You can’t put a price on the benefits of a bright, beautiful smile. However, teeth come in many shades and tones, and they change color over time. Teeth whitening is a popular solution to combat stains and discoloration. You may think of teeth whitening as a relatively new treatment, but people have sought a dazzling smile for thousands of years. Thankfully, you don’t have to use urine to treat stains anymore. Here’s how teeth whitening has changed throughout time.
Early Teeth Whitening Methods
The Ancient Egyptians took pride in their appearance. Besides wearing makeup to enhance their looks, the color of their teeth often reflected their wealth. They would use a frayed end of a stick to brush ground pumice and white vinegar on their teeth.
The Ancient Romans took a different approach to keep their smiles bright. They turned to human urine because of its ammonia contents. Ammonia acts like bleach because it is acidic. Although it can combat stains, it also destroys enamel.
Dentists looked quite different in the 18th century. You didn’t just visit the barber for a haircut. They also treated dental problems. They would use metal files and a strong nitric acid to reverse stains.
Modern Teeth Whitening
Early teeth whitening techniques were often abrasive or acidic, which caused irreversible enamel loss. In the 19th century, teeth whitening took a major turn with the discovery of hydrogen peroxide. When exposed to a special heating lamp, it accelerated the whitening process.
Hydrogen peroxide was the common solution for tooth stains until 1989 when carbamide peroxide became the go-to ingredient. Now, your teeth can get up to 8 shades whiter using an in-office or take-home kit. Modern whitening systems are formulated to resolve stains without damaging your enamel to prevent tooth sensitivity.
Your results can last for many months or years with the right aftercare, like brushing and flossing. Avoid stain-causing foods and drinks to prevent new discoloration. Visit your dentist every 6 months for a cleaning and checkup. They can also provide you with a touchup kit to keep your pearly whites their brightest.
