A newborn has a sharp tooth and tongue ulceration. What guides treatment?
Relieve tooth-related tongue trauma while retaining the tooth when function and stability permit; aspiration risk may justify extraction.
-
Confirm natal/neonatal timing and assess feeding, tongue/nipple injury, mobility, detachment risk, and appliance interference.
-
A safely retained functional tooth may be managed by smoothing the sharp edge; extraction may be needed when mobility or functional harm makes retention unsafe.
-
Appearance alone should not determine removal.
