Best alcohol free mouthwash for gums (Pros and cons of mouthwash with alcohol)

Mouthwashes have long been recognized as valuable tools in the prevention and treatment of various oral and oropharyngeal diseases, ranging from gingivitis to more severe inflammatory conditions like periodontitis.

These formulations often incorporate a range of therapeutically active ingredients, such as essential oils, chlorhexidine, fluoride, potassium nitrate, and benzydamine, each designed to address specific oral health concerns.

However, one common ingredient present in the majority of mouthwashes is alcohol, specifically ethanol, which has been associated with discomfort and dryness, especially for those with sensitive gums.

Thankfully, a wide range of alcohol-free alternatives is available, each designed to promote healthy gums without the drawbacks of alcohol-induced irritation. Say goodbye to the burning sensation and embrace a refreshing, soothing experience with these top-rated alcohol-free mouthwashes that have gained the trust of users and professionals alike:

Pros and cons of mouthwash with alcohol

Pros and cons of mouthwash with alcohol

Clinical trials have shown that alcohol-free mouthwashes can be as effective as their alcohol-based counterparts. Notably, alcohol-free alternatives often exhibit fewer side effects, further underscoring the limited therapeutic impact of ethanol at the concentrations found in most mouthwashes.

This suggests that the primary advantage of alcohol-free formulations lies in their ability to deliver therapeutic benefits without the potential drawbacks associated with alcohol content.

The Role of Alcohol

Alcohol is added to mouthwashes for a few reasons:

  • It helps dissolve active ingredients
  • Acts as a germ-killing agent
  • Keeps the mouthwash stable.
  • It’s a common ingredient because it’s easy to make and not too expensive.

How much alcohol is in mouthwash?

While ethanol is included in mouthwashes for its solubilizing properties, its concentration in these formulations varies. The alcohol content typically ranges from 0% to 27%, yet, interestingly, the optimal concentration for ethanol to exert its antiseptic effect is around 50% to 70%, which significantly surpasses the levels present in mouthwashes.

This relatively lower concentration raises questions about the extent to which ethanol contributes to the therapeutic effects of mouthwashes beyond its role as a solvent.

Disadvantages of Alcohol-based Mouthwashes

a. Alcohol is absorbed in the body

Mouthwash ingredients, including alcohol, get absorbed in the mouth due to the oral mucosa’s high permeability and blood supply. Even low amounts of alcohol (as little as 12% ethanol) in mouthwashes can be detected in urine, showing absorption through the oral mucosa. Breath analyzers used to test alcohol consumption can give positive results after using alcohol-based mouthwashes, highlighting the significant absorption of alcohol in the mouth.

b. It is metabolized into acetaldehyde carcinogen

Alcohol in the mouth behaves similarly to alcohol in beverages and can be metabolized by oral bacteria. Metabolism produces acetaldehyde, a toxic substance known that is harmful to cells and may increase oral cancer risk in people with poor oral care. Unlike other body tissues, the mouth lacks enzymes to break down acetaldehyde, which can lead to its accumulation in the mouth.

Acetaldehyde in mouthwash is considered problematic because:

  • Acetaldehyde is a carcinogen – There is evidence linking acetaldehyde to increased cancer risk, especially oral cancers. Any exposure should be minimized.
  • It is an irritant – Acetaldehyde can irritate and inflame oral tissues, especially with frequent exposure. This can worsen issues in those already with gum inflammation or recession.
  • It triggers alcohol metabolism – Even without drinking, acetaldehyde triggers alcohol metabolic processes in the mouth that disrupt oral microflora.
  • It may cause DNA damage – Studies indicate acetaldehyde has mutagenic effects and can bind to DNA in cells, causing damage and increasing cancer risk.
  • It exacerbates dry mouth – Acetaldehyde exacerbates the alcohol-induced dry mouth caused by many mouthwashes, further impacting oral health.
  • It has a strong odor – The pungent odor of acetaldehyde makes many alcohol-containing mouthwashes unpleasant.

While some exposure may occur incidentally, choosing acetaldehyde-free oral care products reduces unnecessary exposure to a carcinogenic compound that has no benefit to oral health and poses several risks.

c. Increases permeability of oral tissues

Concentration of ethanol in mouthwash affects the permeability of oral mucosa, with higher concentrations increasing permeability. Even as low as 25% ethanol concentration can lead to significantly higher permeability, allowing harmful substances to penetrate the oral tissues.

As such, alcohol in mouthwashes might:

  • Allow harmful tobacco substances to penetrate mouth tissues.
  • Damage mouth lining, leading to tissue thinning and changes in cell growth
  • Lead to mouth discomfort, burning sensation, dryness, and even affect dental fillings.
