Night guards play an important role in protecting teeth and dental restorations from excessive forces caused by grinding or clenching.

They are commonly recommended both to prevent damage and to protect dental work that has already been carried out.

Why are night guards needed?

Many people grind or clench their teeth without being aware of it, particularly during sleep. Over time, this can lead to:

  • Tooth wear.
  • Cracked or broken teeth.
  • Failure of fillings, crowns, or veneers.
  • Jaw or muscle discomfort.
  • Headaches or facial pain.

A night guard acts as a protective barrier, reducing stress on teeth and restorations.

FAQ

FREQUENTLY ASKED QUESTIONS

When is a night guard recommended?

A night guard may be advised if you:

  • Have signs of tooth wear.
  • Grind or clench your teeth.
  • Have repeated breakage of dental work.
  • Have had bite changes or complex restorative treatment.
  • Have dental implants or implant restorations.

In many cases, it is a preventive measure rather than a response to symptoms.

How does a night guard work?

A custom-made night guard:

  • Fits precisely over your teeth.
  • Helps distribute bite forces evenly.
  • Reduces direct tooth-to-tooth contact.
  • Protects both natural teeth and restorations.

It does not stop grinding, but it significantly reduces the damage caused by it.

Are night guards a standard size?

No, night guards are tailored to the individual and may vary depending on:

  • Bite relationships.
  • Tooth wear patterns.
  • Type of dental restorations present.

Your dentist will recommend the most appropriate design for your situation.

How to care for your nightguard?

Wearing and caring for your night guard instructions:

  • Wear the guard as advised, usually at night.
  • Clean it daily with a soft brush and cool water.
  • Avoid hot water.
  • Store it in its case when not in use.
  • Bring it to the review appointments for checking.

Night guards may need adjustment or replacement over time.

When is a night guard recommended?

Night guards after restorative or complex treatment

After treatment involving crowns, veneers, bonding, implants, or bite changes, a night guard is often recommended to:

  • Protect restorations.
  • Maintain bite stability.
  • Reduce the risk of fracture or wear.
  • Improve longevity of treatment.

This is especially important in patients with a history of tooth wear.
