Get a Lighter, Brighter Smile

Teeth whitening can be a great option for patients who have an upcoming special occasion or are looking for an effective way to change the look of their smile. At Pain Free Laser Clinic and Beauty Bar, our technicians offer in-office treatment for all our patients in Niagara Falls and surrounding areas.

What is Professional Teeth Whitening?

Teeth whitening done by a professional is one of the safest and most effective ways to get rid of stains and lighten your teeth’s color.

As you age, your teeth become more likely to discolor because of food and other substances. Over time, particles build up on teeth and attract stains from things like coffee, tea, berries, and tobacco.

The bleaching agents we use during our teeth whitening treatment are designed to undo the aesthetic effects of aging and staining, resulting in lighter coloured teeth.

How Teeth Whitening Works

Teeth whitening uses bleaching agents that are peroxide-based. Oxygen acts on the tooth enamel as the active ingredient breaks down, creating the whitening effect. 


In-Office Teeth Whitening in Niagara Falls

In-office teeth whitening takes about 2 hours at your dentist office. First, a barrier is applied around your gums to protect them, then a thin layer of gel is applied and chemically activated on each tooth. We repeat this process a few times, until the desired shade of white is achieved.

Teeth Whitening FAQs

Teeth whitening isn’t a permanent solution to whiten your smile.

If you continue to expose your teeth to foods and drinks that cause staining, you will likely begin to see the whiteness fade after a few months.

If you avoid these foods and drinks after your teeth whitening treatment, you may just need a touch up after a year or so.

Sensitivity is a short-term side effect to teeth whitening. For most patients it fades away within a few days after a whitening session.

To minimize any discomfort, we recommend that you use an anti-sensitivity toothpaste prior to treatment and for at least two weeks following your treatment.

Yellow and brown-coloured stains respond the best to teeth whitening treatments.

Grey, blue and purple-coloured stains tend not to respond to whitening at all. For teeth with these types of stains, patients may be better candidates for cosmetic treatments such as porcelain veneers or dental crowns.

No, teeth whitening only works on natural teeth. It does not work on existing dental restorations such as porcelain veneers or dental crowns.

If veneers or crowns are part of your treatment plan, teeth whitening should take place before you receive your dental restorations.

If used under the supervision of a qualified dentist, it is very unlikely that teeth whitening will damage your dental enamel.

Always consult with your dentist to ensure that you are using any teeth whitening products safely.

Dental insurance does not usually cover the cost of teeth whitening because it is a purely cosmetic procedure with no health benefits for your teeth.
