Do you ever wake up with a sore jaw, sensitive teeth, or headaches? You may be one of the many New Zealanders who grind their teeth at night without realising it. Known as bruxism, night-time grinding and clenching is more common than most people think—and the long-term effects can be costly for both your smile and overall well-being.
At Howick Dental Surgery, we regularly see patients across East Auckland who are experiencing dental damage linked to bruxism. Understanding the signs early—and knowing how a custom night mouth guard can help—can save you from discomfort, dental complications, and expensive treatments later.
Why Do People Grind Their Teeth?
Night grinding can be caused by several factors, including:
- Stress and anxiety– One of the most common triggers among adults in New Zealand
- Sleep issuessuch as snoring or sleep apnoea
- Bite alignment problems(malocclusion)
- Lifestyle factorslike caffeine, alcohol or smoking
- Medicationsthat affect muscle tension or sleep patterns
Children and adults can both be affected, although adult bruxism tends to be more damaging due to stronger bite force.
The Hidden Costs of Night Grinding
Many Kiwis don’t address bruxism until the symptoms become hard to ignore. Left untreated, night grinding can lead to:
Tooth Wear and Cracks
Constant grinding can flatten tooth surfaces, weaken enamel, and cause micro-fractures. Once enamel is worn down, it cannot regenerate.
Jaw Pain & TMJ Disorders
The pressure from clenching can strain jaw joints, causing clicking, locking, tenderness and chronic pain.
Headaches and Poor Sleep Quality
Morning headaches, neck tension and disturbed sleep are common side effects.
Increased Dental Bills
Repairing cracked or worn teeth may require fillings, crowns, root canals or even extractions. Many patients later spend thousands on restorative care that could have been prevented.
Tooth Sensitivity
- Worn enamel leaves teeth vulnerable to hot and cold temperatures.
- The reality is simple: ignoring bruxism is far more expensive than preventing it.
How a Night Mouth Guard Can Save Your Smile
- A custom-fitted night mouth guard,also known as a dental night guard, is one of the easiest and most effective ways to protect your teeth from grinding.
At Howick Dental Surgery, we create professional mouth guards shaped to your exact bite, offering:
Protection from Tooth Wear
The guard acts as a cushion, absorbing grinding forces and preventing enamel damage.
Reduced Jaw Strain
A properly fitted guard helps your jaw muscles relax during sleep.
Better Sleep
Many patients report waking up with less tension, fewer headaches and improved sleep quality.
Long-Term Cost Savings
Preventing damage now means avoiding costly dental procedures later.
Unlike over-the-counter guards, a dentist-made guard fits securely, feels comfortable, and provides superior protection suited to your bite pattern.
When Should You See a Dentist?
If you notice symptoms like jaw tightness, tooth sensitivity, chipped teeth, facial soreness, or waking with headaches, it’s time to get assessed. Early intervention can prevent long-term damage.
