Here is a good example of gingival overgrowth caused by a calcium channel blocker our patient is taking. These blockers are commonly used to reduce blood pressure. Overgrowth of the gums is a common side effect and requires the patient to have excellent oral hygiene and frequent checkups and cleanings. It is important to have strict caries control and to correct any defective restorations as the gums will want to grown into any open space and almost look like it is engulfing the tooth! The patient above has some natural spaces between some of his front teeth. See how the gums just want to grow into and occupy the space. Sometimes surgical excision is required or consultation with your physician to discuss an alternate therapy.
