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 dentine beneath, which may lead to tooth sensitivity.

Enamel wear can be caused by:

What is Enamel Wear?

Tooth Grinding

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

Tooth Brushing

If you brush too frequently 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, and try using a soft-bristled toothbrush like the Sensodyne Multicare Toothbrush.

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 such as ketchup or salad dressing. As few as four acidic 'challenges' throughout the day can put your enamel at risk from acid erosion, also known as acid wear. If you feel your tooth enamel could be at risk of acid wear, talk to your dentist:

  • Ask for advice on the best tooth brushing technique and oral hygiene routine for you
  • Ask for dietary advice, and how best to help protect your teeth against the effects of acid wear, brushing twice a day with a fluoride toothpaste such as Repair & Protect.

Tip: Your dentist can spot the early signs of tooth wear so it's important to go for regular dental check ups. If you think you might be at rist of enamel wear, talk to your dentist.
