Skipping Tooth Brushing at Night Might Lead to Higher Cardiovascular Disease Risk

If you skip brushing your teeth at night, you can increase your risk of cardiovascular disease, which is a very alarming possibility. A team of researchers conducted a study that was recently published in Scientific Reports to investigate whether or not the frequency with which an individual brushes their teeth is associated with a higher likelihood of cardiovascular diseases (CVDs) among individuals aged 20 years or older. The findings are really fascinating, to say the least.

Perspectives on the Study

The participants in this study were all patients who, between April 2013 and March 2016, were admitted to the Osaka University Hospital in Japan for the purposes of receiving a medical evaluation, surgical intervention, or other forms of therapy. Patients who sought perioperative oral care, dental treatment, or infection screening at the hospital’s Unit of Dentistry were also included in the study.

The study took into account a number of different cardiovascular events, such as arrhythmia, hospitalization due to cardiovascular illness for heart failure, angina pectoris, myocardial infarction, and disorders of the valvular and aortic systems that required surgery. The researchers analyzed factors such as the participants’ ages, genders, angina pectoris, and levels of smoking experience.

A total of 1,675 people who participated in the study were divided into four distinct categories. The members of Group MN stated that they brushed their teeth twice every day, once soon after getting up and again before bed, whereas the members of Group Night stated that they brushed their teeth just once before bed. The members of Group M stated that they only brushed their teeth after waking up, but the members of Group None did not mention cleaning their teeth.

All of the people who participated in the research smoked at similar rates; nevertheless, their dental characteristics were somewhat different. For instance, most individuals with deep dental cavities that were more than eight millimeters (mm) were seen in the MN group. A greater number of people in groups None and MN displayed a dental flexibility index of three in comparison to groups Night and M. This difference was significant.

The Takeaway

The largest percentage of participants who reported cleaning their teeth after lunch was recorded by Groups Night and MN, with 44.9% and 24%, accordingly. Very few of the people who participated in the research and were assigned to the M or None group said that they brushed their teeth after lunch.

Several participants in each of the research groups admitted that they did not clean their teeth before bed. This might be due to behaviors picked up from their parents when they were still young, changes in lifestyle, or differences in geographical location. One further reason why people don’t brush their teeth before bed and after lunch is because they have a lack of interest in oral hygiene in general.
