Debidebi Debiru Goes From Sweet Potato Ice Cream to an Hour of Dental Advice

NIJISANJI — Debidebi Debiru, a Nijisanji streamer, turned a stream about eating ice cream into a long conversation about oral care on Thursday. The stream, titled as a session of beneficial mouth care while eating a rich sweet potato Häagen-Dazs, ran 52 minutes.

Debiru opened the tub within the first minute and said the flavor, topped with a thick, gooey layer, really did taste intensely of sweet potato. Over the next few minutes the streamer compared it to sweet potato pudding, with notes of custard, caramel and sweet potato candy, and said sweet potato pudding was the closest match. Debiru also said a pumpkin flavor was waiting to be eaten afterward.

A mention of a cracked tooth led into dental topics: whether teeth could ever be regenerated, why losing teeth seems to wear people down, and whether fluoride toothpaste should be rinsed off. Debiru read out viewers’ answers on how many times they rinse after brushing, and the numbers ranged from one to five. A long exchange on dental floss versus interdental brushes followed, in which Debiru doubted that daily bleeding gums could be good, then noted that medical ideas change by era and brought up the old practice of bloodletting.

Viewers filled the comments with product suggestions, including pre-brushing rinses, a medicated paste, an electric toothbrush and a water-jet cleaner. Debiru, who said they dislike foam and the feeling of brushing, said the water-based device sounded like something they might try. Debiru was surprised at how much the commenters knew about teeth, then put up a poll on oral habits and said the response was larger than expected. Debiru said they did not know how the stream had ended up there.

Near the close Debiru said everyone had learned a lot, and urged viewers who had gone years without seeing a dentist to book a visit.
