Oral health is often associated only with the whiteness of the teeth, the formation of cavities, or an aesthetic smile. However, oral and dental health is a much broader area of health that affects the entire body. Gum diseases are also one of the most important topics within this holistic structure. Studies conducted in recent years show that the bacteria causing gum diseases do not only create problems inside the mouth; they can also be associated with different systems of the body.
Dr Dt Candan Pelin Güneş, from Bahçeşehir University Faculty of Dentistry Oral and Dental Health Hospital, points out that the bacteria causing gum diseases can increase the risk of Alzheimer's. The content on BUEKMİM conveys that oral and dental health is of great importance for the whole body, and that gum diseases can be associated with some systemic disorders.
Gum diseases begin with the accumulation of bacterial plaque inside the mouth. When this process is not brought under control in time, it can lead to problems such as gingivitis, bleeding, sensitivity, gum recession, and bone loss. However, the problem may not remain limited to the inside of the mouth. The source content states that bacteria formed in the mouth can enter the bloodstream over time, and that this situation can affect chronic illnesses, diabetes, heart, and respiratory disorders. It is also expressed that bacteria causing gum disease can cross the blood-brain barrier, causing neuroinflammation and increasing the risk of Alzheimer's.
For this reason, oral care should be treated as a health habit far beyond a daily hygiene routine. Regular brushing, using dental floss, interdental brushes, and dentist check-ups are among the essential steps to protect gum health. Dr Dt Candan Pelin Güneş states that brushing alone is not enough, and that using dental floss and interdental brushes is important for cleaning the spaces between teeth. Additionally, a brushing routine of twice a day for two minutes is recommended.
From the perspective of BAU Dental Campus and BAU Dental Hospital, oral health is not treated merely as a treatment-oriented field; it is evaluated along with preventive medicine, awareness-raising, early diagnosis, and a holistic health approach. The association of gum diseases with the risk of Alzheimer's makes the impact of oral health on quality of life more visible.
A healthy mouth is one of the important parts of a healthy body. Therefore, regular dental check-ups, correct care habits, and the protection of gum health are a strong health investment for the future.
