It has been proven the lights work with the jell. let me guess Red light therapy is also just a myth

[@BiomimeticDentistry]

Really? Oh wow thanks for clarifying. I guess all the papers I have compiled in my library are wrong. In the world of science, when multiple studies show contradicting information, it's safe to say the results are NOT proven. Read the article below, it is one of many papers that shows it is not effective. Furthermore, a few studies that show success have flawed experimental designs. Lastly, feel free to use the lights. A quick google search will show you how many people are not happy with the results. www.ncbi.nlm.nih.gov/pmc/articles/PMC4178330/

[@joseluismunoz470]

Wow this was great. All the other videos I watched on KZbin give me the bs about the light during professional whitening. Ima see if my dentist tries to sell me the same nonsense.

[@BiomimeticDentistry]

=) - The studies are all out there, people just need to read them. All the best studies on this topic were with 10% Carbamide peroxide without a light.

[@Sun.n.Flowers]

Same. I was just looking at the SNOW company and *most* of the reviews were 5 stars. The electric toothbrush is on sale, well, all their products are on sale, but if the light doesn't do anything, why get it?

[@Damned616]

@@Sun.n.Flowers Because people will buy it because they've seen whitening ads that show people using them.

[@nicholas_obert]

Regarding the "light-activated" peroxide at 2:13, peroxides are quite unstable molecules and exposure to radiation will degrade the peroxide (turn it into water and oxygen in case of hydrogen peroxide). The free oxygen atom may or may not react with your teeth. On the other hand, when the peroxide oxidizes directly your teeth, that oxygen atom will be used in the reaction that whitens your teeth. I haven't conduced research on this, but the theory tells me that using a light to break down peroxides will yield uncertain results, compared to not using a light.

[@Poniella81]

Wow so helpful. I’ve just bought a kit with loose trays to wear 20 mins per day for a few days. With a light, which I will ditch. The overnight version looks great.

[@AChickandaDuck]

So glad I saw this before buying a pricey kit with a light!

[@uknick]

Interesting. I just had the one hour laser treatment which along with the descale and polish made a massive improvement to my teeth whiteness. However, I also got the custom trays which are used for the following week. So I guess possibly best of both worlds??

[@BiomimeticDentistry]

Most of the instant change was likely the scale and polish to remove surface stains. My teeth get significantly whiter after a cleaning as well. One session with the light and gel is as effective as one session with just the gel.

[@Oldysrv]

As a prothodontics specialist i totally agree..I tell my pacients to save their money and do a custom tray for at home bleaching.Nice to see dr Nejad explaining this so beatifuly👍

[@BiomimeticDentistry]

Science! Love that you know. So much bad information out there. Best- MN

[@italotorres7000]

Excellent video Doc! One question, the protocol you use in your cases includes one day off from the whitening tray to diminish the chances of suffering from hypersensitivity, after 2 days wearing them overnight. My question is: how many cycles of on-and-off do you usually recommend the patient follows to achieve your treatment goals? For a period of 2-3 weeks? Thanks in advance!

[@BiomimeticDentistry]

Completely up to the patient and how much whitening they want to achieve. Typical is 2-4 weeks, but some times 2-3 months. Remember that results are progressive so its not 2-3 months until you see results, just gradual improvement over time.

[@italotorres7000]

Excellent video. Explanation and advice on proper products and procedures. Question . How do you think mixing toothpaste and hydrogen peroxide then put mixture into a tray would work?

Thank you! What would be the reason to mix the toothpaste? It would mess with the chemistry of the peroxide and make it less effective. I don't see any benefit of combining them! Best- MN

[@P1LL91]

Idk I just got the zoom whitening done for the first time and the results are miles ahead of any whitening strip I've used in the past. There's also conflicting studies shown on the light. Multiple sources claim the light triggers a reaction so there's probably a propriety blend besides the peroxide (given this isn't light activated) otherwise why would they use a light.

[@BiomimeticDentistry]

Carbide is long acting and has an active duration of up to 10 hours.

[@hellowill]

I got custom trays but it doesn't cover that great on the lower teeth, the gel seems to go to the tips of the teeth. For the upper teeth it works great. Any tips to use it better? Or should I complain to my dentist?

[@fireicevirgo]

how do we tell our dentists we don't want to do the treatment with the light (mine offers it with the light) and that we would prefer just skipping to at home custom trays?

[@BiomimeticDentistry]

Just ask if they make good custom whitening trays. Most make the trays but the quality varies a lot.

[@luv2travel2000]

You mentioned these are silicone custom trays (to sleep in overnight). If I am calling a dentist do I ask for a specific brand or just ask for an overnight silicone tray?

[@BiomimeticDentistry]

Ask for custom whitening trays. Some people make them better than others. Ive thought about making a service for this but it requires a high quality digital scan and screening from a dentist so I think it would be too difficult.

[@luv2travel2000]

Thank you for replying Dr. Nejad.

[@hillonthehills]

Why do my teeth go yellow few hrs after I remove the trays? I also finished my course of 2 weeks, and within 2 days my teeth look like before I started the treatment 2 weeks ago. I feel like enlighten is just a temporary optical illusion of glossy teeth…

[@tasty_mayo4454]

hey doc i have a question (might be a dumb one but oh well) so when you say to wear the trays for 2 nights then one night no, does that mean i have to wear them for two weeks while doing that cycle?

[@achillesjoe1447]

doc what is the recommended cycles when comes to whitening teeth? is 6 cycles and 8 minutes in between is okay?

[@BiomimeticDentistry]

I don't know what you mean. It depends on the gel but usually with the gels I would recommend, you don't do cycles. They are active for up to 10 hours so you would just wear it for 2 or more hours, but thats not for any gel so it depends on what you have. Unfortunately, it is not a universal application protocol.

What treatment does not damage the enamel

[@BiomimeticDentistry]

Carbamide Peroxide with custom trays does not damage enamel. Studies show it lowers the hardness in laboratory studies, but no clinical significance has been observed, and likely the hardness is restored with time. Its considered very safe.

[@nikpardu7716]

HinDoc. This made so much sense and unfortunately i fell for the light activating gel gimmick :/ i would order gladly these custom trays from you but i live in Germany. Do you have any recommendations or can you say what round a bout a normal price for these trays is? thank you!

[@sfiv1987]

This is true that the lights do nothing to help or boost the whitening process but there is evidence and studies show blue, red, and infrared lights help with gums disease

[@JamesAfshar_]

Thank you Doc!! Can i use my aligners as the trays? Currently using CANDID aligners…

[@BiomimeticDentistry]

Yes you can but results vary due to the material and design of the trays. They are for different purposes. I have seen patients use the trays effectively sometimes, but most of the time it is ineffective and leads to gum irritation. This is because aligner trays usually do not extend down to the gumline. Aligner trays are also hard and do not form a nice suction seal at the gumline. If you try it, do it for an hour or so max and ensure your gums are not turning white or getting irritated. I would personally recommend you wait until you are done with aligners and get a good set of bleaching trays. Recently, I helped Sprintray (a 3D printer company specialized in dentistry) started producing dental models with a perfect design to make excellent bleaching trays. That means you can ask your dentist about that, but they may not have the 3D printer.

[@oddity4650]

Does it put a layer on the teeth like hair dye, so it only covers the teeth or does it actually change the color of the teeth 🤔?

It actually changes the color. It oxidizes the chromatic component of tooth structure and ultimately lightens the shade, somewhat like bleaching does to color compounds in clothing.

Is this safe for sensitive teeth or will I regret it for the rest of my life? (Kinda like when I fried my hair with some bleach based hair product and it never grew back the same.) I don't need super bright white teeth, I just want to not wince every time I see myself in a video or picture. (So 2 or 3 shades lighter.) EDIT: By "this," I mean the custom tray Carbamide Peroxide treatment. Maybe I should do like 5%... I'm so worried, I'm always let down by people who are supposed to be professional. I can only trust myself to take care of myself. Maybe I would even start with like 3% and do it over night, then wait a couple weeks and repeat... hmm... we'll see.

[@BiomimeticDentistry]

Hey. This is the safest method available but there are conditions that definitely contribute to sensitivity like recession and abfraction. Everyone is different. We always manage to whiten and find a protocol that is tolerable when a patient is committed. I am Not aware of commercially available 3% or 5% carbamide peroxide teeth whitening gels. If you are really sensitive, there may be a reason.

[@ukidding]

I am brushing with baking soda, toothpaste and a teaspoon of peroxide once every 2 days or so for the last month. The jury is still out but i am getting a wee bit excited.

[@deanrobinson711]

If the peroxide is active for only 30 mins, why leave the peroxide on your teeth all night?

[@BiomimeticDentistry]

In the video I explain that Hydrogen peroxide is active for ~30 min, but Carbamide peroxide is active for ~10 hours. The time also varies with the concentration.

[@rAndyyyQ]

I have been using the whitening custom trays for 2 so days so far since I got it and I noticed white spots on my front teeth is that normal ?

[@BiomimeticDentistry]

Yes. Its a common stage of whitening that improves as you continue. If you stop it will also settle down.

I recommend 10% carbamide peroxide. Its a slow release formula.

[@AaaBbb-cq6kw]

Very informative and well made video, thank you. Is there a minimum or maximum number of hours for the overnight technique?

[@BiomimeticDentistry]

if you are using 10% Carbamide peroxide (CP), the gel is active for up to 10 hours. There is no maximum time to worry about, but it will stop working at some point which is fine. There is also no minimum per-se, but I would say 1-2 hours when using 10% CP.

While I can't comment on any whitening agents. I can comment on an awesome toothbrush. I purchased a Diamondclean 9700, over 4 years ago and it still is performing like the day I purchased it. I picked mine up on black friday at Kohls, but after checking the price, they are the same now that I paid on sale then- besides the little bit I got back in Kohls cash. I drink sodas and don't eat much candy and my teeth are in great shape; even my dental hygienist says that my build up is much less than other patients that she sees. If you do pick one up, make sure you purchase the black plastic replacements(when you eventually need them). The white ones, from like Costco, really aren't the best, nor do they have a proper fit. Lest I forget, my wife and I share the same base and use it every day. We charge the device, maybe once a week, we only do that because we feel that it needs a charge, not because it dies.

Show me your studies please. I have no reason for you to believe me or not, I am not selling you anything. What I am saying is fact. I don't know what is considered old to you but the studies are relevant because the gel and the light have not changed. This review study reviews 15 other studies with conflicting information and concludes no difference pubmed.ncbi.nlm.nih.gov/25298598/ When something works, you don't find this level of conflict. Furthermore, measuring the effectiveness immediately after the session creates an illusion of effectiveness because the teeth are dried and therefore whiter.
