When it comes to teeth whitening kits one of the biggest pros is that it’s cheap and that’s one of the main reasons why so many people are interested in using them. Going to a dentist to get your teeth whitening done is going to come at a minimum cost of $300-$1, 000+ (yes, it can be very costly). Most people are going to end up whitening at least 2x a year so going to a dentist is not a feasible option if you are on a tight budget.
But I cannot go on without saying that there is one advantage of using a dentist as opposed to using a teeth whitening kit and that’s simply because dentist are allowed to use higher amounts of hydrogen peroxide to whiten your teeth. Teeth whitening kits are usually limited to about 12%-16% hydrogen peroxide were as dentist can use up to percentages like 40%+. That in my honest opinion is the only benefit to using a dentist over a teeth whitening kit.
There happens to be one caveat and that’s this, some suggest that by using higher amounts of hydrogen peroxide you subject yourself to weakening not only your enamel but your overall teeth. Some doctors might give you what you want which is super white teeth but as you know this all comes at a cost later on. I recommend everyone at least try using a reputable whitening kit before going to a dentist so you can save yourself hundreds if not thousands of dollars.
Another thing you might want to take into consideration is that fact that in Europe you cannot purchase whitening kits with hydrogen peroxide. You can only purchase kits with carbamide peroxide, so that means that if you want to get your teeth whitening done your only chose would be to go to a dentist. Carbamide peroxide is only 1/3rd as effective as hydrogen peroxide and that means you would need 3x as much just to get the same results. Now the reason I brought this up is if you plan on staying anywhere in Europe for an extended period of time and you are from the US then it would make sense to purchase a whitening kit while you’re in the states. So if you’re a person who travels a lot for an extended period of time, a whitening kit can be somewhat of a savior.So at the end of the day you really need to evaluate your situation as well as what type of results you’re trying to get.
