Is brushing twice a day a myth or a must?
Brushing your teeth twice daily is not just advice; it is a crucial step in maintaining optimal oral and overall health. The American Dental Association (ADA) advises brushing for at least two minutes with fluoride toothpaste twice a day. This helps remove food particles, plaque, and bacteria that accumulate on the teeth throughout the day.
According to the Mayo Clinic, plaque is a sticky white film that contains bacteria that produce acids after consuming sugary foods. These acids erode the enamel, leading to cavities and other dental issues. Additionally, when plaque is left uncleaned, it hardens into tartar, which can cause gum inflammation and periodontal disease.
A report by the National Institutes of Health (NIH) supports this, stating that while brushing once a day can maintain oral health to an extent, most people fail to remove plaque effectively with just one brushing session. Consequently, brushing twice daily is widely recommended by dentists to improve plaque control, prevent cavities, and sustain long-term oral health.
Benefits of brushing your teeth twice a day
Brushing twice a day does more than just keep your teeth clean—it has broader health implications.
Prevents cavities and tooth decay: Removing plaque regularly prevents the buildup of harmful bacteria that cause cavities.
Fights bad breath: Bacteria accumulation is a primary cause of halitosis (bad breath), and brushing twice every day keeps your mouth fresh.
Reduces gum disease risk: Tartar buildup can lead to gingivitis and, if untreated, progress to severe gum disease.
Prevents tooth stains: Regular brushing removes surface stains from food, coffee, and smoking.
Promotes overall health: Poor oral hygiene has been linked to various health conditions, including cardiovascular diseases.
Study shows link between oral health and heart disease
The impact of skipping nighttime brushing extends beyond just oral issues. Dr. Kunal Sood, MD, recently shared his insights on Instagram, citing research that links poor oral hygiene to cardiovascular diseases. He explained that when bacteria from the mouth enter the bloodstream, they trigger inflammation, which may increase the risk of heart disease and heart failure over time.
A 2023 study backed this claim, indicating that while a direct cause-and-effect relationship has yet to be established, there is a strong correlation between poor dental hygiene and heart complications. This means that neglecting brushing, especially at night, does not only put teeth at risk but may also contribute to more severe health problems in the long run.
Clearly, brushing your teeth twice a day is not a myth but a must for maintaining oral and overall health. By brushing twice daily, you not only ensure a healthier smile but also reduce the risk of more serious health complications. So, if you’ve been skipping your nighttime brushing routine, it might be time to rethink that habit—your teeth and heart will thank you!
