I use Crest Whitestrips. They work REALLY REALLY well but I buy mine from my dentist. They are a much higher strength than you can buy at the drug store. My dentist told me to quit wasting my money on that other stuff and try the professional strength Whitestrips, so I did. WOW! Made a huge difference and I am a coffee and soda drinker. The strips are pretty thin and do not ooze. Even if I do get some solution in my mouth due to saliva, it doesn't really have a taste at all. I put mine on in the shower where I am less likely to talk and move them around:) Sometimes they slip a bit, but they still cover the area they are supposed to, so no harm done. My dentist also told me NOT to use them on clean teeth otherwise they will definitely not stick. So, I put them on, take my shower, when my 30 minutes is up (and by the time I shower, dry, lotion it is time) I remove them and brush my teeth for the day. I love them! Good luck! Heidi

Thanks so much TREKaren and Carina for your replies. I actually found a site yesterday that has to do with rating the various whitening programs and the host of the site asked for any comments so I sent them my letter. Got a very nice reply back that said he'd been doing this for over 2 years and had never had a response like this. After doing further searches for any physical complaints I came up empty handed so guess this was a freak rare situation. She's getting better, but boy what a shock that must have been. Anyway, thanks for your help, and again if anyone else out there has had the same thing happen to them I'd love to hear about it. BarbB

I don't think the strips work good at all...I have some and don't use them. I bought bleach from my dentist and had a bleaching tray molded to fit my upper teeth. (Dentist said at the time that my bottom teeth don't really show so I wouldn't have to bleach them.) Anyway I wish I would have had a bottom tray made too. My teeth whitened about 4 shades...They look soooo much better. My daughters are really white. She uses the same thing I do. The bleach come in a syringe. 4 to a package for about 25.00. The expense was in the tray. I rebleach every now and then when I think about it. two or three months apart or more.. My dentist says his wife bleaches hers a couple times a week and she still has her teeth...lol patti

The first time I had the dentist make the trays and bought Opalescence from him also. I think it was about 200.00 maybe for the trays and whitener... then I found the Opalescence on Amazon for a fraction of the price the dentist sells it for. Once you whiten them you just use it occasionally to keep them white. It helps with the sensitivity if you don't leave them in for a long time and it's not really necessary, 30-45 minutes Is plenty of time. Opalescence comes in a couple different strengths so if you tend to have sensitive teeth buy the milder strength. Be sure to store the unused whitener in the refrigerator. Perhaps you could get a dentist to just make the trays and not buy the whitener from him, just order it off the internet. also remember, it just takes a drop of the whitener, don't just load the tray up, it would be a waste and could cause gum irritation. I squirt out a small amount on the bottom front part of each tooth in the tray, when you put the tray in the whitener will spread onto the surface of your teeth.
