Laser Teeth Whitening - Dental Screening

The dental screening with your dentist determines if you're an eligible candidate for the treatment. The dentist checks your reaction to the bleaching agent, and they assess the shade of your teeth to determine how many treatment sessions they think you'll need.

If they feel you qualify, they'll book an appointment for the whitening treatment. You'll also receive a quotation and most dentists requirement full settlement in cash after the completion of the procedure. Some might ask for a 50% deposit after you conclude the screening process.

The Whitening Treatment

On the day of the treatment, your dentist sits you in the chair. They then apply a dental protectant to your gums. They coat your teeth in the bleaching agent and use a laser device to activate the gel, causing the bleaching effect.

The dentist waits a few minutes, removes the gel, and does touch-ups on areas they think need more work.

It might take them several passes before they get the effect they desire. After they feel you have a consistent whitening effect, they suction off the bleaching formula, and you have a set of beautiful white teeth.

Your Follow-Up Appointment

The first follow up will be a month or two after your first appointment to see how your teeth are doing.

Unfortunately, laser teeth whitening is not a permanent treatment, and you'll need to schedule biannual follow-ups to keep your smile white, bright, and beautiful.

How Long Does the Laser Teeth Whitening Procedure Last?

Laser whitening treatments will require maintenance, and you'll need a touch-up every six months, depending on your lifestyle choices.

For example, if you drink red wine and smoke cigarettes, you'll probably need another appointment sooner than someone with sober habits.

The Final Verdict 

Overall, we wouldn't recommend laser whitening treatment, especially given the other options available in the market at a fraction of the cost.  It's effective, but it's expensive.

Fortunately, there's a low-cost solution that produces similar results, and you don't need to go to your dentist's office for an examination – sound good?
