Teeth Whitening Q & A

What causes my teeth to need whitening?

Your teeth might be stained, discolored, or dull for a number of reasons. Some of the more common causes are:

  • Tobacco use
  • Foods or drinks with pigments, such as coffee, tea, dark sodas, and red wine
  • Poor oral hygiene
  • Medical treatments, such as high blood pressure medications, chemotherapy, and antihistamines


Your genetics and biology might also play a role since people with more porous or transparent enamel tend to exhibit more pronounced staining.

What are my teeth whitening options?

There are numerous teeth whitening treatments available today, such as special toothpaste, rinses, and over-the-counter strips and gels. Dr. Ko recommends custom-made bleaching trays for all of his patients looking to achieve a more luminous their smile.

Custom-made bleaching trays are considered to be the most effective and safest whitening treatment according to the American Academy of Cosmetic Dentistry. When your whitening trays aren’t designed to mold perfectly to your tooth, as is the case with over-the-counter and at-home treatments, the whitening gel can leak out, causing irritation to your gums and reducing the effectiveness of the whitening process.

What’s the process of teeth whitening with custom-made trays?

When you come in for custom-made teeth whitening trays, Dr. Ko first cleans and examines your teeth for any existing dental concerns, like gum disease or cavities. Next, he takes an exact impression of your teeth, which he uses to make plastic trays that fit perfectly onto your smile.

Once you receive your plastic trays, you fill them with a small amount of bleaching solution and wear them for a specified amount of time each day, typically an hour. After two to three weeks, you should reach your maximum whitening level.

What are the side effects of teeth whitening?

Teeth whitening is a safe and painless procedure with few side effects. At most, patients will experience some sensitivity in their teeth to cold substances. This usually disappears within three days of completing the whitening process.
