5 Ways Stress Affects Your Oral Health

You know stress can cause headaches, muscle tension, and trouble sleeping—but did you know it can also affect your teeth and gums? When stress builds up, it doesn’t just weigh on your mind; it can also show up in your smile.

April is Stress Awareness Month, making it the perfect time to recognize the impact stress has on your oral health. If you’ve noticed jaw pain, increased sensitivity, or other changes in your mouth, stress might be the cause. Keep reading to find out more.

Stress is Nothing to Smile About

The physical symptoms of stress can show up anywhere in your body, including your mouth. That’s why managing your stress is so important. The first step in preventing prolonged or high stress from harming your oral health is to recognize the signs. Here are five ways stress can take a toll on your smile—and how to stop it.

1. Teeth Grinding and Clenching

One of the most common ways stress affects your smile is through teeth grinding (bruxism) and jaw clenching. Many people do this without realizing it—especially at night—and it can lead to worn enamel, jaw pain, and even cracked teeth over time.

What to do: If you wake up with headaches or a sore jaw, a custom nightguard can help prevent grinding and protect your teeth.

2. Gum Inflammation and Sensitivity

Stress weakens the immune system, making it easier for bacteria to cause gum irritation, inflammation, and infection. If your gums look red, feel swollen, or bleed when you floss, stress may be playing a role.

What to do: Keep up with daily flossing and schedule regular cleanings to prevent gum disease from progressing.

3. Increased Risk of Cavities

Stress can lead to changes in eating habits—often increasing cravings for sugary foods and drinks. Combined with a lack of saliva (another common stress side effect), this creates the perfect environment for cavities to develop.

What to do: Drink plenty of water, limit sugar intake, and don’t skip brushing and flossing, even on your busiest days.

4. Dry Mouth and Bad Breath

When you’re stressed, your body may produce less saliva, leading to a dry mouth. Since saliva helps wash away bacteria, this can contribute to bad breath and a higher risk of tooth decay.

What to do: Stay hydrated and try chewing sugar-free gum to stimulate saliva flow.

5. Neglecting Oral Care

When life gets overwhelming, self-care—like brushing and flossing—often takes a back seat. Skipping your oral hygiene routine, even once or twice, can lead to plaque buildup, cavities, and other dental issues.

What to do: Try setting reminders or pairing your oral care with another daily habit, like washing your face before bed.
