How are home teeth whitening kits different from in-office whitening?
Christopher Baer (Aurora, CO) on Jun 9, 2012
Yes they are. The difference is typically in the strength of the whitening agent and sometimes the whitening agent itself is different. There are two kinds of home whitening- the over the counter, store brands that are typically one size fits all strips that my give some people good results. The second kind which we offer in our office are custom fit trays that conform to your teeth. These trays hold the bleach up against the teeth and if well made, will help prevent the bleach from leaching out into your mouth. You typically use these trays for 1-2 hours every day for two- four weeks depending on the color you desire. There is often minimal tooth sensitivity and the results are great if you are consistent. This is also the best method if you have any areas of gum recession or sensitive teeth. The In-Office Whitening systems vary as well. Some are activated by a light or laser, while others are activated chemically by mixing two agents together. This type of tooth whitening typically uses stronger whitening agents and that is why we do it in to office, to prevent possible problems. It only takes about 90 minutes to complete. However, you may experience more sensitivity with this process, but it takes the least amount of time and the results are great!
