Have you been cleaning your teeth?   Does it feel like a different brush each time you use it?
assistant
yes i have. no it does not feel different.
user
Can I check what you’re using?  I’ll just ask you to open the app.  I’ll see a picture of your teethbrush and some information.
assistant
no i just want to know how often to change my toothbrush.

That is a good question.   I have just taken a peek at your toothbrush, and it says that you need to replace it every three months.  Does that help?
assistant
