Overview

Hydrogen peroxide was developed by a chemist, Louis Jacques Thenard, in 1818. Since then, it has been integral to dental practices, particularly mouthwash formulas. Today, it’s been more than 100 years since hydrogen peroxide has been part of dental practices for its mechanical cleansing actions.
For an oral rinse in mouthwash, the strength of hydrogen peroxide should not be more than 3%. Hydrogen peroxide is useful but very potent. Hence it should be used very mindfully.
You must be wondering,
-
Is it safe to use hydrogen peroxide as mouthwash?
-
And if yes, what are its Pros & Cons in the long term?
Here is the answer to all your questions. Let us begin with,
Benefits of Using Hydrogen Peroxide As Mouthwash
- Treat Sore Throat
Hydrogen peroxide’s antibacterial properties ward off infections that can cause sore throat. It also loosens the thick mucus from the throat so it can be drained quickly. When saliva in the mouth comes in contact with HP, it makes foam. This foam helps quickly drains the saliva.
- Treat Gum disease
Hydrogen Peroxide eliminates gum diseases and reduces periodontal pathogens, i.e., gingivitis-causing bacteria (Porphyromonas gingivitis) in the mouth. Swishing hydrogen peroxide removes accumulated plaque from teeth and reaches the rear of the oral cavity and the areas where the floss is difficult to reach.
- Healing Canker
Hydrogen peroxide is a popular remedy for canker sores. It releases oxygen which has cleaning effects and destroys the anaerobic bacteria. Hydrogen peroxide, when used in the correct proposition, even prevents the spread of COVID and influenza viruses.
- Fungal Contamination
Hydrogen peroxide is a favorable treatment for fungal contamination of the mouth. It secures the mouth from oral candidosis, a group of yeasts called Candida. Hydrogen peroxide also possesses antiseptic benefits and gives relief from oral thrush.
It is an oxidizing oral rinse that treats acute necrotizing ulcerative gingivitis. It possesses antibacterial and anti-disinfectant properties. It is also a mild antiseptic used in minor cuts, burns, or mild irritation due to dentures, cankers, cold sores, orthodontic appliances, etc.
Risks of Using Hydrogen Peroxide As Mouthwash
-
Toxic when ingested - swallowing hydrogen peroxide can cause serious side effects, including vomiting, illness, and burning digestive disease.
-
Black hairy tongue- If you rinse your mouth using oxidizing agents excessively, it can cause a black hairy tongue. It is a temporary oral condition.
-
Weakened enamel - Use of higher quantity, higher concentration hydrogen peroxide can cause damage to tooth enamel.
-
Side effects of Hydrogen Peroxide: As a mouthwash, it may also cause stinging, redness, and irritation. If these effects last longer, contact your nearest dentist/pharmacist immediately.
Daily usage of hydrogen peroxide as mouthwash is still debatable among various dentists across the globe. Some believe 1 % of hydrogen peroxide is safe and is an excellent antibacterial agent. It is because HP can penetrate the enamel and collagen-rich tissue and can be very damaging if used in more quantity.
In contrast, most dentists believe that HP can do wonders in overall cleaning for oral health. However, it should never be swollen or used at over 3% concentration. When diluted with water, you can use HP for gargling or to ease pain, reduce irritation or eliminate harmful bacteria. In conclusion, highly diluted HP is safe and effective to use occasionally.
