TEETH WHITENING
All About LED Teeth Whitening
LED teeth whitening is a non-invasive cosmetic treatment designed to help lighten the appearance of teeth by reducing surface stains and discoloration. It’s one of the most popular smile-enhancing services in salons and spas because it offers noticeable results with minimal sensitivity and no downtime. However, it’s important to note that LED whitening is not permanent and will require occasional maintenance to preserve a bright, white smile.
The enamel is the outermost layer of your teeth, and it plays a key role in their natural color. The lightness of your teeth is determined by how light is reflected off the enamel and how it interacts with the dentin beneath it. Genetics affect the thickness and smoothness of your enamel, and thinner enamel allows more of the underlying dentin to show through. The smoother or rougher your enamel is also influences how light is reflected, affecting the overall color of your teeth.
How Does LED Teeth Whitening Work?
This treatment involves the application of a whitening gel, often made from hydrogen peroxide, carbamide peroxide, or an all-natural alternative. The gel is activated by an LED (Light Emitting Diode) light, which helps accelerate the whitening process by speeding up the breakdown of stain molecules on the tooth surface.
LED light alone doesn’t whiten teeth — it works in combination with the whitening agent. The treatment typically lasts 30 to 60 minutes and is safe when performed correctly with appropriate products.
Understanding Tooth Color and Stains
The enamel is the outermost layer of your teeth and plays a big role in how white they appear. Light reflects off the enamel and interacts with the dentin, the layer beneath it. Factors like genetics, age, and enamel thickness affect how much dentin shows through, which can influence tooth color.
Your teeth can become stained due to:
-
A thin protein layer (pellicle) that forms on enamel and attracts pigments
-
Microscopic pores in the enamel that trap food particles and debris
Common Causes of Tooth Staining
-
Tobacco use (smoking or chewing)
-
Dark beverages: coffee, tea, red wine, cola
-
Foods with strong pigments: berries, sauces, curry
-
Poor oral hygiene
-
Natural aging (as enamel thins and dentin becomes more visible)
LED Whitening Aftercare Tips
To keep your smile looking bright after treatment, follow these aftercare guidelines:
🕒Avoid Staining Foods & Drinks (First 24–48 Hours)
Try to avoid:
-
Coffee, tea, cola, red wine
-
Berries, soy or tomato-based sauces, curry
-
Dark or acidic drinks like some fruit juices
Limiting these even beyond the first 48 hours can help prevent re-staining.
🪥 Maintain Excellent Oral Hygiene
-
Brush twice daily with a fluoride toothpaste
-
Floss daily to remove plaque and debris between teeth
-
Avoid brushing too aggressively to protect your enamel
🦷 Use Gentle Whitening Toothpaste
Choose a non-abrasive whitening toothpaste that helps maintain brightness without damaging enamel.
🚭 Avoid Smoking or Tobacco Use
Tobacco is one of the fastest ways to re-stain your teeth. Avoiding it will significantly extend your results.
💧 Stay Hydrated
Drinking water helps rinse away food particles and neutralize acids in the mouth that can lead to staining.
🔁 Book Touch-Up Treatments
For best results, consider scheduling touch-up treatments every 6–12 months, depending on your habits and how prone your teeth are to discoloration.

Everything You Need to Know About LED Teeth Whitening
What is LED Light?
LED stands for Light Emitting Diode—a technology that emits light when an electrical current passes through it. LED lights come in various colors on the visible light spectrum, including blue-violet and red, and are commonly used in cosmetic treatments due to their low heat emission and energy efficiency. Unlike traditional bulbs, LEDs remain cool to the touch and are safe for use near the body.
Does LED Light Whiten Teeth?
LED light itself does not whiten teeth—but it plays an important role in the whitening process. It works by activating and accelerating the effects of a whitening agent (usually hydrogen peroxide or carbamide peroxide). This allows the whitening gel to break down stains on the teeth more quickly and effectively.
At Lashed Toronto, we use a safe, peroxide-free, all-natural whitening gel alongside LED light to brighten your smile without causing tooth sensitivity or enamel damage.
Is LED Teeth Whitening Safe?
Yes, LED teeth whitening is considered safe when used properly and with approved whitening products. Unlike UV light, LED light is visible-spectrum only, meaning it does not emit ionizing radiation and carries no known cancer risk.
Side effects are typically minimal but may include temporary tooth sensitivity or gum irritation, especially in clients with pre-existing dental issues. Our whitening process is designed to minimize discomfort and is safe for most individuals.
How Long Do Results Last?
Results can last 6 to 8 months, depending on your lifestyle and oral hygiene habits. For longer-lasting results, we recommend:
-
Brushing and flossing twice daily
-
Avoiding dark-staining foods and beverages (e.g., coffee, red wine)
-
Reducing tobacco use or quitting smoking altogether
Smoking, poor oral hygiene, and certain dietary choices can cause faster re-staining of the teeth.
Is LED Teeth Whitening Worth It?
Absolutely! A brighter smile can boost your confidence in everyday situations—from speaking with others to taking photos. Our LED teeth whitening treatment at Lashed Toronto takes just 30 to 60 minutes and provides a safe, noticeable improvement in the brightness of your smile.
