When you have a cold is not uncommon to have tooth pain or gum pain, and most of the time, it’s nothing to worry about. Here are two of the most common reasons why you may have painful teeth during a cold.
Sinus Pressure
When you have a cold, your sinus cavities just above your upper back teeth can become filled with mucus, making these teeth feel sore. Relieve the pressure by placing a warm damp towel around your nose and cheeks, but if the pain persists, see your doctor just in case you have a sinus infection.
Dry Mouth
When your nose is blocked, breathing through your mouth can result in a dry mouth. Continually breathing through your mouth can dry out your teeth and gums, and lips and a lack of saliva can lead to more plaque buildup over your teeth. This can increase the risk of tooth decay and other dental infections, so regular brushing and flossing are even more important. When you cannot breathe through your nose, make sure you drink plenty of water. Also, many decongestants and painkillers can cause dry mouth, so after taking these medicines, make sure you have a glass of water.
