Dental Education Lecture: Food Traps after Filling

Mrs. Zeng complains that food is trapped between two of her back teeth after two silver fillings (Fig.1 F), causing a lot of discomfort and inconvenience.  For example, gums bleed when she flosses in that area.  X-ray shows that one of the fillings (on your left-hand side) has a large extra portion (arrowhead in Fig.1) and that the other filling has a smaller extra portion.  Fig.2 outlines the extra portions.

To solve the problems, we remove the old filling on the left, trim the the smaller extra portion off the filling on the right and finally place a new white filling on the left (Fig.3).  There has been no food impaction since the retreatment.  We also replace two of her two missing front teeth (Fig.4) with implants (Fig. 5: I: implant, A: abutment, C: crown).
