Sudden tooth pain at night can feel worse than the same pain during the day. It is quiet, you are alone, and the dentist's office is closed. The good news is that there are safe things you can do at home to calm the pain until you can get care.
This guide walks you through what to do right away, what to avoid, and how to tell when the pain needs urgent attention.
Quick Answer
If a tooth starts hurting at night, rinse your mouth with warm salt water, gently remove any food stuck between your teeth, and hold a cold compress against your cheek. Keep your head raised, and take an over-the-counter pain reliever only as directed on the label. Then contact a dentist as soon as you can, because home care only calms the pain. It does not fix the cause. Go to an emergency room if you have facial swelling, a fever, or trouble breathing or swallowing.
Why Does Tooth Pain Feel Worse at Night?
Many people notice that a mild toothache turns into a throbbing one after they lie down. There are a few reasons:
- Blood flow to the head increases. When you lie flat, more blood flows to your head, which can add pressure to an inflamed tooth.
- You have fewer distractions. During the day, work and activity keep your mind busy. At night, the pain is all you notice.
- You may clench or grind your teeth in your sleep. This can irritate a sore or cracked tooth.
The pain is not "in your head." It is often a sign that something in or around the tooth needs attention.
Steps to Take Right Away
1. Rinse With Warm Salt Water
Mix half a teaspoon of salt in a glass of warm water. Swish gently for about 30 seconds, then spit. This can loosen food debris and calm irritated gums. Do not swallow the rinse.
2. Clean Between the Teeth Gently
Food stuck between teeth is a common cause of sudden pain, especially if the tooth is next to a cavity or a gap. Use dental floss slowly and gently. Do not use sharp objects such as a pin or toothpick, since they can hurt your gums and make the problem worse.
3. Use a Cold Compress
Wrap a cold pack or ice in a thin towel and hold it against your cheek near the sore tooth for about 15 to 20 minutes. Then take a break. Cold can help reduce swelling and dull the pain. Do not place ice directly on your tooth or gums.
4. Keep Your Head Elevated
Prop yourself up with an extra pillow or two. Keeping your head above your heart may reduce the throbbing that comes from lying flat.
5. Take an Over-the-Counter Pain Reliever Carefully
Common options include ibuprofen or acetaminophen. Follow the instructions on the label, and do not take more than the recommended dose. If you have a medical condition, take blood thinners, are pregnant, or are unsure what is safe for you, check with a pharmacist or your doctor first. Do not give aspirin to children.
Never place aspirin directly on your gums or tooth. It can burn the soft tissue in your mouth.
6. Avoid Triggers
Stay away from very hot, very cold, sugary, or hard foods and drinks until the tooth has been checked. If chewing hurts, avoid using that side of your mouth. Skip alcohol and tobacco too, since both can irritate the area.
7. Consider Learning What Severe Pain Signals
If the pain is intense, constant, or keeps you awake even after these steps, it may need same-day attention. Our guide to severe toothache relief explains what to do next and when to call for urgent care.
Common Causes of Sudden Tooth Pain
Knowing the possible cause can help you describe the problem to your dentist. Sudden tooth pain may come from:
- A cavity. Decay that reaches the inner layer of the tooth can cause sharp or throbbing pain.
- A cracked or broken tooth. Pain may be worse when you bite down or when the tooth touches hot or cold foods.
- A tooth infection or abscess. This is a pocket of infection near the root. It can cause severe pain, swelling, a bad taste, or a bump on the gum.
- A lost or damaged filling or crown. This can expose sensitive layers of the tooth.
- Gum disease or an irritated gum. Swollen, tender gums can make nearby teeth hurt.
- A wisdom tooth problem. A partly erupted wisdom tooth can trap bacteria and cause pain and swelling at the back of the mouth.
- Teeth grinding. Clenching can leave teeth and jaw muscles sore, especially in the morning.
- A sinus problem. Sinus pressure can make the upper back teeth ache.
Only a dental exam can tell you which one it is. Pain can also come and go, or suddenly stop, without the underlying problem being gone.
What Not to Do
When you are in pain and it is late, it is tempting to try quick fixes. A few common ones can do more harm than good:
- Do not put heat on your face. If there is an infection, heat may make swelling worse. Use a cold compress instead.
- Do not place aspirin, alcohol, or other substances on the gum. They can irritate or burn the tissue.
- Do not try to pull, cut, or drain a tooth or swelling yourself. This can spread infection and cause more damage.
- Do not use leftover antibiotics. They may not be the right medicine, dose, or length of treatment, and they can hide symptoms without treating the cause.
- Do not ignore pain that suddenly stops. If a very painful tooth stops hurting, the nerve inside may have died. The infection can still be there.
When Tooth Pain Is an Emergency
Most toothaches need a dentist, not an emergency room. But some signs mean you should get medical help right away. Go to an emergency room or call 911 if you have:
- Swelling in your face, jaw, or neck that is spreading
- Trouble breathing or swallowing
- Swelling that affects your eye or makes it hard to open your mouth
- A fever along with tooth pain and swelling
- Pain after an injury to your face or jaw
- Bleeding that will not stop
An infection in the mouth can sometimes spread, so these symptoms should not wait until morning.
When to Call a Dentist
Call a dentist as soon as you can if:
- The pain lasts more than a day or two
- The pain is severe, throbbing, or wakes you up
- You have a bad taste, a bump on your gum, or pus
- Your tooth is cracked, chipped, or broken
- Biting or chewing causes sharp pain
- The pain keeps returning after it eases
If you are unsure, it is better to call. A dental office can help you decide how urgent your situation is. Many offices, including ours, have an emergency line you can call if the pain begins after hours, and the team can tell you what to do next.
What to Expect at an Emergency Dental Visit
Knowing what happens can make the visit less stressful. A dentist will usually:
- Ask about your symptoms, when the pain started, and your medical history.
- Examine the tooth, gums, and surrounding area.
- Take X-rays if needed to see the roots and the bone.
- Explain what is causing the pain and go over treatment options.
Treatment depends on the cause. It may involve removing decay, repairing or replacing a filling, treating an infection, or, in some cases, a root canal or an extraction. The first goal is to relieve your pain and stop the problem from getting worse. Tell the dentist about all medications you take and any heart conditions or allergies, because this can affect your care.
How to Lower the Chance of Nighttime Tooth Pain
You cannot prevent every dental emergency, but healthy habits reduce the risk:
- Brush twice a day with fluoride toothpaste.
- Clean between your teeth daily with floss or another interdental cleaner.
- See your dentist regularly for exams and cleanings so small problems are found early.
- Limit sugary snacks and drinks, especially before bed.
- Do not chew ice, hard candy, or pens. These can crack teeth.
- Ask about a night guard if you grind or clench your teeth.
- Do not put off small problems. A small cavity or a loose filling is easier to treat than a painful infection.
Frequently Asked Questions
Can I wait until morning for a toothache?
Often, yes, if the pain is manageable and you have no swelling, fever, or trouble breathing. Use the home steps above, and call a dentist when the office opens. If the pain is severe or you notice any emergency signs, do not wait.
What can I take for tooth pain at night?
Over-the-counter pain relievers such as ibuprofen or acetaminophen may help when used as directed on the label. Check with a pharmacist or doctor first if you have health conditions or take other medicines.
Will tooth pain go away on its own?
Sometimes the pain eases for a while, but the cause usually remains. A cavity, crack, or infection will not heal by itself, so it is important to have the tooth checked.
Is a toothache with swelling serious?
It can be. Swelling can be a sign of infection. If the swelling is spreading, affects your breathing or swallowing, or comes with a fever, seek emergency care right away.
