adults and young children who have a hard time gargling without swallowing, they can try other alternatives. You can try gargling with warm salt water for similar benefits. 

For salt water gargling, mix a tablespoon of salt in one cup of water. Swish this saltwater mixture in your mouth for about 60 seconds, then spit it out. 

4 Healing canker sores

As you know, hydrogen peroxide is antiseptic, which can help to heal canker sores and even cuts. After applying it to a cut or sore, the solution foams and releases oxygen. This foam helps to clean the area by reducing bacteria.

  • Take one part of the 3% peroxide solution and mix it with two parts of water. This is the strength of the solution you will find in a brown bottle at most drug stores. But in a scenario you buy 1% solution, you no longer need to dilute it.
  • Do not use peroxide daily and use it for short periods of time. And only try using it if you have inflamed gums or a sore throat.

  • Spit the solution out after you have finished gargling. Do not try to gargle for more than 90 seconds, as it might be harmful.

What are Dentists Saying?

It is indeed interesting to know that all dentists do not agree on the safety of hydrogen peroxide. Some dentists believe that 1% hydrogen peroxide solution is an excellent antibacterial agent, but it should not be used too often.

The primary reason being the solution can penetrate your enamel, dentin, and finally, the collagen-rich tissue situated within the dentin, damaging it at the end. Some dentists also do not recommend peroxide rinses for whitening teeth. This is because of high concentrations, which could harm your oral mucosa.

Higher concentrations should only be used for professional dental use because your gums are protected with hardening resins or a liquid rubber dam during dental procedures. Your dentist knows the right concentration of the solution to use.
