Teeth whitening has become a sought-after goal for many, but due to the high cost of in-office treatments, cheaper and more accessible alternatives are being sought, such as over-the-counter at-home teeth whitening kits. However, these products can pose significant health risks, as dentists warn that some contain high levels of bleaching agents that can damage gums and enamel.
Coffee is a major cause of tooth discoloration, but the type of coffee bean can affect the extent of the discoloration. According to a study published in the American Journal of Dentistry, coffee made from Robusta beans is less likely to stain teeth than coffee made from Arabica beans.
This is because Robusta tablets are less acidic, which reduces the effect of acidity on tooth enamel.
Experts recommend rinsing your mouth with water after drinking coffee to maintain healthy teeth.
Research has shown that iced coffee is less likely to stain teeth than hot coffee. Adding milk to coffee can also reduce its acidity and therefore its effect on tooth enamel.
Pineapple is considered beneficial for teeth whitening thanks to its bromelain enzyme, which helps break down surface stains. However, caution should be exercised due to the high acidity of pineapple, which can weaken enamel; therefore, rinsing with water after consuming it is recommended.
Despite its benefits in enhancing flavor, soy sauce can harm your teeth. Studies have shown that soy sauce contains pigments that contribute to tooth discoloration and make teeth more susceptible to brown stains.
It is also advisable to avoid consuming excessive amounts of tomato sauce.
Electric toothbrushes, especially those with sonic technology, are among the best options for combating tooth discoloration. These brushes emit sonic waves to rapidly move the bristles, helping to remove plaque and reduce stains.
If you wear dental prosthetics such as crowns or veneers, you should be careful when using whitening products, as they can cause a color difference between your natural and artificial teeth. Whitening agents cannot penetrate crowns or fillings, making your natural teeth appear whiter while the prosthetic teeth remain the same color.
Antibacterial mouthwashes like Corsodyl may be helpful in treating gum disease, but overuse can lead to tooth discoloration due to the chlorhexidine digluconate they contain. Experts therefore recommend using mouthwashes containing this ingredient for short periods, especially if you drink beverages like coffee or tea.
