Tooth Sensitivity FAQs:

  • Dentin hypersensitivity or tooth sensitivity is a common dental problem that can arise when dentin (the inner part of the tooth) becomes exposed. It’s a condition that can develop over time as a result of common problems such as receding gums and enamel wear.

  • Tooth sensitivity can start when the softer, inner part of the tooth called dentin becomes exposed. Dentin lies under the enamel and the gums. Thousands of microscopic channels run through the dentin towards the centre of the tooth. Once the dentin is exposed, external triggers (like a cold drink) can stimulate the nerves inside the tooth, resulting in the typical short, sharp pain of tooth sensitivity.

  • Talk to your dentist about your symptoms. They can confirm that tooth sensitivity is the cause of your problem and advise you on how to care for sensitive teeth, like the best toothbrushing technique for you, how often and when. You can also  relieve the painful symptoms of tooth sensitivity by changing your regular toothpaste to a daily use toothpaste specially formulated to treat sensitive teeth, like Sensodyne®.

  • Tooth whitening here means whitening treatments carried out under the supervision of your dentist. These treatments contain bleaching agents (peroxide), which are known to cause sensitivity in some patients. This is not the same as dentin hypersensitivity, which happens as a result of having exposed dentin (the softer, inner part of the tooth). Ask your dentist about bleaching-related sensitivity if you are considering having a tooth whitening treatment.

Acid Erosion FAQs:

  • The wearing away of enamel, caused by acid in our diet, is called Acid Wear.  As few as four acidic foods or drinks throughout the day can put our enamel at risk from acid wear. If your tooth enamel is at risk, ask your dentist for advice on what foods to eat, how to consume the many acidic foods and drinks in today's diet and the best oral hygiene routine for you.

  • Over time, acidic foods and drinks can cause your teeth enamel to wear down. These include fruit and fruit juices, carbonated drinks, black coffee or tea, wine and anything that tastes sharp, like ketchup or salad dressing. To help protect your teeth against acid erosion, talk to your dentist and use a fluoride toothpaste specially developed for people at risk of acid wear, such as Pronamel. Ask your dentist for dietary advice on the best oral hygiene routine for you and the best way to consume the many acidic foods and drinks in today's diet.

  • Yes. Acid erosion can contribute to enamel wear. Enamel is the hard outer layer of a tooth. Although it’s harder than any other substance in the body, with time it can gradually be worn away to expose the layer of dentin beneath, which may lead to tooth sensitivity.
