Different types of hard night guards

Make your impressions at home

Depending on the brand you pick, you may be able to customize the fit of your night guard. The following are the various night guards for bruxism:

  • One-size-fits-all: You may purchase over-the-counter mouth guards that are not custom-fitted. These are, undoubtedly, the most cost-effective solutions for the occasional teeth grinder.
  • Boil and bite: To make your own impression, just boil it in water and bite into it. It's typically rather straightforward to do and is inexpensive.
  • Order online: You may order nightguards from the comfort of your own home. You send your impression to the company you ordered from, and they give you a night guard that fits perfectly.
  • Night guards made in the dental lab: Mouth guards are available from your dentist. They provide the best possible fit because they are made in a lab using your impression.

It's one thing to consider the many kinds of fitting types. There are, however, also a variety of materials and structures to choose from.

Dual laminate night guards

A dual laminate night guard is also a harder type of night guard. However, the interior of a dual lamination night guard is soft, while the exterior is firm, providing extra protection and durability. 

It's a good alternative if you’re looking for maximum wearing comfort, but your teeth grinding is more severe and you want your night guard to endure longer.

Hard acrylic night guard

Another option is the hard acrylic night guard, also known as a hard plastic night guard. The hard acrylic night guard is much more durable than the soft night guard and other types.

Acrylic is a transparent, rigid plastic substance. This type is designed for people who grind their teeth often or severely. However, the acrylic night guard is not the same as an acrylic bite splint.

The acrylic biting splint is recommended to a patient to alleviate TMJ problems, while a standard hard acrylic night guard can help protect your teeth from damage through teeth grinding and clenching.

Because the hard acrylic night guard is constructed of a stronger material, it's essential to acquire a custom night guard that fits you exactly. The night guard may simply not fit onto the patient's teeth if the impression is not perfect. Custom night guards are also necessary if you need a night guard for braces.

Hard night guard cost

Your dentist will almost certainly recommend a harder night guard as a treatment option if you've been diagnosed with bruxism or TMJ disorder.

So, how much does a hard night guard cost you?

The cost of a harder night guard can vary greatly. The amount you need to spend depends on the severity of your bruxism and where you’re buying it.

Custom night guards cost $120 to $180 from internet retailers, a night guard from a dentist costs $300 to $900, and an over-the-counter night guard costs $20 to $30.

The quality and fit, on the other hand, differ substantially. An inexpensive night guard will not suffice if you're a heavy tooth grinder. You'll have to invest some money to get a high-quality night guard.

Hard night guards pros and cons



  • More durable

  • Prevents teeth from moving and shifting

  • Typically, it has a longer warranty

  • Can be uncomfortable

  • It can be more expensive

Are harder night guards the right choice for you?

Harder night guards are almost always the better choice, while soft night guards are only recommended in certain circumstances. They enable the bottom teeth to slip around easily. Furthermore, the soft ones may aggravate bruxism since the jaws naturally prefer to chew soft items.

Hard night guards vs. soft night guards

When comparing hard night guards vs soft night guards, there are benefits and drawbacks on both sides.

Hard night guards

Soft night guards

  • Durable

  • Long lifespan

  • Good for heavy grinders

  • Can be uncomfortable at first

  • More expensive

  • More comfortable

  • Cheaper

  • Heavy grinders will bite through them quickly

  • Can lead to more teeth grinding


You may still be unsure whether you should get soft or hard night guards. They both have some benefits and drawbacks. Unless you're just grinding once in a while, hard night guards are usually the best option.

If you grind your teeth a lot or usually wear a retainer, you should always pick a hard night guard that is as durable as possible.

If you're looking for a hard night guard that provides great comfort, while also giving you maximum durability because you grind your teeth a lot, we suggest Pro Teeth Night Guard.
