Sentinel Mouthguard: Best for daytime wear

Sentinel has been in the mouthguard business for over 30 years and has a trusted reputation. They offer five guard options for teeth grinding and clenching, including a hard, no-show day mouth guard. This solves the problem for people who don't only suffer from bruxism or clenching at night, but also during the day.

These guards are cut down in the front, so none of your front teeth are covered by the guard, meaning total discreetness. And for chronic cheek biters, Sentinel also offers tongue and cheek-biting relief guards made especially to protect your soft oral tissue.

Dentek Dental Guard: Best over-the-counter night guard

  • Fitting tray

  • Antimicrobial case

The instructions are easy to follow:

  • Rinse your dental guard in warm water
  • Place it over your lower teeth and bite down
  • Continue to adjust as needed

One set should last for 6 months with proper care.

Different types of night guard

Of the night guards mentioned above, Smile Brilliant, Sporting Smiles, and Sentinel are all custom-made night guards, and Dentek is an over-the-counter adjustable guard. Each person will have different treatment needs when it comes to protecting teeth from grinding at night. What may work for one person may not be the best option for another.

Below we go over the basics of each kind:

Custom-made mail-order guards

Make your impressions at home

These include the Smile Brilliant mouth guards that we first mentioned. You order an impression kit online to make your mold impressions at home. Next, you send the impressions to the dental technicians who will make your night guards in a dental lab.

Once they are made, you'll get them shipped to your home, and you can start wearing them. Companies like Cheeky night guards usually keep your fit information record. This makes it easier to reorder more when you need them.

Adjustable night guards

These are made of a more flexible material. You can continue to adjust them to your mouth after warming them in warm (not hot or boiling) water. You can do this repeatedly until you get your desired fit.

Boil-and-bite night guards

These require you to boil them in water and then bite down on them to fit them into your mouth. Once you bite down and the guard has cooled, you won't be able to adjust them any further.

One-size-fits-all night guards

This is the least ideal style of night guards. There is a higher chance that they won't fit your teeth. This can cause discomfort when you wear them, potentially affecting your sleep. For some people, these do work and certainly have a cheaper price tag.

How to choose the best night guard for teeth grinding

There's a lot to keep in mind when you're considering which night guard to purchase. You'll need to think about the materials, comfort, instructions for use, durability, and of course, value for the price. Let's have a look at some of the main factors in this decision:

  • Fit: A precise fit is extremely important, considering that you'll need to be able to wear your mouth guard at night without noticing it or feeling bothered by it. Many people opt for custom mouthguards instead of one-size-fits-all or the type you need to fit at home.
  • Comfort: This will depend on the materials used, the fit, and the mouthguard style. Mouthguards that are professionally made to fit your teeth will be the most comfortable.
  • Style: There are various styles of night guards for teeth. These include some that are fitted to your teeth at a dental lab, one-size-fits-all models, or models that you fit at home either by boiling and biting or by adjusting a soft, flexible mold.
  • Durability: The best quality mouth guard for grinding teeth will also be the most durable. But keep in mind that this doesn't necessarily mean the length of time they last before breaking, nor the thickness, but rather how long they can effectively protect your teeth from grinding. This will also depend on the severity of your bruxism. Heavy teeth grinders will have to replace their devices more frequently. This is why we recommend going with a brand like Smile Brilliant, which keeps your teeth impressions on file so you can easily order a replacement when needed.
  • Price: Purchasing your dental guard on Amazon will be cheaper than buying it from your dentist or ordering custom-fitted night guards from a professional dental lab. However, for many people, the better fit, increased comfort, and higher level of efficacy are well worth a higher price tag.

It is important to avoid partial coverage mouthguards that do not fully cover the maxillary and mandibular occlusion. A study comparing OTC splints shows that these partial splints may cause tooth movement. Therefore, only use them at your dentist's recommendation.

How do custom-fit night guards work?

Custom-fit night guards are the best option in terms of comfort, fit, and function. And if you order one online, you'll pay much less than you would at the dentist. Here's how it works:

  • Order your impression kit: Go to the site of your choice and select the night guards you want. You'll receive your impression kit in the mail and make your dental impressions at home. You'll then send your impressions to the lab in the included prepaid envelope.
  • The lab custom-makes your devices: Once the lab receives your impressions, they will craft your mouthguards to the exact fit of your teeth and finish them for maximum comfort and effectiveness.
  • Wear your teeth guards: You'll receive your tailor-made mouth guard for sleep in the mail so you can start protecting your teeth right away. Typically, your dental impressions are kept on file with the company, so they're easy to reorder when it's time to replace them.

Do I need a mouthguard for grinding teeth?

If you're unsure whether you need a mouth guard, visiting your dentist is a great place to start. Your dentist will check your teeth for signs like enamel erosion, chips, or worn-down teeth. Other indicators that you grind your teeth at night could be chronic neck and lower jaw stiffness and toothache.

Tooth grinding can cause irreversible damage to your teeth if it persists. Also, clenching your teeth can cause them to chip and fracture. Determining the root cause of bruxism is important in considering the best approach to deal with it. As it could be primary or secondary, it could be a side effect of another medication.

Other conditions like stress, certain neurological conditions, and other medications may also contribute to the grinding and clenching of teeth. Smoking and alcohol consumption won't help, either. You might also experience bruxism after getting braces, so you'll need a night guard for braces.

Your dentist can help you identify the root cause and recommend the appropriate treatment to halt grinding your teeth altogether.

The video below shows you how to recognize the indicators that you may be a nighttime tooth grinder:

Many people toss and turn at night. Some people may snore, while others have restless legs but there’s another habit that is much more detrimental to your health. Teeth grinding is a side effect of anxiety and stress where your body releases it through the act of grinding your teeth. It can leave permanent damage that needs expensive repairs.

Should a night guard shift your teeth?

You shouldn't feel jaw pain after wearing your
mouthguard at night

No, a night guard shouldn't move your teeth at all. The purpose is to protect your teeth from grinding and clenching while you sleep. If you suspect that your mouthguard may be shifting your teeth, you should discontinue use immediately.

You may be able to tell if a night guard is moving your teeth if you experience tightness or discomfort when wearing it or right after putting it in.

The best way to avoid this problem is by purchasing custom bruxism mouthguards instead of cheaper, one-size-fits-all options.

How do you clean a night guard?

You can clean your night guard with your toothbrush and toothpaste. You can also rinse it with soap and water, clean it with vinegar, or use a denture cleaner. Make sure to read the cleaning instructions by your mouthguard makers to avoid damage.

Why do my teeth hurt after wearing night guards?

Your teeth may hurt after wearing a night guard as a result of size and thickness mismatch. This is most common in one-size-fits-all mouthguards since they aren't designed specifically for your teeth.

If you experience tooth or jaw pain after wearing this type of night guard, discontinue use immediately. Talk to your dentist about getting custom-fitted bruxism mouthguards. Your dentist should also check for other oral health problems that may be causing the pain.
