 Hello everybody Andrea here with dental L. So I've been a dental professional for about 17 years and I've done my fair share of whitening for 17 years. Currently I'm a mobile dental hygienist who has her own practice where I go to patients homes to clean their teeth, and also teeth whitening so let me do a very quick recap on the different types of teeth whitening. What works what doesn't and basically how things work so you'll have toothpaste so here are just what's a couple examples of toothpaste toothpaste work. If your teeth are already fairly white so they will actually keep things looking the whitest as possible because they help to remove remove surface stains. They do not make the teeth whiter they don't add bleach whitening products to the teeth, even if there's hydrogen peroxide in there, it's not going to actually change the shade. If you want to change the shade of your teeth which is usually the point, you do need a professional treatment but there's different types. There are different types of professional whitening treatment so the first one is where your dental hygienist will professionally apply it to your teeth so the system that I use, it takes one hour, and patients can go up to five shades lighter sometimes more depending on their current shade, but it works right away. We use a higher strength peroxide of carbamide peroxide and hydrogen peroxide it is not safe to be used at home, because it can burn the gums which is why it needs to be applied by a dental professional or a teeth whitening technician, but there's another professional type and that is something like this, which is a take home kit. So what this kit comes with as an example is it comes with a tray with a light. It includes whitening pens so you actually brush on the peroxide on the teeth. If you put the tray in the mouth for about 15 minutes to half an hour every day, you will go up to five shades lighter over three, five, seven days maybe 10 days if you apply it every day over that amount of time depending on your current shade will depend on for how many days you will need to apply this for to actually see the results you want so notice the differences here. So just quickly toothpaste could be anywhere from $10 to $40 or more. This home kit could be about 120 150 depending to have teeth whitening professionally applied could be 200 to 500 it really depends on where you are going. So I hope that helps kind of go over the different types but just remember, toothpaste are good if your teeth are already white you will get a nice. It kind of prevents the stain from sticking to the teeth quicker, especially if you're a coffee drinker wine drinker smoker that kind of thing, but to actually lighten the shade itself to lighten the enamel. You need a professional treatment by your dental professional or teeth whitening technician or a take home kit such as this one. I hope that helped you guys let me know if any questions and I'll see you guys in the next video.
