Dear Dr
I had my teeth whitened at my dentist and she used the reputible company Voco system on me. I was concerned because i wasnt aware that Hydrogen Peroxide was used which is an acid…my question is why do dentists use an acid to whiten teeth? Do your teeth reminilize? I thought enamel didnt heal and i found out that the PH used was 4 and this was in house for 20 mins is this bad? Im worried? Have i got a right to be?
Would appreciate your best advise thankyou for your time,
Dear Dentist
My question is regards to whitening � Is Hydrogen Peroxide bad for your teeth or whitening in general does it cause cavities if you used say 30% in house bleaching?
I am confused because it is a weak acid so why do we use it on whitening?
Does a high percent of Hydrogen Peroxide not cause cracks in teeth or make them matte/loose their shine?
How does whitening work? thank you for your time
Please can you answer the following please?
Is 27% Hydrogen Peroxide really harmful to the teeth and pulp? Can it cause craze lines or worsen them?
Would I feel 27% Hydrogen Peroxide if it spilled directly onto my gums or lip area?
(When my dentist was carrying out in chair I accidently dribbled some of my saliva on to my lips, would this harm my lips as it might have touched the peroxide then feel onto my lips?)
Also I heard that Hydrogen peroxide has the toxic hydroxyl radical and I am wondering if this can get into your blood stream via your pulp in your teeth and produce free radical damage in your mouth area and promote cancer cells.
I know I am looking in to this but I am really worried, I may look a bit of a hypochondriac but I read that Hydrogen Peroxide is a weak cancer promoter and a lot of people in my family have died due to cancer illness, I feel now I have had in surgery teeth whitening I have promoted a carcinogen cascade of free radical damage that will keep multiplying and I will get oral cancer from this.
Thank you for your time
Sorry if this sounds over the top, but please can you answer my questions, thank you
Dear Dentist
I had my teeth whitening in surgery and my dentist used 27% Hydrogen Peroxide. Since then I run my tongue over my teeth and they feel slightly rough. I ca also see abrasive brush and scratch marks on the enamel in light on my canines. And when I run my nail over them they feel lumpy. I never studied or felt my teeth like this before but could a high level peroxide potentially burn or change the texture of your enamel? I feel as if I have damaged the structure of my teeth?
Also does tooth whitening with high level peroxide permanently make the enamel more porous and prone to cavities?
Thank you for your time
