Let’s talk sensitivity!


You may be wondering what causes tooth sensitivity and how to treat it? There are many different causes that can trigger your teeth to feel sensitive.                                                                                                                                                                                                                                                                                                                                                                                                  

Food and drinks 

If you are regularly eating lots of acidic foods and snacking frequently, this can cause the enamel on your teeth to erode which can be the cause of your sensitivity. Foods and drinks such as soft drinks, lemon water, energy drinks, juice and some fruits such as mandarins and oranges are all very high in acidity. You don't need to cut out all of these completely as we all crave these foods sometimes, however here are a few ways to help prevent acid erosion and sensitivity.

  • Rinsing- rinse your mouth with water straight after having something acidic. Rinsing will help neutralise the acid in your mouth and reducing acid wear on your teeth.
  • Swap to less acidic foods such as milk, water, cheese and bananas. 
  • Eat/drink in moderation. Try to only have these foods every now and then to reduce the acidic wear on your teeth.
  • Use a sensitive toothpaste and brush gently using a soft toothbrush.
  • After eating/drinking acidic foods, wait for 30 minutes before you brush. Acid softens the enamel, so if you brush immediately you may be 'brushing away your enamel'.

Periodontal disease

Periodontal disease, also known as gum disease, is a gum infection that can not only affect your gums, but the bone supporting your teeth as well. If periodontal disease is left untreated, your bone and gums recede causing your tooth root to become exposed. The tooth root doesn't have enamel to protect the underlying layers, so sensitivity can occur. There are many causes for gum disease with factors including smoking, diabetes, poor oral hygiene and some medical conditions.

If think you have gum disease or are experiencing symptoms, come in and see one our friendly dentists for a checkup, diagnosis and treatment options.


Have you ever been overwhelmed with all the different types of toothbrushes at the store? We recommend a soft bristled toothbrush as it is possible to wear away your enamel and recede your gums just from brushing too hard! If you were to brush your teeth in a “scrubbing” motion with a hard bristled toothbrush you can "brush away your gums", exposing your root surface which is highly sensitive as it is not protected by enamel. We recommend brushing in gentle circles around your teeth and gums which will also help to reduce any plaque build-up.


Although whitening your teeth makes you feel great and gives you a whiter smile, it is important to make sure you follow the correct aftercare procedures. If you don't or are more susceptible, you may feel more sensitivity. Make sure you consult with a dentist before trying any at-home whitening yourself, as unfortunately if you already have sensitive teeth, you may not be a good candidate for whitening.


You may not even realise it, but your tooth sensitivity could be due to bruxism, also known as grinding or clenching your teeth. You may find yourself doing it during the day, or you may find you are waking up with sore teeth or headaches. This means you may be subconsciously grinding or clenching in your sleep. Some of the common reason for bruxism are anxiety, stress, tension, aggressive or competitive personality, caffeine and some medications. As there are so many possibilities as to why you could be grinding or clenching it is best to visit your dentist so they can help treat the issue.  If you cannot stop your clenching habit, you can get a splint made here at Dental Aspects, which may help to prevent further damage to your teeth.

Broken, chipped, decayed teeth

One of the more unfortunate reasons for tooth sensitivity could be a broken, chipped or decayed tooth. If you are experiencing sensitivity to hot or cold, or are feeling sharp shooting pains, it is best to come in a see a dentist straight away. Regular dental visits are also receommended to help keep your teeth in their best condition.
