Teeth can not only be sensitive to food temperature, but they can also be affected by weather conditions. Have you ever opened your mouth to speak or yawn on a cold winter day and felt a shooting pain on one of your teeth?
It is not uncommon for people to be sensitive to the temperature outside, but cold weather seems to be more of a problem than warm temperatures.
Why Are Teeth Sensitive to Cold Weather?
Even though teeth are hard and made of bone, they are living parts of your body and have nerve centers on the tip of the root. If those nerves are exposed to cold food and air temperature you could get a shock that makes you cringe.
The enamel in your teeth, protects the inner layers from decay and also protect the nerves from being exposed. But when there is damage to the enamel, the teeth can crack or develop cavities, which are small holes that with time, grow and reveal more and more of the inner part of the tooth, leaving it vulnerable.
When the enamel no longer protects the nerves at the end of the root, your teeth become sensitive to temperature. Tooth sensitivity can also be caused by temporomandibular joint disorders (TMD) such as bruxism.
Bruxism is the unconscious clenching and grinding of the teeth due to anxiety, tension, and other factors. This repeated motion of touching the teeth against each other with force can wear the enamel off and cause sensitivity. Another reason for tooth sensitivity is receding gums, where the gums become weaker and start to come apart from the tooth. This condition also exposes the inner layers of the teeth and makes them sensitive.
