Are Teeth Whitening Strips Safe? Side Effects and Safe Use

Whitening strips are, quite often, one of the best methods for whitening your teeth at home (and even dentists will use powerful strips, on occasion). However, one big question is whether whitening strips can damage teeth. The answer? Maybe. But, if you’re careful, the chances of this happening are minimal.

Let’s explain.

What do whitening strips actually do?

While they seem like magic, there’s a lot going on with whitening strips. So, let’s give you a quick overview of how they work before we take a dive into whether they’ll damage your teeth.

How they whiten your teeth

Most teeth whitening strips contain hydrogen peroxide (or some other form of peroxide). When you use them, the hydrogen peroxide will penetrate the enamel of the tooth. It then enters the dentin. Here, it bleaches pigments known as chromogens. By bleaching them, the teeth are whitened.

Ingredients explained: hydrogen peroxide vs non-peroxide

You can also find non-peroxide teeth whitening strips. While they are generally safer to use than hydrogen peroxide strips, they are not as effective. They don’t penetrate the teeth. They don’t bleach anything. Instead, they’ll lift stains from the surface of the teeth.

While non-peroxide solutions will work for some people, they rarely give the dramatic results that people want.

Are whitening strips safe when used correctly?

Yes. For most people, whitening strips are safe when used correctly. There are a few caveats, though.

Backed by dentists and studies

Firstly, only purchase teeth whitening strips that have been backed up by dentists and studies. Some of the cheaper strips on the market aren’t, and it can be tough to vouch for their safety.

Quality strips will have been backed by dentists and studies, which indicate that they are safe to use. This is assuming that you follow the instructions properly, but more on that part soon.

Why quality matters

Don’t buy cheap teeth whitening strips. Quality matters.

You want teeth whitening strips that are classed as enamel safe. For example, some of the cheaper options on the market don’t contain hydrogen peroxide. Instead, they contain an ingredient known as chlorine dioxide. Some people claim that chlorine dioxide is more effective than hydrogen peroxide. It might be. The problem is that studies have shown that this ingredient will strip the enamel from your teeth, giving you less protection. This can result in far more sensitive teeth, and increased staining in the future.

Cheaper products should be avoided altogether, since you have no idea what ingredients are included in the product. You really don’t want to put random things into your mouth, do you?

We recommend buying a quality product such as Crest 3D White Strips.

What are the possible side effects?

There are some side effects to using teeth whitening strips. Not many, and a few of the problems can be avoided.

Sensitivity, and why it’s usually temporary

Most people will experience some mild sensitivity when they use hydrogen peroxide teeth whitening strips. This is because the chemical is penetrating the tooth enamel. It is getting deep inside there. This could cause light irritation of the nerves in the tooth.

Thankfully, if you are using the product as per instructions then the sensitivity issues should clear up quickly. You just might need to avoid overly cold or hot food or putting too much pressure on your teeth for a few hours.

Gum irritation, and how to avoid it

The chemicals in teeth whitening strips can be quite harsh. While they are fine on your teeth, getting them on your gums can cause serious irritation. It can be quite painful.

Basically, avoid getting the whitening strip on your gums. Be careful when using them. This is another reason why you should be using high-quality whitening strips. It means that they are the right size for your teeth, ensuring that they don’t need to come into contact with your gums at all.

Enamel concerns: myth vs reality

If you’re using hydrogen peroxide teeth whitening strips, then you’re fine. No study has shown that hydrogen peroxide will wear down tooth enamel. Your teeth might get a little bit sensitive for a while due to irritation of the nerves in your teeth from the bleaching agent, but you should be fine.

You should avoid whitening strips that contain chlorine dioxide, though. Studies have proven that chlorine dioxide will strip enamel from your teeth.

How to use teeth whitening strips safely

To minimise any potential risks and ensure a safe and effective teeth whitening experience, follow these guidelines:

✓Choose reputable brands

Opt for well-known and trusted brands that adhere to safety standards. At Advanced Whitening, we offer high-quality products like Crest 3D White Whitestrips Professional Effects Luxe Edition, known for their effectiveness and safety profile.

✓Follow instructions carefully

Always read and follow the instructions provided with your teeth whitening strips. Pay close attention to the application time and frequency of use.

✕Avoid overuse

More isn’t always better. Using strips more often or for longer than recommended can increase the risk of sensitivity and gum irritation. Stick to the recommended treatment duration.

✓Maintain good oral hygiene

Brush and floss regularly before using teeth whitening strips. This helps remove plaque and debris, allowing the strips to work more effectively and reducing potential irritation.

✓Listen to your body

If you experience significant or persistent sensitivity or gum irritation, stop using them and consult your dentist.

✓Consider your dental health

If you have existing dental issues like cavities, gum disease, or exposed roots, consult your dentist before using teeth whitening strips.

✕Not a substitute for professional cleaning

Teeth whitening strips are designed to address surface stains. They do not replace regular dental check-ups and professional cleanings.

Who might need extra caution?

Some people might need to take extra care when using whitening strips.

People with dental restorations or gum issues

If you’ve had dental restorations carried out, or you have gum issues, then your teeth might be a little bit more sensitive when using whitening strips. This is because your teeth will have less of a protective layer on them.

If you have gum disease (for instance), then don’t use strips at all. It will irritate them.

Safer alternatives for sensitive teeth

Using whitening toothpastes might help if you have sensitive teeth. You can also use non-peroxide solutions, just bear in mind that these options might not be as effective as peroxide-containing teeth whitening strips.
