What Makes Professional Nightguards Preferred vs. Over-the-Counter Appliances?

Nightguard lying in its case.

If you suffer from bruxism, meaning you grind or clench your teeth while you sleep, your dentist may recommend wearing a nightguard to protect both your teeth and jaw joints. When you see the price difference between a professional, custom-made nightguard and an over-the-counter (OTC) option, you may question whether the investment is really worth it.

While an OTC nightguard can be convenient and inexpensive, a professional appliance offers several advantages that may make it a better long-term choice for protecting your smile. Let’s explore a few of them!

A Custom Fit Provides Better Comfort

One of the biggest benefits of a professional nightguard is its customized fit. Your dentist can use impressions or a digital scan of your teeth to create an appliance designed specifically for your mouth.

On the other hand, store-bought nightguards are mass-produced and designed to fit a wide range of people. Some can feel bulky, shift during sleep, or interfere with your bite.

A properly fitted nightguard should feel secure and comfortable enough to wear consistently. If an appliance is uncomfortable, you’re less likely to use it regularly, which defeats much of its purpose.

Your Dentist Can Consider Your Bite

Teeth grinding and clenching don’t affect everyone in the same way. The amount of pressure you generate, your bite, existing dental work, and the condition of your teeth can all influence which type of nightguard is appropriate.

When your dentist creates a custom appliance, they can evaluate your bite and design the nightguard accordingly. They can also make adjustments if necessary.

This personalized approach can be particularly valuable if you have crowns, veneers, bridges, dental implants, or significant tooth wear.

Greater Durability

If you grind heavily, you can put considerable force on a nightguard. Some inexpensive appliances may wear down or become damaged relatively quickly.

Professional nightguards are typically made from materials selected for durability and your specific needs. Although the initial investment may be higher, a durable appliance can provide reliable protection and potentially last longer.

Your dentist can also monitor the condition of the nightguard during routine appointments and let you know when it needs to be replaced.

A Nightguard Can Protect More Than Your Teeth

Untreated nighttime grinding can not only contribute to chipped or cracked teeth, worn enamel, and tooth sensitivity, but also cause morning headaches and soreness in the jaw and neck. It can also damage expensive dental restorations that you’ve sunk your hard-earned money into.

A nightguard won’t necessarily stop you from grinding, but it does create a protective barrier between your upper and lower teeth and helps reduce the damage that can result from bruxism.

An over-the-counter nightguard may look like an attractive short-term solution, but a custom appliance offers the benefits of personalized fit, professional evaluation, and potentially greater durability. When it comes to your oral health and overall well-being, a quick fix rarely produces desirable long-term results.
