Chewing gums — These contain peroxide-based whitening ingredients and work to remove surface stains while freshening your breath
On the other hand, hydrogen peroxide breaks down faster than carbamide peroxide and lightens stains in as little as 30 to 60 minutes. But it doesn’t produce much effect until the next application. 2 APPLY: Apply a thin layer to each tooth and allow to dry. 1-2 drops of serum covers up to 4 teeth. Wait 1 hour, then brush with water to remove. Authority to prescribe an Authority medicine is granted for specific indications and/or for certain patient circumstances. Authority may be obtained by telephone to Medicare Australia (known as "phone approval") or in writing from an authorised delegate of the Minister for Health. Teeth whitening pens work the same way as other whitening products, but they use a serum to apply whitening ingredients to your teeth. Most teeth whitening pens use a peroxide formulation—either hydrogen or carbamide—to break down stains. “Peroxide gels break down into water, oxygen, and reactive oxygen molecules,” explains Dr. Velayo. “These reactive oxygen molecules treat both the enamel and the dentin, oxidizing the bonds of discolored stain molecules. By changing the stained molecules, the tooth becomes lighter.”Most effective over-the-counter (OTC) teeth whitening products contain hydrogen or carbamide peroxide. These are peroxide-based bleaches that act directly on teeth stains. To help you narrow down the list of whitening kits that will meet your needs, we tested the best options on the market. We tried out dozens of whitening kits, following each brand's specific instructions. Throughout the test, we paid close attention to how easy it was to use the product, whether we experienced any discomfort or teeth sensitivity, and how effective the product was in whitening our teeth. We then took careful notes on the appearance of our teeth before, during, and after the whitening process.An orthodontist from our Medical Expert Board reviewed the contents of this article for medical accuracy surrounding dental hygiene and the efficacy of active whitening ingredients.
A clinical evaluation of carbamide peroxide and hydrogen peroxide whitening agents during daytime use . ” PubMed. Teeth whitening pens come in various strengths and with peroxide-free formulations so that most people can use them. While their lower peroxide percentages may not get you the drastic results you want, this makes them safer to use, as Dr. Yazdani explains that “because they usually have a lower concentration of the bleaching agent, there is little risk for enamel damage.” Teeth whitening pens containing hydrogen or carbamide peroxide are proven to be safe and effective. While bleaching can cause tooth sensitivity, it is unlikely to happen with a whitening pen if you follow the recommended use. 4 How Effective are Teeth Whitening Pens? Colgate Optic White Pro Series Express Teeth Whitening Treatment Pen, gives you whiter teeth in just 1 day*.Crest Whitening Emulsions Leave-on Teeth Whitening Gel Kit: This was easy to apply with a pleasant, mild taste, but in testing, we saw zero whitening effects—even with the maximum amount of allowed applications per day. Applicator: Teeth whitening pens typically have small brushes at the tip, similar to many lip glosses and under-eye concealers you'll see on the market—this is ideal because the thin, flexible brush tip allows you to apply the product in the crevices of your teeth. Pens that feature silicone applicators don’t provide the same precision, which can prevent you from evenly coating your teeth. In testing, this gel was easy to put on and caused no discomfort during or after application (including for those of us with sensitive teeth). The mouthpiece fit well and stayed in place, thanks to the fact that it’s soft and flexible, not rigid. We also loved that the tray could be plugged into our smartphones, so we could get up and move around the house while we waited out the whitening time. You shouldn’t head into a whitening toothpaste expecting the same results as whitening strips or a kit with gels and trays. But a whitening toothpaste like this one from Opalescence can help whiten teeth or help maintain a whiter smile over time. We rated it high for convenience and comfort, mostly because it functioned like normal toothpaste. We liked that there was no learning curve to the application process; it was easy to work into our daily routine, and it didn’t cause any initial discomfort.
To choose the best teeth whitening pens, we researched the top options, including a few we tested in our lab tests. We considered each pen for its ingredients, wear time, number of applications, and time to results for touch-ups and full whitening treatments. Initially, we couldn’t leave the tray in for the recommended 15 minutes because it was so uncomfortable. But over time, we did get used to it. The best part was that our teeth whitened. Even though we only left it in for about eight minutes, our teeth went up a full shade. It hurt, but the pain was worth it in our eyes. We also started with the highest concentration possible, which we wouldn’t recommend if you have sensitive teeth or have never whitened your teeth before (in that case, you may want to start with the lowest concentration and work your way up from there).We used the products for the first time in our Verywell Testing Laband continued to use them at home according to manufacturer instructions. In the Lab and at home, we took note of how easy it was to set up and apply the product or treatment, as well as how our teeth felt before and after the treatment (e.g., if there was any sensitivity or discomfort from the appliance or device itself). Sodium fluoride and sodium hexametaphosphate create a barrier on your enamel. The barrier prevents mineral loss, strengthening teeth structures and a whiter appearance. Price As for the results it delivers, these also impressed us. We saw a noticeable improvement in the whiteness of teeth—about four shades—after using it twice daily as directed for just one week. The one downside is that it can cause minor sensitivity if you get the gel on your gums, but this is typical for whitening products, and if you’re careful while applying it with the brush, this shouldn’t be a big issue for you. In the UK, teeth whitening kits can be bought over the counter but only if they contain less than 0.1% hydrogen peroxide. This means they aren't as strong as professional whitening treatments, as a qualified dentist can legally use up to 6% hydrogen peroxide. When looking at whitening pen-LED combos, we also considered another option. The Go Smile Glo On the Go—a fan-favorite on TikTok—uses a similar process with less effective results.
