Is it Safe to Whiten Teeth with Hydrogen Peroxide? ›

Like many chemicals, hydrogen peroxide is only safe in small doses. While hydrogen peroxide is generally recognized as safe for whitening, the key lies in using it in appropriate concentrations. Anything stronger than a 3% concentration is dangerous, and many whitening products dilute the solution even further.

Hydrogen peroxide is an inexpensive household product you probably have on hand right now. When used carefully, it can be an effective way to whiten your teeth. But if used incorrectly — in concentrations that are too high or if used too often — it can cause serious and sometimes expensive tooth damage.

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.

Risks of Hydrogen Peroxide

The website Dentaly.Org stated the following "The dilution of hydrogen peroxide considered safe to use is 3%. Any higher, and you could risk damaging your enamel for good. Even then, using it for prolonged periods of time can still cause damage.

It's safe to use over-the-counter peroxide oral rinse, which has roughly 1.5% to 3% hydrogen peroxide.

Baking-powder eliminates stains on the surface of your teeth and lemon juice as we already said has multiple components that lighten teeth. Just mix a teaspoon of baking powder and a teaspoon of freshly squeezed lemon juice and brush your teeth with the paste this mixture will work wonders in just two minutes.

Hydrogen Peroxide as a Gum Disease Treatment

This more severe form of gum disease can cause your teeth to loosen or even fall out. Because it can kill harmful bacteria and break up plaque, dental professionals have been using hydrogen peroxide since the early 1900s to prevent and treat periodontitis.

Carbamide peroxide and hydrogen peroxide are commonly used in whitening interventions and can readily permeate dental hard tissues. Temporary tooth sensitivity and gingival inflammation are the most common adverse effects of vital tooth whitening.

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.

Which is better, salt water rinse or hydrogen peroxide? ›

The fact that dental professionals choose peroxide over saltwater should tell you one thing: saltwater gargles are fine in a pinch, but hydrogen peroxide rinses are actually preferable. Peroxide rinses mix water with 3% hydrogen peroxide to help clean, brighten, and prevent gum damage.

No, hydrogen peroxide doesn't dissolve tartar, but it can help remove the plaque that hardens into tartar.

Baking soda can be used with some water to remove the stains on the surface of the teeth. It can also be used with hydrogen peroxide to enhance its whitening effects. Baking soda can be used by individuals with regular toothpastes too. It is also used commercially in some teeth whitening products and toothpastes.

For deeper cleaning, people safely can mix baking soda with a small amount of hydrogen peroxide to create a toothpaste.

However, combining hydrogen peroxide from your medicine cabinet with toothpaste to make a homemade teeth whitener is not recommended. Peroxide in toothpaste and other dental products bleaches teeth to make them whiter. However, the concentration of peroxide in these products is low and carefully controlled.

Hydrogen peroxide can irritate the gums and may be too harsh on fillings, crowns, and dental implants. Your dentist may suggest its use as an oral rinse if diluted with Listerine or water. Because of its harshness, it should only be used by dental recommendation.

Hydrogen peroxide can also exert a direct cytotoxic effect via lipid peroxidation. Ingestion of hydrogen peroxide may cause irritation of the gastrointestinal tract with nausea, vomiting, haematemesis and foaming at the mouth; the foam may obstruct the respiratory tract or result in pulmonary aspiration.
