Teeth whitening strips are a popular way to make your smile look brighter. They’re easy to use, sold over the counter, and promise fast results. But do they really work? And are they safe? This post will break down how these strips work, what they’re made of, what to expect, and how to get the best results.
How Teeth Whitening Strips Work
Most whitening strips use peroxide to whiten your teeth. When applied, the peroxide breaks down stains on the surface of your teeth. This process is called oxidation. It helps lift yellow and brown stains caused by things like coffee, tea, wine, or tobacco.
Some strips use hydrogen peroxide, while others use carbamide peroxide. Hydrogen peroxide works faster, but carbamide peroxide lasts longer. Both work in similar ways and are common in many whitening products.
Types of Whitening Strips
There are a few types of whitening strips available:
- Peroxide-based strips: These are the most common. They use hydrogen or carbamide peroxide to bleach stains.
- Charcoal strips: These use activated charcoal to remove stains. They may not work as well and can sometimes be abrasive.
- Non-peroxide strips: These use other ingredients like sodium bicarbonate or plant enzymes. They’re often gentler but take longer to show results.
- Enzyme-based strips: These newer strips use ingredients like papain or bromelain, which come from fruit and help clean surface stains.
What’s in Whitening Strips?
The ingredients in whitening strips vary, but here are the most common ones:
- Hydrogen Peroxide: This is the main whitening agent that helps remove deep stains.
- Carbomer and PVP: These help the strips stick to your teeth and hold the gel in place.
- Sodium Hydroxide: Helps control the pH of the product.
- Flavorings: Some strips add mint or other flavors to make the experience more pleasant.
How to Use Whitening Strips
Using whitening strips is simple, but there are some steps you should follow for the best results:
- Start with clean teeth. Brush and floss before applying the strips.
- Apply the strips to dry teeth, not wet ones. This helps them stick better.
- Follow the instructions. Most strips stay on for 5 to 30 minutes, depending on the brand.
- Avoid eating or drinking during and after use.
- Rinse your mouth when finished. Wait 30 minutes before brushing your teeth.
Don’t wear strips overnight or use extra accessories like UV lights unless advised by a dentist. These can cause tooth sensitivity or damage your enamel.
Are Whitening Strips Safe?
Most over-the-counter whitening strips are safe when used as directed. Some are even approved by the American Dental Association (ADA), like Crest 3D Whitestrips. Still, some people experience tooth sensitivity or gum irritation.
Higher concentrations of peroxide can lead to enamel wear if used too often. Some strips are not made to fit every mouth, which can cause uneven whitening or expose your gums to the gel. If you have crowns, fillings, or veneers, whitening strips won’t change their color.
To be safe, talk to your dentist before starting any whitening treatment—especially if you have sensitive teeth or other dental work.
What to Look For in Whitening Strips
When choosing a whitening strip, keep these points in mind:
- Check the ingredients. Look for peroxide if you want stronger results.
- Avoid harmful additives. Stay away from chlorine dioxide, which can damage enamel.
- Comfort. Some strips are thicker or more flexible than others.
- Price vs. results. Cheaper strips might not work as well or may need longer use.
Professional Whitening vs. Store-Bought Strips
Professional whitening uses stronger peroxide concentrations—sometimes up to 40%. This means faster results and less room for error. Custom trays help the gel stay on your teeth and off your gums.
Store-bought strips usually contain 10% to 22% peroxide. They still work, but results take longer and may not be as even. Some strips also slip or don’t fit well, making the process less effective.
Preparing Your Teeth for Whitening
Getting ready before whitening helps you get better results:
- Visit your dentist for a cleaning and check-up.
- Brush and floss before applying the strips.
- Follow the instructions exactly.
- Use fluoride or sensitivity toothpaste if your teeth feel sensitive afterward.
How to Keep Your Teeth White After Whitening
Keeping your smile white takes effort. Here are some tips:
- Cut back on foods that stain, like coffee, red wine, and tomato sauce.
- Rinse your mouth with water after meals and drinks.
- Use a whitening toothpaste once or twice a week.
- Don’t smoke or use tobacco.
- See your dentist regularly for cleanings and check-ups.
Benefits of Teeth Whitening
Whiter teeth can do more than improve your smile. Many people feel more confident after whitening. It can also help reduce surface stains and encourage better oral hygiene. Some whitening ingredients even fight plaque and bacteria.
A Quick Look at the History of Whitening
Teeth whitening isn’t new. Ancient Egyptians used ground pumice stone mixed with vinegar. Victorians tried charcoal. Today’s peroxide-based strips began gaining popularity in the 1980s and continue to be widely used.
