What Causes Bruxism?


Possible causes of bruxism


Oral health professionals frequently attribute bruxism to excessive stress, anxiety, anger, frustration, or tension [1]. Bruxism may also occur due to upper respiratory airway obstruction caused by sleep apnea [2].

Like many other conditions, Bruxism varies in severity, and while very mild cases may not necessitate professional care, others do. Consequently, it is important to distinguish between two basic types of bruxism, each of which may require a distinct treatment strategy.


Awake Bruxism

Awake bruxism, also referred to as daytime bruxism, is less prevalent and slightly easier to identify and treat. Teeth clenching or grinding when awake is especially common during bouts of concentration, anger, or stress, and it typically occurs without a person’s awareness.


Sleep Bruxism

The most common type of teeth grinding occurs mostly at night while sleeping. You might not realize you have it unless a family member or bed partner hears the noise. Sleep bruxism affects 8% of the general population, with no gender differences [3].

When people are awake, they may notice the following signs and symptoms of nocturnal bruxism:

  • Pain in the facial muscles.
  • Tired or tight lower jaw muscles.
  • Headache.
  • Sensitive, loose, or broken teeth.
  • Abraded or worn-down teeth.


How Do Night Guards Protect Teeth?

A dental night guard protects the teeth from damage by dampening the impact of clenching the teeth while sleeping. This cushioned barrier helps to prevent worn-down or chipped teeth, which are two of the most typical effects related to the act of clenching one’s teeth, from occurring.


Do OTC Mouth Guards Work? 

While getting a proper fit with an OTC mouth guard can be challenging for some people, wearing an over-the-counter dental guard to protect your teeth from grinding or clenching when sleeping is preferable to having no protection at all.

Even if you decide to invest in a custom-fit mouth guard from your dentist, an over-the-counter one may be a viable alternative while you wait for your custom night guard to be completed.

3 Types of Over the Counter Night Guards 

There are three types of over-the-counter mouth guards for teeth grinding:


3 Types of Over the Counter Night Guards


  1. One size fits all.
  2. Boil and bite.
  3. Mail-in custom fit.


One Size Fits All

These are the pre-formed, ready-to-wear over-the-counter mouth guards for teeth grinding. Also known as stock mouthguards, they are usually one size fits all and relatively inexpensive. Orthodontists may recommend this type since it protects delicate tissues while allowing for tooth mobility.


Boil and Bite

Fitting your boil and bite dental guard is a simple and straightforward process and appears to be the most prevalent form available. All it takes with this type is to submerge it in hot water to soften and then place it in the mouth and shape it around the teeth. Boil and bite mouth guards offer a better fit than stock mouth protectors.


Mail-in Custom Fit

You can also order custom mouth guards for teeth grinding from the comfort of your own home. The company you choose will send you a complete, easy-to-use home kit for taking your teeth impressions. Following that, they will mail you back your custom mouthguard.


What to Look for When Choosing a Night Guard

Whether you choose a custom mouthguard that you mail away, a simple boil-and-bite guard, or a professional dental guard fitted in person by your dentist, a night mouth guard protects your teeth from damage by creating a physical barrier between your upper and lower teeth.

Here are some points to consider when choosing among the numerous night mouth guard alternatives accessible to you.



You can have your nighttime dental guard manufactured out of see-through plastic to make it nearly undetectable, or you can have it made in any color you like. Most mouth guards are placed over the upper teeth, but you may want a lower guard as well.



People have recently become more aware of the potentially dangerous compounds included in a wide range of plastic products, such as latex, BPA, and phthalates [4].

You might be concerned that these chemicals are in the dental gadget you’ll be using every night, especially since grinding can cause wear and tear on the plastic. If so, you want to look for non-toxic, FDA-approved, and professional dental industry material when purchasing a night guard.



If your nighttime grinding is severe enough that your dentist has prescribed a nighttime dental guard, you may be in danger of regularly wearing it out. Consult your dentist to determine the severity of your problem and whether you’ll require an extra-durable dental guard.



The more at ease you are with your night guard, the more likely you are to wear it. Your mouth guard, on the other hand, should never make you pick between comfort and protection. Both should be included.



If price is a major consideration, it may be tempting to get the cheapest mouth guard you can find. This approach, however, may end up costing you more in the long run by worsening existing issues such as shifting teeth or jaw misalignment. Orthodontic treatments to straighten teeth typically range anywhere from $3,500 to $7,500, depending on the severity of the case. 


Are Over the Counter Night Guards Bad for Your Teeth? 

At best, an over-the-counter dental guard can act as a stopgap measure, preventing further tooth damage while the wearer awaits competent dental or medical care to ascertain the underlying causes of their bruxism.

At worst, an over-the-counter mouth guard may be a factor in exacerbating pre-existing issues, such as TMJ and teeth misalignment, necessitating more extensive treatment once the individual visits the dentist.


Dental Night Guard Side Effects

While off-the-shelf teeth grinding mouth guards use a plastic thin material, many people find it too thick to sleep comfortably with. Other drawbacks of OTC mouth guards include:


Drawbacks of over the counter mouth guards


  • Not able to provide a snug and secure fit.
  • Not provide you with optimal protection.
  • They may only stay in place when you close your mouth.


Advantages of OTC Night Guards

In many cases, relief from the pain and potential dental damage associated with night grinding cannot wait the week or two required to create a custom-made dental guard. Off-the-shelf nighttime dental guards can be fitted in less than three minutes in the comfort of your own home.

An OTC mouth guard is also much cheaper in comparison to visiting your dentist for a pro teeth guard.


Consult Your Dentist Before Using Over the Counter Night Guards

While there are many over-the-counter night guards available, every mouth size and shape is different. To make sure you have the device that is right for you, it is recommended that you discuss your options with your dentist. Then you may be confident that you are making the best decision for your dental needs.



Listed here are the answers to some of the most frequently asked questions regarding over-the-counter mouth guards.


Can a Night Guard Change Your Bite?

Which Night Guard Is Better?

Do Over-the-Counter Mouth Guards Work for TMJ?

Which Night Guard Is the Best for Teeth Grinding?

Can Night Guards Ruin Your Teeth?



Finding the best mouth guard for teeth grinding is difficult. The aforementioned over-the-counter mouth guards are effective, versatile, and long-lasting.

Consider factors such as the shape of your jaw or teeth to determine whether you require a custom made or conventional dental guard before selecting the best dental guard. Ideally, make an appointment with a dentist to address the source of your problem.
