Thank you so much. My dentists assistant has a deep accent and I really can’t understand her to well but I’m not the type of person to complain or even tell her that I don’t understand lol I just nod my head a thank her 😂 I had no idea what to do other than not using to much gel for every application. Very useful information ✌🏽🙏🏽🫡

Teeth whitening is a popular choice, but it's important to understand the process. Great video for breaking down the options. I wonder if you've compared long-term effects of different methods? Looking forward to more insights.

Thank you so much 🙏🏼 I could only find 35% CP syringes on Amazon

Hiya, I’ve just finished my Invisalign and now onto my retainers which I just wear at night. My dentist has provided me a free teeth whitening kit which he told me to use at just night time when I go sleep. But I’ve got a lot of saliva and keep wanting to spit. It’s my first time trying tonight. How long until I will see a difference?

I’m on day 7 of using a 22% Carbamide Peroxide whitening treatment. I apply it once or twice daily, leaving it on for 1.5 to 2 hours each time. I’ve noticed some results, but the whitening effect is only slightly noticeable. I want my teeth to be as white as my T-shirt. Can I continue this whitening process for at least 3 weeks without risking damage to my enamel?

Opalescence PF - 16% i just bought this one.
Can you tell me how long to wear it per day and how many days, i dont wont my teeth extra white just a little bit whiter?

[Kivota]

Thanks a lot for the detailed instructions! Just a quick question -- is it okay if I can taste the gel whilst using the trays? I'm using 6% hydrogen peroxide. I was careful not to overfill, just wondered if I should be concerned

How long is one syringe supposed to last?

Question... My dentist gave me 10% carbamide peroxide... But... Why? Why that particular dosage and not a highest amount? What is the determining factor and should I change to something stronger if I can tolerate the sensitivity?

[CarlJohnson]

Hi, super video ! I applied too much gel in the tray and whitened the top of my teeth as well as the back. Then I adjusted to apply it only in the front. Is that an issue?

Hello doctor, I apologize for my English. I have a question, I got 7 front crowns color bl3 (my doctor insisted that they were too white but I wanted that color anyway), turns out he was right 🙈, now they are cemented and I can’t do much about it, is it possible somehow to make them a little bit more yellow (to match at least a little my natural teeth)? I don’t care if it’s a temporary solution, I’m planning to redo everything in a couple of years anyway. Thank you very much!

Hi, I have 16% carbamide gel that’s 3 years old and was stored in a drawer (heat fluctuating between summer and winter). Is it still good to use or should I throw it away?

[TylerJenkins]

Will the gel damage dental retainers? I have clear/plastic retainers.

[Tobaccoforsure]

Can I use these trays to whiten my teeth if I have a missing tooth?

[claireism]

I'm using the teeth whitening tray. I've noticed it's making the tips of some teeth very white, and my teeth now look worse. Will this rectify itself, I've only done this for 3 days.

[gabriellasanchez]

What about 22% Carbonide peroxide? Is it same amount of time as the 20%

[mirapilates]

I accidentally wore my opalescence Carbonide Peroxide 10% for two months. Is this damaging to my teeth?

[larrybeagle]

I drink black iced coffee every day. My dentist office suggested drinking through a straw and then rinsing mouth after finishing a cup.

Hi Dr Rich, how long do you think should be fine for me to wear them as a course? I'm doing 22% CP, started out at about 30-60 mins a day because what the website of the gel recommended was 30, but now at about 1.5 hrs a day which seems to work better, slightly more sensitivity when eating afterwards but nothing unbearable. I do hope 1.5-2 hours will be fine though and not damage anything long term.

Now, here's what im really wondering - I've probably done about 10 days, a little different each day just to test, and I've gone a day without whitening twice in these 10 uses. What I'm wondering is, how long can I keep whitening? For instance, on the gel website they say 14 days, or uses, and 2 weeks/14 days is mostly what I hear, think I've heard 3 weeks once. But if I still wanted more whitening, since I've never done it before and I have/had smoker and coffee drinker stains, could I go a little longer, continue whitening each day for say 4 weeks in a row? If not, how long would I have to wait without the trays until its safe to whiten further? Please let me know your thoughts, thank you.
