99-Year-Old Dentist's 3-Year-Old Warning to Celeb Comes True
Recently, the news of Beijing University teacher Wei Dongyi opening a personal social media account has sparked widespread attention, with his follower count surpassing 15 million as of June 7th and continuing to rise. However, upon closer inspection, netizens noticed that Wei Dongyi has missing teeth, which, according to his family, is due to periodontitis, a condition he has been treated for multiple times and is scheduled for further hospital check-ups. This revelation has brought to light a warning issued by a well-known dentist three years ago, who had expressed concern over Wei Dongyi's oral health, predicting a potential crisis.

The dentist, Chen Liang, also known as "Yáyī Zào Zhibaǒ" (Dental Prosthetics Farmer), had posted about his concerns on social media, highlighting the importance of preventative oral care and regular check-ups to prevent conditions like periodontitis, which can lead to tooth loss if left untreated. As early as November 2022, Chen Liang expressed concern about the oral health of a certain celebrity, stating, "Every time I see Wei God, I still worry about his gum situation. The 30-40 age range is the peak period for gum disease, and I imagine there are many people in this age group who have never had a professional dental cleaning." The blogger's concerns were not unfounded, as they had previously observed signs of gum recession and tooth movement in the celebrity's smile, which are common indicators of gum disease, also known as periodontal disease.
In a more recent post, the blogger revealed that their worst fears had been confirmed, stating "Wei God has been diagnosed with gum disease and is undergoing treatment." The blogger's warning signs had come true, highlighting the importance of regular dental check-ups and proper oral hygiene practices to prevent the onset of gum disease. Periodontal disease, also known as gum disease, is a primary cause of tooth loss. The root cause of periodontal disease is the accumulation of plaque, a complex community of bacteria that not only destroys the gums but also leads to tooth decay. To prevent periodontal disease, it is essential to establish good oral hygiene habits, such as rinsing after meals, learning proper brushing techniques, and scheduling regular dental check-ups.
If bleeding gums are noticed, it is crucial to seek medical attention promptly, preferably during the gingivitis stage, to prevent further damage. According to experts, the gums and jawbone naturally recede with age, but this physiological recession is not sufficient to cause tooth loss. The actual culprit behind tooth loss is periodontal disease, where bacteria infect the gums and jawbone, leading to gingivitis and periodontitis. When teeth lose the support of the jawbone, they become vulnerable to falling out, much like a high-rise building constructed on sandy ground. This is why many elderly individuals often lose intact teeth.
The World Health Organization recommends that individuals aged 80 and above should have at least 20 functional teeth to ensure adequate nutrition. To prevent tooth loss, it is vital to treat oral diseases promptly and undergo regular teeth cleaning. In the case of Wei Dongyi, a dentist had warned of an impending periodontal crisis three years ago, which has now become a reality. This highlights the importance of proactive oral care and regular dental check-ups to prevent tooth loss and maintain overall health. As the prophecy of dentist Wei Dongyi three years ago about the looming dental crisis comes to fruition, it has become increasingly evident that preventive measures against periodontal disease are of paramount importance.
Regular dental cleanings, subgingival scaling, and root planing are among the treatments that can significantly hinder the progression of the disease, thereby preserving teeth. Experts emphasize that maintaining good oral health habits from a young age is crucial, as it lays the foundation for a healthy life. For instance, having at least 20 functional teeth by the age of 80 is considered essential to meet the bodily demands of nutrition and digestion. This underscores the necessity of adopting and adhering to stringent oral hygiene practices throughout one's life, including regular dental check-ups and proper care of teeth and gums. By doing so, individuals can mitigate the risk of periodontal disease and its severe consequences, such as tooth loss and associated health issues. The onus, therefore, lies on both individuals and health care systems to prioritize preventive dental care, ensuring a future where dental health is not overlooked but valued as an integral component of overall well-being.
