Sensitive teeth are most often caused by an irritation of the nerve inside your tooth. Cold, hot or even sweets can irritate the nerve through tiny microscopic holes in our enamel called microtubules. Here are some tips to help!
- First, avoid really cold or hot drinks… Duh! And of course limiting sweets also helps avoid tooth decay!
- Use a soft bristle tooth brush and brush in a circular motion. Hard brushing with hard bristles in an up and down or back and forth motion can start to wear away at your enamel and gums, taking away our tooth’s natural protective layer.
- Proper Oral hygiene like brushing twice a day and cleaning between your teeth keep your teeth plaque free. Think of plaque as the acid producing bacteria's home. The longer plaque stays on your tooth the more erosion and potential for sensitivity.
- Use a Sensitivity tooth paste like Sensodyne. These tooth pastes contain potassium nitrate or strontium chloride that help close off microtubules. Rubbing these toothpastes on our teeth before bed or avoiding rinsing after brushing can help increase their effectiveness.
- Be careful! Tooth sensitivity can also result from more serious dental diseases like enamel erosion, abfraction, dental decay or broken teeth. Most of these can be treated by your dentist but the longer you wait the more in depth the procedure may be.
