Your smile is one of your most noticeable features to friends and strangers alike. But when your teeth start to develop stains and discolouration, your self-confidence might suffer. Thankfully, professional teeth whitening solutions are available to help preserve your stunning first impression.

While many patients rely on store-bought whitening strips, the reality is that most over-the-counter options just can’t compare to the advanced knowledge and experience of an expert like Dr. El-Hawary. Get professional whitening results with the guidance of a dentist that puts your oral health first. We’ll explore some of the ways our Ottawa dental team can improve the look of your smile below.

How Does Professional Teeth Whitening Work?

Did you know that your teeth have pores similar to your skin? When you consume colour-staining substances such as wine and coffee, they are gradually absorbed in these pores and begin to impact the natural white shade of your teeth. Teeth whitening treatments work to dissolve those built-up stains and gently push the particles out through the pores. Whereas over-the-counter whitening strips cannot penetrate the enamel, professional solutions reach the inner layers of your teeth and eliminate years of accumulated discolouration.

Are Whitening Treatments Safe?

Yes, professional whitening treatments are safe for your teeth and won’t cause any damage. Since the whitening process aims to push out the stains, the active ingredients temporarily open the pores of your teeth. This may cause some temporary sensitivity, which is very common and will subside on its own. At our Downtown Ottawa dental practice, we’ll work to alleviate any concerns you may have and make sure you’re fully informed about your treatment.

In-Office Whitening


In addition to our professional grade kits for at-home whitening, we now offer in-office whitening treatments at Dow’s Lake Dental. In just one appointment, you can brighten your smile by up to eight shades! We’ll customize your treatment to ensure the best results and minimize any sensitivity. In the months that follow, you can continue to whiten at home with an included custom kit, perfect for touch ups.  Contact us today for more information about how you could achieve a stunning smile in just one session.

What’s the Most Effective Treatment for Whitening Teeth?

Most whitening products use similar active ingredients. However, since treatments like whitening strips are merely placed along the front surface of the teeth, they can miss areas of your smile and leave you with patchy, inconsistent outcomes. This can be an issue in particular for patients whose teeth are not perfectly in alignment.

At Dow’s Lake Dental, we’ll use custom-fitted whitening trays that ensure every surface of your teeth is adequately covered with the whitening solution to avoid inconsistencies and give you the stunning results you deserve.

Common Questions About Teeth Whitening

Unfortunately, most insurance providers do not cover teeth whitening treatment because it’s a purely cosmetic procedure. However, we do recommend contacting your provider personally as all plans may vary. For financing questions, call our Dow’s Lake office at

The better cared for your teeth are, the longer the whitening treatment will last. We offer a few recommendations to protect you from restaining your teeth:

  • Use a soft-bristled toothbrush
  • Use non-abrasive toothpaste
  • Avoid hot or cold drinks for at least one day post-procedure
  • Avoid staining agents like coffee and tobacco

Each patient has unique teeth, habits, and oral hygiene routines. All of these things will factor into how long your teeth stay pearly white after the treatment.

Avoiding staining agents, caring for your teeth, and coming in for regular checkups with Dr. El-Hawary will all contribute to your bright smile’s longevity.

Fluoride is a mineral that fights bacteria and plaque, which eat away at your tooth enamel, thereby preventing cavities. While our bodies naturally make fluoride, it’s also in certain kinds of toothpaste and some mouthwashes. 

Since fluoride helps to protect against cavities, we recommend using dental products that contain fluoride as part of your oral care routine. We also offer professional fluoride treatments that are highly concentrated and only take a few minutes to apply.
