Is Bad Oral Health Linked To Heart Disease? Most people will brush their teeth at least once a day. Brushing teeth will maintain a fresh breath, prevent gum disease, and remove teeth stains. Improving the gum and teeth health will help lower dental bills because it prevents problems in the future. Having bacteria in the mouth can affect the health in many aspects. For instance, some findings have linked poor oral health with respiratory problems, and others have shown that poor gum health raises the risk of developing dementia by 30 to 40 percent. For many years, poor oral health has been debated as a possible risk factor for heart disease. In 2012, experts from the American Heart Association reviewed available scientific evidence and concluded that poor oral health has not been proved to cause heart disease and that treating existing gum disease has not been proved to reduce the risk of heart disease. Yet, mounting evidence has strengthened the link between oral health and heart disease. In a paper published online May 27, 2010 in journal ‘BMJ’, researchers from England analyzed 11,869 participants taking part in a study called Scottish Health Study. Lifestyle habits like smoking, overall physical activity and oral health routines were examined. After adjusting the data for cardiovascular risk factors such as obesity, smoking, social class, and family heart disease history, the researchers found that people who admitted to brushing their teeth less frequently had a 70 percent higher risk of heart disease.
According to researchers, poor oral hygiene is the
major cause of periodontal disease, a chronic infection of the tissues
surrounding the teeth, that seems to add to the inflammatory burden on
individuals, increasing cardiovascular risk. Inflammation plays an important
role in the pathogenesis of atherosclerosis, and markers of low-grade
inflammation have been consistently associated with a higher risk of
cardiovascular disease.
Latest study published December 1, 2019, in the ‘European Journal of Preventive Cardiology’ revealed that toothbrushing 3 or more times a day was connected with a 10 percent lower risk of atrial fibrillation (Afib) and a 12 percent lower risk of heart failure, compared to those who brushed less frequently. For this research, Korean researchers followed 161,286 participants in the Korean National Health Insurance System who aged between 40 and 79 and had no history of Afib or heart failure at study start. Participants had at least one routine medical exam between 2003 and 2004. Details on height, weight, laboratory tests, illnesses, lifestyle, oral health, and oral hygiene behaviors were collected. After an average follow-up of 10.5 years, 3 percent of the subjects (4,911) developed Afib and 4.9 percent (7,971) developed heart failure. Getting regular professional dental cleanings was also tied to a 7 percent lower risk of heart failure while having 22 or more missing teeth was linked to a 32 percent higher heart failure risk. Tooth loss has been correlated in past research with coronary artery disease, according to the American Heart Association. Regular tooth brushing likely reduces bacteria in the so-called subgingival biofilm, the pocket between the teeth and gums, preventing bacteria from entering the bloodstream, as indicated in the report. Some research has found that oral bacteria in the blood clots of people receiving emergency treatment for stroke, and severe gum disease has been linked to a significantly higher risk of hypertension. Poor oral health can also raise the risk of a bacterial infection in the bloodstream that can affect particularly those patients with artificial heart valve. Artificial heart valves have a tendency to collect debris and tend to develop bacterial growth. While the likelihood is low, it seems that bacteria introduced into the bloodstream can cause a prosthetic heart valve to become infected.
While bad toothbrushing habits have so far not
been shown by studies to cause cardiovascular problems, both the American Heart
Association and the American Dental Association have recognized that people with
gum disease (periodontitis) have risk factors that may also damage their heart
and blood vessels. As recommended by the American Dental Association,
individuals should brush at least twice daily and floss once a day to prevent
oral infections, and individuals are also advised to schedule regular checkups
and professional dental cleanings with a dentist. Date: May 21, 2020
