White bumps on a newborn’s gums or palate can be developmental oral cysts. A pediatric dentist can identify the finding; appearance alone is not enough for a diagnosis.
What are newborn oral cysts?
AAPD describes these as tiny, smooth, whitish bumps containing keratin. They usually measure 1–3 millimeters and cause no symptoms.
Epstein pearls
These occur along the middle of the roof of the mouth.
Bohn’s nodules
These can appear near the junction of the hard and soft palate or along the sides of the gum ridges.
Dental lamina cysts
These occur on the tops of the gum ridges.
Do they need treatment?
Confirmed developmental cysts generally need no treatment and usually resolve within the first three months of life.
Why have a dentist check?
Other mouth conditions can look similar. AAPD recommends assessing the history, symptoms, and examination findings before deciding on care. Ask your child’s dentist about an unexplained bump or any change in its appearance.
