Sore Teeth When You're Ill: The Causes Explained -

Body aches, a runny nose and scratchy throat are par for the course when you have flu. But another less-than-stellar symptom is sore teeth.

Not to be confused with the sharp, nerve-jangling pain of a cavity, illness-related sore teeth are characterised by a dull, throbbing ache. “Illnesses like the common cold, flu or sinus infections can cause your sinuses to become inflamed and filled with mucus,” says dentist Dr Rhona Eskander. “Since the roots of your upper teeth are close to your sinus cavities, this pressure can cause tooth pain.”

Your body’s immune response, as it fights off the virus or bacteria causing your illness, is also a factor. “Our immune response often involves increased blood flow to the affected areas, including the mouth and gums,” she adds. “This can result in heightened sensitivity, while the production of extra white blood cells and other immune system activities can sometimes contribute to discomfort or aches in different parts of the body, including the teeth.”

One small mercy is that your sore teeth are only temporary and, while it may be unpleasant, it's actually a sign that your immune system is hard at work, ramping up its efforts to get you well again. Until that time, here are some ways to help soothe the pain.

How to soothe tooth pain when you're ill

1.Warm salt water rinse

You probably know that gargling with warm salt water can help with a sore throat. But warm salt water can also help to ease sore teeth as it's an anti-inflammatory and temporarily increases the pH balance of your mouth, creating an alkaline environment in which bacteria struggle to survive. “Dissolve a teaspoon of salt in a cup of warm water and gently swish it around in your mouth,” says Dr Eskander. “This can help reduce swelling and soothe sore gums.”

2. Probiotic mouthwash

This is not the time to go in hard with any alcohol-based oral care products, but if you are wedded to mouthwash, Dr Eskander recommends switching to one laced with probiotics. “Probiotics in the mouthwash can contribute to a healthier oral microbiome,” she says. “This is particularly helpful when your body’s immune system is busy fighting an illness, as it can provide additional support in maintaining oral health. Probiotics can also have a soothing effect on inflamed or irritated gums, which might be a side effect of being ill and the body’s immune response.” Try PÄRLA Probiotic Mouthwash, which comes in eco-friendly tablets .

3. Maintain good oral hygiene

It's easy for your normal beauty routine to become derailed when you're ill and oral hygiene often slips down the list of priorities. But Dr Eskander says that should try to continue brushing gently in a circular motion twice daily and flossing. “Good oral hygiene can prevent additional dental issues and may reduce discomfort,” she notes.

Not drinking enough fluids can dry out your mouth and trigger sore teeth; breathing through your mouth when you have a blocked nose can have a similar effect. “Drinking plenty of fluids can help to keep your mouth moist and reduce discomfort from tooth pain,” says Dr Eskander, adding that you should avoid very hot or cold drinks if your teeth are suddenly sensitised.

5. Use a humidifier

“If sinus pressure is the cause of your tooth pain, using a humidifier in your bedroom can help to reduce sinus pressure and congestion,” says Dr Eskander. The Dyson Purifier Humidity + Cool Formaldehyde PH04 is considered the gold standard as you can choose to cool, humidify and even purify the air in your home by destroying formaldehyde, a potentially harmful chemical found in smoke from log fires, among other things. A less pricey option is the Humio Humidifier.

6. Pain relief

“Over-the-counter pain relievers like acetaminophen or ibuprofen can help ease the discomfort,” Dr Eskander says. “However, it’s important to use these as directed and consult with a healthcare provider if you have any concerns. Remember, if your tooth pain persists or is severe, it’s important to consult with a dentist to rule out any specific dental issues.”
