My husband had his teeth cleaned in mid January. He was supposed to have another one at least a couple of months ago, yet the dental office kept posponed due to their computer problem and building flood for 3 times.
Thus, he went to a new dental office. This new one found 6 cavities, which were never mentioned back in January when he had the annual x-rays. He brushed 3 times and flossed twice daily. He always had to brush and floss right after eating the breakfast, to go to work. He swished after his lunch first, waited 5-10 minutes, and then brushed. After supper at home, he tended to be relaxed and lazy and did not brush or floss until bed time.
Within these 8 months between the cleaning in January and early October, how could his teeth developed cavities so quickly and so much?
Is there a standardized way to determine a cavity Amon the majority of dentists? Or even if there is a tiny black spot on a tooth, then it's called cavity?
Thanks in advanced for clarifying this.
