Teeth whitening has become a popular trend in recent years, with many people seeking to achieve a brighter, more vibrant smile. One of the most common methods of teeth whitening is using whitening gels, which are applied to the teeth and left to work their magic. However, with so many products on the market, it can be challenging to know which ones are safe and effective.

What is carbamide peroxide?

Carbamide peroxide is a common ingredient in teeth whitening gels. It is a type of hydrogen peroxide that is derived from urea, and it works by breaking down into hydrogen peroxide and urea when it comes into contact with water. Hydrogen peroxide is a powerful bleaching agent that can remove stains and discoloration from the teeth, while urea helps to prevent tooth sensitivity.

Is carbamide peroxide safe and effective?

  • Teeth whitening gels that advertise they contain 35% carbamide peroxide are generally considered safe when used as directed. However, it is essential to follow the instructions carefully and avoid overusing the product, as this can lead to tooth sensitivity and other issues.
  • In addition, some people may be more sensitive to carbamide peroxide than others. If you have a history of tooth sensitivity or gum problems, it is advisable to consult your dentist before using any teeth whitening products. It is always a good idea to contact a dental professional to share your teeth whitening goals and to determine the best plan considering your individual needs and dental history. 
  • It is also worth noting that some whitening gel products that contain active ingredients such as but not limited to carbamide peroxide may need to be refrigerated to maintain (1) the % of active ingredient and (2) the effectiveness of the active ingredient.   

How do I use teeth whitening gel safely?

  • Start with a clean slate: Before applying the whitening gel, brush and floss your teeth to remove any plaque or debris that may interfere with the whitening process.

  • Use a small amount: You only need a small amount of whitening gel to achieve results, so avoid overloading the tray or brush with product.

  • Avoid contact with gums: Be careful not to get the whitening gel on your gums, as this can cause irritation or sensitivity.

  • Limit use: Limit your use of teeth whitening gel to the recommended duration and frequency to avoid overexposure.

  • Monitor for sensitivity: Keep an eye out for any signs of tooth sensitivity or gum irritation and stop using the product if these symptoms occur.


In conclusion, teeth whitening gel products that contains 35% carbamide peroxide can be a safe and effective way to achieve a brighter, more vibrant smile. However, it is essential to use the product as directed, highly recommended that you follow good oral hygiene practices to maintain your oral health, and strongly suggested that you communicate your teeth whitening goals to a dental professional to determine the best plan considering your individual needs and dental history.
