TouchWhite Laser Teeth Whitening in Hamilton, ON

If you’ve tried whitening before and hated the sensitivity (or the time commitment), TouchWhite is the alternative we’re excited to offer at Excel Dental. TouchWhite is Fotona’s laser-assisted tooth whitening approach that’s designed to work faster while being gentler on the tooth by directing the laser energy into the bleaching gel instead of heating the tooth itself.

Below, I’ll walk you through what TouchWhite is, why it’s different from traditional in-office whitening, what a typical appointment feels like, and who tends to get the best results. I’ll also include clinical before-and-after photos (hotlinked directly from Fotona) so you can see the kind of shade changes that are possible.

What is TouchWhite?

TouchWhite is a laser-assisted tooth whitening technique that uses Fotona’s Er:YAG dental laser wavelength (2940 nm) to activate the whitening gel more efficiently. The key detail is that this wavelength is strongly absorbed by water, and water is a major component of common bleaching gels. That means the laser energy can be absorbed in the gel rather than passing through and warming the tooth structure. Source

In practical terms, that “gel-first” energy delivery is what allows TouchWhite to shorten treatment time while aiming to reduce the unwanted thermal impact that can contribute to post-whitening sensitivity in some other approaches. Fotona TouchWhite brochure (PDF)

Why TouchWhite can feel different from other whitening

Most people don’t mind whitening itself. They mind what happens afterward: the zingy, temporary sensitivity that can show up when you drink cold water, breathe in winter air, or touch certain teeth with a toothbrush. Sensitivity can still happen with any whitening method, but TouchWhite is specifically designed to reduce the tooth’s thermal burden during activation.

• Laser energy is absorbed in the gel. Fotona describes the Er:YAG energy as being fully absorbed in the bleaching gel, helping avoid direct heating of the underlying tooth. Source
• Minimal thermal impact on the tooth. Because the gel is the primary absorber, the whitening gel can be heated effectively without “cooking” the tooth. Source
• Potentially faster appointment time. Fotona reports whitening speeds increased by 5–10 times compared to conventional approaches, which can translate into a shorter in-office whitening session. Source

TouchWhite is also frequently discussed as a more comfortable experience compared with some other laser-assisted whitening methods because the bleaching agent can spend less time on the teeth while still achieving a strong result. Source (PDF)

Clinical before-and-after photos

These are clinical images hosted by Fotona on their TouchWhite tooth whitening page. They’re intended to show real shade changes achieved in clinical settings. Results vary based on starting shade, enamel characteristics, and the type of staining (surface stains vs. deeper internal discoloration).

What to expect at your TouchWhite appointment

Every office has its own workflow, but most TouchWhite appointments follow a familiar whitening structure with a few important upgrades in comfort and efficiency:

• We confirm you’re a good candidate. Whitening works best on natural tooth structure. We’ll check for cavities, gum inflammation, worn enamel, exposed root surfaces, and old restorations that might affect comfort or shade matching.
• We protect your gums and soft tissues. Just like other professional whitening methods, we isolate and protect the gums so the whitening gel stays where it belongs.
• Bleaching gel is applied, then activated. The laser is used to activate the gel efficiently. Fotona describes this as heating the gel rather than the tooth structure, which is the “why” behind the gentler feel for many patients. Source
• Shade evaluation. We compare your before-and-after shade and talk about how to maintain results (and whether a future touch-up makes sense for your goals).

If you’ve had sensitivity with whitening in the past, tell us. There are practical ways to reduce that risk, including timing, desensitizing strategies, and making sure we’re whitening teeth that are healthy and stable first.

Who is TouchWhite best for?

TouchWhite is a great fit for people who want a noticeable change but don’t want to gamble on days of sensitivity afterward. It’s also a strong option when timing matters, like photos, interviews, weddings, or events, because Fotona positions it as significantly faster than conventional whitening activation. Source

You may be a good candidate if:

• You have yellowing from coffee/tea, red wine, or general aging.
• You want a brighter smile before cosmetic dentistry (for example, to help match future restorations to a lighter baseline shade).
• You’ve avoided whitening because of sensitivity in the past (we’ll still evaluate the cause of that sensitivity first).

And just as important, whitening may not be the best first step if you have untreated decay, active gum disease, significant enamel wear, or many visible crowns/veneers on front teeth that won’t change shade. In those cases, we’ll talk through alternatives so your end result looks even and natural.

FAQs

Is TouchWhite safe for my tooth?
Fotona describes TouchWhite as avoiding direct heating of the tooth because the Er:YAG energy is absorbed in the whitening gel rather than penetrating hard tissue or the pulp. Source

Will I get sensitivity afterward?
Any whitening can cause temporary sensitivity, but TouchWhite is designed to reduce thermal impact and shorten gel contact time. Fotona also includes a testimonial noting “no sensitivity” and “no over-bleaching,” but individual experiences vary. Source

How much whiter will my teeth get?
It depends on your starting shade and the type of staining. Many people see a meaningful jump in brightness after one visit, but not everyone will reach the same shade. The clinical photos above are good examples of real-world variability.

Does whitening work on crowns, veneers, or fillings?
No. Whitening changes the color of natural tooth structure, not restorations. If you have visible restorations on front teeth, we plan whitening carefully to avoid a mismatch.

Can TouchWhite help a tooth that looks grey after a root canal?
A tooth can darken after root canal treatment because the discoloration is often internal. In many cases, dentists can improve the appearance of non-vital (root canal treated) teeth using specialized whitening approaches. Clinical reporting on TouchWhite has described its use on both vital and non-vital teeth, depending on the case. The right plan depends on why the tooth changed color and what restorations are present. Source

Keeping your results looking great

After whitening, your teeth may be more prone to picking up stain for a short window. We’ll give you personalized guidance, but the basics are simple: go easy on coffee/tea/red wine for a bit, avoid tobacco, and keep up with professional cleanings so surface stains don’t “rebuild” over time.
