Is Teeth Whitening Safe?

Safe Teeth Whitening In Dental Office

There's been a major boom in cosmetic dentistry in recent years with professional teeth whitening trending in the spotlight. Whether the result of high-definition televisions or virtual conference calls, there has been an uptick in consumers looking to improve their smiles. In fact, over 37 million Americans used teeth whitening products in 2020 alone. But in a market inundated with various brands and messages, it has left many wondering, “Is teeth whitening safe?”.

We’re happy to respond with a resounding YES! Teeth whitening technology has significantly improved over the last decade, leading to safe teeth whitening methods readily available for consumers. 

Is Teeth Whitening Safe During Pregnancy? 

Teeth whitening may not be dangerous during pregnancy, but products containing peroxides are not recommended for pregnant women, which is why it’s best to avoid professional whitening treatments during those nine months. The percentages of chemicals used in teeth whitening procedures are higher than we normally come into contact with, and safety is the number one priority for both mother and child. We do encourage these patients to keep their gums healthy by brushing and flossing along with regular dental checkups. 

Is it Safe to Whiten When Breastfeeding? 

Since teeth whitening is not endorsed during pregnancy, many women wonder if it’s safe to whiten their teeth post-delivery. Clinicians have mixed opinions, but we recommend mothers who are breastfeeding wait to whiten their teeth until they are no longer doing so. The small amount of hydrogen peroxide swallowed during a whitening treatment may or may not be enough to enter the bloodstream, so better to be cautious. 

Today’s teeth whitening methods have drastically improved results both in-office and at home. Those looking to whiten teeth can feel confident in achieving enhanced smiles without discomfort or side effects. What’s most important is that dental professionals take the time to educate and inform patients on safe, reliable whitening brands. Doing so will ensure the best results, leading to happier patients and healthier smiles.

Why Choosing the Right Whitening Technology Matters

In a market inundated with various claims about teeth whitening efficacy, and a slew of devices all promising beautiful, bright smiles, the technology you choose to integrate into your office matters. All whitening systems are not created equal, so it’s crucial to select products backed by research. 

The right professional whitening technology will also support patient compliance and set you apart from competitors. Whitening patients often make the best patients, taking better care of their teeth and pursuing more elective dental procedures. Selecting the right whitening technology makes your practice a destination for anyone looking to improve their smile. 

Is GLO Teeth Whitening Safe?

Perhaps the primary factor in determining the safety of a whitening device relies on the quality of the product. Whether patients opt to whiten in-office or at home, GLO Professional Teeth Whitening features innovative and award-winning patented technology. The gentle warming heat and safe LED light creates a safe, protective barrier between the whitening gel and gums, eliminating discomfort for those with even the most sensitive teeth. Our products are also FDA-registered, vegan, gluten and latex-free, plus made in the USA!

Is the GLO Accelerator Safe? 

The GLO Professional Whitening Accelerator features patented GLO illuminated heat technology. The mouthpiece warms immediately and maintains the optimal temperature during the whitening process. This accelerated whitening keeps wearing times short (only 8 minutes) with less chance of sensitivity. Our products are free of UV light, making them a safe choice for both in-office and at-home whitening.  

Is Blue Light Teeth Whitening Safe? 

Light-activated teeth whitening products can be found at most major retailers nationwide, and with a variety of options, it’s essential consumers understand how they work and what is safe. 

Blue light, the most common type of LED lighting, activates hydrogen peroxide or carbamide peroxide, which are two primary whitening ingredients. In turn, this speeds up the whitening process as the chemical reaction gently lifts stains off teeth. As long as the whitening device is temperature-controlled, they are completely safe. The GLO mouthpiece is controlled so as not to exceed this optimal, warm temperature.

Is LED Teeth Whitening Safe? 

Similar to blue light teeth whitening, LED lights are another safe and effective whitening option. They work by initiating a chemical reaction between the warming heat and whitening gel, removing surface stains from the enamel and leading to brighter, whiter smiles. An LED light will not change the color of the teeth if used alone but acts as a catalyst to speed up the whitening process. 

Is UV Teeth Whitening Safe? 

Ultraviolet light is not endorsed by the American Dental Association or recommended like blue and LED light options. UV light has been shown to produce levels of radiation leading to cell mutations, especially when used without the guidance of a licensed dental professional. Gum tissue is extremely sensitive and vulnerable to damage caused by intense heat and light. We suggest opting for blue light or LED teeth whitening products as an alternative.

Is Teeth Whitening Safe at the Dentist? 

For patients looking for the safest way to whiten teeth, having it done at their dentist’s office is the best bet. When scheduled in-office, clinicians can check for any pre-existing conditions that may be affected by teeth whitening and can also carefully monitor for any reactions or adverse effects. But rest assured, today’s teeth whitening technology has changed the industry and can deliver impressive results without side effects. While the initial investment is more than over-the-counter methods, results are faster and last longer. 

Is Hydrogen Peroxide Safe For Teeth Whitening? 

“Hydrogen products are the most widely used and preferred method of teeth whitening. They’re backed by the ADA for their safe and effective use, with no increased risk to a tooth’s enamel or gum tissue. Hydrogen peroxide is the main ingredient in most tooth-whitening products,” says Dr. Kami Hoss, dentist and author of If Your Mouth Could Talk. “Products containing peroxides, such as hydrogen peroxide and carbamide peroxide, act as bleaching agents to change the color of teeth. Peroxide can partially penetrate the layers of teeth, removing compounds that cause discoloration.” (Source, Forbes)

The key to safety is knowing the proper amount to use on teeth to avoid damage. That’s why products with a high concentration of hydrogen peroxide should only be used under the supervision of dental professionals. 

Is Hydrogen Peroxide Safe For Your Mouth? 

Hydrogen peroxide has been a longstanding household staple, known for its disinfectant, antiviral, and antibacterial properties. But can something that cleans your countertops also clean your mouth? It turns out yes, hydrogen peroxide is that good. 

Dentists recommend diluting hydrogen peroxide with water to obtain a 1% dilution. While not recommended for daily use, it’s perfectly safe to rinse your mouth with this mixture several times a month to fight germs and combat gingivitis. Patients should not use it to cure sore throats or inflamed gums as this could lead to further damage, and the rinse should never be swallowed.

Is Teeth Whitening Safe For Enamel? 

While enamel may be the strongest tissue in the human body, it doesn’t mean it’s not susceptible to damage. Enamel and dentin, the main portions of the tooth responsible for color, are what react to the teeth whitening solution. Stains are gently lifted when they make contact with hydrogen peroxide.  

Before beginning a tooth whitening regime, some wonder if it will do more damage than good. Thankfully, with today’s advances in efficacy, this isn’t the case, and patients should feel confident their enamel will be protected when using whitening products.

Is Teeth Whitening Safe to Swallow? 

As with any other chemicals, teeth whitening agents must be used responsibly. It is perfectly safe to swallow a small amount while whitening your teeth, and we tell our GLO Pro patients they can swallow as they normally would when using the GLO mouthpiece. However, products should not be used or consumed beyond their intended use and must be kept out of reach of children.
