Toothache in Shepperton: What It Means and When to See a Dentist

Toothache is one of those things people put up with for far too long. A dull ache that flares up when you drink something cold. A sharp jab that comes and goes. A pressure that only starts when you lie down at night. The temptation — for very understandable reasons — is to wait and see whether it settles on its own.

Sometimes it does. More often, it doesn't. And with tooth pain, the underlying cause almost always gets worse, not better, when it's left alone.

Here's a straightforward guide to the most common causes of toothache, how to tell mild from urgent, what to do at home while you're waiting to be seen, and when to book a normal appointment versus pick up the phone right now.

Common Causes of Toothache

Toothache isn't a single condition — it's a symptom, and it can come from several different underlying problems. The character, timing and location of the pain give strong clues to what's actually going on.

1. Tooth decay (cavities)

The classic and most common cause. Bacteria break down the outer enamel and reach the sensitive inner dentine, producing:

• Sensitivity to sweet foods and drinks, and often to cold
• A dull ache when pressure is put on the tooth
• Pain that comes and goes rather than being constant, especially in the earlier stages
• Sometimes a visible dark spot, hole, or roughness on the tooth

Small cavities often produce no symptoms at all, which is exactly why regular check-ups matter. By the time a cavity is causing consistent pain, it's usually already deep.

2. A cracked or fractured tooth

A tooth can crack from a sudden injury, from biting on something hard, or gradually over years from grinding and clenching. Cracks can be hard to see with the naked eye but produce characteristic symptoms:

• Sharp pain on biting down on the affected tooth, particularly when biting on something small or hard
• Pain that eases immediately once the pressure is released
• Cold sensitivity that lingers
• No pain at rest — the tooth only "reveals" itself when it's used

Cracked teeth are one of the trickier diagnoses in dentistry because the pain can be intermittent and hard to pinpoint. Left untreated, cracks generally deepen.

3. Gum infection or gum disease

Pain from the gums rather than the tooth itself can feel just as much like a "toothache":

• A dull, throbbing ache along the gumline
• Tenderness when touching or brushing the affected area
• Bleeding gums
• A bad taste
• Localised swelling

Gum-related pain is often diffuse — it's hard to point to exactly which tooth is affected — and it's often accompanied by other signs of gum disease.

4. A dental abscess

An abscess is a localised bacterial infection, either at the root tip of a tooth (usually caused by untreated decay reaching the nerve) or in the gum pocket beside a tooth (usually caused by advanced gum disease). Symptoms include:

• Severe, continuous throbbing pain that isn't relieved much by over-the-counter painkillers
• A swollen gum or face on the affected side
• The tooth may feel raised or "different" to bite on
• Sensitivity to hot (in particular)
• Sometimes fever, a bad taste, or pus

Abscesses need prompt professional treatment — this is not a wait-and-see situation.

5. A dying or inflamed tooth nerve (pulpitis)

When decay or trauma reaches the tooth's nerve, the nerve becomes inflamed. In its early stages this can be reversible; once it becomes advanced, the nerve dies and the tooth generally needs root canal treatment (or, occasionally, extraction) to save it.

Symptoms include:

• Spontaneous, throbbing pain — pain that comes without any obvious trigger
• Pain that wakes you up at night, or is worse when lying flat
• Pain triggered by hot that lingers for minutes, not seconds
• Later, sometimes a strange easing of pain as the nerve dies, followed by return of pain if an abscess develops

Nerve pain often escalates over days to weeks. Waiting to see if it settles rarely works out well.

6. Sinus-related "toothache"

The roots of your upper back teeth sit very close to the maxillary sinuses. A sinus infection or heavy congestion can cause pressure and pain that genuinely feels like toothache in the upper molars. Clues that the pain might be sinus-related:

• Multiple upper back teeth ache at once, all on the same side
• Pain gets worse when you bend forwards or lie down
• Accompanied by cold or flu symptoms, nasal congestion, or facial pressure
• Teeth are not sensitive to hot or cold on their own

This is worth flagging both to your dentist and, if it persists, to your GP.

Other causes

Less commonly, toothache can be caused by clenching and grinding (bruxism), a wisdom tooth that's partially erupted, food impaction between teeth, or referred pain from the jaw joint (TMJ). A full assessment can distinguish these clearly.

How to Tell Mild Toothache from Urgent Toothache

Not every twinge needs a same-day appointment — but some absolutely do. A rough guide:

Likely fine to book a routine appointment (within the next 1–2 weeks)

• Occasional short-lived sensitivity to cold or sweet foods, which passes within a few seconds
• Mild sensitivity after a recent filling that's gradually settling
• Mild discomfort when eating on one side, without swelling
• Aches that come and go and don't stop you sleeping, eating, or working

These are still worth investigating — the underlying cause often progresses if ignored — but they don't need to be seen today.

Book an urgent appointment (same day or next day)

• Pain that is keeping you awake at night, or waking you from sleep
• Continuous throbbing pain rather than intermittent twinges
• Pain that isn't controlled by over-the-counter painkillers
• Pain triggered by hot that lingers for a long time (rather than easing quickly)
• Pain that has been building over several days rather than settling

Call immediately (999 or A&E if severe)

• Significant facial swelling, especially if it is spreading or affecting your eye or under your jaw
• Difficulty swallowing or breathing associated with facial or throat swelling
• High fever alongside dental pain
• Any combination of the above with feeling generally unwell

The last set is a true medical emergency, not just a dental one. Please don't wait to speak to a dentist in the morning — go to A&E.

For everything short of that, our emergency dentist page explains how urgent dental appointments work at our Shepperton practice.

Home Comfort Measures While You Wait

If you're managing a toothache in the hours or day before you can be seen, the following are safe and often genuinely helpful:

• Over-the-counter painkillers. Ibuprofen (if you can safely take it — check with a pharmacist if unsure) tends to be particularly effective for dental pain because it's an anti-inflammatory. Paracetamol works too, and the two can often be taken together at their recommended doses if one alone isn't enough. Follow the packet instructions.
• A cold compress on the outside of the cheek near the affected area for 10–15 minutes at a time can reduce swelling and pain. Wrap ice in a cloth — don't apply it directly to the skin.
• Rinse gently with warm salt water (half a teaspoon of salt in a glass of warm water) a few times a day. This soothes gum tissue and helps clean the area around the tooth.
• Avoid the trigger. If cold sets it off, avoid cold drinks. If chewing on that side hurts, chew on the other side. This isn't a fix — it's just avoiding making things worse in the meantime.
• Keep your head slightly elevated at night. Pain from an inflamed nerve or abscess is often worse when you lie flat, and a couple of extra pillows can help you sleep.

What not to do

• Don't put aspirin directly onto the gum or tooth. It's an old wives' remedy and it burns the tissue. Swallow painkillers with water as directed.
• Don't apply heat externally if there's any swelling — heat can worsen swelling from infection. Cold is safer.
• Don't ignore a swelling that's spreading, and don't try to lance an abscess yourself. Call the practice, or A&E if it's severe.
• Don't stop halfway through a course of antibiotics if you've been prescribed them, even if the pain settles.

When to Call Us

Same-day call: severe or continuous pain, pain waking you at night, swelling (of any size) around a tooth or on the face, a knocked-out or fractured tooth, pain that isn't being controlled by painkillers.

Routine appointment: intermittent sensitivity, mild ache when eating, discomfort that's been present for a while but is manageable — still worth investigating, just not same-day.

Emergency services (999 or A&E): significant swelling affecting breathing or swallowing, spreading facial swelling, high fever, or a feeling of being seriously unwell alongside dental pain.

Confident Smile in Shepperton is on 01932 227 349 — please call rather than hoping the pain will pass. It very rarely does, and early treatment is almost always simpler, faster and less involved than late treatment.

Frequently Asked Questions

How long is too long to leave a toothache? There's no strict number, but a useful rule of thumb: any toothache that has lasted more than a couple of days, is disturbing sleep, or is not responding to over-the-counter pain relief should be seen without further delay. Pain that has resolved on its own is also worth investigating — sometimes it means the nerve has died rather than the problem having gone away.

Can toothache go away on its own? Occasionally yes — a piece of trapped food, a passing bout of sinus congestion, or a very transient sensitivity can settle without treatment. But the vast majority of persistent toothaches are caused by something that needs professional attention. Absence of pain isn't the same as absence of problem.

Do I need an emergency appointment or a routine one? If pain is disturbing sleep, if there's swelling, or if it isn't controlled by painkillers, treat it as urgent and call. Otherwise, book as soon as you can into a routine slot. If you're unsure, calling the practice for guidance is always the right move — we'd rather advise on the phone than have you sit in pain wondering.

Will I need a root canal or an extraction? Not necessarily. Many toothaches turn out to be from causes that don't need either — a small cavity, a leaky old filling, gum inflammation. Even when the nerve is involved, root canal treatment can often save the tooth. Extraction is a last resort, not a first response.
