Introduction to Peroxide Whitening Strips

Peroxide whitening strips have become a popular at-home teeth whitening option for people looking to brighten their smiles and lift stains from their tooth enamel.

What are Peroxide Whitening Strips?

Peroxide whitening strips are thin, flexible strips that are coated with a whitening gel containing peroxide. This peroxide works to bleach stains and lift discoloration, whitening teeth 1-2 shades when the strips are used consistently and as directed.

These strips can be purchased over-the-counter from many drugstores and retailers. They are also available through dental professionals, like Onuge’s proprietary peroxide whitening strips made with a residue-free formula.

How Do Whitening Strips Work?

The whitening gel on the strips contains peroxide, either hydrogen peroxide or carbamide peroxide. When the gel comes into contact with your teeth, the peroxide releases free radicals that work to lift extrinsic stains on the surface of the teeth.

Peroxide also penetrates deeper, entering the dentin layer of the tooth, where it lifts intrinsic stains found inside the tooth structure. It does this by reaching the chromogens - pigmented molecules that cause staining and tooth discoloration.

The peroxide breaks down and oxidizes these chromogens, effectively bleaching them and whitening the teeth through this chemical reaction. Consistent use over a 10-14 day period allows for optimal stain removal and teeth whitening results.

The Effectiveness of Peroxide Whitening Strips

When used properly and consistently over time, peroxide whitening strips can safely and effectively brighten your smile by 1-2 shades. Optimal whitening results come from daily use of the strips over a 10-14 day period.

Expected Whitening Results

Peroxide whitening strips can lighten teeth up to 2 shades when used exactly as directed by the manufacturer. Most users see a 1-2 shade improvement in the whiteness of their teeth in as little as 3-5 days of continued use.

The peroxide bleaches and lifts extrinsic stains on the enamel surface caused by factors like coffee, red wine, smoking, etc. It is also effective at lightening intrinsic stains that occur inside the dentin from age, genetics, and enamel erosion.

For best whitening results, consistent use for the full duration of 10-14 days is recommended. This allows the peroxide enough contact time to fully penetrate the teeth and produce maximum stain removal.

Factors Affecting Results

The type and concentration of peroxide used on the whitening strips impacts their efficacy. Products with a higher peroxide content will produce increased whitening, but also raise the risk of tooth sensitivity.

Consistent daily use as directed provides better whitening results than sporadic or reduced application. Following the product instructions is important to get the best whitening from your strips.

Proper oral hygiene is also essential to avoid new stains forming while using the whitening strips. For individuals with heavy staining or discoloration, professional in-office whitening treatments are likely to be more effective than drugstore whitening strips.

The Safety of Peroxide Whitening Strips

When used exactly as directed, peroxide whitening strips are safe for tooth enamel. However, improper use or certain pre-existing dental conditions can increase sensitivity risks.

Common Side Effects

Increased tooth sensitivity and gum irritation are common side effects of using peroxide whitening strips. These symptoms are usually mild and temporary in nature.

Sensitivity and irritation sensations typically start during the time the strips are in use and last for a few days afterwards. Using whitening strips with higher concentrations of peroxide increases the likelihood of experiencing sensitivity.

Properly following the product directions can help reduce the chances of side effects. Consult your dentist if sensitivity persists beyond 3-5 days after whitening.

Dental Conditions to Avoid

Individuals with thin enamel or enamel that is worn away should use caution with peroxide whitening strips, as they are at higher risk for sensitivity. The same applies for people with dental restorations like fillings, crowns and bridges.

Those with untreated tooth decay or cavities, or inflamed gums and periodontal disease, should consult their dentist before using whitening strips. Peroxide can seep underneath dental restorations and cause irritation.

Whitening is not recommended for anyone presently showing signs of the above dental conditions. It is important to get your dentist’s approval before using peroxide whitening strips if you have any pre-existing tooth sensitivity or oral health issues.

When used properly, Onuge’s peroxide whitening strips are generally safe, but those with the above conditions should take extra precautions.

Maintaining Whitening Strip Results

The brighter, whiter smile achieved through consistent use of peroxide whitening strips like those from Onuge can be maintained long-term by following proper oral hygiene habits and limiting intake of staining foods and drinks.

Making small adjustments to your daily oral care routine and diet can go a long way in preserving your results and keeping your teeth looking their whitest. Here are some tips:

Oral Hygiene Tips

One of the most important things you can do is stick to a regular oral hygiene regimen. Be sure to brush your teeth thoroughly twice a day and floss once daily to remove any plaque buildup or debris that can lead to stains. Getting professional cleanings and dental checkups every 6 months can also help remove hardened tartar and surface stains.

Avoiding tobacco and smoking is also essential, as nicotine is notorious for causing yellowing and discoloration of teeth. When drinking darker beverages like coffee, tea, or red wine, use a straw to minimize contact with your teeth. Rinsing your mouth with water after consuming any staining foods or drinks can help wash away residue.

It’s also a good idea to brush your teeth after eating or drinking anything that may cause staining. Occasionally using whitening strips for touch-ups will help maintain your results between professional whitening treatments.

Dietary Changes

Making small tweaks to your diet can also reduce exposure to staining. Opt for drinking water instead of darker sodas, juices or sports drinks. Limit consumption of coffee, berries, soy sauce, curries, and other foods that can cling to teeth and cause discoloration. When you do indulge in staining items, be sure to drink them through a straw and rinse afterwards.

Eating foods rich in calcium, like milk, yogurt and leafy greens, will strengthen your enamel and help resist new stains. Reducing your sugar intake will minimize risk of cavities and tooth decay, which can lead to discoloration. Drinking milk or eating yogurt provides an extra calcium boost, while avoiding constant snacking limits staining opportunities.

By taking care of your teeth and minimizing staining culprits, you can make that brighter smile last after whitening with Onuge’s peroxide strips!
