Teeth Whitening Pens vs Strips vs Bleaching | To Keep Your Teeth Clean, White and Healthy

Proper brushing and flossing on a daily basis will help keep your teeth clean and healthy. But if you feel like your smile could be brighter, you may want to consider a teeth whitening treatment session. Here's what you need to know before getting started.


The terms "whitening" and "bleaching" are often used interchangeably, but there's actually a difference between them (see also 'Teeth Whitening vs Teeth Cleaning'). 

According to the Food and Drug Administration (FDA) the term “whitening” is used to describe the process of restoring teeth to their natural color by removing stains and debris from the tooth surface. 

Unlike whitening, "bleaching" agents (such as hydrogen peroxide or carbamide peroxide) penetrate your tooth's enamel, which alter the tooth's color beyond its natural shade by affecting the dentin layer of your teeth.

Teeth Whitening Pens vs Teeth Whitening Strips

Teeth whitening strips can effectively whiten your smile, but those with harsh chemicals in their formulas like chlorine dioxide, can painfully destroy the enamel on your teeth and increase the risk of tooth decay. Even if the teeth whitening strips do not contain harmful ingredients, users may experience irritation because ill fitting strips can cause gum lines soreness. On the other hand, to avoid irritation you can choose a product meant for those with more sensitive teeth.

      1. Are teeth whitening pens worth it?

      As a temporary treatment and a quick fix, this is beneficial. However, use it with caution. Dentists generally recommend using tooth whitening pens. While you should pay attention to the active ingredients, these are not likely to increase your teeth' sensitivity like other whitening treatments.

      2. Do teeth whitening strips really work?

      Basically, yes. You can whiten your teeth quite significantly with teeth whitening strips within a few days. Over-the-counter whitening treatments are rarely as effective as in-office procedures. In addition, they are also associated with certain risks, including sensitivity and inflammation of the gums.

      3. Is bleaching your teeth bad?

      In addition to tooth sensitivity, too frequent teeth whitening can result in enamel damage and gum recession. Despite this, there is no formal standard for the frequency with which teeth whitening can be performed safely. That is why getting advice from a dentist and adhering strictly to product instructions are crucial.

      4. What is the best and safest way to whiten teeth?

      In the comfort of your own home, you can whiten your teeth in the following ways:
      - Use hydrogen peroxide or baking soda as over-the-counter whitening options.
      - Consider purchasing items marked with the Seal of Acceptance of the American Dental Association (ADA).
      - You should avoid foods and beverages with bright colors.

      5. What is the least harmful way to whiten teeth?

      It is recommended by the American Academy of Cosmetic Dentistry that you use custom trays provided by your dentist for the most safe and effective teeth whitening procedure at home. Gel could leak out of teeth whitening trays that don't fit properly, damaging your gums.

      6. Do whitening pens damage teeth?

      They didn't discover any noticeable negative effects. You may be concerned about how a teeth whitening pen will impact your current dental work. All peroxide whiteners do not work on dental restorations, which is important to note. This indicates that following a teeth whitening procedure, your dental work might need to be replaced.

      7. Are teeth whitening trays better than  teeth whitening strips?

      While less well-known than teeth whitening strips, whitening trays are a far better alternative. They enable more even, broad covering of the teeth by using custom-molded trays and a peroxide-based whitening gel. This results in faster whitening processes and noticeably brighter smiles.

      8. How long do whitening pens last?

      Whitening pens require anywhere from two days to a week. They give minimal results that are frequently short-lived.
