I go to the dentist every 6 months for check ups, xrays, cleaning and polish. This is in the US. Normally the prevention stuff is covered by insurance 100%. I will have to pay out of pocket for my next US dental visit this summer, but even at that, I think I was told about £50, which is well worth it. I went awhile without going to the dentist, and when I went in I was horrified, I had to get two fillings, a root canal and a crown--and I was not having pain or problems. Lack of pain or lack of problems does NOT mean your teeth and gums are not having issues. That was such a wake up call that now I get to the dentist like clockwork.
