Are Whitening Strips Bad For Your Teeth

Indulging in our favourite foods and drinks is self-care for the majority of us. However, some of these favourites may lead to stubborn teeth stains. While visiting a dentist is an option, it may not always go as planned and can end up costing more than expected. This is where convenient teeth whitening strips come in handy for at-home teeth whitening. But the question is: Are teeth whitening strips safe for your teeth? Let’s dig deeper!

How Do Teeth Whitening Strips Work?

Teeth whitening strips are thin, transparent films covered with hydrogen peroxide or carbamide peroxide gel on one side. These compounds are chemical ingredients used in professional whitening treatments by dentists, though in much lower concentrations in over-the-counter home whitening products.

These main ingredients are responsible for the bleaching effect. When applied for 30 minutes, the strips gradually start to whiten teeth and minimise tooth discoloration to some extent.

Are Whitening Strips Safe For Teeth?

Whitening strips are safe to use when used in moderation. Overusing them by reapplying every hour or so, and leaving them on longer than recommended could cause some issues:

  1. Teeth Sensitivity: Excessive use can lead to tooth sensitivity, resulting in pain when consuming cold beverages or exposed to air.
  2. Gum Irritation: Prolonged application may cause temporary but painful gum irritation.
  3. Enamel Damage: Misuse or overuse can weaken tooth enamel, causing increased teeth sensitivity or severe pain upon application.

If you’re facing such issues, simply discontinue use. Consult a dental expert on using whitening strips, especially if encountering existing dental issues. They can give advice on safe usage and whitening alternatives based on your dental history.


Teeth whitening strips are an effective method for whitening teeth. However, caution must be observed to avoid damaging gums and causing sensitivity due to excessive use. Consulting a Turramurra dentist before using whitening strips, especially with existing dental issues, is important. Remember, maintaining healthy teeth is just as crucial as having whiter teeth!
