The TED-Ed animation watched 7.6 million times, explained TED-Ed's animation "What causes cavities?", presented by Mel Rosenberg, has more than 7.6 million views on the TED-Ed site. It starts with archaeology — human remains from around 15,000 years ago already show cavities — then zooms into the tooth surface to show how bacteria in plaque turn sugar from food into acid that slowly dissolves the tooth. The World Health Organization says untreated decay in permanent teeth is the most common health condition worldwide. https://www.youtube-nocookie.com/embed/zGoBFU1q4g0 2026-09-25T17:58:18.923Z yes https://hkdentalguide.com/news/video-ted-ed-crooked-teeth-ancestors https://i.ytimg.com/vi/li1kO3hg4iE/hqdefault.jpg 點解現代人牙齒咁唔整齊？TED-Ed 動畫：祖先原來大多牙齒整齊 TED-Ed 動畫《Why do we have crooked teeth when our ancestors didn't?》由學者 G. Richard Scott 講解，TED-Ed 網站顯示近 490 萬次觀看。影片指出，化石證據顯示古代人類牙齒通常排得整齊，牙齒擠擁係比較近代先普遍嘅現象；影片提出嘅主要解釋，同現代飲食變得軟熟、牙骹發育受影響有關。 https://www.youtube-nocookie.com/embed/li1kO3hg4iE 2026-09-25T17:58:18.923Z yes https://hkdentalguide.com/en/news/video-ted-ed-crooked-teeth-ancestors https://i.ytimg.com/vi/li1kO3hg4iE/hqdefault.jpg Why do we have crooked teeth when our ancestors didn't? A TED-Ed video explained TED-Ed's animation "Why do we have crooked teeth when our ancestors didn't?", presented by G. Richard Scott, has nearly 4.9 million views on the TED-Ed site. It shows that fossil evidence points to ancient humans usually having straight teeth, and that crowding is a comparatively recent problem; the main explanation it offers links softer modern diets to how our jaws grow. https://www.youtube-nocookie.com/embed/li1kO3hg4iE 2026-09-25T17:58:18.923Z yes https://hkdentalguide.com/news/video-george-washington-dentures-myth https://i.ytimg.com/vi/cEmevEacwbI/hqdefault.jpg 華盛頓總統戴木假牙？美國總統故居：從來冇用過木 美國首任總統華盛頓故居 Mount Vernon 網站收錄咗一條教育短片，帶大家近距離睇佢嘅假牙。Mount Vernon 指出，華盛頓 1789 年首次就職時只剩一隻真牙；佢嘅假牙用過錫、金、鉛同人類牙齒等材料，但從來冇用木。「木假牙」傳說相信源於假牙物料日子耐咗染色，睇落似木紋。 https://www.youtube-nocookie.com/embed/cEmevEacwbI 2026-09-25T17:58:18.923Z yes https://hkdentalguide.com/en/news/video-george-washington-dentures-myth https://i.ytimg.com/vi/cEmevEacwbI/hqdefault.jpg Did George Washington wear wooden teeth? His Mount Vernon estate says never George Washington's Mount Vernon estate features a short educational video taking a close look at his dentures. Mount Vernon says that at his first inauguration in 1789 Washington had only one natural tooth left, and that his dentures used materials such as tin, gold, lead and human teeth — but never wood. The "wooden teeth" story most likely comes from the materials staining over time and looking like wood grain. https://www.youtube-nocookie.com/embed/cEmevEacwbI 2026-09-25T17:58:18.923Z yes https://hkdentalguide.com/blog/full-arch-implant-maintenance-hk https://i.ytimg.com/vi/5HxVGPVIVzE/hqdefault.jpg 全弓固定假牙方案嘅優點與風險 全弓固定假牙方案嘅優點與風險 https://www.youtube-nocookie.com/embed/5HxVGPVIVzE 2024-11-23T00:00:00.000Z yes https://hkdentalguide.com/en/blog/implant-loose-peri-implantitis-hk https://i.ytimg.com/vi/0XihCOZzmZM/hqdefault.jpg Dental Implant Success and Failure: Case Discussion Dental Implant Success and Failure: Case Discussion https://www.youtube-nocookie.com/embed/0XihCOZzmZM 2025-01-08T00:00:00.000Z yes https://hkdentalguide.com/en/blog/full-arch-implant-maintenance-hk https://i.ytimg.com/vi/Lb_SdTX7Um8/hqdefault.jpg Full-Arch Fixed Options: Benefits and Risks Full-Arch Fixed Options: Benefits and Risks https://www.youtube-nocookie.com/embed/Lb_SdTX7Um8 2024-11-29T00:00:00.000Z yes https://hkdentalguide.com/en/blog/first-dental-visit-guide-hk-2026 https://i.ytimg.com/vi/pas_2chM_sY/hqdefault.jpg Taking Your Child to the Dentist: What Parents Should Know Taking Your Child to the Dentist: What Parents Should Know https://www.youtube-nocookie.com/embed/pas_2chM_sY 2025-04-29T00:00:00.000Z yes https://hkdentalguide.com/en/blog/pediatric-dentistry-guide-hk-2026 https://i.ytimg.com/vi/GTO8N9cT7ak/hqdefault.jpg Children's Oral Care Q&A: Brushing Baby Teeth Children's Oral Care Q&A: Brushing Baby Teeth https://www.youtube-nocookie.com/embed/GTO8N9cT7ak 2025-04-27T00:00:00.000Z yes https://hkdentalguide.com/blog/pediatric-dentistry-guide-hk-2026 https://i.ytimg.com/vi/AQHX35P6Tlg/hqdefault.jpg 小朋友口腔護理Q&A：乳齒清潔與刷牙習慣 小朋友口腔護理Q&A：乳齒清潔與刷牙習慣 https://www.youtube-nocookie.com/embed/AQHX35P6Tlg 2025-01-09T00:00:00.000Z yes https://hkdentalguide.com/blog/porcelain-veneers-hk-guide-2026 https://i.ytimg.com/vi/ftrTZNGogSg/hqdefault.jpg 瓷牙貼片常見失敗原因與成功關鍵 瓷牙貼片常見失敗原因與成功關鍵 https://www.youtube-nocookie.com/embed/ftrTZNGogSg 2025-02-24T00:00:00.000Z yes https://hkdentalguide.com/en/blog/porcelain-veneers-hk-guide-2026 https://i.ytimg.com/vi/jOLGaLYpu1g/hqdefault.jpg Key Factors for Long-Lasting Porcelain Veneers Key Factors for Long-Lasting Porcelain Veneers https://www.youtube-nocookie.com/embed/jOLGaLYpu1g 2025-02-24T00:00:00.000Z yes https://hkdentalguide.com/en/blog/dr-sarah-lai-pediatric-dentistry-guide https://i.ytimg.com/vi/3l3zEl2oiRk/hqdefault.jpg Dental Decay in Children: Causes, Prevention and Treatment Dental Decay in Children: Causes, Prevention and Treatment https://www.youtube-nocookie.com/embed/3l3zEl2oiRk 2025-08-11T00:00:00.000Z yes https://hkdentalguide.com/blog/cracked-tooth-treatment-hk-guide https://i.ytimg.com/vi/w1TTwdb3k2I/hqdefault.jpg 門牙斷裂怎麼辦？修復齒科專科醫生解答 門牙斷裂怎麼辦？修復齒科專科醫生解答 https://www.youtube-nocookie.com/embed/w1TTwdb3k2I 2025-02-18T00:00:00.000Z yes https://hkdentalguide.com/en/blog/children-braces-age-guide https://i.ytimg.com/vi/JExSuPz9YS8/hqdefault.jpg Early Orthodontic Treatment for Children (Part 1) Early Orthodontic Treatment for Children (Part 1) https://www.youtube-nocookie.com/embed/JExSuPz9YS8 2025-09-01T00:00:00.000Z yes https://hkdentalguide.com/blog/tooth-wear-bite-collapse-hk https://i.ytimg.com/vi/yjj7pfh3_qA/hqdefault.jpg 牙齒磨損如何治療？全口修復攻略 牙齒磨損如何治療？全口修復攻略 https://www.youtube-nocookie.com/embed/yjj7pfh3_qA 2025-02-04T00:00:00.000Z yes https://hkdentalguide.com/en/blog/tooth-wear-bite-collapse-hk https://i.ytimg.com/vi/MvMyH-jqK24/hqdefault.jpg Full Mouth Rehabilitation: Understanding Tooth Wear Treatment Full Mouth Rehabilitation: Understanding Tooth Wear Treatment https://www.youtube-nocookie.com/embed/MvMyH-jqK24 2025-02-04T00:00:00.000Z yes https://hkdentalguide.com/blog/crown-failure-warning-signs-hk https://i.ytimg.com/vi/MIJd0UIiH-M/hqdefault.jpg 牙套與牙橋失敗案例解析 牙套與牙橋失敗案例解析 https://www.youtube-nocookie.com/embed/MIJd0UIiH-M 2024-11-12T00:00:00.000Z yes https://hkdentalguide.com/en/blog/crown-failure-warning-signs-hk https://i.ytimg.com/vi/DHtmaNSsNQk/hqdefault.jpg Crown and Bridge Failures Explained Crown and Bridge Failures Explained https://www.youtube-nocookie.com/embed/DHtmaNSsNQk 2024-11-12T00:00:00.000Z yes https://hkdentalguide.com/blog/implant-loose-peri-implantitis-hk https://i.ytimg.com/vi/aRco5mHvy1w/hqdefault.jpg 植牙成功與失敗案例討論 植牙成功與失敗案例討論 https://www.youtube-nocookie.com/embed/aRco5mHvy1w 2025-01-08T00:00:00.000Z yes https://hkdentalguide.com/blog/dental-scaling-hk-price-guide-2026 https://i.ytimg.com/vi/hYrOQZWc6gI/hqdefault.jpg 洗牙會唔會好痛？｜陳思昕醫生拆解牙周病與牙齒敏感迷思 洗牙會唔會好痛？｜陳思昕醫生拆解牙周病與牙齒敏感迷思 https://www.youtube-nocookie.com/embed/hYrOQZWc6gI 2025-01-09T00:00:00.000Z yes https://hkdentalguide.com/en/blog/dental-scaling-hk-price-guide-2026 https://i.ytimg.com/vi/jkh59nARyXs/hqdefault.jpg Is Teeth Cleaning Painful Let’s Break the Myth!
