“Being a longtime coffee and tea drinker, I have long struggled with the impact on my teeth and overall oral health. Over time, I noticed an unsightly build-up of tartar on my teeth, which seemed resistant to regular brushing and flossing. Seeking a remedy, I decided to give 𝐎𝐲𝐢𝐤𝐞𝐲™ 𝐍𝐢𝐚𝐜𝐢𝐧𝐚𝐦𝐢𝐝𝐞 𝐈𝐧𝐭𝐞𝐧𝐬𝐢𝐯𝐞 𝐎𝐯𝐞𝐫𝐧𝐢𝐠𝐡𝐭 𝐓𝐞𝐞𝐭𝐡 𝐖𝐡𝐢𝐭𝐞𝐧𝐢𝐧𝐠 𝐏𝐞𝐧 a try, and it proved to be a great solution. The combination of Niacinamide and natural whitening agents in this pen has worked wonders in restoring the brilliance of my smile and tackling the stubborn tartar issue. With regular use, I have noticed a remarkable improvement in both the whiteness of my teeth and the overall freshness of my breath. I'm thrilled that I found this pen, as it has truly helped me regain my confidence in my oral health and has become an indispensable part of my daily routine.”

“As someone who enjoys occasional cigars, dips, and regular coffee consumption, my teeth had become heavily stained over time. Despite trying numerous teeth whitening products, none seemed to deliver the desired results until I gave 𝐎𝐲𝐢𝐤𝐞𝐲™ 𝐍𝐢𝐚𝐜𝐢𝐧𝐚𝐦𝐢𝐝𝐞 𝐈𝐧𝐭𝐞𝐧𝐬𝐢𝐯𝐞 𝐎𝐯𝐞𝐫𝐧𝐢𝐠𝐡𝐭 𝐓𝐞𝐞𝐭𝐡 𝐖𝐡𝐢𝐭𝐞𝐧𝐢𝐧𝐠 𝐏𝐞𝐧 a chance. To my delight, consistent use of this pen yielded amazing results. Not only did it effectively whiten my teeth, but I continue to see ongoing benefits from using it twice a day. This pen has provided a reliable solution to stubborn stains that other products couldn't match.”- Roger Hargett

"My teeth and gums got worse as I got older because I didn’t take proper care of them. This made eating and talking difficult until my friend recommended the 𝐎𝐲𝐢𝐤𝐞𝐲™ 𝐍𝐢𝐚𝐜𝐢𝐧𝐚𝐦𝐢𝐝𝐞 𝐈𝐧𝐭𝐞𝐧𝐬𝐢𝐯𝐞 𝐎𝐯𝐞𝐫𝐧𝐢𝐠𝐡𝐭 𝐓𝐞𝐞𝐭𝐡 𝐖𝐡𝐢𝐭𝐞𝐧𝐢𝐧𝐠 𝐏𝐞𝐧. I use it every night, and I’ve seen amazing results after just a few weeks of use. My teeth are visibly whiter, and my gums look much healthier! My confidence is back in no time! Thank you so much!"

Alarming Oral Health Statistics:

⚠️Approximately 3.5 billion people are estimated to be affected by oral diseases.

⚠️Tooth decay and tooth loss, left untreated, is the most prevalent health issue as per the Global Burden of Disease 2019 report.

⚠️Treating oral health conditions is expensive and typically not covered by universal health coverage (UHC) policies.

⚠️Most low- and middle-income countries lack adequate services to prevent and treat oral health conditions.

⚠️Severe oral problems can lead to a 2 times increased risk of cardiovascular disease, respiratory infections and various complications.

Discover 𝐎𝐲𝐢𝐤𝐞𝐲™ 𝐍𝐢𝐚𝐜𝐢𝐧𝐚𝐦𝐢𝐝𝐞 𝐈𝐧𝐭𝐞𝐧𝐬𝐢𝐯𝐞 𝐎𝐯𝐞𝐫𝐧𝐢𝐠𝐡𝐭 𝐓𝐞𝐞𝐭𝐡 𝐖𝐡𝐢𝐭𝐞𝐧𝐢𝐧𝐠 𝐏𝐞𝐧, a natural and effective way to brighten your smile while you sleep. Its powerful Niacinamide formula helps remove stains, strengthen enamel, and promote a healthier mouth. Simply apply before bed, and wake up to whiter, fresher teeth.

Daily food residues in the mouth create an environment for diverse bacteria and microorganisms to thrive between teeth and inside the oral cavity. Consequently, this can result in a range of oral health problems, such as bad breath, mouth ulcers, yellow teeth, cavities, tartar buildup, inflamed and bleeding gums, tooth sensitivity, weakened or missing teeth, swollen gums, toothaches, loose teeth, tooth loss, and in severe cases, oral cancer.

Gum disease is a chronic inflammatory disease that develops gradually. First, the formation of plaque causes discoloration of the teeth and bad breath. The toxins produced by the bacteria in plaque cause the gums to become red, swollen, and bleed. Without proper treatment, it can develop into periodontitis, causing bone resorption, tooth loss, and potentially oral cancer.

Proper oral care is crucial in preventing and addressing these potential issues and maintaining optimal oral health.

🔥Niacinamide (Vitamin B3): a form of Vitamin B3, plays a key role in whitening your teeth by inhibiting the production of melanin, the pigment responsible for tooth discoloration. Its anti-inflammatory properties also help to control gum inflammation, reducing irritation and promoting overall gum health.

🔥Hydroxyapatite: A naturally occurring mineral in your teeth, Hydroxyapatite helps to remineralize and restore tooth enamel, enhancing tooth strength and brightness. It fills in microscopic cracks and abrasions, making your teeth smoother and shinier, while also protecting them from further staining and damage.

🔥Coenzyme Q10: Known for its powerful antioxidant properties, Coenzyme Q10 helps to support oral health by neutralizing free radicals and reducing oxidative stress in the mouth. It promotes healthy gum tissue by improving circulation, which can help prevent gum recession and inflammation.

🔥Activated charcoal: a natural ingredient that works as a mild abrasive to help remove surface stains and plaque. It absorbs toxins, bacteria, and other harmful substances from the mouth, leaving your teeth visibly whiter and your mouth feeling fresh.

🔥Vitamin C: essential for healthy gums and teeth. It aids in collagen production, which is crucial for maintaining the integrity of gum tissue. Additionally, its antioxidant properties support oral health by combating inflammation and protecting against bacterial growth.

"I have been smoking for almost twenty years, which caused my teeth to become very yellow. My gums were constantly bleeding and swollen, and my teeth even started to loosen, which really scared me. I tried many different treatments and spent a lot of money, but nothing worked.
