Toothache vs. Sensitivity: How to Tell if You Need an Emergency Dentist

We have all been there: you take a sip of a hot cup of tea or bite into a cold ice cream, and suddenly, a sharp twinge of pain shoots through your mouth. Or perhaps you wake up in the middle of the night with a dull, constant throb in your jaw that simply will not go away.
When dental discomfort strikes, it can be highly distressing. One of the most common questions our patients ask is how to tell the difference between a minor, temporary issue and a genuine dental emergency. Is it just sensitivity, or do you need to see an emergency dentist immediately?
Understanding the difference between tooth sensitivity and a true toothache is crucial. Not only does it help you manage your symptoms effectively at home, but it also ensures you seek the right level of professional care when you need it most. Here is our guide to understanding your dental pain and knowing when it is time to call The Dental Surgeries.
What is Tooth Sensitivity?
Tooth sensitivity (dentine hypersensitivity) is incredibly common and usually presents as a sudden, sharp, and fleeting pain. The defining characteristic of sensitivity is that the pain is almost always triggered by an external stimulus and subsides very quickly once that stimulus is removed.
Common triggers for sensitive teeth include:
- Consuming hot or cold foods and drinks.
- Eating sweet or highly acidic foods.
- Breathing in cold air.
- Brushing or flossing your teeth.
Why Does Sensitivity Happen?
Your teeth are protected by a hard outer layer called enamel. Beneath the enamel lies the dentine, a softer tissue that contains thousands of microscopic fluid-filled tubes leading directly to the tooth’s central nerve (the pulp). If your enamel becomes worn down, or if your gums recede and expose the root of the tooth (which does not have an enamel covering), these tubes are left unprotected. When temperature changes hit the exposed dentine, the fluid inside the tubes moves, stimulating the nerve and causing that familiar, sharp zap of pain.
Do you need an emergency dentist for sensitivity? Generally, no. If the pain vanishes within a few seconds of removing the hot or cold trigger, it is rarely an emergency. However, you should not ignore it. Mention it at your next routine check-up. Your dentist can recommend desensitising toothpaste, apply fluoride varnishes, or check for early signs of enamel wear and gum disease.
What is a True Toothache?
Unlike the fleeting zap of sensitivity, a true toothache is usually persistent, lingering, and much more severe. It often occurs spontaneously, without any obvious trigger like hot or cold food, and can range from a dull, continuous ache to an excruciating, throbbing pain that radiates up into your jaw, ear, or head.
A toothache is your body’s warning system. It indicates that the living tissue inside the tooth (the pulp) or the tissues surrounding the tooth are inflamed, infected, or damaged.
Common causes of a severe toothache include:
- Deep Tooth Decay: A cavity that has progressed through the enamel and dentine to reach the nerve.
- A Dental Abscess: A localised collection of pus caused by a bacterial infection, often at the root of the tooth.
- A Cracked or Broken Tooth: Trauma or biting down on something hard can fracture a tooth, exposing the sensitive inner layers.
- Failed Dental Work: A lost filling or a loose crown can leave the underlying tooth structure vulnerable.
If the pain is keeping you awake at night, preventing you from eating, or making it difficult to concentrate on your daily tasks, you are dealing with a toothache that requires professional attention.
Red Flag Symptoms: When to See an Emergency Dentist
While some mild toothaches can wait a few days for a routine appointment, certain symptoms demand immediate intervention. Delaying treatment can allow infections to spread or result in the loss of a tooth that could otherwise have been saved. As we have discussed in a previous post about Why You Shouldn’t Ignore a Dental Emergency, ignoring these warning signs can have serious consequences for your health and comfort.
You need to contact an emergency dentist in Bury if you experience any of the following “red flag” symptoms:
- Facial Swelling: Swelling in your face, cheek, or jaw is a clear sign of a spreading infection. If the swelling affects your ability to swallow or breathe, or if it travels towards your eye, you must seek urgent medical attention.
- A Dental Abscess: Look out for a pimple-like bump on your gums, a foul taste in your mouth, or pus oozing from around the tooth. Abscesses will not heal on their own and require professional drainage and antibiotics.
- Severe, Unmanageable Pain: If over-the-counter painkillers like paracetamol or ibuprofen are not touching the pain, do not suffer in silence.
- Trauma or Broken Teeth: If you have had an accident and knocked a tooth loose, chipped it severely, or knocked it out entirely, time is of the essence. Depending on the damage, we may be able to stabilise the tooth or restore it. For long-term restoration of broken teeth, we offer several options, which you can read more about in our guide to Composite Bonding vs. Porcelain Veneers.
What to Do While Waiting for Your Appointment
If you have established that you need an emergency appointment, your primary goal is to keep yourself comfortable until you can get to our clinic.
- Rinse with Warm Salt Water: Mix a teaspoon of salt into a glass of warm (not hot) water and gently swish it around your mouth. This helps to clean the area, draw out fluid from infected tissues, and reduce inflammation.
- Use a Cold Compress: If you have swelling, apply a cold compress or an ice pack wrapped in a towel to the outside of your cheek for 15 minutes at a time. This will help numb the area and bring down the swelling.
- Take Over-the-Counter Pain Relief: Take paracetamol or ibuprofen as directed on the packaging to manage the pain. Never place a painkiller directly against the gum near the aching tooth, as this can cause a severe chemical burn to the soft tissues.
- Avoid Temperature Extremes: Stick to soft, room-temperature foods and avoid biting down on the painful side of your mouth.
