Child Has Tooth Pain at Night? Causes & What to Do

Tooth pain at night is one of the most common reasons parents call us at Little Angels. The pain often feels worse after lights-out — and there's a real reason for that.

Why does tooth pain get worse at night?

When your child lies down, more blood flows to the head. That extra pressure pushes against an already-inflamed nerve inside the tooth, intensifying the throbbing. There are also fewer distractions at night, so the pain feels sharper.

Common causes

• Cavity reaching the nerve — most common cause
• Dental abscess — pus collection, often with swelling
• Erupting tooth — especially 6-year molars or wisdom teeth
• Food trapped between teeth — sudden, sharp pain
• Cracked tooth from injury

What to do tonight (home steps)

• Rinse the mouth with warm salt water.
• Gently floss to remove any trapped food.
• Cold compress on the cheek (15 min on, 15 off).
• Pediatric paracetamol or ibuprofen — correct dose for weight.
• Sleep with the head slightly elevated.
• Do not put aspirin or clove oil directly on the gum — it burns child tissue.

When to call a dentist immediately

Call us right away if there's facial swelling, fever, pain that doesn't reduce with medicine, or pain after a fall. These need urgent emergency dental care.

For non-emergencies, book a same-week appointment so the underlying cause — usually a cavity needing a filling or pulp therapy — can be treated before it gets worse.
