Mouthwash is often recommended as an adjunct to oral hygiene routines to help freshen breath, reduce tooth decay, and promote improved oral health outcomes. But what does it mean when mouthwash contains alcohol?
Mouthwash contains alcohol to help fight off and destroy pathogenic or disease-causing bacteria. Research supports that alcohol in mouthwash is effective in fighting gingivitis, preventing cavities, and reducing overall plaque accumulation in the mouth.
New research is now conflicting with the current recommendations and shows that too much use of alcohol-containing mouthwash can kill off the good bacteria in our mouths as well. The balance in our mouths of good and bad bacteria is known as our oral microbiome. Many of these strains of bacteria live in harmony with one another and can help promote oral health, such as our teeth and gums. By using alcohol mouthwash daily, there isa risk of killing off the good bacteria and throwing off the balance. Some individuals using mouthwash report burning and dryness after the use of mouthwash containing alcohol and must refrain from using it entirely.
Alcohol-containing mouthwash can lead to imbalanced microbiomes, dry mouth, ulcers, irritation, allergic reactions, changes in acid levels in the mouth, bad breath, and more! Luckily there are many alcohol-free mouthwash options that reduce the chance of these side effects. Using mouthwash without alcohol may help to better balance the saliva with a more gentle and natural approach. For those who may experience sensitivity and/or burning using alcohol mouthwashes, this symptom is often alleviated when alcohol is removed.Some research also supports that alcohol free mouthwash is best for those that have multiple dental restorations as its gentler on the materials used.
If you have questions regarding what mouthwash is best for you and your oral health, talk to your dental provider to ensure the best choice can be made.
