Am I a candidate for a custom night guard?

YES, if...

  • You have frequent head/neck/shoulder tension
  • You have jaw pain and/or difficulty opening your mouth
  • You have tooth sensitivity
  • The edges of your teeth are chipped, cracked, or worn down
  • You were told by a dentist that you need one

NOTE: OTIS Custom Night Guards are for those with mild-moderate Bruxism. If you have multiple restorations, loose teeth, have pending dental treatment, and/or over 50 years of age, we highly recommend that you consult a dentist before ordering an OTIS Custom Night Guard, and request assistance with the impression-taking process.

OTIS vs. OTC (over-the-counter)?

We live in a world of diverse lifestyles and diets that result in unique bruxing habits. OTIS custom fit night guards effectively protect against an individual's unique jaw and tooth stress — providing protection and relief throughout the night. Over-the-counter guards are made in a one-size-fits-all design with lesser quality materials. As a result, you're likely to wear down the guard in a few weeks and/or not be able to wear it throughout the night because of its uncomfortable fit.

OTIS vs. Dentists?

With OTIS you pay 70% less than what you'd pay at the dentist for the same quality dental products. OTIS offers custom night guards directly to you, so you never have to visit your dentist to get one.

Is the quality of your products the same as my dentist?

YES – we use the same quality materials and fabrication processes as other dental labs. The truth is, over 90% of dentists get their night guards made from dental labs, like ours.

When you purchase an OTIS product, you’re getting quality, convenience and affordability that is backed by a team of licensed dental professionals with over 70 years of combined experience in general dentistry, dental hygiene and engineering.

How do I know if I need an upper or lower night guard?

A majority of customers prefer an upper night guard because it sits more comfortably on the upper arch of teeth and won't get in the way of the tongue. However, a lower night guard may be best if any of your upper teeth are missing and/or, if you have pending dental treatment (e.g., crowns or implants). When in doubt, consult with a dentist first.

Can I use my dental insurance, FSA or HSA?

Yes - we do accept FSA and HSA payments!

For dental insurance reimbursements, we cannot submit claims directly. However, if you contact us at, we can send you a claim form that can be filled and mailed to your insurance provider along with your OTIS reciept. Just in case, contact your dental insurance providers to confirm coverage and reimbursement.

Do I have to wear my OTIS Night Guard every night?

You may not know this, but our teeth are always shifting, especially while we’re asleep. This is why it’s important to wear your night guard every night. Even if there are nights when you think it's not needed, wearing your night guard for just 30 minutes can help ensure it fits comfortably in your mouth when needed.

How do I take care of my OTIS product?

Always brush and floss before wearing your OTIS products. After use, rinse with warm water and let it air dry in the case. You can also clean your OTIS product with mild, unscented soap and warm water.


  • Do not use mouth rinse, toothpaste, or denture cleaner to clean your OTIS product.
  • Do not soak in hot water. Doing so may distort the fit of your OTIS product.

How long does the OTIS Night Guard last?

Everyone's bruxing habits are different, which is why night guards can last anywhere between 6 months to 5+years. If your OTIS Night Guard is prematurely cracked and/or damaged from “brux” wear within the 60-day warranty period, please contact us and we'll replace it free of charge. In order to receive a free replacement, the damaged product must be returned for inspection.

What if the night guard doesn’t fit properly?

This rarely happens... but if it does, email us at and we’ll figure out what happened and how to correct it.

What is your return policy?

Adjusting to your night guard may take 2-3 nights. But if you’re still unhappy, we offer a 60-day guarantee (minus lab fees).


What is Tooth Whitening?

Tooth whitening is the removal of stains and discolorations from the enamel and dentin. The outer layer of the tooth is enamel, and beneath the enamel is dentin. Enamel is thin and typically much lighter in color, while dentin is darker in color and makes up the bulk of the tooth. Enamel can be discolored over time simply from age, but also from outside sources like coffee, tea, tobacco, and other foods and beverages. Also, as we age, our enamel thins, causing more dentin to show through, making the overall appearance of the tooth look darker. Whitening your teeth removes these stains and discolorations, giving you a whiter, brighter smile.

How does teeth whitening work?

Working from the inside out, the active ingredients in Opalescence gels penetrate your teeth to break down the discolored molecules deep down in your teeth, removing stains and whitening your smile. Our original, patented formula contains PF (potassium nitrate and fluoride) and is sticky and viscous, so it stays where it’s placed. This unique feature prevents the gel from migrating during treatment and helping keep the gel and custom tray in place so it can continue whitening your teeth for the duration of the treatment

Will I need a blue light to help whiten my teeth?

There's a trend with some whitening treatments using a blue light during the whitening process. You've probably seen commercials for these kinds of teeth whiteners, or maybe you've even seen kiosks in the mall where they'll use a blue light to whiten your teeth. Are these lights really effective though?

The answer is NO. Current research shows that Hydrogen Peroxide and Carbamide Peroxide (found in any whitening gel) are effective in whitening teeth, and that light activation adds no additional benefit. Basically, it's just a marketing gimic... it's just a light.

Am I a candidate for tooth whitening?

Teeth whitening is a safe, comfortable way to get a bright, white smile. Results and treatment time may vary depending on the level of staining and whiteness desired. Crowns, bridges, fillings, and veneers will not whiten.

WARNING: Pregnant women, those with gum disease, severe bruxism, worn enamel, cavities, and exposed roots should not whiten their teeth.

Will the whitening cause tooth sensitivity?

Tooth sensitivity is a relatively common side effect of any teeth whitening system. Fortunately, we offer Opalescence whitening gels, which contain Potassium Nitrate and Fluoride. This helps strengthen teeth and minimize post-whitening sensitivity. When in doubt, consult your dentist who may recommend an over-the-counter anti-sensitivity toothpaste, as well.

How long will it take to see results?

Everyone responds differently to whitening treatments and everyone will whiten at different rates. Some stains are easier to treat than others. Teeth that are yellow or brown are easier to whiten than teeth that are gray/blue. Younger patients typically whiten more quickly than older patients, but every patient is different.

When whitening, keep in mind that your smile looks most natural when the color of your teeth matches the whites of your eyes. Some people want a Hollywood white smile, but that is not a natural color for teeth and few people can actually reach that color of white.

How long will the results last?

Teeth whitening results are very stable, leaving you with a stunning smile long after treatment is over. However, there are a few factors that can make teeth lose their luster: genetics, diet, age, some medications (like tetracycline), and certain habits (like smoking) may affect the length of your whitening results. Fortunately, you can purchase more whitening gels—individually (3-4 applications) or 4-pack—and keep your smile brilliant and beautiful!

Can I whiten dental restorations, like fillings and/or crowns?

No, only natural tooth structure can be whitened; any crowns or fillings that you have will not react to whitening products.

How can I get more whitening gel?

Opalescence Whitening Gels can only be purchased by existing customers who have OTIS custom whitening trays. Please contact us for refills.
