Colgate Optic White Pen at a Glance


Colgate is a giant in the at-home dental care industry. Founded way back in 1806, they’re one of the oldest dental health and wellness companies in the world. They have state-of-the-art labs and product development facilities, allowing them to craft truly innovative products like their Optic White Overnight Teeth Whitening Pen.

In general, whitening pens are less effective than strips and trays because there is nothing to hold the whitening solution to the teeth; it gets washed away by your saliva within minutes. Colgate’s Overnight Whitening Pen uses a special solution that hardens into a removable varnish within one minute. This keeps it in place until you brush it away in the morning.

Colgate’s Optic White Overnight Teeth Whitening Pen is widely available. You can purchase it online or at most pharmacies and big box stores. As a bonus, it’s backed by a 30-day money-back guarantee, so you can “test drive” it without fear.

Pros & Cons


Colgate Optic White Overnight Teeth Whitening Pen is an excellent product, and if you purchase it, you’ll likely love your results. But like any whitening product, it isn’t perfect. Here are its most notable advantages and disadvantages.

Pros

  • The gel hardens into a varnish-like film to keep it in place overnight.
  • Application is easy and intuitive.
  • If you aren’t satisfied, you can request your money back within 30 days of purchase.
  • The company claims it can remove up to 15 years of stains.

Cons

  • It only has a 3% peroxide solution.
  • Quite a few customers have complained that their gel solution was dried out when they purchased the pen.

Should You Buy Colgate Overnight Teeth Whitening Pen?

Colgate’s Teeth Whitening Pen blends the reliability of an established brand with the convenience of overnight whitening and widespread availability. If those are your priorities, it’s a great option.

Effectiveness


A whitening pen can have all the perks in the world, but if it doesn’t whiten your smile, it isn’t worth your money. So, is Colgate Optic White Overnight Teeth Whitening Pen effective?

Let’s start by establishing a baseline: whitening pens are not as effective as strips and trays at whitening your teeth. This is a universal truth — at least for now. They’re more effective than whitening toothpaste, but not quite on the level of whitening strips.

Colgate Optic White Overnight Teeth Whitening Pen can brighten your smile by two shades over a standard 14-day course of treatment. It uses a 3% hydrogen peroxide concentration, which is standard for whitening pens, but weaker than you would find in strips and tray kits. Compared to your typical whitening toothpaste, this pen delivers about 15 times the whitening power.

Compared to most other pens, the Colgate Optic White Overnight Teeth Whitening Pen is more effective due to the way the gel hardens on the teeth. Within a minute of application, the gel turns into a varnish-like film that remains on your teeth even when it comes into contact with your saliva. As a result, it whitens your teeth throughout the night.

Colgate notes that their pen will not work on all types of stains. The deeper your stains are within your enamel, the less likely it will work. It’s also more effective on yellow stains than brown ones. If you don’t see the results you want at first, though, you can continue for up to three weeks before you need to give your teeth a break.

Affordability


Some budgets are bigger than others, but in the end, we all have one. When purchasing a teeth whitening product, you want to be certain that it offers the right price — and value — for you. Overall, whitening pens don’t offer the same effectiveness as other products, but they make up for it with their affordability.

The Colgate Optic White Overnight Teeth Whitening Pen is one of the most affordable whitening pens we reviewed. Each pen costs $25, and you get 35 treatments out of it.

Despite its low price, there are ways to make the cost of the Colgate Optic White Overnight Teeth Whitening Pen even more approachable. If you’re interested in making whitening an ongoing part of your routine, you could opt in to Colgate’s subscribe and save option, which takes 5% off the price and sends you a new pen at a frequency of your choosing.

You can also finance your purchase through AfterPay. This allows you to break your total into four interest-free installments instead of paying all in one go. The only catch is that financing is only available for purchases of $35 or more, so you’d need to buy at least two pens to qualify. But if you decide this pen is the right match for you, it couldn’t hurt to buy a few at once.

On top of that, Colgate’s Optic White Overnight Teeth Whitening Pen is backed by a 30-day money-back guarantee, which is pretty rare with teeth whitening pens. If you are looking to dip your toe into the water, this is a pretty safe option.

Quality of Ingredients


The first thing you want to know about a whitening pen is if it works. But you also need to know exactly how it works. This comes down to the ingredients.

Every whitening product has an active ingredient that breaks up and lifts out stains. Colgate’s Optic White Overnight Teeth Whitening Pen uses hydrogen peroxide. At just a 3% concentration, it’s not very powerful, but since you keep it on your teeth overnight, this helps prevent sensitivity.

In addition to hydrogen peroxide, Colgate Optic White Overnight Teeth Whitening Pen also has three inactive ingredients:

  • Alcohol Solvent: Helps combine the other ingredients into a solid solution
  • Acrylates/Octylacrylamide Copolymer: Turns the gel into a film once applied to the teeth.
  • Water: Keeps the gel in liquid form until it comes into contact with air.

While the formula is not all-natural, it is sugar-free, gluten-free, and vegan, so it’s a viable option for most people.

Convenience


Pens are perhaps the most convenient teeth whitening method. There’s no strip to remove, no gel to measure from a syringe, and no trays to wear and clean. Overall, the convenience of Colgate’s Optic White Overnight Teeth Whitening Pen is about equal with other pens.

You start by brushing, flossing, and drying your teeth. Then, you’ll take off the cap and twist the end of the pen until you see gel emerge from the tip. On the first use, this can take quite a few twists — sometimes as many as 30! But it’s much less on subsequent applications.

Before you apply the gel, verify that your teeth are still dry. If not, dry them again and keep your mouth open. Use cotton balls to keep your lips off your teeth if necessary. Start the application at the gumline of each tooth and brush downward, evenly distributing the gel across the teeth. Remember that, unlike with other whitening products, you should only use pens on the front teeth, not those that touch your cheeks when you smile.

Keep your lips off of your teeth for about 60 seconds after you finish applying the gel. This allows it to turn into a film that stays on your teeth throughout the night. In the morning, you just brush it off and go about your usual routine.

Overall, this is pretty convenient, but there is one aspect that might be a turn-off: you have to brush your teeth first thing when you wake up. So, if you start your day with coffee, you might want to delay it until that toothpaste taste fades.

Comfort


Teeth whitening is rarely a totally comfortable process, but whitening pens get pretty close. Since you are just painting gel onto your teeth, you can skip the awkwardness of trays and strips.

The Colgate Optic White Overnight Teeth Whitening Pen might be the least comfortable option we’ve reviewed due to the film it creates on your teeth and the taste. With most whitening pens, the gel is a bit goopy on your teeth for a few minutes, but then it gets washed away by your saliva. The Overnight Teeth Whitening Pen leaves a film in your mouth all night. That’s not a problem if you sleep well. But if you toss and turn, it might be bothersome.

For most people, flavor is the bigger issue. Once the gel hardens, it’s less noticeable, but the flavor of peroxide is powerful. And unlike many other products, Colgate doesn’t include any flavoring agents to improve the taste.

It’s not all negatives, though. The formula is designed to be gentle on the teeth, making it less likely to cause sensitivity. According to Colgate, it uses slow-release technology. While we aren’t sure how this is the case with the four ingredients in the formula, it does seem that most customers find it is pretty gentle on their teeth.

What Are Customers Saying?


Overall, Colgate Optic White Overnight Teeth Whitening Pen customers are happy with their experience. Those who have used other whitening pens in the past are particularly big fans of the ability to wear it all night, allowing the peroxide to really work before it is brushed off.

People also really love the stand that comes with the pen. While the design isn’t necessarily display-worthy, it does make organization easier and helps you remember to use the pen each night.

The main complaint we found was related to defective products. Numerous people who ordered online reported receiving pens with dried-out gel, making it impossible to use. That’s frustrating, but the company offers a full refund or replacement when this occurs.

Final Thoughts


The Colgate Optic White Overnight Teeth Whitening Pen is an affordable option that offers a twist on the typical whitening pen — the gel works on brightening your smile all night! It’s easy to use, easy to store, and delivers better results than most of its competitors. If you don’t mind the texture and flavor, it could become your go-to whitening product.

But it isn’t the only great whitening pen on the market. Check out our review of the 5 best whitening pens to see if another product might be a better fit for you.

Frequently Asked Questions

What are the primary advantages of using whitening pens over strips and trays?

We think the main benefits of choosing whitening pens are:

  • They make it easy to prevent chemical burns on the gums.
  • They’re highly portable.
  • You don’t need to carefully measure the gel, just twist until you see some on the brush.
  • If you only want to whiten certain teeth, you can specifically target them.

Are there any tricks for keeping my lips off the teeth while the gel dries?

You can tuck cotton balls between your lips and gums. This helps stop saliva from reaching the gel.

Can it really be safe to whiten your teeth at home?

Yes! At-home whitening isn’t new. Millions of people do it every year. Just take the following precautions:

  • Purchase authentic products, not knock-offs.
  • Follow the directions included with your pen.
  • Make sure you aren’t allergic to the ingredients.

Are whitening pens for full whitening or just touch-ups?

Most whitening pens are intended for maintaining a whiter smile after using a stronger kit or getting professional whitening. The exception is SNOW, which is a full whitening system.

My teeth used to be sparkling white. What happened?

Everyone is susceptible to teeth discoloration, though some are more at risk than others. The number-one culprit behind yellowing teeth is bad habits — like smoking and drinking dark beverages like coffee or red wine. However, genetics also play a role. Those with stronger enamel are less likely to see their teeth yellow as they age.

Can I use a whitening pen if I have braces?

It’s unlikely to cause damage but it isn’t a good idea. The pens will only whiten the exposed surface of your teeth, leaving the portion below your brackets stained. When your braces come off, they’ll leave behind stains in the shape of your brackets.

Is it OK to use whitening pens when pregnant or breastfeeding?

Due to limited research, there isn’t a definitive answer to this. Talk to your OBGYN or pediatrician and follow their guidance.

Can whitening pens get rid of stains on cosmetic and restorative dentistry?

It depends. Some products are safe to use on veneers, caps, and crowns; others are not. When they are safe, they can eliminate surface stains.

Is it dangerous to use a whitening pen more often than indicated on the instructions?

It can be. Since peroxide opens the pores in the enamel, using a product too often could damage your teeth.

    My mouth gets dry during the night…I usually find the need to take a sip of water…..will that ruin or wash away the effect of the gel coating?
