In-Office Whitening
In-office whitening is the faster option, as it’s done at the clinic in a single visit. During the treatment, we protect your gums and soft tissue.
At Leslie North Dental, we offer two professional whitening options: in-office and take-home, and help you choose the right one. Curious if this procedure is right for you? Let’s talk it through at a consultation.

At Leslie North Dental, the whitening process starts with a personalized consultation to ensure your teeth and gums are healthy enough for treatment. A cleaning may be recommended if necessary to improve results. Your whitening goals are then discussed to decide whether in-office whitening or custom take-home trays are more suitable.
In the in-office option, your gums are protected and a professional whitening gel is applied, with the treatment completed in a single monitored visit. If you choose take-home trays, custom-fitted trays are created for you along with clear instructions for safe and effective use.

Many patients compare in-office teeth whitening to store-bought options like strips that cost around $50. The difference is in strength, safety, and results.
Most over-the-counter strips contain about 3-10% hydrogen peroxide. Our professional whitening gel contains 16-25% peroxide, making it significantly stronger and more effective.

The whitening agent works on surface stains, such as those caused by coffee, tea, red wine, tobacco, dark-coloured foods, and natural aging. However, you cannot remove the deeper and internal stains resulting from medications, dental fluorosis, past trauma, or non-vital teeth with any type of teeth whitening.
In short, no. Whitening only works on natural enamel, so crowns, veneers, bonding, and fillings stay the same shade even as your natural teeth lighten.
