How Long Does Teeth Whitening Last? 


One of the most common dental complaints amongst the average American is tooth discoloration. There are a million different factors that contribute to teeth staining. Some of the most common include frequent drinking of liquids like coffee, tea and red wine. Other foods like curry, red sauce and fruits are also common staining culprits. There are enough items that can stain your teeth out there that completely avoiding them isn’t really a feasible option. That’s why so many people turn to teeth whitening. 


There are many over-the-counter solutions to this from gels and whitening strips to lights that you shine in your mouth, there are a lot of options out there. However, the most effective way to whiten your teeth is to have it done professionally by a dentist. Unfortunately, teeth whitening certainly is not cheap and since it’s a cosmetic procedure it’s usually not covered by insurance. That leaves many people asking the same question: How long does teeth whitening last? 


Whitening your teeth is analogous to bleaching your white laundry. It works, but it isn’t permanent. Over time, more stains are going to build up and you’ll have to whiten your teeth again. However, the advantage of having your teeth professionally whitened is that the bleaching process lasts much longer than over-the-counter solutions. That’s because professional teeth bleaching actually attacks stains at the molecular level. 


Teeth whitening is effective at removing existing stains, but it won’t protect your teeth from new stains. That’s why many patients get their teeth whitened every few years. The most effective way of extending the time between whitening procedures is to avoid foods and drinks that are known to stain. 


It is worth noting that there is no health risk associated with stained teeth. The procedure is purely cosmetic, which is why many dental insurers don’t offer coverage. As a result, teeth whitening procedures can become costly. Be sure to do your research and take care of any dental issues that have health consequences first.
