Every week a Guardian Money reader submits a question, and it's up to you to help him or her out – a selection of the best answers will appear in next Saturday's paper.
This week's question
My dentist is good, but every time I go he's always very keen to book me in to see the hygienist – at £45 a pop. Won't an electric toothbrush and a roll of dental floss do the job just as well?
He's also tried flogging me insurance, but so far I've resisted. Is it a rip-off?
What are your thoughts?
