In-office whitening uses professional-strength hydrogen peroxide activated by specialized LED light technology to deliver transformative results in a single appointment. Unlike over-the-counter products that take weeks and produce modest results, our systems achieve six to ten shades whiter in just one hour — supervised by dental professionals who protect your gums and manage sensitivity throughout. Whether you're preparing for a wedding, job interview, or simply want a brighter smile, in-office power whitening is the fastest, most effective way to get there. Sedation options are available for patients with dental anxiety.
During your appointment, we apply professional-strength whitening gel — containing 25-40% hydrogen peroxide — directly to your teeth and activate it using advanced LED light technology. The gel penetrates the enamel to break down deep stains and discoloration at the molecular level. Three to four activation cycles of 12-20 minutes each produce cumulative whitening, with each cycle building on the results of the last.
Professional-strength gels contain significantly higher concentrations of active ingredients than at-home systems, and our LED lights enhance the whitening process dramatically. Your gums are protected with barrier gels and rubber dams, and our team monitors your comfort and results throughout the appointment. You walk out with noticeably whiter teeth the same day — perfect for weddings, job interviews, graduation photos, milestone birthdays, or any occasion where you want to look your best.
Sedation Options for Patients with Dental Anxiety
Your One-Hour Whitening Visit Step by Step
We take before photos, match your current shade with our professional shade guide, and gently polish your teeth to remove surface debris. This ensures maximum whitening gel contact and effectiveness.
We place cheek retractors for access, apply protective barrier gel to your gums, position a rubber dam, and provide safety eyewear. Your oral tissues are completely protected throughout the entire process.
Professional-strength whitening gel is applied and activated with our specialized LED light. You go through three to four cycles of 12-20 minutes each, with fresh gel applied between cycles for optimal, cumulative results.
We rinse away the gel, take after photos for comparison, and apply desensitizing treatment. You see your new smile immediately and receive detailed aftercare instructions to protect and maintain your results.
Your teeth look their brightest immediately after treatment — most patients achieve six to ten shades whiter. You may notice slight sensitivity, which is completely normal. During the first 24-48 hours, teeth naturally rehydrate and you might see them darken by a half shade — this is your enamel reabsorbing moisture and is expected. After 48 hours, your shade stabilizes at its final whiteness. Front incisors typically lighten the most, while canines remain slightly darker due to their thicker enamel.
Professional in-office whitening results last one to three years depending on your habits and lifestyle. Coffee, tea, red wine, and tobacco are the biggest factors in re-staining. We recommend touch-up appointments every 6-18 months to maintain your brilliant smile. Take-home whitening trays can extend your results between professional treatments. With proper care and periodic maintenance, you can keep your smile looking its best indefinitely.
About 60-70% of patients experience mild to moderate sensitivity for 24-48 hours after whitening, and it resolves completely within two to three days. We have protocols to minimize discomfort: start using desensitizing toothpaste two weeks before your appointment, and take ibuprofen 30-60 minutes before to preempt sensitivity. During treatment, we monitor your comfort closely and can adjust gel concentration or cycle timing if needed.
We apply professional-strength desensitizing gel immediately after whitening and provide prescription-strength desensitizing toothpaste to use for three to five days post-treatment. Avoid hot and cold foods and beverages for 48 hours — room temperature is your friend during this period. If sensitivity persists beyond three days, contact us immediately. We can apply additional desensitizing treatments and may recommend a short course of fluoride gel at home.
The first two days after whitening are crucial for maintaining your results. Your enamel is more porous and susceptible to staining during this period. Avoid coffee, tea, red wine, tomato sauce, soy sauce, berries, curry, beets, chocolate, and any deeply coloured foods or beverages. Avoid smoking or tobacco products entirely. These contain pigments that can penetrate your freshly whitened enamel and compromise your results.
Stick with light-coloured foods and drinks during this window: water, milk, white wine, chicken, fish, tofu, white rice, bananas, cauliflower, potatoes, and white cheese. If you do consume any coloured beverages, use a straw and rinse your mouth with water immediately afterward. These simple habits protect your investment and keep your smile brilliantly white through the critical rehydration period.
In-office whitening works beautifully for most patients with healthy teeth and gums. Yellow and brown stains — from coffee, tea, wine, tobacco, and natural aging — are the most responsive to whitening treatment. Patients with realistic expectations about achievable results and a willingness to follow aftercare instructions are ideal candidates.
In-office whitening will not change the colour of existing crowns, veneers, or composite fillings. If your front teeth contain these restorations, we can whiten your natural teeth and then match your restorations to your new shade afterward. Grey stains from medications like tetracycline respond poorly to whitening and may require veneers or composite bonding instead. Patients with very thin enamel may experience heightened sensitivity and should discuss alternative approaches. We require healthy gums before proceeding — if you have active gum disease, cavities, or enamel erosion, we address these first.
