Night Guards: How They Protect Your Teeth and Relieve Dental Problems

Teeth grinding and jaw clenching are very common — especially at night, when you may not realise it’s happening. Over time, this can lead to worn teeth, headaches, jaw pain and broken dental work. At Glow Dental, we often recommend a custom-made night guard as a simple, effective solution that protects your teeth and helps relieve many long-term dental problems.

What Is a Night Guard?

A night guard (also called an occlusal splint) is a custom-fitted appliance worn over the teeth while you sleep. It acts as a protective barrier, absorbing pressure and preventing your teeth from grinding against each other.

A dentist-made night guard is:

• Precisely moulded to your teeth
• Comfortable and secure
• Designed to reduce muscle tension
• Long-lasting and durable

How a Night Guard Helps With Dental Problems

1. Prevents Tooth Wear and Damage

Grinding can flatten, chip, or crack teeth. A night guard cushions the biting surfaces and protects both natural teeth and dental work such as crowns, veneers and fillings.

2. Reduces Jaw Pain and TMJ Symptoms

Clenching strains the jaw joint, causing pain, clicking, stiffness and headaches. A professionally fitted night guard helps relax the jaw muscles and reduce pressure on the TMJ.

3. Helps With Headaches and Facial Tension

A night guard reduces overnight clenching, helping you wake up with less tension and discomfort.

4. Protects Orthodontic Work

If you’ve had braces, Invisalign, or restorative dental work, a night guard helps prevent damage and keeps your teeth aligned.

5. Supports Better Long-Term Oral Health

Grinding can cause gum recession, loose teeth, and enamel fractures. A night guard prevents these long-term complications and helps maintain a stable bite.

Why Choose a Custom Night Guard From Glow Dental?

At Glow Dental, we use high-quality materials and precise digital impressions to create night guards that are:

• Thin, smooth and comfortable
• Tailored to your bite and jaw position
• Strong enough for heavy grinders
• Designed to reduce muscle tension

When You Should Consider a Night Guard

You may benefit from a night guard if you experience:

• Worn teeth
• Jaw pain or clicking
• Morning headaches
• Tooth sensitivity
• Cracked or chipped teeth
• Facial muscle tension
• Signs of grinding at night

Can night guards cause cavities?

Night guards themselves do not cause cavities, but poor cleaning habits can. If a guard is not cleaned properly, bacteria can build up on the surface and sit against the teeth overnight. This increases the risk of decay, gum irritation, and bad breath. To avoid this, rinse your night guard before and after use, brush it gently with a soft toothbrush, and keep it stored in a clean, ventilated case. Regular hygiene appointments also help keep your teeth protected while wearing a night guard.

If you’re unsure, our dentists can spot early signs during a routine check-up.
