While it's not plastic surgery, laser teeth whitening is considered a cosmetic dental procedure that shows significant improvement to your teeth's brightness — up to 10 shades brighter. Bleach is applied to each tooth while a laser generates heat that enhances its effectiveness, ultimately speeding up the process and leading to quick, dramatic results. But what else does the procedure involve? How much does it cost? And is it safe and effective? Find the answer to those questions and more, here in Laser Teeth Whitening 101.

It's not a long process, but it is precise. Check out the step-by-step breakdown below:

• Prep:
  • The color and shade of your existing teeth are determined using a shade indicator.
  • A picture of your teeth is taken to see a before/after comparison.
  • Your lips are coated with a protective SPF lotion containing moisturizers.
  • A cheek retractor is inserted into the mouth, and cotton rolls are placed under the lips.

• Procedure:
  • A protective coating is placed over the gums to protect your mouth and gums from the bleaching gel.
  • A bleaching gel consisting of hydrogen peroxide and thickening agents is applied to the front of your teeth to keep the solution on the surfaces of your teeth.
  • A bleaching light or laser is shined on the teeth to activate the bleaching process.
  • Some whitening systems consist of three 15-minute sessions in one sitting.
  • The gauze and the liquid dam materials will be monitored between sessions to ensure that the mouth's soft tissues are safe and dry.

• Post-Whitening:
  • After the treatment, you will need to avoid lipstick and certain food and drinks (coffee, soda, etc.) for a few days as the pores of enamel are more susceptible to absorbing stains. Your teeth will also be more sensitive to cold food items (ice cream, cold beverages, etc.).

Most agree that laser teeth whitening is the most effective whitening treatment. And with that comes cost. Here are the associated costs you can expect when going the laser route:

• Financial. Most dental insurance plans don't cover laser teeth whitening, so chances are you’ll have to pay out of pocket. The price varies significantly depending on your location, your dental provider, and the laser whitening system they use.
• Time. Here's where you can make up for the price, as nearly every procedure takes just an hour to complete.

There's no doubt that laser teeth whitening is the most expensive of all teeth whitening options, but for a good reason. It's quick and effective results are a combination that's tough to beat.

You got your teeth laser whitened. You love it. But according to the American Academy of Cosmetic Dentistry, professional teeth whitening can last six months to two years. So how do you keep those pearly whites so white? Here are a few specific things you can do to maintain your new bright smile:

• Avoid dark-colored beverages and foods that cause staining over time.
• Drink with a straw to reduce the effect of staining beverages.
• Brush with whitening toothpaste to help whiten and protect your teeth.
• Visit your dentist for regular checkups and cleanings.
• Schedule a follow-up treatment every six months if necessary.

If you prefer to pass on the laser in your mouth, there's a variety of other options to choose from. There are two categories for non-laser whitening: over-the-counter (OTC) products or professional systems. The latter can be applied either at home or in-office, and will achieve better results than OTC due to higher concentrations of the bleaching agent and their application method. OTC products come in a variety of forms:

• Toothpaste and rinses
• Gel used in trays
• Whitening strips
• LED devices
• Whitening chewing gum
• Whitening paint-on gel

Here are a few more things to keep in mind when considering laser teeth whitening:

• Your dentist will determine if you're a viable candidate for the procedure.

• Multiple treatments may be required for your desired results.

• At-home bleaching trays may be required for your desired results.
