Colgate, but sometimes..just to be different I will switch to Mentadent or Crest. Seriously, people think my user name 'the brod' is a slang term for a woman, but it is actually after my late dog Brody...who my husband and I always called 'thebrod'...he is no longer with us and his life was cut short by lymphoma, but we had 10 wonderful years with him...and he will always be in my heart...the pic of the dog above is my current dog Jake...a Curly Coated Retriever...and a wonderful dog...
