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 cosmetic dental procedures available today due to its effectiveness, convenience, and gentle 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 absorbed by the dentin beneath. Teeth whitening treatments work by breaking down stains in your enamel, and brighter enamel allows more of the underlying dentin to show through. This smooths or repairs your enamel to also reflects 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 in a safe and professional cosmetic treatment, provides excellent results!
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, aging, and staining substances affect how much better shows through, which can influence tooth color.
Common Causes of Tooth Staining
- Coffee, tea, and red wine
- A thin enamel layer (genetics) that forms on enamel and attracts pigments
- Microscopic pores in the enamel that trap food particles and debris
- Dark beverages: coffee, tea, red wine, cola
- Foods with strong pigments: berries, sauces, soy
- 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 and 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
- Use an antibacterial mouthwash to kill bacteria and freshen breath
Use Gentle Whitening Toothpaste
Choose a non-abrasive whitening toothpaste that helps maintain brightness without damaging enamel or gums.
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.

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 many colors and intensities, including 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 oral use.
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 the whitening gel applied to the teeth. The light helps break down the whitening agents, which then penetrate and remove stains on the teeth more quickly and effectively.
Is LED Teeth Whitening Safe?
Yes, LED teeth whitening is considered safe when used properly and with approved whitening gels. The LED light produces minimal heat compared to other light, resulting in less risk for enamel erosion, bad caviar and gum irritation. However, like any cosmetic treatment, 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 typically last 3-6 months, depending on your lifestyle and oral hygiene habits. Factors that can affect longevity include:
- Brushing and flossing twice daily
- Avoiding dark staining foods and beverages (e.g., coffee, red wine)
- Reducing tobacco use or quitting smoking altogether
- Using whitening toothpaste and certain dental rinses 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, or just feeling better about your appearance. At Lashed Toronto, we use safe, professional-grade whitening products that provide visible results without damaging your smile.
