Toothache: What to Do Before You See a Dentist

Your tooth starts throbbing on a Friday night, on holiday or the day before a flight, and the earliest dental appointment is a day or two away. It happens to almost everyone. The good news: you can nearly always take the edge off the pain with simple, safe steps. The catch: nothing you do at home treats the cause. An inflamed tooth does not heal by itself. It calms down for a while or moves to the next stage.

So your goal for the next few hours is simple. Bring the pain down, avoid making things worse and know when waiting is no longer an option. Most toothaches can wait until morning or the next working day. Swelling, a fever or pain that painkillers barely touch cannot.

How to stop toothache getting worse right now

Start with the basics. Pain is often kept going by trapped food, a cold drink or chewing on the sore side. While you wait for an appointment, the NHS suggests a few steps:

• Brush gently with a soft toothbrush and rinse with warm water to clear any food. Skip flossing around the sore tooth for now.
• Take a painkiller you already have at home, exactly as the label says. Not sure which one suits you? Ask a pharmacist.
• Eat soft food at room temperature and chew on the other side.
• Avoid sweet, very hot and very cold food and drinks. Put off smoking too. The NHS says it can make some dental problems worse.
• Use an extra pillow at night. Many people find throbbing pain feels stronger when they lie flat.

A painkiller buys you time. It does not replace treatment. If each tablet works less well and the gaps between flare-ups get shorter, the inflammation is spreading. That is your cue to call a dentist, not to take more tablets.

Best pain relief for toothache: what to ask the pharmacist

Standard over-the-counter painkillers are what most people use for tooth pain. The right choice for you depends on your age, any long-term conditions, other medicines you take and pregnancy. Keep the question simple: which painkiller is safe for me, with my health and my medicines? Never go over the dose on the label and do not mix products on your own. Antibiotics are a different story. Only a doctor or dentist can prescribe them.

Home remedies for toothache that actually help

The simplest and safest option is a warm salt-water rinse. The NHS recommends dissolving half a teaspoon of salt in a glass of warm water, rinsing your mouth and spitting it out without swallowing. You can repeat it as often as you like. Salt eases gum swelling a little and cleans the area around the tooth, and warm water will not trigger a new jolt of pain the way ice-cold water does.

One rule applies to any rinse. Keep it warm, never hot. Hot liquid sends more blood to the inflamed area and the pain comes back harder after a brief moment of relief.

What not to do

Some old tips get passed down for generations even though they do more harm than good. Never press a tablet or a clove of garlic against your gum. It can cause a chemical burn on the soft tissue, and the pain inside the tooth stays exactly the same. Rinsing with spirits irritates your gums too and numbs nothing.

A hot water bottle or a warm compress on your cheek is risky if you suspect a pus-filled infection. Heat increases blood flow and can make the infection worse. If your cheek is already swollen, use only a cool compress wrapped in a cloth, for short spells. One more thing. Do not try to pop a lump on your gum or pick at a hole in your tooth with a needle. That is a quick way to spread infection.

At night and at weekends: getting through a flare-up

Tooth pain often feels worse at night, and tiredness is only part of it. During the day you are busy. In a quiet room you feel every throb. Prepare in the evening: brush, rinse with salt water, take a painkiller as the label says and sleep with your head raised.

Wondering what helps toothache that wakes you up at 3am? Rinse again with warm water and think about what set it off. A short twinge after a cold drink that fades fast can usually wait for a routine appointment. Constant, building, throbbing pain that a tablet barely touches cannot wait until Monday. Call a clinic first thing in the morning. If you also have swelling or a temperature, follow the urgent care advice below.

Why your tooth hurts: common causes

According to the MSD Manual, the most common cause is tooth decay and what follows it: inflammation of the pulp (the nerve inside the tooth) and an abscess at the root. Injuries and an erupting wisdom tooth are also on the list. The way a tooth hurts tells the dentist a lot. Notice when and how the pain shows up.

If your tooth hurts when you press on it but barely reacts to cold, the inflammation has often moved beyond the nerve into the tissue around the root. This is not pain to sit on for a week. You need an X-ray, and in most cases root canal treatment can save the tooth.

When the pain suddenly stops

Plenty of people cancel their appointment with relief once the pain fades. Yet the MSD Manual describes exactly this pattern. Inflamed pulp often dies, and the pain goes away for a while, anywhere from a few hours to a few weeks. Then it comes back, this time from inflammation around the root or an abscess. A quiet tooth after severe pain does not mean it has healed.

Wisdom tooth pain

Wisdom teeth often come through only partly and leave a flap of gum where bacteria build up. The result is a dull ache at the very back of the jaw, a bad taste and trouble opening your mouth. The same home care helps: warm salt-water rinses, careful but gentle brushing and chewing on the other side. If the pain keeps coming back, a dentist will check the tooth's position on an X-ray and tell you whether it can stay or whether wisdom tooth extraction is the safer choice.

Pain after a filling

Mild sensitivity to cold for a few days after a deep filling is common and usually settles on its own. Pain that gets stronger instead of weaker, starts for no reason or keeps you awake is a different matter. It can happen when the nerve was already inflamed before treatment. Another common cause is simple: the filling sits slightly higher than the teeth next to it and the tooth takes extra pressure every time you bite. A dentist fixes that in minutes. No need to put up with it.

When to see a dentist urgently

The NHS advises seeing a dentist if your pain lasts more than 2 days or does not go away with painkillers. The same goes for pain that comes with a high temperature, pain when you bite, red gums or a bad taste in your mouth. Some situations cannot wait even an hour. Use this table as a quick guide.

Swelling with a fever means the infection may have spread beyond the tooth. You can read more about these complications in our article on tooth abscess. One more point worth knowing. MedlinePlus, the US medical encyclopedia, notes that tooth and jaw pain is sometimes referred pain and can even come with a heart attack. If jaw pain arrives together with chest pressure, shortness of breath or a cold sweat, call an ambulance, not a dentist.

What happens at the dental appointment

The dentist will ask when the pain started, what triggers it and whether it wakes you at night. Then they check the tooth and gum and test how the tooth reacts to cold and tapping. You will almost always need an X-ray, because only an image shows what is going on inside the tooth and around the root. After that the dentist can tell you if a filling is enough, if the root canals need treatment or if the tooth cannot be saved.
