Low concentration gel teeth whitening agents are the least effective form of teeth whitening agents on the market. These are often the ones that come in strip forms or have small trays that come in the package. They are also the one most commonly found in a local drug store.
Low concentration gels often come in at home kits and contain the smallest amount of the oxidizing agents. They are often found in the form of mouth guards or strips. They work by holding the oxidizing agent next to the teeth for as little as an hour and up to several hours. They often have to be repeated for a period of minimum of 5 days and can last up to 14 days. The results vary greatly for this product. Some may see slight results from low concentration gels in as little as a few days. Other may not see any results at all. It all depends on which product you use and how often you use it.
Low concentration gels are not the best way to go for teeth whitening. They are the least effective of all of the products on the market. They are proven to show the smallest amount of results. Also, they can take more time in trying to get results than they are often worth. Most would say they are not worth the money that is spent on them.
If you want to try teeth whitening products at home without the need for expensive dentist treatment, you should opt for high concentration teeth whitening kits for a better result.
