When instructing a client beginning phenytoin therapy, what oral hygiene practice should be emphasized?

The emphasis on brushing the teeth and gums three times daily is particularly important for clients beginning phenytoin therapy because one of the common side effects of this medication is gingival hyperplasia, which is the overgrowth of gum tissue. This increased gum tissue can make oral hygiene more challenging and could lead to a higher risk of plaque accumulation and periodontal disease.

By brushing three times daily, individuals can help minimize plaque buildup, maintain better gum health, and potentially reduce the severity of gingival changes associated with the medication. Additionally, this practice promotes overall oral health, which can be crucial in managing the side effects of phenytoin and preventing further complications.

While rinsing with mouthwash, brushing once daily, or flossing after meals are all beneficial practices, they do not provide the same level of proactive care required to address the specific risks associated with phenytoin therapy. Hence, the recommendation for brushing three times daily is a focused strategy to mitigate the adverse oral effects linked to this medication.
