It’s 10 p.m. on a Tuesday. You’re winding down for the night when you feel it. A dull throb in your back tooth. Nothing sharp. Nothing urgent. Just a little toothache. You tell yourself it’ll probably go away by morning. You take some ibuprofen and try to sleep.
But a few hours later, you’re wide awake. That dull throb is now a pounding ache that radiates up to your ear. Your pillow feels warm. Your jaw hurts when you close your mouth. Now you’re staring at the ceiling wondering: should I have called someone?
Let’s answer that question honestly so you know what to do when it happens to you.

The Short Answer
Most toothaches can wait until morning. But some absolutely cannot.
The tricky part is telling the difference. Because a toothache that starts mild can turn serious fast. And by the time you’re sure it’s an emergency, you might be stuck waiting until the office opens anyway.
Here’s a simple rule we use at our Carol Stream office. If you can control the pain with over-the-counter medication and still function, it can probably wait. If the pain is so bad you can’t think straight, you’re running a fever, or your face is swelling, that’s not a wait-until-morning situation.
When to Actually Call an Emergency Number
Let’s be clear about what counts as a dental emergency.
Call immediately if you have:
- Swelling in your jaw, cheek, or under your eye. That swelling can spread to your airway if it gets bad enough.
- A fever along with the tooth pain. That means the infection may be spreading beyond the tooth.
- Trouble breathing or swallowing. This is rare, but it’s serious. Go to an emergency room.
- Bleeding that won’t stop after a tooth extraction or injury.
For everything else, you can probably make it until morning.
What’s Actually Happening Inside Your Tooth
To understand why toothaches hurt so much, you need to know a little about what’s inside your tooth.
Right in the center is the pulp. That’s where the nerves and blood vessels live. When a cavity gets deep enough to reach that pulp, or when a crack lets bacteria inside, the pulp gets angry. It swells. But here’s the problem. The pulp is trapped inside a hard shell of enamel and dentin. There’s nowhere for the swelling to go.
So pressure builds. And pressure on nerves equals pain. Lots of it.
That’s why toothaches often feel worse when you lie down. Blood rushes to your head, increasing the pressure in that already-cramped space inside your tooth.
What to Do Right Now (While You Wait)
If you decide to wait until morning, here’s how to make yourself as comfortable as possible.
- Take an over-the-counter anti-inflammatory like ibuprofen. It reduces swelling, which reduces pressure, which reduces pain. Avoid aspirin if you might need any dental work soon, because it thins your blood.
- Sleep with your head propped up on two pillows. Gravity helps keep blood from pooling in your head.
- Rinse gently with warm salt water. Don’t swish hard. Just let it wash over the sore area to clear out any food debris.
- Do not put aspirin directly on your gum. That’s an old wives’ tale, and it actually burns your gum tissue. Do not use heat on your face. Heat draws more blood to the area and can make swelling worse. Use a cold pack wrapped in a towel instead.
- Avoid anything very hot, very cold, or very sugary. Those will irritate an already angry tooth.
What Happens When You Call Us in the Morning
When our Carol Stream office opens, call us first thing. Tell the person on the phone exactly what happened, when the pain started, and whether you’ve had any swelling or fever.
We’ll get you in as soon as we can. Sometimes that means squeezing you in between other appointments. Sometimes that means the same day. We know tooth pain is miserable, and we don’t make you wait longer than necessary.
Once we see you, we’ll take an X-ray to figure out what’s going on. Maybe it’s a deep cavity that needs a root canal. Maybe it’s a chipped tooth that needs a crown. Maybe it’s something as simple as a piece of popcorn stuck in your gum.
Whatever it is, we’ll give you a plan.

We’ll take care of you. That’s what neighbors do.
