Have you ever had a cold and, along with the usual symptoms like a stuffy nose, cough, and sore throat, noticed your teeth feeling sore and sensitive too? If so, you’re definitely not on your own.

A lot of people ask themselves, “Why do my teeth ache when I catch a cold?” In this article, we’re going to explore what causes this curious situation, share some expert knowledge, and give tips on easing the pain. We’ll also tackle a few common questions that might be on your mind.

When you catch a cold, your body goes into battle mode against the virus. This battle can have some surprising side effects, including dental pain. Here are a few reasons why this happens:

Sinus pressure

The most frequent explanation for tooth pain during a cold ties back to sinus pressure. Specifically, your maxillary sinuses, which are situated just above the upper molars, are prone to inflammation and can fill up with mucus during a cold. This buildup of pressure doesn’t just stay in the sinuses; it can exert a downward force on the roots of your upper teeth, leading to a dull, persistent ache. It’s a deceptive kind of pain – you might swear it’s your teeth that are the issue, but the real troublemaker is the pressure from your sinuses.

Changes in blood flow

In its effort to fend off the cold virus, your body naturally increases blood flow to certain areas, aiming to bolster its defence mechanisms. This heightened circulation, however, has a side effect: it can amplify sensitivity and discomfort in various parts of your body, your teeth included. If you already have dental issues, such as cavities or gum disease, this increased blood flow can exacerbate the sensation of pain, making pre-existing conditions feel even more aggravating during a cold.

Dehydration

Colds are notorious for dehydrating the body, a situation that’s only worsened if you’re running a fever or finding yourself sweating more than usual. Saliva plays a crucial role in maintaining oral health, acting as a natural barrier against decay and disease. When your body is dehydrated, saliva production dips, leaving your teeth more exposed and susceptible to both pain and sensitivity. This decreased saliva can fast-track the discomfort you’re feeling in your teeth, making hydration a key factor in managing cold-related dental pain.

Understanding these connections between a common cold and dental discomfort not only helps in addressing the symptoms more effectively but also highlights the importance of holistic health. Taking care of your body during a cold involves more than just managing the immediate symptoms; it’s also about paying attention to the less obvious effects, such as dental pain, and taking steps to mitigate them. Whether it’s staying hydrated, using saline sprays to relieve sinus pressure, or simply being aware of the body’s interconnected responses, recognising and addressing these factors can significantly ease your overall discomfort during a cold.

When you’re having a toothache during a cold, it’s not just uncomfortable; it can add to the overall misery of being sick. While it’s crucial to see a dentist if your toothache doesn’t go away or if you’re unsure why it’s happening, there are several strategies you can try at home to make that pain more bearable during a cold:

Stay hydrated

Keeping well-hydrated is essential, especially when you’re sick. Drinking plenty of water does more than just keep your throat moist and help manage a fever; it also helps thin out the mucus that might be contributing to sinus pressure and, by extension, tooth pain. Moreover, staying hydrated ensures that your saliva production remains at optimal levels, providing a natural defence against tooth decay and discomfort.

Use a humidifier

Dry indoor air, especially during colder months, can worsen sinus pressure and tooth pain. Using a humidifier adds moisture to the air, which can help relieve the pressure in your sinuses and the discomfort in your teeth. If you don’t have a humidifier, spending some time in a steamy bathroom can offer temporary relief.

Keep brushing your teeth and flossing

It might be tempting to skip your oral hygiene routine when you’re not feeling well, for a day or two… but maintaining it is more important than ever. Brushing twice a day and flossing can help prevent additional oral health issues that could exacerbate your tooth pain. If your teeth are particularly sensitive, consider using a toothpaste designed for sensitive teeth to provide some relief.

Consider pain relievers

As a last resort, if you tried everything and nothing seems to work, you can try pain relievers. These painkillers can be quite effective at easing toothaches and other pains caused by a cold. Just make sure to follow the instructions on the label carefully and most importantly, consult with your doctor before taking them, especially if you’re taking other medications already.

See your dentist

If your toothache is severe, doesn’t improve, or you just can’t figure out why it’s happening, making an appointment with your dentist is the best course of action. They can help identify the cause of your pain, whether it’s directly related to your cold or something else, and suggest appropriate treatments to provide relief.

Remember, dealing with a toothache on top of a cold can make you feel worse, but taking steps to manage the pain can help you feel a bit better as you recover. Keeping up with your hydration, air moisture, oral hygiene, and considering safe pain relief methods are all practical ways to ease the discomfort until you’re feeling well again.

The connection between colds and tooth pain is a reminder of how interconnected our body systems are. Understanding “why do my teeth hurt when I have a cold” helps us better address the discomfort and take steps to alleviate it.

Remember, if you’re ever in doubt about the cause of your tooth pain, consulting with a dental professional is always the best course of action. Stay informed, stay healthy, and keep smiling, even through the cold season!
