Sir, - I was entirely fascinated to read Prof Brian McNichol's letter in praise of toothpicks (January 15th). I could not agree with him more. Where floss (so inapt a name for such a wiry, tough thread) slips and shreds, the toothpick may easily travel, removing with a simple twist of the fingers the harmful and unsightly bacteria.
On a trip to Africa in 1952, my late husband and I were fascinated to observe a small bird walking with impunity in the open mouth of a crocodile while feeding itself on scraps lodged between its teeth. This tiny sparrow is known as the dentist bird, and the locals, taking sensible advantage of a natural resource, use its beak to clean their own teeth.
Taking a lesson from the excellent dental work of the people, I purchased a handful and still use them today. I am 92 and still have all my own teeth. - Is mise,
