Some dental problems are medical emergencies. Get emergency care right away if you have:
- Difficulty breathing or swallowing
- Swelling of the face, jaw, floor of the mouth, or neck — especially if it is spreading
- Swelling that affects your eye or makes it hard to open your mouth
- A high fever combined with mouth or facial swelling
- Bleeding that won't stop after 10–15 minutes of firm pressure
- A knocked-out adult tooth, or an injury to the jaw, head, or face
When in doubt, consider it an emergency and seek care now.
Tooth pain at night can be maddening, especially when your dentist’s office is closed. Here are safe, widely recommended ways to manage the pain while you arrange care.
Safe relief steps: what actually works
Cold compress
Apply a cold, damp cloth or ice pack to your cheek (outside the tooth area) for 15 minutes, then take a 15-minute break. Cold reduces inflammation and numbs the pain. Don’t apply ice directly to your skin.
Warm salt-water rinse
Mix 1/2 teaspoon salt in 8 ounces of warm water and rinse gently. Salt water reduces inflammation in the gum and soothes irritation. Repeat every few hours.
Elevation
Sleep with your head propped on 2–3 pillows rather than lying flat. This reduces blood pressure in the tooth and may ease pain.
Gentle flossing
If food is stuck between the teeth, gentle flossing (not aggressive picking) can sometimes release it and ease pain. Be very gentle to avoid irritating the gum further.
Over-the-counter pain relief
An over-the-counter pain reliever may help while you arrange care — ask your pharmacist or dentist what’s appropriate for you, and follow the label directions.
Avoid irritants
Don’t chew on the side with the painful tooth. Avoid very hot, cold, hard, or sticky foods. These can trigger pain or make it worse.
What NOT to do
- Don’t apply heat — heat increases blood flow and can make inflammation worse
- Don’t place pain-reliever tablets directly on the gum — they can burn the soft tissue
- Don’t ignore the pain — pain is a sign that something needs treatment; home care is temporary
Why night pain feels worse
Three things happen at night that make toothache pain feel more intense:
- Blood flow increases to your head when you lie down, raising pressure in the tooth
- Distractions disappear — no work, no activity, so you feel the pain more acutely
- Inflammation peaks — infection and swelling follow a 24-hour cycle and often worsen at night
These are normal, but they mean night pain doesn’t always reflect how severe the underlying problem is.
When to seek emergency care (not wait until morning)
Call an emergency dentist or go to the ER if:
- Pain is so severe you cannot function or sleep at all, despite comfort measures
- You have fever, swelling of your face or jaw, or trouble swallowing
- You have trouble breathing
- Pain started after trauma (a fall, blow, or accident)
Otherwise, use comfort measures and call your dentist’s office first thing in the morning.
What to expect at the dentist
Your dentist will examine the tooth and take X-rays to find the cause. Common causes of night pain include decay, a cracked tooth, an exposed root, a lost filling, or early infection. Treatment depends on the cause, but addressing it is the only way to stop the pain long-term.

Frequently asked questions
Why does tooth pain get worse at night?
When you lie down, blood flows to your head and puts pressure on the tooth, making pain feel worse. Also, daytime distractions are gone, so you notice pain more. Inflammation from decay or infection also tends to peak at night.
Is it okay to take over-the-counter pain medication for tooth pain?
An over-the-counter pain reliever may help alongside the comfort measures below — ask your pharmacist or dentist what's appropriate for you, and follow the label. Keep in mind that medication only masks the pain; the underlying problem still needs treatment.
Should I go to an emergency dentist at night or wait until morning?
If the pain is severe and you can't function, or if you have fever, swelling, or trouble breathing, seek emergency dental or medical care immediately. Otherwise, apply comfort measures and call your dentist first thing in the morning for an urgent appointment.
