Are you thinking of whitening your teeth? Maybe you’re wondering where to begin. There are many whitening options out there, from relatively inexpensive over-the-counter whitening solutions, including strips, toothpastes, and gels, to more expensive in-office treatments. Read on to learn about whitening strips and why you may or may not want to give them a try.

What are Teeth Whitening Strips

Whitening strips are small plastic strips with a hydrogen peroxide gel that you apply to your teeth. Depending on the manufacturer's instructions, whitening strips can be used for up to 30 minutes a day for up to two weeks for a noticeable whitening result.


Teeth whitening strips do work. Will they make your teeth really white, though? It all depends on the origin of your stains and your teeth’s natural colour. Strips can remove stains caused by drinking coffee or red wine and smoking. However, they may not remove stains occurring from health issues or reactions to medications. If you use the strips as directed, you should see results in about 7-10 days. There are more advanced whitening strips claiming results as early as three days. Once you complete a full cycle, results can last up to six months. To help your teeth stay whiter longer, avoid foods and drinks that stain teeth.


Regular teeth whitening strips are priced according to the number of strips in a pack. You may also check with your dental office to see if they sell professional strips. These strips contain stronger, whitening ingredients. Strips are a very affordable and great way to try whitening your teeth, especially if you’re considering other in-office whitening treatment options (such as lasers), which can be much more expensive.

Ease of Use

Whitening strips are so easy to use. The most difficult part may be remembering to use them. They come with an upper and lower row strip. To use the teeth' white strips, you can typically apply them to the front teeth and wear them for around 30 minutes. Follow the instructions on the packaging or consult a dental professional.

Pros and Cons of Using Whitening Strips

Teeth whitening strips are considered to be a convenient, quick and affordable way to brighten your teeth at home. It's important to consult a dental professional before using these strips, particularly if you already have existing dental issues or concerns. There are both pros and cons to using a teeth-whitening strip.


The main advantages of teeth-whitening strips might include:

  • Affordability: Tooth whitening strips are usually cheaper than getting professional teeth whitening treatments.
  • Ease of use: Using whitening strips for teeth is relatively easy, which makes them good for people who want to whiten their teeth at home.


Some concerns might arise when using whitening strips for teeth. These include:

  • Efficacy vs. Professional Treatments: Teeth whitening strips may not be as effective as professional in-office treatments. Results might also vary depending on the severity of discolouration and how well the instructions are followed.
  • Repeated Use: Achieving desired results with teeth whitening strips requires consistent use. This process can take time and may need to be repeated to maintain results, depending on the product and the individual.

Side Effects

Teeth-whitening strips are a popular choice for brightening your smile at home. The prolonged use of teeth whitening strips might cause teeth sensitivity. It's important to follow the instructions carefully to avoid this. Furthermore, the strips might irritate your gums, leading to redness and swelling. If this happens, stop using the strips and consult a dental professional for advice.
