The 5 Best TMJ Mouth Guard Options

When choosing a TMJ mouth guard you need to find one that is comfortable as well as easy to clean, and it should be capable of limiting your teeth grinding to the extent that your temporomandibular joint pain really is decreased.  The 5 mouth guards below all qualify as excellent mouth guards, and all fall squarely into the affordable category for most people.  That means you won’t have to trade an arm and a leg just to get the relief you want from chronic TMD pain.

Armor Guard Pro-form Night Guard

Unlike the common boil-and-bite “custom-fit” mouthpieces made of thermoplastic, this night guard is still manufactured in a professional factory and by experts.  Where the custom fitting does come in is that the company sends you an impression kit before they create your mouthpiece.  The kit is mailed back, and a customer service rep calls the customer for a consultation to determine the ideal characteristics and rigidity for the finished product, then the mouthpiece gets made and is mailed back to the customer.


  • Cheap for a custom-fit professionally made guard
  • Great customer service
  • Customers given choices for hard/soft mouthpieces


  • Still pricy when compared to boil-and-bite guards

While boil-and-bite mouthpieces have come a long way, they still do not quite measure up to the professionally produced custom-fit ones when the latter are done well.  Where Armor Guard really stands out is in its remarkably low pricing at roughly $80, which includes shipping costs.

Few companies provide the same level of personalization Armor Guard does, which gives it a real edge in the market.  There is also the fact that you can choose a softer, more cushion-like mouthpiece material if you prefer it: this is something you can’t do with most other mouth guards.

Silent Sleep Teeth Mouth Guard

The Silent Sleep Teeth Mouth Guard is crafted out of thermoplastic and can be softened in hot water as a preparation for molding.  This full-mouth guard also comes bundled with a dedicated storage case.


  • Very cheap
  • Molds well
  • Shorter than most other guards, so it won’t cause a gag reflex in most people


  • Can still feel a little bulky for some people due to the full-mouth design

This is a cheap mouth guard (you can get it for less than $14) that delivers quality above its price.  It’s fairly easy to mold and relatively comfortable in the mouth, especially because of the slightly shorter shape compared to most other full-mouth guards.  Even those with a tendency to gag on their mouthpieces will be unlikely to do that on this one.  While this is advertised primarily as an anti-snoring aid, it seems to perform even better for TMD treatment.

Smartsmile Professional Nightguard for Bruxism

This package comes with 2 moldable mouthpiece trays that can be molded to the shape of your gums and teeth before being used.  They sport bite pads that retrain the mouth and jaw into a more relaxed position, rendering biting less comfortable.


  • Comes with 2 trays in case you do the molding wrong
  • Quite comfortable when molded right
  • Tends to stay in place well


  • May result in drooling during sleep for some people

This is a great sub-$30 mouthpiece that comes with 2 trays in the package—something really useful given how many of us tend to flub the molding process.  It’s comfortable enough to sleep with and isn’t prone to falling out of your mouth at night.  That said, some will also find it makes them super saliva factories when they’re sleeping.  You may want to try it out first to see if it does that to you.

Mouth Guard from ProDental

This 3-in-1 mouth guard can be trimmed to better fit your mouth and can be used to prevent bruxism, deal with TMJ disorder issues, whiten your teeth, and protect your teeth during physical activity.  It is made of soft and moldable polyvinyl.


  • Comes with 3 guards in the package
  • Soft, comfortable plastic
  • Fairly easy to mold


  • Will need trimming for most people

This mouth guard costs about $30 for 3 pieces, which isn’t bad at all considering each one comes out to just $10.  It molds easily and actually feels a little softer than other mouth guards.  That can be a good thing or a bad thing depending on how much force you exert when grinding your teeth. There’s also quite a lot of material to it, so you may need to trim it to avoid gagging or to make space for your tongue in your mouth.  Still, it feels very comfortable when trimmed and molded right, so that extra step shouldn’t bother most people.

DenTrex Mouth Guard

This soft silicone mouth guard has 4 breathing holes for easier sleep and also has a shock-absorbent Air Spring base.  The flexible plastic forms to your mouth without the need for boil-and-bite molding.


  • Soft plastic
  • No need for boiling and biting
  • Cheap


  • May be big for a lot of people

This can be a pretty big mouthpiece, but it can be trimmed easily to prevent you from gagging or drooling excessively with it in.  It’s pretty nice quality for something that only costs about $14 and also feels nice and comfortable if you shape it right and get used to it.  Some people won’t ever really accustom themselves to the way it feels though, so it may not work for everyone.


The best mouth guard of the lot is the Armor Guard due to its professional-quality fabrication.  Yes it costs more than the rest, but it still costs a pittance you when compared to what you would pay for a custom-made guard from a dentist.  If you really can’t shell out the cost of the Armor Guard mouthpiece though, any of the other guards in this list should do fine.  They are all highly similar anyway and should give you good quality at a low price.
