National Mouthwash Day
Celebrated on 12/20/2026
Quick Fact
National Mouthwash Day, observed on December 27th, encourages people to incorporate mouthwash into their daily oral hygiene routine. It was established to highlight the benefits of mouthwash in reducing plaque, gingivitis, and bad breath, complementing brushing and flossing.
Origins and Establishment of National Mouthwash Day
National Mouthwash Day was created in 2019 by Dr. Kami Hoss, a renowned dentist and co-founder of The Super Dentists, a pediatric dentistry and orthodontic practice in San Diego, California. Dr. Hoss aimed to raise awareness about the importance of mouthwash as an essential part of oral care, especially during the holiday season when sugary treats and drinks are abundant. The date December 27th was chosen strategically to encourage people to refresh their oral hygiene routine after the Christmas festivities.
Evolution and Modern Commemoration
Since its inception, National Mouthwash Day has grown in popularity through social media campaigns, dental office promotions, and partnerships with mouthwash brands. Dental professionals use the day to educate patients on proper mouthwash usage, including the correct swishing time and the importance of alcohol-free options for those with sensitive mouths. Modern celebrations often include free mouthwash samples at dental clinics, online quizzes to test oral health knowledge, and hashtags like #NationalMouthwashDay to spread the message.
