Is It Safe To Use Baking Soda & Hydrogen Peroxide To Whiten Teeth? ›

Baking soda for yellow teeth

The abrasiveness of baking soda can can cause weakened enamel and increase tooth sensitivity. Certain preparations claim to combine the hydrogen peroxide and baking soda in the proper ratio to keep the baking soda from thinning the enamel, but it's not a gamble dentists want you to take regularly.

Hydrogen peroxide (H₂O₂) is a weak acid and baking soda (NaHCO₃) is a base compound. When you combine the two, there is an exothermic reaction that generates carbon dioxide gasses. The reaction helps break apart grease and organic stain molecules to make them easier to remove from surfaces.

When a chemical burn occurs, the area becomes mildly sore, turns white, and will eventually flake off.

In accordance with EU law, over the counter home whitening kits in the UK contain too little hydrogen peroxide (0.1%) to noticeably lighten the teeth. The legal limit for a dentist to use is between 0.1% and 6% hydrogen peroxide.

Remember, you shouldn't whiten your teeth more than two times per week, whether you're adding hydrogen peroxide, baking soda or both. For everyday use, try a whitening toothpaste that has baking soda already built-in and may also have fluoride to help prevent cavities and strengthen your teeth.

The longer hydrogen peroxide stays in contact with your teeth, gums, or tongue, the more damage it can cause. That is why whitening treatments that contain hydrogen peroxide are only applied for a limited amount of time. Most products recommend a maximum time of 1 – 2 minutes, once or twice a week.

Use this paste in moderation; no more than 2-3 times a week. Too much baking soda can break down enamel, which may lead to sensitivity. Remember that this paste does not have any added fluoride benefit.

Combine 1 part Dawn dish soap and 2 parts hydrogen peroxide in a small bowl. Stir to combine. Dip stain in the mixture and then sprinkle baking soda on it. Scrub with the toothbrush.

Does swishing hydrogen peroxide in your mouth whiten your teeth? ›

It is an ingredient in many teeth whitening solutions for use both at home and in the dentist's office. A simple hydrogen peroxide mouthwash may help remove mild stains. However, a person should avoid leaving hydrogen peroxide solutions on their teeth for extended periods.

Hydrogen peroxide is used widely in professionally and self-administered products. Hydrogen peroxide is a highly reactive substance which can damage oral soft tissues and hard tissues when present in high concentrations and with exposures of prolonged duration.

Fortunately, there are ways of making your yellow teeth white, from improving your oral hygiene and diet to visiting the dentist and having them professionally whitened. There's no need to feel ashamed of your smile anymore.

Use Baking Soda and Hydrogen Peroxide

Baking soda can help get rid of plaque that's on your teeth while hydrogen peroxide is an antibacterial agent that can whiten your teeth and keep them free of germs. When you mix these two together, you'll create a paste-like substance.

You can use hydrogen peroxide to whiten your teeth since it has natural bleaching properties. But using it on your teeth carries the risk of getting tooth sensitivity and gum inflammation. Some kinds of toothpaste and mouth washing products contain small concentrations of hydrogen peroxide.

Generally at this concentration you would need to have your teeth in contact with the 3% hydrogen peroxide for about 5 hours a day for about 2-3 weeks to have meaningful tooth whitening, which is very difficult to do with a watery liquid.
