The video shows a close-up of a person's mouth with their teeth visible. The teeth are covered in a red substance, and a dental tool is being used to scrape it off. The tool is being moved along the teeth, removing the red substance. The person's lips are slightly parted, and the teeth are white with some visible stains. The red substance appears to be a gel or paste, and the dental tool is metallic and sharp. The video is shot in a well-lit room, and the focus is on the teeth and the tool.
