After reading comments about people claiming they didn't have the same quality as the dentist's office, I asked my friend, a dental hygienist, to check them out out. They are exactly the same as the ones she gave me including packaging and all. She says they sell them for $15 a syringe because dental offices are always overpriced. If they burn your gums, you need to put less on the retainer, for example the smallest amount. You can also apply baking soda with a watery tip if it gets on your gums. Great suggestion and very effective!
