Understanding Dental pain

  • Many people experience painful teeth and gums. This is also known as dental pain.
  • Dental pain is often a continuous throbbing pain, but it may come and go.
  • Sometimes, the pain’s worse at night, or during eating and drinking, especially if the food and drinks are hot or cold.

Dental pain is not always felt in the teeth. Sometimes the pain can spread to the face and jaw.

Tooth decay is one of the most common causes of dental pain.

However, dental pain can also be caused by:

  • A cracked tooth
  • Loose or broken fillings
  • Receding gums – this exposes more sensitive parts of the tooth not covered by enamel
  • An infection in the tooth or jaw
  • Wisdom teeth breaking through the gums
  • Braces
  • Clenching or grinding your teeth
  • Sinus congestion – may feel like toothache just as toothache sometimes feels like sinus pain

Prevent dental pain by taking good care of your teeth

  • Brush regularly – twice a day using a soft brush; don’t forget to brush gums and tongue as well
  • Use a fluoride-containing toothpaste – if you have sensitive teeth, choose a toothpaste designed to reduce sensitivity
  • Clean between teeth with dental floss or interdental brushes to remove plaque
  • Use mouthwash
  • Try to avoid sugary foods and drinks
  • Don’t smoke
  • Chew sugar-free gum to stimulate saliva production

Understanding Tooth Decay

Why do I get dental pain from tooth decay?

Teeth are made up of layers – the hard enamel on the outside, a softer layer below, and then a soft centre called the pulp, where the nerves and blood vessels are. Decay can wear through the outer layers of the tooth. When it reaches the pulp, the nerves are exposed, causing pain. The pulp may also get inflamed or infected and you may require root canal relief. That’s why it’s important to see your dentist if you have toothache for more than one to two days. The longer you leave it, the greater the chances of the tooth getting infected.

Over-the-counter pain relievers such as ibuprofen or paracetamol may help ease the pain until you see your dentist.
