Is this too unprofessional
Hello
Welcome to my channel
I am Dr. Teresa, a general dentist in Vancouver, Canada,
without further ado
Let's first look at the principle of teeth whitening
The HK actress Linda Chung shared her
at home teeth whitening method using charcoal powder
if you are interested in learning about charcoal use
you can check out that video
In that video, I mentioned that
the only ingredient that can whiten your teeth is hydrogen peroxide
when hydrogen peroxide penetrates enamel and enters dentin
it will break down the pigment molecules
change its chemical structure (double bond) from dark color to light color
this is a permanent change
it can actually change your teeth inherent color
However overtime,
there will be new pigment molecules
so teeth whitening is not once for all type of treatment
it needs to be maintained
The whitening result will depend on the concentration of the hydrogen peroxide
and its contact time with your teeth
the higher the concentration
the longer the contact time
you will achieve better whitening result
everyone's teeth are also different
so the whitening result varies
between different people
In the next video, I will talk about who is not a good candidate
for teeth whitening
In today's video, I will focus more on Crest whitening strip
So, is Crest whitening strip effective?
Yes
Crest whitening strip is essential a tape
with hydrogen peroxide in the glue
so they have the correct active ingredient
Anything that has hydrogen peroxide
will whiten your teeth
When we chose home whitening products,
there are 3 things to look for
Fist, What is the concentration of hydrogen peroxide?
The concentration
will vary depending on your location
Every country has different safety regulations
The most common rage is 6-10 % hydrogen peroxide for home whitening
For Professional whitening
you can reach to 30% or even 40%
In fact, there is something I dont like about crest strip
is that
it doesn't indicate hydrogen concentration anywhere
So first, you need to check the concentration
Second, you need to see
how is the hydrogen peroxide going to stay on your teeth
does it come in the form of gel?
whitening pen? or strip?
The application mode is important
we need to ensure our gum can be protected
For example, whitening mouth wash
or whitening pen can easily get hydrogen peroxide
onto your tongue and gum
though the hydrogen peroxide will be diluted by your saliva once it leaks out
the high concentration of hydrogen peroxide (or prolong use)
can still burn your gum or intra-oral tissues
so at least, the whitening strip
sticks on your teeth
and doesnt have hydrogen peroxide in liquid form
to leak to other places in your mouth
Third, we need to see if the application mode can prevent hydrogen peroxide from getting diluted by your saliva
just like whitening pen
or even some people will tell you to just rinse
with 3% over the counter liquid hydrogen peroxide
But the problem is
once the hydrogen is diluted by your saliva
concentration will decrease
then the whitening effect will decrease
So, based on these three points
I feel the Crest Strip is a good home whitening method
concentration is high enough
to be effective but it is still safe
it can also stick on your teeth
doesnt really touch your gum
and the plastic can prevent saliva from diluting it too quickly
I am going to share with you my VIP tip
So listen up, screen shot it and share with your friends
if you are using Crest strip
or any hydrogen peroxide containing whitening products
you can go buy Vitamin E oil
either in cuspules
or in a bottle of oil
apply the oil on your gum
Vitamin E can effectively reduce
inflammation of your gum
and protects it from getting injured
It is also an oil
so it can act like a barrier
When I was using Crest strip before
I always put Vitamin E oil on the gum first then applied the strip
I never experienced any gum discomfort from whitenig
So many people are wondering how to minimize teeth sensitivity from whitening products
I will recommend you to use Sensodyne toothpaste
at least 2 weeks prior, during treatment and 2 weeks after treatment
If your teeth are normally very sensitive
apply sensodyne toothpaste on your teeth
after you brush your teeth; spit and dont rinse
if you have these clear retainers
put on the toothpaste
then wear the retainer before going to bed
it will maintain the concentration of de-sensitizing ingredients and increase contact time
its like putting on anti-sensitivity mask on your teeth
also dont use whitening strip everyday
pick a mild one
wait for a couple days until you use the next strip
do not whitening your teeth too quickly
or use very high concentration
Check the recommended wear time on Crest whitening strip
some recommend 30 mins wear time
some recommend 60 min wear time. Do not exceed recommended time
hello welcome to my washroom
let me demonstrate how to properly use the strip
I havent whitened my teeth for a long time
because I am wearing Invisalign
Look at my teeth
they are getting yellow
have have lipstick stain
see those white chunks on my teeth?
Those are composite attachments (white buttons)
to allow the Invisalign trays to
grab on your teeth tighter
to move your teeth more effectively
Unfortunately, hydrogen peroxide cant penetrate composite
so you may get uneven whitening result, so I decided not to whitening my teeth for now
anyways, I still have some old whitening strips
that I bought before
The strips come in a box
there maybe 14 treatments or 20 treatments
It depends on which product
this one is the "Professional Effect"
lets open it
inside there is the strip
there is instruction on the packaging
the top long strip is for your top teeth
some people want to save cost
they will cut the strip in half
yeah sure . why not (may not stick as well though)
when you apply the strip
avoid your gum
place lower than the gum line
when you apply
hold the extra strip inward
wait for 30 mins or 60 mins
or whatever the recommended time is for your product
after the strip is on, use your nail to press strip inbetween teeth
So what is the proper order between brushing, flossing and strips?
First floss well to clean the plaque between your teeth
or go get a professional cleaning
to ensure there is no calculus between your teeth
it will help hydrogen peroxide to penetrate in between teeth better
and achieve a more even whitening result
so floss first
dont brush
dab off all the saliva on your teeth to ensure they are very dry
then use the strip
after you are done with the strip
remove it then go brush your teeth
and remember to use desensitizing toothpaste
2 weeks before, during and after treatment
some people say that they notice white spots appearing after they remove the strip
when have the strip on
your teeth become dry
because ideal
your saliva shouldnt touch your teeth
when teeth are very dry
your own white spots will become more obvious
overtime, when the saliva moisturizes the teeth
your white spots will become less apparent
There are two annoying things with the strip
if your teeth are not completely dry
it doesnt stick well
also,
remember to dab off saliva constantly,
otherwise you can taste the glue
doesnt have much taste, but the texture is not very pleasant
you also dont want to dilute
hydrogen peroxide
Okay reporter Teresa is done showing how to use whitening strip
now back to the anchor
let me summarize the pros and cons of Crest whitening strip
The advantage is its price
much cheaper than professional whitening
it is effective
and safe
you can have 1-3 shades improvement
but you want to change from ordinary yellow to super white
that is impossible with the strip
the strip is also convenient
easy to carry out to travel
easy to use as well
there are also many Crest whitening strip products
you can try it out and find one best suits your teeth
there are 10 different whitening strips for Crest
in my next video, I will tell you how to pick
the one best suits you
and talk about if the whitening LED light is a gem or gimmick
But what is the disadvantage of using Crest whitening strip?
Unfortunately
Crest whitening strip doesn't have any anti-sensitivity ingredients
in the whitening gel
if your teeth are crowded
the strip may not adapt very well
especially where the teeth overlap
or in between the teeth, it may still be abit yellow
Second, because its not customized
it can still touch your root and gum
if your teeth are sensitive
or have periodontal disease
or exposed dentin
you may experience severe sensitivity
if you belong to this group, please consult with your dentist
to see which whitening method suits you the best
you might need professional whitening
or customized whitening tray to whiten at home
so you can effectively protect the surrounding tissues
