Treatment such as irradiation has been shown to have severe effects on developing teeth. In a smaller capacity, chemotherapy was also found to have a similar effect. Thalidomide (N-phthaloylglutamine) was also discovered to have a causative effect on mothers who took the drug during pregnancy, resulting in congenitally missing teeth in their ...
Plaque accumulation causes the gingiva to become irritated and inflamed, and this is referred to as gingivitis. When the gingiva become so irritated that there is a loss of the connective tissue fibers that attach the gums to the teeth and bone that surrounds the tooth, this is known as periodontitis.
Tooth development can be delayed with increasing severity of CLP. Some of the dental problems affect the primary teeth, but most of the problems arise after the permanent teeth erupt. Problems may include fused teeth, missing teeth, and extra teeth erupting behind normal teeth. Missing teeth or extra teeth are both normal occurrences.
Dental attrition is tooth wear caused by tooth to tooth contact. Well-defined wear facets appear on tooth cusps or ridges. This can be caused by several factors, including parafunctional habits such as bruxism or clenching, developmental defects, hard or rough-textured diet, and absence of posterior teeth support.
A case of severe gummy smile as seen in a young woman. Gummy smile, also known as excessive gingival display, is a smile that shows gum under the upper lip. It is a common clinical condition, which can be caused by an abnormal dental eruption (delayed passive eruption), hyperfunction of the upper lip elevator muscle, excessive vertical growth of the maxilla bone, over-eruption of the maxillary ...
Abnormal tooth position, such as tooth crowding, giving inadequate cover of one or more teeth by the jaw bone. [1] Piercings in the lip or tongue that wear away the gum by rubbing against it. [8] [9] Intentional gingival retraction. For example, the adult tooth may not grow out of the gum, and to remedy this, a procedure called an exposure is done.

Tooth gemination occurs when a developing tooth germ splits. The exact cause of tooth gemination is unknown but involves changes in embryonic tooth development. [1] Environmental (e.g. trauma, thalidomide exposure, hypervitaminosis A of the mother, viral infections), systemic, and genetic factors can cause formation of double teeth.
