The Surprising Effects of Stress on Your Oral Health and Teeth
14/05/2025
In today’s fast-paced world, stress has become a common part of daily life for many people across the UK. Whether it’s work deadlines, financial pressures, or juggling family commitments, stress can take a serious toll on your physical and mental wellbeing. But did you know it can also have a significant impact on your oral health?
Here’s how stress can affect your teeth, gums, and overall oral hygiene — and what you can do to protect your smile.
Teeth Grinding and Jaw Clenching (Bruxism)
One of the most common ways stress manifests is through teeth grinding or jaw clenching, often during sleep or without even realising it. This condition, known as bruxism, can lead to:
- Worn-down or chipped teeth
- Jaw pain or tightness
- Headaches
- Damage to dental work such as crowns or fillings
If you’re waking up with jaw soreness or notice your teeth feel sensitive or uneven, it could be a sign of bruxism. Your dentist may recommend a custom mouthguard to protect your teeth at night.
Gum Disease (Periodontal Problems)
Chronic stress can weaken your immune system, making it harder for your body to fight off the bacteria that cause gum infections. You may notice:
- Swollen, bleeding gums
- Bad breath
- Gum recession
If left untreated, this can progress to periodontal disease, which may lead to tooth loss and impact overall health. Regular dental check-ups and good oral hygiene are key to prevention.
Dry Mouth (Xerostomia)
When you’re stressed, your body may produce less saliva, leading to dry mouth. Saliva plays a crucial role in protecting your teeth by neutralising acids and washing away food particles.
A persistently dry mouth can increase your risk of:
- Tooth decay
- Gum disease
- Mouth ulcers
Staying hydrated and using sugar-free chewing gum or saliva substitutes can help manage dry mouth symptoms.
Canker Sores and Cold Sores
Stress has been linked to the appearance of mouth ulcers (canker sores) and cold sores. While canker sores are not contagious, they can be painful and affect eating and speaking. Cold sores, caused by the herpes simplex virus, can be triggered by emotional stress and usually appear on or around the lips.
Keeping stress in check and maintaining good general and oral hygiene can reduce the frequency of flare-ups.
Neglecting Oral Hygiene
When you’re overwhelmed or emotionally exhausted, brushing and flossing might fall down your list of priorities. But skipping basic oral care can quickly lead to plaque build-up, cavities, and gum inflammation.
Even during stressful times, try to stick to your routine:
- Brush twice daily with fluoride toothpaste
- Floss or use interdental brushes once a day
- Limit sugary snacks and drinks
Tips to Protect Your Oral Health During Stressful Times
- Practice stress management: Regular exercise, meditation, breathing techniques, and talking to a friend or therapist can help manage stress levels.
- Stay hydrated: Water is vital for your overall health and helps keep your mouth moist and clean.
- Visit your dentist regularly: Regular check-ups can help detect early signs of stress-related dental issues.
- Be mindful of clenching: If you catch yourself clenching your jaw, try relaxing your face and doing a few jaw stretches.
Stress doesn’t just affect your mind — it impacts your entire body, including your mouth. By being aware of the signs and taking simple steps to manage stress, you can protect your teeth and gums and maintain a healthier, happier smile.
