I don't mind having dental work done, but I think my dentist is taking advantage of our new dental insurance. (We've only been seeing him for 3 years.) How can the 5 adults in our family all have cavities, when they've been getting regular cleanings and there have been no diet changes. He also seems to salivate every time he looks at my old silver fillings, wanting to replace them all. Second opinions are a joke. One dentist told my daughter that she had 6 cavities, not 3 that the original dentist reported finding. My second opinion, from a third dentist, reported a cavity between two different teeth. He also saw no "hairline" fractures in my old fillings, like my original dentist was seeing. That dentist said, "You will get 10 different opinions from 10 different dentists." I would follow it up by saying, "Yes, but every one of them will find something that they think needs to be done."
