How Long Does Teeth Whitening Last?

Last Updated: October 19th, 2022

We get it; teeth whitening is an investment of time and money, and you want the results to last as long as possible! Because everyone’s smile is unique, teeth whitening results differ for each person. How long teeth whitening lasts depends on a few factors.

Teeth Stains

Did you know that certain kinds of food and drink can stain your teeth? A few common culprits include coffee, tea, red wine, soda, bright curries, dark berries and beets. Even with regular brushing and flossing, these things create surface stains on teeth which dull tooth vibrance and color over time. This is normal and perhaps one reason why 37 million Americans used teeth whitening products in 2020, according to Statista data. Age, lifestyle and health factors also contribute to teeth discoloration.

How Teeth Stains Affect Teeth Whitening

Many adults have years of teeth stain build-up. The age and severity of the stains, plus your teeth’s natural shade of white, affect how long it takes to remove stains and the realistic degree of whitening. Getting completely white teeth isn’t always possible, but the good news is that even a few shades of whitening make a noticeable difference in a smile!

How to Get Whiter Teeth

At-home teeth whitening products are a great option for those looking to whiten their teeth on their terms and without the hefty cost of professional whitening treatment. Colgate teeth whitening products are easy to use and effective. Find out which product is best for you and your teeth whitening goals.

How Long Do At-Home Teeth Whitening Products Keep Your Teeth White?

Always use teeth whitening products as directed, and do not use them for longer than stated in the product’s instructions. Over-whitening can damage tooth enamel, making teeth more susceptible to surface stains and sensitivity. The last thing you want to do by whitening your teeth is risk more stains! You can extend the effects of teeth whitening between touch ups by maintaining your regular oral hygiene routine. Avoid dark-colored food and drinks if possible, and drink plenty of water to help rinse teeth of potential staining agents. See your dentist for regular cleanings and checkups, too!

How Long Does Professional Teeth Whitening Last?

Professional teeth whitening procedures differ from over-the-counter whitening products in a few ways. They require the supervision of a dental professional and use stronger whitening ingredients. Because professional whitening gels contain a higher concentration of whitening agents, results are usually faster, more dramatic and last longer than at-home products. However, professional whitening is often more expensive and time-consuming than over-the-counter teeth whitening. Talk to your dentist about which method is right for you.
