Dr. Maloney is a friendly and intelligent dentist. His laid back approach is soothing, and the no-frills, friendly receptionist is also welcoming. He cleaned my teeth for many years.
During that time, I noticed that one of my teeth had been turning black. Because he is so laid-back, he said it was probably a filling that had discolored the tooth and didn't do any further testing (I had 4 other fillings with no discoloration). When I finally had pain, years later, and got an x-ray, it turned out that my tooth was dead. What's more, the top notch doctor who performed root canal said the tooth had been dead for many, many years.
Dr. Maloney, when confronted, said it was my fault for not wanting to spend money on x-rays (he did plenty of x-rays other times). It turns out that he could have done a free cold test which determines whether the tooth is alive or not. With more modern equipment and a little less laid-backedness, he would be a much better dentist.
