Glo science pro
GLO Science Pro is a home tooth-whitening system that uses peroxide gel and a lighted mouthpiece as directed.
The short answer
GLO Science Pro is a home whitening system that combines peroxide gel with a mouthpiece and light; it should be used only as its instructions and dental assessment indicate. The gel, not the light alone, is the primary whitening material.
How is peroxide applied to the tooth during treatment?
The system places peroxide against the tooth surface for a set application period. Peroxide can pass through enamel and alter colored molecules, while the mouthpiece helps position the gel and light according to the product design.
How can you use the whitening gel according to its directions?
Read the product directions, keep gel off the gums, and use the supplied amount and treatment time. A dental check should come first if you have decay, cracked teeth, gum disease, restorations, or unexplained sensitivity.
When should a dentist assess discolouration or inflamed gums?
Ask a dentist before use if one tooth is discolored, pain is present, or the gums are inflamed. Stop and seek advice for persistent burning, marked sensitivity, swelling, or an uneven result.
How will whitening affect fillings, crowns, and veneers?
Ask whether the discoloration is suitable for whitening and whether fillings, crowns, or veneers will remain unchanged. Ask how to adapt treatment for sensitivity and whether a custom tray would fit better.
Frequently asked questions
Does the GLO light whiten teeth by itself?
The whitening gel supplies the peroxide; the device is used with that gel as directed.
Can I use it with sensitive teeth?
Sensitivity can affect the choice and schedule, so ask a dentist before starting.
