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 .
