Toothache at night: why it gets worse and what helps

Why a toothache feels worse at night, simple things that can ease it until morning, and the signs that mean you should not wait.

A toothache that you can ignore in the day often becomes hard to bear at night. You are not imagining it, and there are a few safe things you can do until you see a dentist.

Why is it worse at night?

There is no single proven reason, but two things probably play a part. When you lie flat, more blood flows to your head, which can add pressure to an inflamed tooth. And at night there is nothing else to take your mind off the pain.

What can help until morning?

Sleep with your head raised on an extra pillow.
Rinse gently with warm water with a little salt.
Brush the area gently and clear any food stuck between the teeth, using floss with care.
Hold a cold pack, wrapped in cloth, on the outside of your cheek for a few minutes at a time.
Avoid very hot, cold or sweet food and drink before bed, and chew on the other side.

What about pain medicine?

Ask a doctor or pharmacist which pain medicine is safe for you, especially if you are pregnant, have another health condition or take other medicines. Follow the dose on the pack. Do not put a tablet on the gum or tooth. It can burn the gum.

What should you not do?

Do not put anything strong on the tooth, such as alcohol or tobacco powder.
Do not cancel your visit because the pain has eased by morning. Pain that comes and goes still has a cause. See what to do before your appointment.

When you should not wait until morning

Get help the same day, or go to a hospital emergency department, if:

swelling spreads to your face, eye or neck
you have a fever with the toothache
it is hard to swallow, breathe or open your mouth

These can be signs of a spreading infection. Read tooth abscess: signs and treatment and dental emergency: when to go today.

When to see a dentist

See a dentist as soon as you can, even if the pain goes away. A cavity or an infection does not heal by itself. See signs of a cavity.
