Tooth surface loss
Tooth surface loss, primarily through acid-induced erosion, may be seen if there has been nausea and associated repeated vomiting during pregnancy. The palatal surfaces of the upper incisors and canines are often the most affected. The woman commonly presents complaining of sensitivity, which is a consequence of the resulting dentine exposure. Management is essentially preventative and includes the regular use of a fluoride mouth rinse, especially in those women who vomit frequently. In addition, these women should be advised to avoid tooth brushing directly after vomiting as the effect of erosion can be exacerbated by brushing an already demineralised tooth surface. Consumption of acidic fruits and juices as well as carbonated drinks should be restricted to avoid the potential for contact between additional acids and the tooth tissues. The use of drinking straws is recommended for the same reason, as is breaking the habit of holding such acidic drinks in the mouth for a longer time than is necessary.
Tooth mobility
Increased tooth mobility has been detected in pregnancy even in periodontally healthy women. The upper incisors are most mobile during the last month of pregnancy. Development of such mobility is possibly due to mineral shifts in the lamina dura and not to modification of the alveolar bone. The degree of periodontal disease present and disturbance of the supporting attachment tissues are also thought to contribute to this mobility, which usually resolves post delivery.
