Dental Education Lecture: Rapidly Loosening Tooth

Sometimes the tooth may become loose in a pretty quick fashion.  This happens to Mrs. Liu.  She came to our office two years ago. We did exam, cleaning and X-ray.  The latter shows that the half of the roots of the bottom front teeth has lost bone support (between two arrowheads in Fig.1).

She returned for cleaning a year later.  We took panoramic X-ray, which shows vaguely that the tooth #26 has lost more bone support (Fig.4).  The blow-up image show bone loss a little bit better (between arrowheads in Fig.2).  Due to dental insurance limitation, we could not take another X-ray in the same day.  We advised her to return for further investigation sooner.

As usual, she returned one year later.  But she had a problem now.  One of the bottom front teeth is loose and tender.  New X-ray shows that the tooth #26 has lost almost all of the bone support (Fig.3).

We need to do root canal, and splinting.  Without immediate attention, the tooth is going to come out itself.
