Love the hands free ease of the take home unit! Y [SEP] I first started with the GLO teeth whitening system with my dentist. The system that you can get done at your dentist provides a stronger gel for a quicker and whiter result... So at the dentist i was only able to sit through three rounds... I think my experience was hindered by a lack of the dental technician using the system properly and keeping my gums protected properly. We had to stop after the third round (after an hour) due to a very painful jolt of burning like my nerves in my gum/tooth were being burned. So we could not continue. I plan on mentioning this at my next visit that i think my results could have been better. So these are things for you to mention if you’re starting at your dentist. The treatment and take home kit all together is around $600 so this is not something you want done wrong.<br /><br />As for the take home kit i really enjoy the packaging you get. The system comes in this sleek compact case with your mouth guard, light, lip balm, and ten gel packs. Be sure to charge your unit ASAP because it takes a few hours to fully charge. I really like that you can be hands free with no discomfort while using this system. The at home system has continued lifting my teeth and causing ZERO sensitivity (thank goodness!) i will update when i have finished a few more treatments.<br /><br />•picture is after on top and before on bottom. The top shows some imperfections because some spots got whiter than others. This has been getting better with the at home kit that i do a few times a week. Bottom isn’t bad but now my smile is very bright!<br /><br />•Second picture is the night of in office whitening in the light.  (Excuse my teeth I’m in the process of getting two implants after an illness destroyed my teeth :/)
