What's Up

Is the weather really making my teeth hurt?

My tooth hurts every time it rains.  

Atoms and molecules in the air are in constant motion and the total pressure exerted from them creates what we call air pressure.

Changes in air pressure alter the body's oxygen levels. The body attempts to regulate those levels by releasing oxygen stored in your sinus cavities to alleviate pressure on the hollow bones of the face. The problem arises from nasal passages being blocked due to sudden shifts in barometric pressure and the trapped oxygen having nowhere to escape from. This causes the pain above the eyes, nose and jaw that is referred to as a "pressure headache."

Sudden drops in barometric pressure will result in the swelling of the lining of your nasal passages.  This results in what’s best known as a "sinus headache."  Since the purpose of the sinus cavities is to keep the head "light," the feeling of having them clogged is often described as having a heavy head. This leads to increased fatigue and may lead to migraine headaches.

Tooth pain is a common effect of a persistent sinus infection. Sometimes teeth actually extend up into the sinus cavity making them more susceptible to this type of tooth pain.  It may feel like a toothache from a cavity, but will typically come on suddenly and may remain as a dull throbbing pain in the upper teeth. 

Orthodontic movement of the teeth can instigate this tooth pain as well during the stormy weather.  

However, even with this simple explanation of a very common dilemma, don’t’ ever take tooth pain lightly.  See your dentist for a definitive diagnosis of the source of pain.
