Affinity Health, a leading provider of high-quality health cover, is highlighting the often-overlooked connection between stress and oral health during National Oral Health Month.
Stress is commonly linked to headaches, muscle tension, poor sleep, and exhaustion, but it can also affect oral health. Over time, ongoing stress may contribute to jaw pain, worn teeth, dry mouth, and worsening gum problems.
Stress does not directly cause tooth decay or gum disease, but it can lead to physical changes and habits that leave the mouth more vulnerable. Work demands, financial worries, relationship problems, or prolonged anxiety may eventually leave noticeable signs on the teeth and gums.
Teeth Grinding Can Cause Lasting Damage
One of the clearest links between stress and dental damage is bruxism, the grinding or clenching of the teeth. It can happen during the day or while sleeping, often without the person realising it.
Over time, the pressure can wear down enamel, chip or crack teeth, damage fillings, and cause sensitivity. It may also strain the jaw joints and muscles.
Warning signs include morning headaches, jaw pain, discomfort around the ears, difficulty opening the mouth fully, and visibly worn teeth. A sleeping partner may also hear grinding at night.
A dentist can check for signs of wear and may recommend a custom-made mouthguard or splint. While this may not stop the grinding, it can protect the teeth from further damage.
Stress May Worsen Gum Problems
Plaque, a sticky film of bacteria, is the main cause of gum disease. Stress does not directly cause gum disease either, but ongoing stress can weaken the body’s ability to control inflammation and fight infection.
Stress can also lead to poor habits, such as rushing through brushing, skipping the space between teeth, missing dental appointments, smoking more, or reaching for sugary foods and drinks. These habits allow plaque to build up and increase the risk of tooth decay and gum disease.
Early gum disease, called gingivitis, can cause red, swollen, tender, or bleeding gums. It can often be reversed with good daily oral care and professional treatment.
Without treatment, gingivitis may develop into periodontitis, which damages the gums and bone supporting the teeth. Signs may include receding gums, persistent bad breath, and, eventually, loose teeth.
Dry Mouth Reduces Natural Protection
Stress, anxiety, and certain medicines can reduce saliva production and leave the mouth feeling dry.
Saliva protects the mouth by washing away food, neutralising acids, and strengthening tooth enamel. Without enough saliva, the risk of tooth decay, bad breath, mouth infections, and difficulty swallowing increases.
To relieve a dry mouth:
- Sip plain water throughout the day.
- Chew sugar-free gum to stimulate saliva, where appropriate.
- Limit sugary and caffeinated drinks.
- Avoid tobacco and excessive alcohol.
- Speak to a dentist or healthcare professional if dryness persists.
Never stop or change prescribed medicine without medical advice.
Mouth Ulcers Can Flare During Stressful Times
Stress may trigger recurring aphthous ulcers, commonly known as canker sores.
Most minor ulcers heal within a week or two, but an ulcer, lump, or red or white patch that lasts longer than three weeks needs a dentist or doctor’s attention and should never be dismissed as stress.
Protect Your Smile During Stressful Periods
Good oral care is especially important during stressful times:
- Brush twice a day for two minutes with fluoride toothpaste.
- Clean between your teeth daily with floss or interdental brushes.
- Limit sugary foods and drinks.
- Drink water regularly, especially if your mouth feels dry.
- Relax your jaw when you notice yourself clenching.
- Avoid chewing pens, biting your nails, or opening packaging with your teeth.
- Get enough sleep, exercise regularly, and find healthy ways to manage stress.
- See a dentist if you have tooth pain, bleeding gums, cracked teeth, or ongoing sensitivity.
