Pain that appears out of nowhere — no recent dental work, no injury, nothing you can point to. It's unsettling, but there's usually a clear explanation. Here's what might be going on and what to do next.
Cracked Tooth You Can't See
Hairline cracks in teeth are invisible to the eye and sometimes even to X-rays. They cause sharp, unpredictable pain — usually when biting or releasing pressure on food.
What to do:
- Avoid chewing on that side
- Note which tooth and what triggers it
- Book an appointment — we can test for cracks with special techniques
Cracks can worsen quickly if untreated, so don't wait.
Sinus Pressure Mimicking Toothache
The roots of your upper back teeth sit very close to your sinuses. When sinuses are inflamed — from a cold, allergies, or infection — it can feel exactly like toothache.
Clues it's sinus-related:
- Pain in multiple upper teeth, not just one
- Worse when bending forward
- Blocked nose or feeling of pressure
- Recent cold or hay fever
Try a decongestant. If the tooth pain improves, sinuses are likely the cause. If it doesn't, it's worth checking with us.
Grinding or Clenching (Bruxism)
Many people grind or clench without realising — especially during sleep or stress. This puts enormous pressure on teeth, causing:
- Generalised jaw aching, especially in the morning
- Sensitive teeth with no visible damage
- Headaches, particularly around the temples
- Wear patterns on tooth surfaces
What helps:
- A custom night guard (we can make one)
- Stress management
- Awareness of daytime clenching — lips together, teeth apart
Receding Gums Exposing Roots
As gums recede — from brushing too hard, gum disease, or ageing — tooth roots become exposed. Roots lack the enamel protection of the crown, so they're sensitive to temperature and touch.
Immediate relief:
- Apply Sensodyne Rapid Relief toothpaste directly
- Use a soft toothbrush with gentle pressure
- Avoid acidic foods and drinks temporarily
We can treat exposed roots with bonding or desensitising treatments.
Old Filling Breaking Down
Fillings don't last forever. Old amalgam or composite fillings can develop gaps, cracks, or decay underneath — causing pain that seems to come from nowhere.
Signs to watch for:
- Sensitivity that's gradually increasing
- A tooth that used to be fine now aching
- Visible dark areas around old fillings
A dental health assessment with X-rays will reveal if an old filling needs replacing.
