Yellow teeth are caused by factors, such as smoking, certain medical conditions, foods that are high in tannins, poor oral health, and excessive
fluoride exposure. A white smile will make you look young and more attractive. It will also improve your dating life, self-esteem, and confidence. You can use hydrogen peroxide to obtain white teeth because it’s cheap and easy to apply. However, you have to take precautions, because it has side effects discussed below and you can search more website that talks about these effects like site.

1 – Increased Teeth Sensitivity

Hydrogen peroxide is an active bleaching agent because it penetrates your enamel deeply. It reaches even the underlying dentin layer of your teeth to remove all stains. Unfortunately, this deep penetration increases teeth sensitivity to hot and cold drinks. According to the journal, Medical Hypotheses, you might experience bleaching sensitivity even without stimulation of hot or cold beverages. This is a side effect that subsides after you discontinue using hydrogen peroxide.

2 – Mouth Irritation

Hydrogen peroxide that’s highly concentrated might make your dental formulas to cause sores and blisters inside your mouth. A milder solution of hydrogen peroxide might create a stinging sensation after rinsing your mouth. Langone Medical Center based in New York University notes that people who use whitening medications inaptly attribute irritation to hydrogen peroxide. You can clean your mouth with hydrogen peroxide, instead of applying it using a dental tray. This might reduce your risk of mouth irritation, sores, and blisters.

3 – Undesirable results

The results you achieve after using hydrogen peroxide to whiten your teeth might not be the results you wanted. You might not notice any change in the shade of your teeth after whitening, because your teeth had been heavily discolored. Or they might begin to appear translucent or gray because you whiten them too often. Additionally, hydrogen peroxide won’t work on your teeth if you have caps, fillings, crowns, or veneers.


Hydrogen peroxide risk of damage increases when you use a highly concentrated solution, leave it in contact with your teeth longer than a minute or apply it to your teeth more than once daily. Consult your dentist before using hydrogen peroxide to whiten your teeth to know the best application schedule and strategy that’s best for your situation.
