We have all experienced sensitive teeth. But some people may be dealing with this issue worse than others. The discomfort persists and intensifies over time. What could be the reason?

Here’s a list of possible causes of tooth sensitivity, which you and your dentist can discuss further during your dental visit:

• Aggressive Brushing. Overzealous brushing can lead to increased tooth sensitivity. The enamel can wear and cause teeth to lose their protective barrier. Using a hard-bristled toothbrush can also contribute to dental erosion. As the enamel erodes, the more sensitive layer below, called “dentin,” becomes exposed. This makes it easier for hot and cold temperatures to reach the nerves and trigger discomfort.
  
  
• Gum Recession. Receding gums can make a person more vulnerable to sensitive teeth. As the gums pull back from the teeth, the dentin becomes more prominent. Dentin is home to tiny tubes connected to the nerves. Exposure to hot, cold, or anything sweet can stimulate the nerves and lead to bouts of pain or discomfort. Gum recession is one of the symptoms of gum disease. Harmful bacteria accumulating on teeth and gums can lead to infection. The gums become tender, more sensitive, and begin to recede.
  
  
• Cracked Teeth. A broken, fractured, or cracked tooth may feel sore and sensitive. You may experience discomfort when chewing your food or when your teeth are exposed to extreme temperatures. The pain can be on and off and recur at any time. Cracked parts of the tooth may move when you eat and chew and irritate the pulp. Left unfixed, these movements can eventually damage and infect the pulp and heighten tooth sensitivity.
  
  
• Tooth Grinding and Clenching. Clenching and grinding your teeth can also lead to enamel erosion and sensitivity. These conditions may be tough to diagnose, as they can occur only during sleep. The causes can vary depending on when they happen. Daytime clenching is linked to stress and anxiety, while nighttime clenching is connected to sleep apnea and acid reflux, among many others.
  
  
• Acidic Diet. Regular and excessive consumption of foods and beverages high in acids can also make teeth more sensitive. Too much acid can weaken the enamel and make it hard to replenish lost minerals. Limit your intake of anything acidic or, if applicable, use a straw to minimize direct contact with the teeth. Drinking plenty of water to neutralize acid levels in the mouth and flush down acidic substances that could erode the enamel is also helpful.

There are more potential reasons why teeth become sensitive, such as worn dental work and undergoing dental procedures. Old and damaged fillings can cause the dentin and nerves to become exposed, while some procedures, such as teeth whitening, can leave teeth sensitive as a temporary side effect.
