误区三：怀孕生产后出现牙龈退缩，是因为月子没坐好？错！ 有些女性在生完孩子后，觉得自己的"牙口"大不如前，牙龈也萎缩了，就认为是月子没坐好。实际上， 这是由于孕激素水平剧烈变化，使得口腔中的炎症被放大。很多人在怀孕之前就有口腔问题，但没有发 现或没有引起重视，这些问题往往会在怀孕期间被放大。所以，在备孕阶段就应该进行详细的口腔检 查。还有些人在坐月子期间，对于口腔卫生的维护有着一些错误认知，觉得不应该刷牙或者用一些其他 的手段来清洁，这些都是不可取的。只有科学护理，才能让牙齿更健康。 误区四："老掉牙"是不可避免的？错！ 作者：许桐楷（北京大学口腔医院综合二科副主任医师） 误区一：洗牙会造成牙龈退缩？错！ 很多人觉得，洗完牙后，牙缝反而变大，牙齿反而更长，因而认为洗牙会造成牙龈退缩。其实，在洗牙 之前，这些人的局部牙龈已经受损了，但还没感觉到牙龈退缩。这是因为这些地方的牙龈在炎症的刺激 下，处于肿胀的状态，同时里面可能还塞满了牙结石、食物残渣、牙菌斑等，所以会觉得好像没有牙 缝。实际上，牙缝早已产生，牙龈退缩已经形成了，只有洗牙后并通过每日清洁保持这个牙缝的通畅， 才能够最大限度地避免这个地方继续发生炎症，从 ...

Core Points - The article emphasizes the importance of brushing teeth at least twice a day to maintain oral health and prevent dental issues such as cavities and periodontal disease [4][6]. Group 1: Importance of Brushing Twice Daily - Oral health is threatened by two main enemies: cavities and periodontal disease, caused by bacteria that accumulate on teeth [4]. - Bacterial plaque formation occurs in stages, with significant maturation happening within 24 hours, making it crucial to brush at least twice daily to prevent plaque from becoming difficult to remove [5][6]. Group 2: Importance of Nighttime Brushing - Nighttime brushing is particularly important as it helps control the bacterial load on teeth, especially since saliva production decreases during sleep, reducing natural cleaning [9]. - Brushing at night effectively removes food residues accumulated throughout the day, which can feed bacteria and lead to tooth decay [10]. - Nighttime brushing helps eliminate dental plaque, reducing the risk of cavities and periodontal disease [11]. - It also mitigates oral odor caused by bacteria breaking down food residues, which can be more pronounced if brushing is skipped [12].

Core Viewpoint - The article emphasizes the importance of brushing teeth at least twice a day to maintain oral health and prevent dental issues such as cavities and periodontal disease. Summary by Sections Importance of Brushing Twice Daily - Brushing twice a day is essential to combat the two main enemies of oral health: cavities and periodontal disease, which are caused by bacteria accumulating on teeth surfaces over time [1]. Stages of Plaque Formation - **Initial Attachment (0-2 hours)**: After brushing, a small number of loose bacteria begin to attach to the teeth using a saliva film [2]. - **Bacterial Attachment (2-12 hours)**: More bacteria attach to the teeth, becoming more firmly established [3]. - **Mature Plaque (12 hours)**: Attached bacteria start to reproduce and form a complex biofilm structure, making it harder to remove [4]. - **Fully Matured Plaque (24 hours)**: After 24 hours, plaque becomes a complex microbial community that poses a significant threat to oral health, leading to cavities and periodontal diseases [5]. Importance of Nighttime Brushing - Nighttime brushing is crucial as saliva production decreases significantly during sleep, reducing the natural cleaning effect of saliva [8]. - Food residues in the mouth can lead to an acidic environment that erodes tooth enamel, making nighttime brushing vital to remove these residues [9]. - Bacteria proliferate rapidly at night, and brushing before sleep helps to minimize plaque accumulation and reduce the risk of dental issues [10]. - Oral odor is often worse in the morning due to bacterial activity overnight; brushing at night helps to mitigate this issue [11]. - Oral health is linked to overall health, and nighttime brushing can reduce the risk of chronic diseases by lowering bacterial levels in the mouth [11]. Conclusion - Establishing a nighttime brushing routine is essential for both short-term and long-term oral health, and parents should encourage this habit in their children [11].

Core Insights - The article emphasizes the importance of oral health, particularly highlighting periodontal disease as a significant risk factor for various systemic diseases, including cardiovascular diseases, which are often referred to as "silent killers" [1][3].

Group 2: Prevention and Treatment of Periodontal Disease - Early identification of plaque and tartar accumulation is crucial to prevent the progression of periodontal disease [4]. - Common treatments for periodontal disease include scaling (cleaning), subgingival curettage, periodontal surgery, and tooth extraction, with antibiotics serving only as adjunctive therapy [6]. - Good oral hygiene practices, such as brushing twice daily for at least two minutes and using dental floss, are essential for prevention [7]. Group 3: Oral Cancer Awareness - Oral cancer incidence is rising in China, particularly among middle-aged men aged 40 to 60 [9]. - Common risk factors for oral cancer include smoking, alcohol consumption, and betel nut chewing [10][12]. - Symptoms such as persistent ulcers, bleeding, and unusual growths in the mouth should prompt immediate medical attention [12]. Group 4: Misconceptions in Dental Care - The belief that dental cleaning causes gum recession is incorrect; gum recession is often due to pre-existing inflammation [14][15]. - Not all wisdom teeth need to be extracted; only those that are problematic should be removed [16][18]. - The notion that losing teeth is an inevitable part of aging is misleading; periodontal disease is a primary cause of tooth loss, and maintaining dental health can significantly impact longevity [20].
