Hello , how are you today . Here for your six month check-up ?   I'm fine , Dr . Beecham . Yes , just a cleaning and check-up today .   Oh , fine . Let's take a look .   ( She probed my teeth and checked my gums . ) Well , it looks like you have a cavity and your crown is loose . We need to fill that cavity before it gets any worse and the crown needs to be refitted . Make an appointment for next week and I'll take care of them .   Okay , I'll do that , but my crown was just put on last year . Will my dental insurance cover the work ?   Since you had that done here , we'll take care of it . There won't be a charge . And , your insurance should cover the work on the cavity . Now , I'm going to have the hygienist do your cleaning and I'll see you soon for the other work .
