How does Lesch–Nyhan syndrome affect dental management?
Team plan: Stepwise, least-invasive-first plan with neurology, caregivers and the medical team
Protection: Behavioral strategies and stress reduction; protective devices (mouthguards, lip bumpers, bite blocks) when tolerated
Specialist option: Botulinum toxin has been described in specialist reports; it is not an established routine dental protocol and requires specialist selection and follow-up
Consider extraction: persistent, severe tissue injury despite a feasible protective plan. Discuss selective or more extensive extraction with the multidisciplinary team and family.
Before deciding: specify the injuring teeth, alternatives tried, expected functional losses, and continuing risk after new teeth erupt. Extraction is irreversible and individualized.
Before treatment or anesthesia: review medications; assess positioning, swallowing, and renal function.
Why these matter: dystonia affects positioning, dysphagia increases aspiration risk, and uric acid nephropathy can impair renal function.
