How long does the session take?

The treatment is a self-application session, and lasts between 20 to 60 minutes depending on the discoloration of your teeth and how white you want to whiten them.

What is the difference?

Lightlu uses the latest LED technology and our professional grade whitening gel. Our system has proven to yield superior results with little to no sensitivity when compared to other whitening systems.

Does it hurt?

Most people feel no pain or sensitivity whatsoever after sessions. A small percentage of clients may feel some tooth sensitivity, especially if they are dehydrated or consume very cold/hot foods or drinks within two hours after the whitening session. Any sensitivity is typically short term and gone within 24-48 hours.

Will the teeth whitening sessions work on crowns, veneers and fillings?

The teeth whitening gel will remove staining from existing dental work and take it back to the original color- but no whiter than the original color of the crown, veneer, or filling. Our goal is to have the process clean up the existing dental work and whiten the natural teeth to match for a nice even smile. The process cannot whiten them beyond the original color of the material used at the time of placement.

Should I consider Lightlu?

Yes. People that feel better about their smile often smile more, studies have shown. Smiling more has also been shown to improve one’s happiness. Everyone deserves to smile and feel confident about it.

Is a Lightlu self-administered treatment for everyone?

The Lightlu self-application session provides dramatic results for anyone who wants to whiten their teeth. This includes people with teeth that have been stained by smoking or by substances such as coffee, tea, soda, wine and other consumable items. We are often told that our sessions “blow the others away”. Seeing really is believing with our sessions.

What if my teeth do not get whiter?

We have not experienced a customer that did not improve the whiteness of their teeth with sessions. The Lightlu Guarantee protects the customer in that he/she would not have to pay for their first initial 20 minute session if their teeth did not improve 3 shades (only applies to clients with an average tooth shade of S22 or darker.).

How white will my teeth get?

After undergoing a self-application whitening session with Lightlu, teeth shades will brighten typically 6-10 shades. Individual results will depend on your current tooth shade, session time, and the composition of your teeth. Your end result will be a whiter, healthier smile. Everyone’s teeth are different and will have a natural stop point. We recommend a 60 minute session for optimal results and to remove all layers of staining.

How long will the whitening last?

This varies from person to person and depends on your diet and lifestyle. However, with proper maintenance, the session can last up to 1 year.

Is Lightlu safe for teeth whitening?

Scientific research has shown that the active ingredients in the Lightlu gels are safe and effective. Our gels and whitening equipment are manufactured in an FDA registered facility and have been used throughout the dental and cosmetic community for years. Lightlu products do not change or damage the structure of the teeth; it merely lifts and removes the stains, making your teeth whiter.
