Sudden Tooth Pain or Sensitivity? Here’s What You Should Know

Causes of Sudden Tooth Pain — and When to Seek Urgent Dental Care

No one wants to experience tooth pain that seems to come out of nowhere – perhaps while sipping on a morning coffee or tucking into dinner. Whether it’s caused by tooth decay, injury, or infection, understanding the triggers is crucial. More importantly, knowing when to contact a local emergency dentist can prevent complications and relieve pain fast.

Tooth pain has a range of potential causes, such as:

  • Tooth decay 

Dental cavities are the most common cause of tooth pain. They tend to be caused by inadequate oral hygiene, such as a failure to brush or floss regularly. 

  • Dental abscesses 

In the event of dental trauma or a cavity reaching the tooth’s “pulp chamber”, an abscess can occur. This is an accumulation of pus in the teeth or gums, caused by an infection. In such cases, it’s important to book an emergency dental appointment promptly to prevent the spread of infection and alleviate severe discomfort.

  • Cracked or fractured teeth 

A dental injury – bringing about the cracking or fracturing of one or multiple teeth – is one of the most apparent sources of tooth pain. 

  • Gum disease 

If plaque builds up due to poor dental hygiene, this can cause gum disease – such as gingivitis, or the more severe periodontitis – over time. Untreated gum disease can lead to tooth loss. 

  • Tooth Sensitivity 

Hot, cold, sweet, or acidic stimuli can cause the sharp pain that most of us recognise as tooth sensitivity. This may occur due to such factors as enamel erosion and/or dental damage. 

  • Impacted wisdom teeth 

If you experience pain in the upper back and bottom molar area of your mouth, and your wisdom teeth are still intact, this could indicate the right time to remove them. 

When To Seek Professional Emergency Dental Care ?

If you experience any of the following alongside your tooth pain, we urge you to seek an immediate dental consultation

  • Swelling 
  • Fever 
  • Difficulty opening your mouth 

You should also seek an urgent appointment with your local dentist if your tooth pain has lasted for more than two days or if you experience sudden, sharp pains that don’t subside. 

Having your teeth seen quickly by a professional will enable you to receive an accurate diagnosis and the most suitable treatment. 

Home Remedies for Temporary Release

While you wait for emergency dental care, there are a few things you can try at home to help relieve tooth pain. These include: 

  • Applying ice or a cold compress to the outside of the face 
  • Taking over-the-counter pain medication
  • Using a pain-relieving gel for the mouth, as can be purchased from supermarkets or pharmacies 
  • Rinsing the mouth with salt water 

If you need to eat between now and your appointment, try to consume only soft foods, such as yoghurt and scrambled eggs, while avoiding chewing on the sore tooth as much as possible. 

Preventative Measures 

The best way to prevent sudden tooth pain is to practise the highest standards of oral hygiene. 

This means you should be: 

  • Brushing your teeth twice a day 
  • Flossing regularly 
  • Arranging regular dental checkups
  • Minimising your intake of sugary foods and drinks 

You can further reduce the risk of sudden tooth pain — and avoid unexpected emergency dentist visits — by wearing a mouthguard when playing sports or taking part in activities that could cause trauma to the teeth or jaw.

If you’re experiencing tooth pain or sudden swelling – or any other signs of a dental emergency, such as a knocked-out or broken tooth due to trauma – it’s crucial not to wait.
