Sensitivity to hot/cold
Are your teeth sensitive to cold or hot food/drinks? This can be caused by gum recession where the gumline recedes back on the tooth exposing tiny channels that send those temperature signals to the nerve of the tooth. Sensitivity toothpaste can help alleviate these feelings by blocking those tiny channels. Any toothpastes with Stannous Fluoride or Potassium Nitrate as the active ingredient will accomplish this. These toothpastes take about 2 weeks to feel the full effect of blocking the sensitivity. If your sensitivity doesn’t improve within 2 weeks, there could be another cause and you may want to bring it up to your dentist at that time.
