Causes of Sensitivity

What is Enamel Wear?

Enamel is the hard outermost surface of a tooth. Although it’s harder than any other substance in the body, over time it can gradually wear away to expose the dentin beneath, which may lead to tooth sensitivity.

Enamel wear can be caused by:

Teeth Grinding

Do you grind your teeth at night or during the day? If so, you may be wearing down the enamel, which over time can expose the underlying dentin.

Teeth Brushing

If you brush too often or too hard, eventually your tooth enamel may be worn away or you could develop receding gums.

To prevent this ask your dentist or hygienist for advice on the best tooth brushing technique and oral hygiene routine for you. Try using a soft-bristled toothbrush like the Sensodyne® Precision Toothbrush as well.

Acid Erosion

Over time, acidic foods and drinks can cause your tooth enamel to wear down. This is called acid erosion. Acidic foods and drinks include fruit and fruit juices, carbonated drinks, black coffee or tea, wine, and anything that tastes sharp like ketchup or salad dressing. Having these even just four times a day can put your enamel at risk from acid erosion, also known as acid wear. If you think you're at risk, ask your dentist for advice on:

  • The best tooth brushing technique and oral hygiene routine for you.
  • What to eat and drink, and how brushing twice a day with a fluoride toothpaste like Pronamel can help protect your teeth.

TIP: Your dentist can spot the early signs of tooth wear so it's important to go for regular dental check ups. Talk to your dentist if you think you might be at risk.
