This very common problem can be experienced when you eat or drink something cold, hot, acidic or sweet. There are some possible reasons for this sensitivity.
- Brushing too hard- Scrubbing your teeth or using a side-to-side technique can lead to gum recession and wearing of the enamel on your teeth. This can lead to increased tooth sensitivity. Vigorous brushing, abrasive toothpastes (such as whitening toothpastes or toothpastes containing baking soda).
- Gum Disease- Gum disease may cause the gums to recede which can expose the roots of the teeth. The exposed roots are covered by a very thin soft covering and once that covering is lost the dentin of the root is exposed. The dentin has lots of microscopic channels that run from the root surface, through the dentin to the center of the tooth where the nerve is. These channels contain fluid and when cold or hot fluids are eaten or drank this irritates the nerve when leads to sensitivity and pain.
- Diet – an acidic diet (pickles, soft drinks, citrus fruits) can cause erosion and expose the dentin. This leads to tooth sensitivity.
- Grinding & Clenching- can cause most or all of the teeth to feel sensitive.
- Fractured, chipped or broken teeth- can expose the dentin and cause tooth sensitivity.
