Two years ago, I was supposed to get a crown for my upper left first molar. The dentist had already put a post on it. Due to personal problems, I was not able to go back and had the work completed.
Last week, I went to a new dentist to complete the work. He prepped the tooth and made an for the crown. He will use the existing post. When he filed down the tooth, he found a new cavity between the second premolar and the first molar teeth. If these teeth have cavity, is the post in the molar not affected? Is it still stable? Should I ask the dentist to put in a new post? Please shed some light on me about this. Thanks so much.
