If you grind or clench your teeth at night, you've likely wondered whether it's safe to wear a night guard every single night. The short answer is yes. When well fitted and cared for, night guards are designed for nightly use and play an important role in shielding your teeth from grinding-related pressure. In this guide, we'll explore the benefits, potential downsides, and what to expect from long-term use, so you can make an informed decision about your nightly routine.
Are Night Guards Safe to Wear Every Night?
Night guards are safe to wear every night when they fit correctly and are kept clean. Nightly wear is not only common—it’s often necessary for people who grind or clench their teeth regularly. The purpose of a night guard is to act as a cushioning layer between your upper and lower teeth, absorbing and distributing the forces generated during grinding episodes. This helps safeguard your tooth enamel, fillings, crowns, and other dental work from excessive wear and potential damage.
The key to safe nightly use is ensuring your guard fits snugly without causing discomfort, and that you follow a consistent cleaning routine. A well-fitted, well-maintained night guard becomes a seamless part of your bedtime routine, much like brushing your teeth.
If you're looking for a reliable option for nightly protection, the OPRO Night Guard is a self-fit, boil-and-bite night guard designed specifically for regular use.
Benefits of Wearing a Night Guard
Wearing a night guard each night provides consistent protection against grinding-related wear. It cushions your teeth and helps maintain dental work without disrupting your sleep routine.

Possible Downsides and How to Avoid Them
Fit Matters
An ill-fitting night guard can cause discomfort, irritation to your gums, or even shift your bite over time. The good news is that most fit issues are preventable. With a boil-and-bite guard, it's essential to follow the self-fit instructions carefully—heat the guard to the correct temperature, mould it precisely to your teeth, and allow it to cool completely before removing it. If the fit isn't right the first time, many guards can be remoulded. Take your time with this step, as a proper fit is the foundation of safe, comfortable nightly use.
Cleaning and Storage
Clean your guard daily with cool water and mild soap, then let it dry before storing. For full care instructions, see our Night Guards for Teeth Grinding guide.
Replacement Cadence
Like any oral-care product that experiences regular wear, night guards have a limited lifespan. The typical replacement timeframe is around three months under normal nightly use, though heavy grinders may need to replace theirs sooner. Watch for signs of wear such as thinning, tears, or rough edges, and replace your guard promptly when these appear. Continuing to use a worn guard reduces its protective effectiveness and can harbour bacteria. To make regular replacement easy, OPRO offers a 4-Pack of Night Guards – buy four and get a free UV Cleaning Case, ensuring you always have a fresh, hygienic guard ready to use.
Not for Fixed Braces
If you currently have fixed braces, a boil-and-bite night guard is not suitable. The brackets and wires interfere with the moulding process and fit. If you wear braces and experience grinding, speak with your orthodontist about appropriate protective options during treatment.
Long-Term Use: What to Expect
The protective benefits of wearing a night guard build over time. By consistently shielding your teeth from grinding forces night after night, you help preserve your enamel, maintain the integrity of dental work, and potentially avoid costly repairs down the line. Long-term success depends on three factors: maintaining a proper fit, keeping up with daily hygiene, and replacing your guard at the recommended intervals.
It's also wise to schedule periodic dental check-ups—typically every six months—so your dentist or hygienist can monitor your overall oral health, check for signs of bruxism, and ensure your night guard routine is working well for you.
