Having sensitive teeth is a common dental concern that anyone can experience. The symptoms can be triggered when teeth get exposed to cold air, cold or hot beverages, or sweets. Sometimes, the cause of sensitivity is unknown. The team at Sehnert Precision Dentistry wants to help you understand the causes of sensitive teeth.

Tooth enamel is the outer, protective layer of the tooth. It covers the second layer, called dentin. The dentin contains thousands of tiny channels leading to the pulp, which contains the nerve endings of the tooth. When the dentin is exposed, sensitivity can result.

What Causes Sensitive Teeth?

Teeth Grinding or Clenching. This habit can cause sensitivity by gradually wearing down the enamel of the teeth.

Gum Recession. It usually occurs with advanced forms of periodontal disease when the receding gums expose the dentin.

Acidic Foods. The acidity of some foods can wear down enamel and expose the dentin, causing sensitivity.

Cracked Teeth. Damaged teeth can be a breeding ground for bacteria and cause pulp inflammation. Sometimes, abscesses may develop.

Hard Brushing. When you brush with a toothbrush that is too hard, the tooth’s enamel can wear down, causing exposure of the dentin and possibly gum recession.

Dental Procedures. After receiving dental treatment, the teeth may be temporarily sensitive after the appointment.

Mouthwash. Mouthwash containing alcohol can make sensitivity worse if the dentin is exposed.

You can help prevent sensitivity by always using a soft-bristled brush and maintaining good oral hygiene. Use a toothpaste made for sensitive teeth. If you grind your teeth, we can explain your options to protect your teeth from worn enamel and fractures.

When tooth sensitivity occurs, it is usually a quick, sharp pain that lasts for a short time. But if it becomes a recurring problem, get evaluated to identify the source. Contact our office to schedule an appointment. We serve patients in Lewisville, Texas, and the surrounding areas.
