Having a beautiful smile starts with having white teeth. Unfortunately, our teeth can turn yellow over time. This may be due to our diet, lifestyle, and other factors. Teeth whitening helps reverse this darkening effect to give you a whiter and brighter smile. But how does teeth whitening brighten your smile? Almost all teeth whitening treatments use high concentrations of Carbamide Peroxide or Hydrogen Peroxide. The peroxide becomes activated when it comes into contact with your teeth surface. It penetrates deep into your teeth and breaks down the internal stains. The yellowness from your teeth is removed and you are left with a whiter and brighter smile.

What are my options for professional teeth whitening?


There are so many different ways to whiten your teeth. Here are some of the most common ways:

  • Teeth whitening toothpastes
  • Peroxide-based whitening mouthwashes
  • Do-it-yourself bleaching trays such as Crest Whitestrips
  • Take home custom whitening trays
  • Professional teeth whitening at the dentist

It's always a good idea to discuss your whitening treatment with your dentist beforehand. It's important to identify what is causing your teeth to turn yellow before seeking any type of treatment. Additionally, factors such as tooth sensitivity, teeth stains, gum recession, existing restorations, etc. need to be taken into consideration.

What's the advantage of teeth whitening at the dentist?

Only your dentist is allowed to use the highest concentrations of Peroxide solution

If you want the absolute best teeth whitening results, you should talk to your dentist first. Whitening treatments offered by the dentist are far more effective than over-the-counter alternatives. This is because only your dentist is allowed to use the highest concentration of Peroxide solutions. The reason for this is that high concentrations of peroxide can be very dangerous if used unsupervised. It can cause your gums to burn or lead to tooth sensitivity, which is sometimes permanent. Talk to your dentist about your different teeth whitening options to see which is best for you and to earn if you're a good candidate for in-office teeth bleaching.

How does in-office teeth whitening work?

A barrier is placed to protect your gums from the Peroxide gel prior to starting your whitening treatment

Teeth whitening at the dentist is often times referred to as in-office teeth whitening. It so happens that this is also the most effective way to bleach your smile. In-office teeth whitening is simple, quick, and extremely effective. The procedure is typically performed in under one hour. Expect your teeth to become several shades whiter after treatment. Here's a brief overview of how in-office teeth whitening is typically performed:

Preparation for teeth whitening procedure

Your dentist will examine your teeth before starting your teeth whitening. They look for any fillings or crowns which may interfere with the bleaching process. They also look to make sure your teeth are not too sensitive and identify exposed root regions which need to be protected during treatment. Once it is determined that you are indeed a good candidate for in-office teeth whitening you are ready to start your treatment.

In-office teeth whitening

Most of the teeth whitening process is typically performed by the dental assistant under the direct supervision of your dentist. Your dental team will start off by isolating your gum tissue. This is done by placing a barrier on your teeth and gums. The barrier protects your gums against the harmful effects of the strong bleaching gel. Next, your dental team will carefully apply the whitening gel to your teeth. They will pay close attention to make sure the bleach is applied evenly to all of your teeth surfaces that are planned for whitening. The bleaching gel will remain on your teeth for the duration of the whitening procedure. This typically ranges from 15 minutes up to one hour. Most bleaching systems also make use of a UV or LED light. This special light helps accelerate the breakdown of the bleaching gel to make it even more effective. You will remain in your chair until the whitening process is completed. If your teeth start to hurt, call out to the dentist and they will terminate treatment if necessary.

Post-op instructions

Your dental team will now remove the whitening gel and the barrier from your mouth. Feel free to rinse and spit and take time to clean up your mouth. You're all done and ready to show off your beautiful, pearly whites! Be sure to follow the post-op instructions. This includes avoiding staining products for the next several days.

How do take-home custom whitening trays work?


Custom take-home trays are the next best way to whiten your smile. For this method, your dentist will make custom bleaching trays. These custom trays are made from moldings of your teeth and allow you to whiten your teeth at the convenience of your own home. Here's how take-home teeth whitening trays work:

Fabricating your custom trays

Custom trays need to fit precisely to your teeth to work properly. Your dentist will fabricate your custom trays using scans or impressions of your teeth. They leave just enough space on the trays to accommodate the bleaching gel. Custom trays sit snugly against your teeth and directly apply the whitening gel to desired teeth surfaces.

Wearing your custom trays

Start by brushing your teeth thoroughly to clean them. Carefully insert the bleaching gel into your custom trays. Apply the gel evenly onto areas planned for whitening. This includes the front surfaces of your front 6 to 10 teeth. Position the trays gently onto your teeth and make sure not to contaminate them with excess saliva. Gently remove any excess gel that has poured onto your gum tissue to prevent gum irritation. Allow the custom trays to sit in your mouth as per the bleaching gel manufacturers recommendation or until you experience extreme tooth sensitivity. Wear times vary for different whitening gels and range from 30 minutes to several hours.
