Why do I get sensitive teeth?

A normal healthy tooth is hard as nails, well not literally, but the hard protective cover (enamel) is the hardest substance in the body and provides good protection against sensitivity. Its job is to shield the soft inner of the tooth that contains the nerves and blood supply.

If your tooth enamel thins, areas beneath the enamel become exposed. Once that happens, they become more sensitive and you can start to suffer from hot and cold sensitivity.

Why are my teeth so sensitive?

If you suffer from sensitive teeth, you’re not alone. Tooth sensitivity is very common, in fact it’s estimated that half the population suffer from sensitive teeth. Most people notice their tooth sensitivity when they eat or drink something hot or cold, but if you’re a sufferer, even a blast of cold air can get you wincing. Don’t panic, sensitivity doesn’t necessarily mean complicated or uncomfortable dental treatment – it may however, be a sign that you need to improve your oral health.

What are the main causes of sensitive teeth?

There are a few causes of sensitive teeth;

  • Acid erosion caused by common food and drinks wearing away the enamel
  • Sugary foods – these encourage the growth of bacteria, which can cause gum recession leaving sensitive areas exposed
  • Brushing too hard. Yes, there is such a thing as brushing too hard, since over brushing can wear away tooth enamel

Simple tips to protect your teeth against sensitivity:

  • Brush gently twice a day; your dentist may recommend a sensitive toothpaste
  • Clean between your teeth at least once a day using floss or an inter-dental brush
  • Rinse with LISTERINE® Total Care Sensitive for 30 seconds twice a day after brushing
