How Long Does Teeth Whitening Take?

There are a number of reasons you may have stained or discolored teeth. Your food and drink choices as well as your oral hygiene, medication use, and other factors may make your teeth an undesirable color. 

Fortunately, Dr. Amin Samadian’s team can whiten your teeth and help you achieve a whiter and brighter smile without any discomfort. You can opt for teeth whitening treatments before a special event or on a more regular basis.

How Teeth Whitening Works

To begin the process, Dr. Amin Samadian will clean and polish your teeth to ensure the whitening gel is being placed on the clean surface of your teeth. During a teeth whitening procedure, chemicals will be used to penetrate your teeth’s enamel, the hard, outer surface layer of your teeth that protects against tooth decay. 

Hydrogen Peroxide is typically the main component of many teeth whitening processes. With Zoom teeth whitening, a light-activated gel is made using hydrogen peroxide to safely penetrate the teeth. This light-activated method will professionally bleach them from the inside out while keeping the structure of your tooth unchanged. 

Teeth whitening also involves the use of a special tray, that’s specifically tailored to fit your teeth and mouth. Through the use of a tray, Dr. Amin Samadian can ensure that his potent whitening substance will cover all of your teeth equally without touching the gums. The active ingredients in the whitening substance can break down and deliver oxygen to your teeth’s enamel so you can enjoy a smile that’s up to eight shades brighter. 

Dr. Amin Samadian uses Zoom in-house whitening, which is an extremely safe procedure. You don’t have to worry about any serious sensitivity or other side effects that you may face with over-the-counter teeth whitening treatments. In the event that you do experience any sensitivity between sessions, let Dr. Amin Samadian know and he’ll stop the cycle.

You can take the 3D printed whitening trays as well as Zoom Night White take-home gel with you so that you can whiten your teeth in the comfort of your own home.

How Long the Teeth Whitening Process Takes

The amount of discoloration on your teeth will dictate how long your treatment will take. However, in most cases, it will take about 90 minutes per appointment. The number of appointments necessary will depend on your unique goals but typically patients are happy with the results after one Zoom in-house whitening appointment. Additional upkeep can be accomplished through the take-home whitening trays and Night White take-home gel. 

Compared to other teeth whitening methods such as at-home whitening strips, you’ll find professional teeth whitening to be a quick, comfortable procedure. You’ll be free to return to work and your daily activities right away. It is important to note that the results of Zoom in-house color correction will vary, therefore you may not achieve the same results as a friend or family member that has had the same treatment done.
