Whitening
A Brighter Smile—Fast
Whether you’re preparing for a wedding, graduation, vacation, or simply want to feel more confident, professional teeth whitening is one of the quickest ways to refresh your smile.
At Metral Dental, Dr. John Christensen offers in-office Zoom whitening to safely brighten your teeth in a single appointment. Because the treatment is performed under professional supervision, you can achieve significantly whiter results than most over-the-counter whitening products.
What is Zoom Teeth Whitening?
Zoom is a professional whitening system that uses a powerful whitening gel activated during your appointment to lift stains from the enamel.
The treatment is designed to whiten teeth affected by:
- Coffee
- Tea
- Red wine
- Tobacco
- Aging
- Everyday staining
Many patients notice their smile becomes several shades brighter after just one visit.
Why Choose Professional Whitening?
While whitening toothpastes and strips can help with minor surface stains, professional whitening offers several advantages:
- Faster results
- More noticeable whitening
- Even whitening across your smile
- Professional supervision for safety and comfort
- Higher-strength whitening agents than products available in stores
What Happens During Your Appointment?
Your appointment typically takes about an hour, but it depends on the patient.
First, we’ll examine your teeth and gums to make sure whitening is appropriate for you. We’ll also discuss your goals and answer any questions before beginning.
Once you’re ready, we’ll carefully protect your lips and gums so that only your teeth are exposed. A professional-strength hydrogen peroxide whitening gel is then applied to the teeth.
The gel works by penetrating the enamel and breaking apart the molecules that cause stains and discoloration. Unlike whitening toothpastes, which only remove surface stains, Zoom whitening can lift stains from within the tooth structure.
During your appointment, the whitening gel is activated with the Zoom LED light and refreshed several times to maximize the whitening effect. Throughout the procedure, we’ll monitor your comfort and ensure everything is progressing safely.
When the treatment is complete, the gel is removed and you’ll be able to see your brighter smile right away. Many patients leave with teeth that are several shades whiter after just one visit.
Will My Teeth Be Sensitive?
Some patients experience temporary tooth sensitivity after whitening. This usually improves within a day or two.
We’ll discuss whether Zoom is the right choice for you and provide recommendations to help minimize sensitivity.
How Long Do Results Last?
Results vary depending on your habits and lifestyle.
To help maintain your brighter smile:
- Brush and floss regularly
- Attend routine hygiene appointments
- Limit foods and drinks that stain teeth
- Consider occasional touch-up whitening as recommended
Is Zoom Whitening Right for Everyone?
Professional whitening works best on natural teeth.
It may not whiten:
- Crowns
- Veneers
- Fillings
- Bonding
-
If you have restorations or certain types of tooth discoloration, Dr. John Christensen can discuss other cosmetic options that may better achieve your goals.
Frequently Asked Questions
How white will my teeth get?
Every smile is different. Most patients achieve several shades of improvement, although results depend on your natural tooth colour and the type of staining present.
Does Zoom whitening hurt?
Most patients find the treatment comfortable. Some temporary sensitivity afterward is normal and usually resolves within 24–48 hours.
How long does the appointment take?
Plan for approximately one hour.
Can anyone get their teeth whitened?
We’ll examine your teeth first to make sure whitening is appropriate. Cavities, gum disease, or other dental concerns should usually be treated before whitening.
