What Is a Night Guard and Why Do You Need One?
If you grind or clench your teeth while you sleep—a condition known as bruxism—you may be putting serious stress on your mouth. Night guards act as a protective barrier between your upper and lower teeth, preventing damage like:
- Tooth fractures or chipping
- Enamel erosion
- Gum recession
- Jaw pain and TMJ discomfort
- Headaches and poor sleep
The right night guard can protect your smile and reduce strain on your jaw muscles, letting you wake up pain-free.
Over-the-Counter (OTC) Night Guards – What You Need to Know
What Are OTC Night Guards?
OTC night guards are pre-made, mass-produced products sold at drugstores or online. Some can be boiled and molded at home ("boil-and-bite" style), while others are ready-to-wear.
Pros of OTC Night Guards
- Low upfront cost – Typically $20–$50
- Immediate availability – Pick one up today and wear it tonight
- No dental visit required
Cons of OTC Night Guards
- Poor fit – One-size-fits-all doesn’t match individual mouths
- Bulky and uncomfortable – May interfere with breathing or speech
- Short lifespan – Materials wear down quickly
- Limited protection – Not ideal for moderate to severe bruxism
- Can cause bite misalignment if not molded properly
OTC night guards are best for short-term use or light grinding. If your symptoms are worsening or long-term, they may not offer the support you need.
Custom Night Guards – The Dentist-Grade Alternative
What Are Custom Night Guards?
Custom night guards are tailored to your mouth using an impression or scan of your teeth. They’re made in a lab, using high-quality materials that match your grinding severity and jaw structure.
Pros of Custom Night Guards
- Perfect fit – Built to your unique bite and dental profile
- More comfortable – Slimmer and less intrusive than OTC options
- More effective – Greater protection against grinding/clenching
- Longer lifespan – Durable materials last 1–5 years depending on usage
- Better jaw alignment – Reduces tension and TMJ-related pain
Cons of Custom Night Guards
- Higher initial cost – Dentist-provided guards may cost $400–$800
- Requires dental visit – If bought through a clinic
- Takes time to receive – Typically 1–2 weeks for delivery
However, online providers like DentalNightGuard offer the same custom quality without the dental visit—saving you both time and money.
