how long do night guards last

Night guards, also known as mouthguards or occlusal splints, are custom-made or over-the-counter devices designed to protect your teeth from grinding (bruxism) and clenching. But how long can you expect your night guard to last? The lifespan of a night guard depends on several factors, and understanding these factors is crucial for maintaining its effectiveness and protecting your oral health.

How Long Does a Custom-Made Night Guard Last?

Custom-made night guards, crafted by a dentist based on impressions of your teeth, generally last 2-5 years. However, this is just an average. The actual lifespan can be shorter or longer depending on several key elements. Proper care is absolutely paramount.

Factors Affecting the Lifespan of a Custom Night Guard:

  • Material: The material used significantly impacts longevity. Harder materials like acrylic are more durable than softer materials.
  • Bruxism Severity: If you're a severe grinder, the wear and tear on your night guard will be more rapid.
  • Care and Maintenance: Regular cleaning and proper storage significantly extend the lifespan.
  • Oral Hygiene: Maintaining good oral hygiene practices prevents bacterial build-up and damage.
  • Mouth Breathing: Excessive mouth breathing can dry out the night guard, making it more prone to cracking.
  • Accidental Damage: Dropping or biting down too hard can cause damage.

How Long Does an Over-the-Counter Night Guard Last?

Over-the-counter (OTC) night guards are readily available at pharmacies and online stores, offering a more affordable option. However, their lifespan is generally shorter, typically lasting 6-12 months. The lower cost reflects the less durable materials and simpler manufacturing process.

Factors Affecting the Lifespan of an OTC Night Guard:

  • Material: OTC night guards are usually made from softer, less durable materials, making them prone to faster wear and tear.
  • Fit: The fit of OTC night guards can be less precise than custom-made ones, leading to uneven wear and faster deterioration.
  • Usage: Frequent use and aggressive grinding will shorten the lifespan.

How Often Should I Replace My Night Guard?

Regardless of whether you have a custom-made or OTC night guard, it's crucial to replace it when it shows signs of significant wear and tear. This includes:

  • Cracks or Chips: Any cracks or chips compromise the protective function and can harbor bacteria.
  • Significant Wear: If the night guard is significantly worn down, it won't offer adequate protection.
  • Changes in Fit: If the fit becomes uncomfortable or doesn't feel right anymore, it's time for a replacement.
  • Discoloration: Persistent discoloration may indicate bacterial buildup that's difficult to remove.
  • Regular Check-Ups: Discuss the condition of your night guard with your dentist during your regular checkups.

What Happens If I Don't Replace My Night Guard?

Using a worn-out night guard can lead to several problems:

  • Reduced Protection: A damaged night guard will not effectively protect your teeth from grinding and clenching.
  • Increased Risk of Tooth Damage: This can lead to tooth sensitivity, enamel wear, fractures, and jaw pain.
  • Bacterial Growth: Worn areas can trap bacteria, potentially leading to gum disease.
  • TMJ Problems: Continued grinding can exacerbate temporomandibular joint (TMJ) disorders.

How Can I Extend the Life of My Night Guard?

Taking good care of your night guard is essential to maximizing its lifespan:

  • Clean it daily: Brush it gently with a soft-bristled toothbrush and mild soap.
  • Rinse thoroughly: Rinse it well after each use to remove saliva and debris.
  • Soak occasionally: Soak it in a denture cleaning solution according to the manufacturer's instructions.
  • Store it properly: Store it in a dry, clean case when not in use.
  • Avoid extreme temperatures: Do not expose it to extreme heat or cold.
  • Avoid chewing on hard objects: This can cause damage and premature wear.

Can I Repair a Damaged Night Guard?

Minor cracks or chips might be repairable by a dentist, but this is not always the case. If your night guard is significantly damaged, replacing it is generally the best option to ensure adequate protection.

By understanding the factors that influence the lifespan of night guards and following proper care instructions, you can ensure you're getting the most out of your investment while protecting your oral health. Remember to consult your dentist for advice tailored to your specific needs and situation.
