Feeling under the weather is never pleasant, especially with the added discomfort of aching teeth and gums. But how does sickness affect your dental health?

Your teeth hurt when you’re sick because of referred pain due to underlying causes such as the cold or flu, sinusitis, dry mouth, or cold medication. It’s important, in such cases, to care for your teeth as you normally would.

If you have persistent dental pain, or if you’re worried about your teeth, schedule regular dental exams to help maintain your oral health.

Why Oral Health Matters When You’re Sick

When you’re battling an illness, your teeth may not be the first thing that comes to mind. However, oral health plays a big role in your overall well-being, and neglecting it can exacerbate your symptoms or lead to long-term issues. Understanding the connection between your illness and dental discomfort can help you take better care of yourself, even when not at your peak.

Why Do My Teeth Hurt When I’m Sick?

Many people are surprised to learn that their physical and oral health are closely linked. For instance, your body goes through various changes when you’re sick that can affect your teeth and gums. These changes may cause or worsen dental pain.

The Flu & Colds

When battling the flu or a cold, the virus can lead to inflammation in your sinuses and nasal passages. This inflammation puts pressure on the roots of your upper teeth, causing discomfort and even pain.

Sinus Infections

Sinus infections are notorious for causing dental pain in the upper teeth. The sinuses are located just above your upper teeth, and, when they become inflamed, they can put pressure on the roots of your teeth.  This pressure can mimic the sensation of a toothache, even if there’s nothing wrong with your teeth themselves.

Dry Mouth

Many common illnesses, like the flu or a cold, can cause congestion and breathing through the mouth rather than the nose, leading to a dry mouth. Reduced saliva and dry mouth can lead to your teeth hurting. Without adequate saliva, bacteria can thrive, increasing the risk of cavities and gum disease, which can cause dental pain.

Medication

Medication for a cold or flu, such as a decongestant, can lead to dry mouth because of decreased saliva production. As a result, your teeth may become more sensitive and prone to pain due to increased bacteria and plaque buildup.

Managing Dental Pain When You’re Sick

Knowing what causes dental pain when you’re sick is one thing, but managing it is another. Here are some strategies to help you alleviate dental discomfort when sick.

Keep Hydrated

Staying hydrated is essential for your overall health when sick. Drinking plenty of water helps maintain saliva flow, which keeps your mouth clean and free of bacteria. Avoid sugary or acidic beverages, as they can exacerbate dental issues.

Use a Humidifier

Using a humidifier in your bedroom can help keep the air moist, reducing the likelihood of dry mouth. This can be beneficial for congestion and makes it easier to breathe through the mouth.

Maintain Oral Hygiene

Even when you feel lousy, stick to your oral hygiene routine. Brush your teeth at least twice daily and floss daily to remove food particles and bacteria. Consider using a toothpaste designed for sensitive teeth.

When to Seek Dental Care During Illness

While managing dental pain at home is possible, there are times when you should seek professional dental care. Here are some signs that it’s time to visit your dentist.

Persistent Pain

If your dental pain persists despite your best oral health efforts, it’s time to see your dentist. Persistent pain could indicate an underlying issue that needs professional attention.

Swelling & Redness

Swelling and redness in your gums or face can indicate an infection. If you notice these symptoms, don’t wait to seek dental care. Infections can spread and lead to more serious health issues if left untreated.

Difficulty Eating or Drinking

When dental pain makes eating and drinking difficult, it’s crucial to address the cause promptly. Proper nutrition is vital for your recovery, and prolonged dental pain can interfere with your ability to nourish your body.

The Importance of Regular Dental Exams

If you’re prone to getting sick frequently, regular dental exams can help maintain your oral health. Here’s why you shouldn’t skip those appointments.

Early Detection of Issues

Regular dental exams allow your dentist to detect early potential issues before they become major problems. This can save you from experiencing severe dental pain down the line.

Professional Cleaning

Professional dental cleanings remove plaque and tartar buildup that you might miss with regular brushing and flossing. This helps prevent cavities and gum disease, which can cause dental pain.

Personalized Advice

Your dentist can provide personalized advice on how to care for your teeth. This guidance can help you manage your oral health more effectively and prevent complications.

Prioritize Your Oral Health

Your oral health is an integral part of your overall well-being. Don’t neglect it. Caring for your teeth and gums better equips you to handle whatever illness comes your way.
