Is ‘Close Up Whitening' a toothpaste or dental cleaner?

It is only customary to address Seniors as Sir and there is nothing atrocious inn it. But I have seen this going to ludicrous levels . At some innocuous in house meetings I have seen welcome speeches like our respected Commissioner sir Shri......sir was kind enough to come over to this function . Nowadays it is not uncommon to see addressing celebrities as Name suffixed by sir during channel shows . I have never seen anybody saying Gandhi sir or Nehru sir and it never meant disrespect
