What Causes Sensitive Teeth?

You shouldn’t ignore sensitive teeth, they won’t heal over time. If sharp pains are caused by your teeth when brushing them or eating and drinking, you may be suffering from sensitive teeth.

“Sensitive Teeth can affect three in ten people from the UK.”

Sensitive teeth may be a sign of poor oral health. A dentist can help give you advice on how to keep your teeth and gums look healthy.

Sensitive Teeth can be caused by a number of things. These include:

  • Worn tooth enamel. The enamel is the outer layer of each tooth. Over time, it can be worn down by acidy drinks or sugary foods.
  • A Cavity or Chipped Tooth. Damaged teeth can be a cause of sensitive teeth because their structure is compromised.
  • Exposed tooth roots. Overzealous tooth brushing can damage your gums. Gum disease can also leave your tooth roots exposed to everyday activities.

What Solutions are there for Sensitive Teeth?

If your teeth are the cause of pain and are preventing you from everyday activities, we strongly recommend visiting your dentist.

“They’ll be able to pinpoint exactly why your teeth are sensitive and how you can fix them.”

However, here are some common solutions for sensitive teeth:

  • Desensitising toothpaste. A toothpaste brand such as Sensodyne has chemicals specifically designed to help sensitive teeth. They fill exposed tubules in and around the dentin.
  • Clean Your Teeth after every Meal. Lingering bacteria can cause plaque to build up. After having a meal or eating a snack, brush or floss your teeth to ensure bacteria is removed from the surface.
  • Change Your Brushing Technique. You should aim to replace your toothbrush every four months so the bristles are soft along the surface. Brush softer too, and don’t aggressively brush against your gums.
