How Long Does Professional Teeth Whitening Last?

Everyone loves a pearly white smile, but not all of us are born with one or will keep the one we are born with. Various foods, beverages, and even medications can cause teeth to yellow, gray, or turn other colors besides the desired bright white.


If this has happened to your teeth, you may be exploring your options for teeth whitening. One factor to consider is how long the results will last. If you want long-lasting, reliable results, professional teeth whitening is often the way to go.

Professional Teeth Whitening

It’s been proven that the most effective way to whiten your teeth is with a professional teeth whitening treatment done in a dentist’s office. The procedure can be performed several times until the desired results are achieved. The results of a professional teeth whitening treatment can last between one and three years—the longest offered by any teeth whitening treatment.


Many dentists also offer take-home teeth whitening treatments. Typically, you can use these treatments once a day for up to two weeks. Similar to the ones that are performed in their office, these results often last for about one year.

At-Home Teeth Whitening Kits

A variety of at-home dental teeth whitening kits are available for purchase without a prescription. While these kits might seem convenient, teeth whitening can take a lot longer with them, up to four to six weeks, and may not be as effective. Results can vary by each individual; however, with an at-home kit, you can expect the results of your treatment to last four to six months.

Frequently Asked Questions About Teeth Whitening

Should I Have My Teeth Cleaned Before or After Teeth Whitening?

Teeth whitening works best on clean teeth that are free of plaque and tartar. Routine dental cleanings are crucial for your health and will also ensure the best possible results for whitening. The good news is that if you are currently due for a cleaning, you can schedule the dental cleaning and the teeth whitening to follow on the same day. 

Does Teeth Whitening Hurt?

It’s common for teeth whitening to result in some sensitivity to the teeth and gums. Some individuals experience little to no sensitivity, while others may need to limit the strength and time of the bleaching to avoid discomfort. You can reduce sensitivity by discussing it with your dentist and always having the procedure performed by a licensed professional.


Your dentist may suggest a special toothpaste to use before and after teeth whitening, as well as only certain types of whitening. If you do have sensitivity after treatment, an OTC pain reliever can usually help to alleviate the symptoms.
