Can Hydrogen Peroxide harm my teeth?

Tuesday, May 31st, 2011
Q.

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

Has teeth whitening damaged my teeth?

Tuesday, May 31st, 2011
Q.

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

Does teeth whitening weaken or damage your teeth?

Monday, May 23rd, 2011
Q.

Hello Doctor
Does teeth whitening weaken or damage your teeth in any way and would you recommend it for any age? I am 53 and am considering having four porcelain crowns at the front but I would like my teeth whitened first and then have the new crowns match them. I am concerned that I may be damaging my teeth by having them whitened. And as my teeth aren’t naturally white does the whitening fade and if so how often would I need to have the treatment?
Thank you for your time

Can you whiten tetracycline stains?

Thursday, May 12th, 2011
Q.

i had Tetracycline for tonsilitis as a child, I hate my teeth, all my family have white teeth but me & also still have my tonsils-which at my age are still irritating. Which are the best option for healthy teeth wishing they were pearly-whites like rest of my familys’. I am embarrassed @ most first meetings with people especially if they meet my sister then I feel they are asking themselves why doesn’t she have nice white teeth?

Thursday, May 12th, 2011
Q.

Hello, I had eight porcelain veneers fiited five years ago, although I am very happy with the result of a lovely smile, I now wish that I had had the veneers made whiter than they are at present. Please could you tell me if it possible to have my present veneers cosmetically whitened without having to have new veneers? Also how long should I expect the veneers to last before the set will have to be replaced. My worry is also the longer that they are fitted, what is the possibility that my gums will change and that the veneers will , worst case sceniario fall off, arrgh!? Please could you help. Kind Reagrds,

Home teeth whitening kit has left my teeth blotchy. What could this be?

Thursday, May 12th, 2011
Q.

I recently purchased teeth whitening from my dentist. I had custom trays and was informed to bleach overnight. after a couple of days my normally even teeth became a bit whiter but much more uneven. I was away on business so called the dentist and they said to keep going and it should even out. But since I was not at home near my dentist i didn’t want it to get worse especially on my front teeth. My dentist suggested i continue on one back tooth and see what happens. So i continued on one tooth for about a week, but the uneveness did not go away so i did not continue with the bleaching. When I returned a week ago to show my dentist, and return the kit she said I was correct to stop and that she would call the company who provided the bleach. They said this can happen sometimes. In any case, she said there was nothing that could be done and to leave it and not use whitening toothpastes. I am now left with patchyness which I am very aware of and bother me and miss my normal teeth and regret starting this process. Will the bleeching eventually fade and go back to how my teeth were before or am I stuck with this uneveness? It has been four months since I stopped bleaching and I don’t see any fading of the patches that are whiter than the rest of my teeth. Can you please advise? Is there anything I can do without continuing to bleach b/c i am worried to continue as worried it will get worse. is there another treatment? My dentist thought it was more likely that this was something under my teeth that has come up (don’t know if it is calcium deposits) as a result of the bleaching than uneven bleaching b/c they were custom trays. Please help! Thanks
