The deep cleaning appointment with hygienist Charlotte Bond costs £125 for half an hour. During this time, Charlotte spent 10 minutes poking the teeth and gums, another 10 minutes administering anesthetic shots, and attempting to sell an electric toothbrush. The actual cleaning took only 10 minutes and covered just half of the mouth. To clean the entire mouth, we need to schedule another half-hour appointment at an additional cost of £125. This means that the total cost for teeth cleaning alone would be £250. Additionally, please note that without completing this procedure, Hyslop will not allow me to join their regular monthly payment plan. I wanted to make you aware of this before you consider becoming their new client.
