Answers:
Definately! I've had 3 people within a 2 week time frame tell me how white my teeth were. I don't even use them daily let alone twice a day like you're supposed to. I use them maybe once a week or every other week because they are uncomfortable to wear even for 1/2 hr. So using them less often will stretch the "month" supply they come with. also, you may experience a slight uncomfortable sensation if you have sensitive teeth, but it goes away and is worth it. Check your Sunday paper, often there are $5 or $7 off coupons for them.Health Question & Answer
