Hi Dr. Nejad, Should you brush with toothpaste before putting in trays? I've read that it's better to brush/floss with just water before whitening (and brush with toothpaste after whitening). I was wondering if that has any real impact on whitening effectiveness. Thanks for putting these resources online and answering questions!
I appreciate you are still checking and answering questions even after 2years. As you know h2o2is very reactive, I have been told by other dentists the h2o2 is done reacting, has done all the stain removal / whitening that it will ever do after about 15/20 min. Another way of saying it is, 90% of the work is done in 15/20min. Empirically I have put a drop of various %'s of h2oh2 on various hard surfaces and it does stop bubbling after 15/20min. Your thoughts? This might explain why the in-office procedure is to replace the gel atthe 15min mark on 30 min whitenings and at 20min intervals on the 60min whitenings. ?? I don' tthink the "gel" medium plays a roll in any efficacy, just easier to apply, liquid h2o2 is easier to spill and larger liability at 45% per se.
Carbamide peroxide reacts to form Hydrogen peroxide slowly. It is active for up to 10 hours. Its a slow release mechanism of H2O2 and that is what I use and recommend.
Thank you for the information! I have my teeth mould, just waiting for the gel to arrive. I have 10ml of 35% CP, what times would you recommend please?
Thank you so much for this video, I was wondering is 35% carbamide peroxide safe for teeth, or can it cause permanent damage? And how many hours would you recommend as safe use, and for how many days?
You can use that overnight but only if you have done 10% overnight and tolerated it well. If you don't have 10% try 3-4 hours and if you tolerate it well, then add a few more hours overnight and see how it goes. Some people can tolerate 20% carbamide peroxide overnight but I don't recommend long-term use with 20%.
Thank you for the informative video! The upper tray i received doesnt quite reach the gumline of a lot of the teeth. Will this affect anything apart from having less of a seal? Am I correct in saying that the solution doesnt need to touch the entire tooth but instead gets absorbed into the tooth? I dont have any issue with the gel not staying in the tray, just curious if this will affect results
Thank u so much and I like how active u r by answering people's questions May I ask u if it is necessary to get a day off? Cuz my dentist told me to use it daily until I see the results And how long does it last?
You can go continuously with the gels I recommend but i recommend starting slow to see if you develop sensitivity. If you don’t and you are using a lower gel concentration, then it’s okay 👍🏼
Hi Dr. Matt, thank you for this informative video. I got 35% carbamide peroxide, is it safe to use and can it damage teeth enamel, and for how long would you recommend using it if it’s safe. And the whitening trays do not cover all of my teeth, there’s a bit at the top that’s not covered by it, can that cause a problem or can i use it still?
Hi, Great video! I ibought the white dental care novon teeth whitening product. The active ingredient is 10% carbamide peroxide. I was wondering if this product is safe to use after the expiration date? It expired at the start of this year? If I use it it won't damage the surface of my teeth would it? It is more likely that it will not be effective in whitening my teeth? The product in the syringes is still clear and has been stored properly since purchase.
Ive just started on custom trays with the 10% gel, and have been told to wear for 1 hour per day for 14 days. I havent experienced any sensitivity. Would you recommend upping the wear time? Is 1 hour enough?
Hi Matt very informative thank you. I’ve got custom trays using 6% peroxide hour at a time. I’ve read elsewhere that once I remove the trays I can clean them with a toothbrush and water (no toothpaste)? I notice that’s different to your advice in this video though
I made a mess of my first day, not enough gel as I didn't watch a video like this, the gel is just sitting in the indentations. Gel is not spread at all, I took one off and topped it up, but it was moist and now watered down. Lesson learned: Day 2 will be better. I just hope I don't wake up with white dots on my teeth 😅 Thanks for the tutorial. Gave you a sub good sir.
Doctor, I messed up my whitening tray. Can’t afford to replace it atm. Can I use the whitening gel directly on my teeth? Much appreciate for the feedback if possible 🤲🏾
I've been using a 10% gel for quite some time now. I saw a significant change but I still want my teeth to be whiter. So I was wondering if there was a certain amount of time that if I exceeded, it would damage my teeth.
If you are using 10% CP, it is safe to use for prolonged periods. Sometimes with patients that have tetracycline staining, they go over 6 months and there are case studies on that. I routinely have had patients use it for a few months. Best- MN
I usually do this overnight. There is no waiting period required if you did it during the day. Its really a myth that waiting will make the results better/longer lasting. I would just rinse out with water and go about my day.
Hi, i have a question. I have a stain line (not cavity, I asked the dentist) in one of my molars that I would like to lighten. Could I use some 6% hydrogen peroxide in that section of the tray to lighten it? I know you're only supposed to put the gel at the front but the stain really bothers me.
@@BiomimeticDentistry nope, not a crown it's my real tooth. The dentist said it's a stain line but he'd have to drill to get rid of it. I just thought maybe whitening would be easier. Thanks for your response!
You can try but generally they do not form a good seal around the gums to keep the gel in place. I would expect the results to be less effective and it could irritate the gums. The retainers have a different purpose than whitening trays.
I’ve just completed the 2 weeks 2 days ago, going in tomorrow for the in house session. I’ve noticed once I get my trays out in morning, teeth look whiter, but as the day goes by they turn back to the yellow shade. And now with the 2 days break my teeth look as before the 2 weeks. Does this mean it’s not working on my teeth? I followed instructions as per dentist recomandation. Any advices please?
@@BiomimeticDentistryhi doctor, I've got the 35% is it advisable to use? I've not started using it tho and it didn't come with a tray so how and where do I get the good tray? I'm so worried 😢
Your orthodontist doesn't know what he/she is talking about. The gel is not supposed to be swallowed, its meant to only touch teeth. The tray should keep the gel on the teeth and keep saliva away from the gel. Invisalign doesn't do any of it. Feel free to do whatever you want, but don't assume its safe to do it. Its worth knowing that peroxide makes free radicals and thats not something you want to have chronic exposure to systemtically. With the right tray, that is controlled.
Depends on why and its impossible to be sure so you should discuss with your dentist, but my guess is you are either using the wrong gel or have a poorly fitting tray. Best- MN
Sounds like your tray isn't forming a good seal and the gel is leaking out. The quality of your trays is critical, otherwise it is pointless to wear them overnight.
Well, I have no way to know what quality the specific dentist does. In principle, a quality made tray should have the best fit, and best seal. Drugstore kits are not comparable at all to this because they are not custom, or they involve some very basic customization options compared to trays that are specifically made for you and customized for best results. With that said, some dentist made trays are garbage so it really depends on the dentist. In terms of the actual whitening gel, there is a big difference because the ones a dentist can provide are prescription only. Sometimes you see them on amazon but they are gray market and not authorized for sale by the manufacturer. Over the counter or drugstore kits with lights are a gimmick. Drugstore whitening gels are not too effective. White strips kind of work but don't do a great job in between the teeth where you floss.
Hi Nicolas- well it depends. There are different materials, difference concentrations, etc. I would not go against what he says, but what I have described has been extensively studied and documented in the dental literature (Van Haywood).
@@BiomimeticDentistry I’m saying can I drink alcohol while using the trays. I got trays and it said to use for 7 days. I’m saying can I drink within these 7 days.
Hi Dr. Nejad,

I was wondering if that has any real impact on whitening effectiveness. Thanks for putting these resources online and answering questions!
Dr. Nejad, where do I get the trays? Am I able to go to my local dentist and get one? Im so confused, also where do I get the gel??
Hope it will work for me without any problems 🙃

Hi Dr. Matt,
Thanks for making the video. It's very informative. I got 16% carbamide peroxide, how many hour would you recommend for safe use?
You can use that overnight but only if you have done 10% overnight and tolerated it well. If you don't have 10% try 3-4 hours and if you tolerate it well, then add a few more hours overnight and see how it goes. Some people can tolerate 20% carbamide peroxide overnight but I don't recommend long-term use with 20%.
Realised that I’ve been putting the gel at the bottom of the tray rather than the top - will change this 😅

Am I correct in saying that the solution doesnt need to touch the entire tooth but instead gets absorbed into the tooth?

Usually should seal at the gumline, there are rare exceptions such as when you have significant recession with cervical root areas exposed. Best- MN

Hi Dr Matt Nejad,
Thanks for the video, may I ask does the gel works for whitening if I have bonded teeth? Many thanks!
Not really. Bondings do not whiten unless it’s surface stain and the gel can’t penetrate through the bondings to your tooth structure effectively.
Ive just started on custom trays with the 10% gel, and have been told to wear for 1 hour per day for 14 days.
I havent experienced any sensitivity.
Would you recommend upping the wear time?
Is 1 hour enough?
Wear them overnight
Hi Matt very informative thank you. I’ve got custom trays using 6% peroxide hour at a time. I’ve read elsewhere that once I remove the trays I can clean them with a toothbrush and water (no toothpaste)? I notice that’s different to your advice in this video though
There are different options. I try to avoid brushing them but that is ok. Be gentle on the tray and avoid scrubbing hard.
Do you keep the tray in place by lightly biting down? Or are you supposed to keep your upper and lower jaw separated at all times
If the tray fits well, it stays in place really well!
I made a mess of my first day, not enough gel as I didn't watch a video like this, the gel is just sitting in the indentations.
Gel is not spread at all, I took one off and topped it up, but it was moist and now watered down. Lesson learned: Day 2 will be better.

Thanks for the tutorial. Gave you a sub good sir.
don''t worry about dots. Just keep going and that will dissipate. Its pretty normal to happen. Thanks for the subcribe!
Do i have to dry my teeth befor i place custom tryes?
Hi dentist Matt nejad I want to know after applying ointment on teeth senseikin should I rinse it with water
Are they suitable for day wear?
Yes
I love your videos. Very explanatory 👌👌 thanks
My pleasure 😊
Doctor, I messed up my whitening tray.
Can’t afford to replace it atm. Can I use the whitening gel directly on my teeth?
Much appreciate for the feedback if possible 🤲🏾
No. You need to keep saliva off the tooth and prevent ingesting the material. Also bad for the gums and leads to irritation

What about the desensitisation gel? What's the best way to use it?
In the tray is best. Which one are you trying?
I have some gel I haven’t used and had it in my medicine cabinet for years, does it expire ?
It becomes less effective!
Hi Doc Matt,
Can i ask what the material is made of for the tray? as i'm in the uk and would like to get the same kind.
thanks for the video
soft eva 1.5mm
Hi Dr Matt, I have used the trays for like 8-10 times over the course of 3 weeks, but yet I don’t see a big improvement, what could i be doing wrong?
What gel? How good are trays? The seal is the deal. If its not a watertight seal, its not going to be too effective. The material is important too.
How long should I wait to eat or drink after application ?
I usually do this overnight. There is no waiting period required if you did it during the day. Its really a myth that waiting will make the results better/longer lasting. I would just rinse out with water and go about my day.
Can I put more whitening where I have white spots? I have only 2 white spots on my 2 front teeth.
Hi, i have a question. I have a stain line (not cavity, I asked the dentist) in one of my molars that I would like to lighten. Could I use some 6% hydrogen peroxide in that section of the tray to lighten it? I know you're only supposed to put the gel at the front but the stain really bothers me.
It could could work, but depends on what kind of stain. Are you sure its not the margin of a crown or restoration? It might also be abfraction.
@@BiomimeticDentistry nope, not a crown it's my real tooth. The dentist said it's a stain line but he'd have to drill to get rid of it. I just thought maybe whitening would be easier. Thanks for your response!
Can I use my regular retainers that I get after braces?
You can try but generally they do not form a good seal around the gums to keep the gel in place. I would expect the results to be less effective and it could irritate the gums. The retainers have a different purpose than whitening trays.
Can I use my custom made mouth guard as a whitening tray ? As my clear whitening tray is damaged ?
It depends on the material and design. Its definitely not the most effective and you have to avoid irritating the gums.

Does this mean it’s not working on my teeth? I followed instructions as per dentist recomandation. Any advices please?
Can you just leave the syringe as is or is there a specific step to close the syringe?
The syringes I use have a little cap. I would place the cap on so it doesn't leak out or at least put it in a bag until the syringe is done.
Can you whiten individual teeth with this method? My side teeth are more yellow compared to the front.
Yes, you can. Best-MN
Hi Dr. Matt, what's your opinion on Opalescence? That's the one I hear dentists recommending the most.
I like it a lot. It is what I use. 10% Carbamide peroxide by Ultradent.
@@BiomimeticDentistryhi doctor, I've got the 35% is it advisable to use? I've not started using it tho and it didn't come with a tray so how and where do I get the good tray?
I'm so worried 😢
could I apply the gel on my invisalign trays?
Yes it can work ! My orthodontist said there is no issue in doing it.
You can try. The seal isnt great on invisalign and its likely to irritate your gums so it is not advised.
Your orthodontist doesn't know what he/she is talking about. The gel is not supposed to be swallowed, its meant to only touch teeth.

mine says 35% carbamide peroxide, they didn't give me any directions just the needle thing
Where is gum protecting or no no necessary

My dentist instructed me for 9 days only and 1hour a day. Why such a low amount ? Would it be risky to do it overnight as suggested ?
Thanks Dr!
Hi Nicolas- well it depends. There are different materials, difference concentrations, etc. I would not go against what he says, but what I have described has been extensively studied and documented in the dental literature (Van Haywood).
What if you just put the Carbamide Peroxide on your toothbrush with the toothpaste? Will that work? I dont have a tray.
No. It needs to be in contact for an extended period and it irritates your soft tissue like gums and cheeks. Not effective or safe.
Can I drink alcohol
are you trolling me? You can do whatever you want. You can't drink anything with the trays in without messing it up.
@@BiomimeticDentistry I’m saying can I drink alcohol while using the trays. I got trays and it said to use for 7 days. I’m saying can I drink within these 7 days.
