What causes teeth to become yellow?

Teeth can become yellow due to a combination of factors. The outer layer of teeth, called enamel, can thin over time, revealing the naturally yellowish dentin beneath. Staining substances from food, and drinks like coffee and red wine, tobacco use, and inadequate oral hygiene can also contribute to discoloration. Additionally, aging, genetics, and certain medical conditions can play a role in the yellowing of teeth.
How does the Fivfivgo™ Medical-Grade Teeth Whitening Serum Pen work?
Fivfivgo™ Medical-Grade Teeth Whitening Serum Pen works by breaking down stains on the enamel and dentin surfaces of the teeth. When applied to the teeth using the pen’s applicator, the gel seeps into the microscopic pores of the enamel, where it releases oxygen molecules. These oxygen molecules penetrate the enamel and dentin, effectively breaking apart the chemical bonds that hold the stain molecules together. As a result, the stains become less concentrated and appear lighter, leading to teeth that appear whiter. It’s important to follow the instructions provided with the pen to ensure safe and effective use, as excessive or improper use can lead to tooth sensitivity or damage.
Consists of 4 active ingredients for Medical-Grade Teeth Whitening Serum Pen

Propolis – can be beneficial for teeth due to its antimicrobial and anti-inflammatory properties. It has been used in oral care products like toothpaste and mouthwash to help fight against bacteria that cause tooth decay and gum disease. Propolis may also promote healing and reduce inflammation in the gums, contributing to overall oral health.

Chamomile – It may help soothe gum irritation and reduce inflammation in the mouth. Additionally, chamomile’s antibacterial qualities might contribute to maintaining oral hygiene and preventing certain oral infections.

Galla Japonica – also known as Chinese gall, contains compounds like tannins that possess astringent properties. These compounds can potentially benefit oral health by helping to control bacterial growth and reducing plaque formation on teeth. Galla Japonica’s astringent nature might also contribute to strengthening gums and preventing certain types of oral infections.

Sodium Bicarbonate – can help whiten teeth due to its mild abrasive properties and ability to remove surface stains. When used as a toothpaste or in combination with toothpaste, it can gently scrub away stains caused by coffee, tea, or other pigmented foods.
