In-Office Whitening vs. Home Whitening

In-Office Whitening vs. Home Whitening

As many as 80% of U.S adults aged 18 to 49 would like to enjoy a whiter smile. Fortunately, this is easier than ever thanks to the wide range of whitening treatments now available. However, with so many to choose from, how do you know whether to opt for in-office whitening or do the job yourself at home? To help you to make this decision, here’s what you need to know about the main areas of comparison between in-office and home teeth whitening.


For many people, one of the biggest benefits of in-office whitening is that the application of the treatment is carried out by a professional. When you choose in-office whitening, your dentist will use special protective equipment to shield your gums, tongue and other soft tissues of your mouth so that they don’t become irritated by coming into contact with the whitening agent. This helps to prevent soreness and sensitivity. Needless to say, a dentist also has a much better view of and access to your mouth. This means that the application of the whitening agent can be guaranteed to be more even and consistent, ensuring that you achieve better results. At-home kits can be tricky to apply whilst take-home trays can overflow. The application of whitening agents by a professional is considered to be much safer and produce significantly better results.

Strength of the bleaching agent

There are various different strengths of bleaching agents that are used in whitening products. However, only in-office whitening treatments are cleared for using the strongest grades of bleach. What this means is that you can expect to achieve brighter, whiter teeth more quickly with professional treatment. If you choose at-home whitening, you can expect to require more sessions in order to obtain the shade that you are looking for.


Budget is something that is important to most people when it comes to choosing cosmetic dental treatments. Make no mistake, home whitening solutions are typically considerably cheaper than going into your dentist’s office for an appointment. However, this lower cost is reflected in their various disadvantages of home whitening:

-       The trickiness of applying whitening agent yourself

-       The leaks that can occur with whitening trays

-       The inconsistent results that are more likely when you DIY your whitening treatment

-       A lesser degree of whitening with more treatments due to the lower strength of whitening agent that can be safely used in at-home solutions

-       Results that don’t last as long as those achieved in-office


As a result, many patients feel that in-office whitening represents much better value for money and a great investment in the long-term appearance of their smile.

Length of results

When you invest in a brighter, whiter smile, you want it to last as long as possible. As such, it is important to be aware of the difference in result length between in-office and at-home whitening treatments. Since in-office treatments use a stronger grade of bleach, the results that they produce have been consistently shown to last longer than those which can be achieved using at-home kits.
