How Stress Affects Your Oral Health: Tips for Managing Stress-Related Dental Issues

Stress. It’s normal for humans to experience it and, in small amounts, it’s actually healthy and staves off boredom and depression.

But when talking about stress, the conversation is usually regarding too much of it – which is unhealthy, contributing poor health and anxiety.

There is lots of research covering the negative effects of stress on the entire body, including your oral health. In this post, Victorian Dental Group outlines how stress affects your oral health, offering tips for managing stress-related dental issues:

Stress weakens the immune system

One of the key ways in which stress can impact your dental health lies in a weakened immune system. When you’re under too much stress, your immune system is compromised which leads to a decreased effectiveness in fighting off bad bacteria in the mouth. This bacteria is what causes oral health problems like cavities and gum disease.

The ideal solution here is to reduce your stress levels, which may require lifestyle changes, taking up activities like meditation, or seeking professional help from a psychologist. Professional therapists can help you reduce and manage stress with techniques and advice.

Stress sometimes causes teeth grinding

Teeth grinding is often associated with high levels of stress, leading to damaged enamel and dentin – the two outer layers of your teeth. If you’re waking up with a sore jaw and/or headaches, this could be a sign that you’re grinding your teeth in your sleep.

A dentist can examine your mouth for signs of teeth grinding and can offer a custom-made mouthguard for sleeping, also known as a nightguard. This protects your enamel and dentin from being worn down due to grinding.

Stress can cause dry mouth

Dry mouth is another oral health symptom of stress, leading to increased levels of harmful bacteria in your mouth. Saliva is your mouth’s natural defence against harmful bacteria, meaning a dry mouth creates a hospitable environment for bad bacteria. This increases your risk of tooth decay and gum disease.

Whether you’re experiencing stress or not, it’s important to keep hydrated, brush twice a day, and floss at least once a day. If you’ve got a consistently dry mouth, try chewing a sugar-free gum to stimulate your salivary glands.

Stress can bring on bad coping habits

Stress often causes us to take on bad coping mechanisms such as eating junk foods, excessive alcohol consumption, and smoking. These habits are all detrimental to our oral hygiene. If you’re struggling with any of these addictions, help is available and it might be worth seeing a professional therapist.

While stress can affect your oral health, our team of skilled, empathetic dentists and hygienists at Victorian Dental Group can help get your oral hygiene back on track. Our team understands the effects of stress on your oral health, and implements plans to improve your oral hygiene, preventing cavities and gum disease.
