Teeth whitening has increasingly become a favoured DIY hack, thanks to easily accessible drugstore strips or the latest influencer-promoted LED kit. But while it might seem like a simple treatment, whitening your teeth can be more complicated than it looks.
With so many products to choose from, it’s hard to tell what really works and what’s worth investing in. That’s where professional whitening makes all the difference.
To help you understand your options, we spoke with one of our Teeth Whitening experts, Dr. Joan Daniel. She shared everything you need to know about the two professional teeth whitening methods used at our clinics, what they cost, and how to choose the right treatment for you.
Professional teeth whitening is a cosmetic dental treatment performed under the supervision of a dentist, and according to Dr. Daniel, this matters for two important reasons.
First, it’s safer because a dental professional makes sure your teeth and gums are protected, checks for any cavities or sensitivities, and ensures the whitening gel is applied correctly. This prevents common issues such as gum irritation, peeling, or unnecessary sensitivity that can occur if your at-home project goes wrong.
Second, it’s faster and more effective. In-office whitening uses stronger, dentist-grade hydrogen peroxide, which allows you to see results immediately. This means you can achieve a smile that’s 4–5 shades brighter in just a single 1-hour session. In contrast, at-home methods usually require weeks of repeated use to achieve noticeable changes.
These popular treatments can help you achieve a youthful, vibrant look with just a few strategic pokes.
At HealthOne, offers two types of teeth whitening options for our patients:
1. In-Office Teeth Whitening
In-office teeth whitening is performed directly by a dental professional using a high-concentration whitening gel, often paired with a specialized light to enhance results. This method can brighten your smile by 4–5 shades in a single visit, making it both the safest and fastest whitening option available.
2. Take-Home Custom Whitening Trays
Take-home whitening involves custom-fitted trays made in the clinic and filled with dentist-grade whitening gel that is stronger and more effective than drugstore strips or LED kits. Results develop gradually over 1–2 weeks, offering a more reliable and noticeable change compared to over-the-counter products.
Note: Over-the-counter products, such as whitening strips, toothpastes with peroxide, and LED-light kits — can lighten teeth over time, but require more frequent use, have lower peroxide concentration, and carry a higher risk of misuse. These should be used with caution and consulted by your dentist.
When it comes to professional teeth whitening cost, both in-clinic and take-home options vary depending on the treatment you choose. In-clinic whitening is approximately $350 for a 1-hour session, and the price remains the same each time. Because the whitening gel used in-office is stronger, most patients see such significant results — typically 4–5 shades brighter — that they often don’t need multiple sessions.
Take-home whitening kits typically range from $250–$300, depending on how many kits you purchase and how much whitening gel you need to replenish over time. Each kit is a flat fee, but unlike a package deal, patients still need to buy additional whitening gel separately if they want to continue treatment at home. Take-home whitening requires consistent use and tends to take longer to show results compared to an in-office visit.
Over-the-counter whitening products, such as strips, toothpastes, and LED kits, can cost anywhere from $5 to over $100, but they must be used more frequently to achieve and maintain noticeable results. Whitening from these methods is generally slower, less predictable, and not as dramatic.
The key differences between these whitening methods come down to three things:
In Ontario, teeth whitening is not covered by OHIP because it is considered a cosmetic treatment rather than medically necessary.
Our Treatment Coordinators can help create a plan that works for your budget. Most whitening treatments are done on the same day, but flexible arrangements may be available upon request.
According to Dr. Daniel, the answer is yes, absolutely. Professional teeth whitening is safe, fast, effective, and fully customizable, and it is always performed under the supervision of a dental expert. This combination makes it one of the most reliable ways to brighten your smile. It can significantly boost your confidence, enhance your appearance, and help you feel your best. In fact, many patients notice a major difference after just one in-office session.
Visiting a professional in Toronto ensures you’re whitening your teeth in the safest environment possible.
At HealthOne Dental, our team first checks for any cavities, gum issues, sensitivities, and restorations like crowns or veneers. This step is important as only natural tooth enamel can change colour. If underlying issues aren’t addressed first, whitening results won’t be as effective.
When you invest in professional teeth whitening, you are doing more than just lightening your teeth—you are investing in yourself.
Not only will you witness better results and longer-lasting brightness, but you're also choosing a safer application, which leads to better long-term dental health. With personalized care and the assurance of realistic expectations for your teeth, the true benefit is the undeniable boost in your confidence.
It’s an investment in your smile, your health, and your future happiness.
