  • This stuff is great, it makes my mouth feel great (fresh, clean, and tingley) everytime I brush. It seems to lighten slightly more than other toothpastes, but the tingle and feel of your mouth are much better than any other toothpaste I've ever tried. None of the other soda and peroxide pastes leave the same tingle, and its no more expensive than any other branded tube.

    I remember reading a newspaper article a while ago on the effectiveness of teeth whitening products.

The one product that they did recommend were crest white strips which you stick on and leave on.

      You're right. I remember when these first came to market, my dad, who is a dentist and performs teeth whitening procedures (among other things, of course), was actually worried because these OTC products whitened teeth almost as well as he did, but for a tiny, tiny fraction of the price. I think you only need to wear them twice a day, for half an hour each time, and over a few weeks your teeth will turn several shades whiter.

    stop drinking coffee, pepsi, and coca-cola, and your teeth will whiten on their own.

    the problem is that most people don't want to get rid of the things in their lives that cause problems, and elect to fix the effects rather than the problem itself.

    stop drinking and eating things that stain your teeth, and they won't be yellow anymore. simple as that.

      Also stop drinking red wine, grape juice, and eating tomatoes and chocolate. Oh, and stop getting older too, as your teeth become more porous.

      In my opinion, the thing to do is to stop thinking of yellowing teeth as a "problem" that needs to be fixed. It's natural.

      But if you are unduly influenced by Hollywood or all the Photoshopped magazine pictures, the thing to do is go to the dentist and get the real thing--a custom moulded tooth tray and whitening gel. My wife does this. There's a bit more upfront cost, but it works far better than the over-the-counter stuff, which won't get between your teeth.

      • Maybe its just me, but I find that certain foods do promote discolouration of the teeth. And you can avoid them.

        Avoid smokes, coffee and tea. Increase your intake of calcium. Brush your teeth properly.
        • Even with all that, some people at least will still get pretty heavy discoleration. I don't drink soda, coffee or tea. I only eat snackfoods at most once or twice per month. I do get 100% of my RDA of calcium, floss once a day, use mouthwash and brush after two meals a day, and rince my mouth out with water after lunch. Doing all that since my mid teens, I've still wound up with yellowed teeth at 24.
      • Speaking of between the teeth. Whoa, when you lose a tooth and get a chance to see what's between those suckers, it makes a little yellow on the outsides seem quite irrelevant.
        I've lost about three so far to root canals. Two broken as a youngster and one rotted out from general deterioration as I started getting older.
        Seeing what was between those puppies when one came out terrified me. I floss daily and brush plenty of times, but that doesn't matter. It's scarry.

    Alright, I can speak on this with a good degree of authority, even though I am not a dentist.

    First off - the toothpastes are no good. As someone already mentioned, they don't keep the peroxide close to your teeth long enough. Equally crappy are those paint-on peroxides.

    White Strips are great, but they don't whiten all of your teeth, so you're left with a white section on otherwise dingy teeth. Plus it's relatively expensive for the results you get.

    If you really want to whiten your teeth... you really should go see a dentist. You need to go regularly to make sure you don't have teeth that are rotting from the inside out. ...but I'm going to assume that you don't want to go to the dentist because they can be very expensive. Assuming that your teeth are in relatively good shape, but you drink a lot of coffee or what have you, your best bet is to search Google for a company offering both carbamide peroxide gel in syringes and CUSTOM-fit trays.

    Here's the drill - You get a kit with a few syringes filled the carbamide peroxide gel, two trays, a lump of putty, and a pre-paid envelope. You take the putty, mash it into a tray and make an impression of your teeth. Take the tray, drop it into the envelope and send it to the company. Several weeks later, they send you custom-fit trays. Put some gel in the NEW tray and put the tray in your mouth for 15-30 minutes a day for a week or two. Several days later, bam... white teeth!

      White strips are 'great' but they don't whiten all your teeth and they don't last. They're all 4/6/8% of some type of peroxide whitening agent and do not leave a lasting change. The kit that's being talked about above, is more like 18/22% and it will permanently change your smile in about 2 weeks. They suck b/c the stuff tastes kinda funky and you have to do it an hour each day, but the only possible side affect is sensitive teeth, which will go away if you stop using it.

      Once again, don't use those shitty whitening strips. they'll only help if you keep using them, which is great for the company that's selling. Go make one big spend and have a permanently whiter smile.

      I don't know if these still exist, but when I was a youth, they had these tooth guard things to put in your mouth when doing sports. First you boil some water, then drop this thing into it. When it's hold and melty, you put it in your mouth and bite down. It forms to your teeth and stays that way when it cools. This would save you the postage and time of mailing such a thing out.

      • They're nowhere NEAR the quality of custom-fit trays. The custom tray requires much less gel, and since it's closer to your teeth, less is wasted in the actual process as well.

      That's where you're wrong. I happen to be a world renowned dentist and specialise in the whitening of grubby teeth. The solution is as follows:

      1. You can't whiten you're teeth completely while there still in you're mouth - either have a dentist remove them, or if that is too expensive, remove them yourself. A pair of pliars will do the trick.
      2. You need to dissolve the grime, so leave them to soak for two weeks in a cup of concentrated sulphuric acid. You can order this from a chemical supplier, but your local garage will probably have some in supply.
      3. Remove the teeth from the acid, remebering to rinse well in distilled water.
      4. Now simply replace you teeth in your mouth used the glue of your choice. I recommend araldite. A strip of gaffer/duct tape can help to hold them in until the glue sets.

    Is the Crest's night time whiting stuff. You paint your teeth with it before you go to bed, and then brush it off in the morning. I recently used it before a wedding, and lots of people noticed my teeth were much whiter. I've also read some reviews that rated it above the others. It's a two week treatment, and you have to get used to sleeping with it on, but it works really really well.
    • I always found that Tipp-ex does a much 'whiter' job (closer to #000000) and can be bought in bulk from your local Office World.

      Less confrontational too, the checkout dollie will never know that you want it for your teeth so you can avoid talking your problems out with someone! woohoo, get back to your D&D quicker!
    • I agree fully about the night time gel. It's easy to apply and it coats your teeth for the entire night (although the effects lose potency after an hour or so, still, no harm). The key with all treatments is contact time. I used the night time gel from Crest for 2 and a half weeks and my teeth were sparkling white. It also helped reguvinate my somewhat haphazard brushing schedule. (I admit it. I don't brush everyday. I'm lazy.)

    I'm told that when it's officially launched Whitetooth will feature full backwards compatability with Bluetooth. Whitetooth features higher bandwith and increased range.

    I recently feild tested Bluetooth and Whitetooth in a few clubs and bars. Whitetooth fared better client responsiveness than Bluetooth or even the ubiquitous Yellowtooth. Clients which were signaled with the Whitetooth "grin" responded far more frequently than when presented with the Bluetooth "grin". The experimental Yellowtooth would often cause a total loss of communications with client devices in the vacinity.

    I would say that Whitetooth has a much brighter future than Bluetooth from these informal feild tests. I personally would avoid use of Yellowtooth until it gets cleaned up. If you don't have a Whitetooth vendor in your particular market, Bluetooth is still a good solution...

    As a dentist, first of all, I cannot recommend anything for a specific situation without actually seeing the situation myself. There are different reasons why teeth are yellow, and different ways of whitening as well. As mentioned by many others, get a dentist to have a look at the situation first.

    For some more general information about bleaching products: They are all peroxide-based, usually carbamide peroxide, which breaks down into hydrogen peroxide upon use. There are various ways of delivery. The over-the-counter methods such as the strips or paint-on system are lower in concentration than what you would find in a dentist-provided system, but basically the same thing. If you see a dentist, you can either have a home bleaching system made up for you, or have in-office bleaching done. The take-home system entails wearing a custom-made tray carrying the bleaching gel overnight. In-office bleaching uses quite a high concentration of peroxide, applied over a short period of time. Which one you pick depends on how much hassle you want, and costs will vary.

    How well does it work? Generally, there will be some whitening, but how much depends on the patient. Smoking, coffee, and foods that stain are absolute no-no's, especially right when you're doing the bleaching, since the teeth at that point can very easily pick stains back up. 'Clinically proven' is a phrase I absolutely hate. To me, it's just a marketing phrase, and says nothing about the amount or quality of research that has been done on a particular product.

    Last of all, there can be side effects from bleaching. Many people have reported sensitivity (hot and cold) after they've done it; It goes away for some. Also, I don't know of any long-term studies on whether the teeth are damaged in any way, or more susceptible to decay/etc., so that question is still up in the air.

    Personally, I do bleaching for patients on occasion, but I don't really push it, due to concern about side effects. Plus, I find the resulting look can be unnatural compared to how natural teeth are supposed to look.

    You basically have three options:

    1. Buying somethng off shelf

    These most of the times do not work. They are too weak, and they wash off too easily. If they have mouth guards, they are cheap ones that don't fit well.

    The advantage is that if you have sensitive teeth this is the best option. And it's the cheapest.

    Cost: $10-$40

    2. Using something like BriteSmile or.. (whatever other names are.. Zoom?)

    These work best. You sit in a chair, you watch a movie while an assistant props your mouth open and applies some paste. Then, they shine a light on the paste for an hour. You walk out with about 7 shades whiter.

    Cost: about $500.
    Advantages: fast! You can do it over lunch hour. Good results.

    3. Dentist at-home whitening

    Dentist gives you some syringes and a mouthguard. You add a little liquid to the mouthguard and wear them anywhere from 20 mins to overnight.

    Cost: about $300 initial (mouth guard is expensive), plus about $45 to resupply syringes periodically. Can buy them much cheaper off the internet (same big brands)

    Advantages: cheaper than britesmile, works much better than the off-the-shelf ones. Good results.
    Disadvantages: expensive, most sensitivity issues (especially with 20% concentrations)

    So, don't waste your money on off the shelf ones. Also, these things don't work on everything. If your teeth are gray because some medicine you took, you may need caps instead of bleaching. A dentist can tell you best.

    • As tea and coffee are the most powerful tooth stainers, how about neutralizing the staining ingredients first before they can get into your mouth by adding a de-colorizer like activated charcoal and a pinch of baking soda to your tea and coffee?

Also as a side benefit, they glow brightly under black light, so when I goto a funky bar-- I got the brightest teeth. Don't bleach them, smile proudly anyway, screw marketing. Please brush however, noone likes bad breath. P.S. Slashdot is not a place for any kind of real advice.
  • Just to put my oar in when I was last at my dentist there was a note up that they were no longer able to offer teeth whitening treatment due to EU laws.

    A quick search showed that as it was a cosmetic treatment the current laws restrict the concentration of hydrogen peroxide to 0.1%. Home kits apparently have about 3.6% and some treatments performed by dentists have up to 38%.

    The law is being an ass, but this should come as a surprise.

      When I read about the in-office systems at 38%, all I could do was say "No. No no no no no no no no no."

      3%, sure. 6%, maybe. But 38%? WTF d00d? Doctor, are you farking nuts? H202 is nasty stuff, crap, that's almost halfway to rocket fuel, and it's not something that

    Screw the over-the-counter stuff. Get your hazmat permit and go straight to the rocket-fuel supply store. Some of that hypergolic pure hydrogen peroxide will blow you away with whiteness! Guaranteed results with the first application!

    Warning: be very careful to not spill product during application. All surfaces, including the countertop, the cabinet, and likely the walls and foundation of your house may incur noticable damage. Perhaps the housing association won't notice the new windows...but you can't be too careful!
  • Why whiten when you can get Mr. Bling [mrbling.com] instead?

    Sure, it's a little more expensive, but think of all the fine honeys you'll get. You won't even have to get em drunk first, which can add up to substantially lower total cost of ownership.

  • I did a one our whitening treatment to my teeth and it produced dramatic results. The treatment was similar to "Brite Smile" but it was equipment from rembrandt instead. Here is a before/after picture. A2 was the color of my front teeth, A3 was the color of my canines

    You can get your teeth this much whiter with other methods, but it will also take a much longer time. Over the counter stop doesnt work very well at all, no matter what it is.

  • There was a really good Slate article on that very topic last year: http://slate.msn.com/id/2063524/ [msn.com]
  • Works slowly, but it works. And, it tastes a *lot* better than the other whitening toothpastes I've tried (Colgate, Crest, Arm & Hammer).
  • I've tried the crest whitening strips....(~$30) didn't work so well. I tried the cheap goo in the mouth peice (~$15 - forgot the maker)....not so good. I then tried the rembrandt goo in the mouth piece (~$35). This stuff works pretty well on coffee and tobacco stains. Just one man's opinion.
  • These both work, and work fairly quickly.

    However, the Whitenening Strips made my teeth ache if I used them for two days in a row. Had to switch to a one-day-on, two-days-off rotation.

    The Whiteneing Gel works ok, but you have to let it dry on your teeth without you tongue or lips touching your teeth (takes about two minutes). That was a real pain.

    I also tried another one that had used a gel and a tooth mold. That one didn't work too well, and it really made me salivate, which made a mess. Stopped usin

    While I'm not a dentist, I am a Dental Technicican who works for a dentist, and read the trades arround the office; so any opinions should be considered as questions for your licensed dental health providers.
    1. Clinical Proof = A sample of patients, selected by the manufacter to be highly motivated to comply with treatment protocols, and to have stains that the product are most effective against, have achieved a statisticaly significant whitening. The tester are dentists of course, and publish in peer reviewed journals, so they of course use a professional level of ethics; but because the work is funded by a vendor, results that are complimentary to the vendor tend to get submitted to the publisher, results that arn't tend to get forgotten,
    2. The amount of whitening is usualy poorly defined as a "shade" rather than well defined as in "Patient presented with shade A3.5 on the Vita Lumin(Tm) vacuum shade guide(an industry standard shade guide) and achieve shade A2 apon completetion of treatment".
    3. FDA approval for Dental products are not as riggerous as for Medical Products. In fact materials that are FDA regulated are not regulated by OSHA,alowing dental personnel to be exposed to chemicals that would not be allowed in any other work places.
    4. Teeth have two types of stain,
      1. external or extrinsic this is a staining of the bio-film, Plaque and tartar.
      2. internal or intrinstic staining of the actual tooth enamal such as coffee/tea/tobaco or even deeper levels as in tetracycline stains.

    5. All tooth whitening products work by oxygen bleaching, which is released from peroxide ions, either hydrogen peroxide (weaker) or from carboxamides (stronger). Additionaly the oxygen tends to kill or inhibit anaerobic organisms which are more likely to be pathogenic and odor causing.

    so I would recommend
    1. a professional teeth cleaning at your dentist's office or a local
      dental hygiene school.
    2. Using dent-mat's "Dazzling White" tooth paste kit,(low abrasion) or at least a bicarbonate of soda/hydrogen peroxide tooth paste and J&J's whitening dental floss for any remaining between teeth stains (abrasive).
    3. an Over The Counter toothe whitening product.

    don't get too carried away with the whitening, adults don't look natural with milk-white teeth, and teeth that are too white can make matching shades for restorative work immpossible. As for effectiveness I'd say that if the crest products were not effective, then the dental
    community would not be so royaly pissed off at them for marketing direct to the public, instead of through the dentists. In offfice or dentist supplied take home kits do tend to work faster.

  • Talk to your dentist. They can do all sorts of things in addition to the products you see advertised.

    Some dentists can get the Crest white strips in a much stronger version and I think more for the money.

    All in all talk to your dentist. The whitening strips work (not perfect but results are good) even for those who have yellow teeth by nature/accident (thanks to those drugs babies are no longer given).
  • Crest WhiteStrips are available in two forms. There is the kind that you can only get at the dentist, and then the kind you can get over the counter in many drugstores and groceries.

    The OTC version is much more dilute, and costs nearly the same as the dentist version.

    You are better off going to the dentist and getting those - which are $60 and work - then instead going to the store and buying them for $40 and having them not work.
  • While all tooth paste is mildly abrasive, the whitening ones are more abbrasive. You are not supposed to use whitening tooth pastes all the time. Eventually, you'll wear down your enamel.

    Remember the key to life: everything in moderation.

  • I have noticed that my herpes outbreaks are getting more nasty than usual. My genital warts are flaring up as well. What does the typical slashdot geek do to treat their symptoms? I've heard various TV and radio ads for products that claim to help, but before I shell out the $50 for the product, I'd like to hear how well it works. What are your thoughts?

  • Does use of the phrase 'clinically proven' require anything like FDA approval?

    I'm not a dentist, but my Dad is. The upshot is this: look on the packaging. On the front you're looking for a little logo that says:

    A D A

    On the back, it should have a little blurb that says something like:

    "[This product] has been shown to be an effective [product for a specific purpose] that can be of significant value when used as directed in conjunction with [other steps] in a
