How Long Will Teeth Whitening Last?

Teeth whitening treatments allow you to feel better about the way you look with a relatively minimal amount of effort. The whitening procedure is fairly quick to perform and is normally cost-effective for any of our patients that wish to have it done.  Whiter teeth have a direct correlation with most people to a heightened self-esteem too so it’s important that once you whiten them, the results last for a while!

It’s important to understand that teeth whitening is not something that will last you forever and that stains will begin to return. Eating and drinking acidic things will slowly cause your whitened teeth to yellow over time, so it’s important to take the proper steps to extend that whiteness as long as possible.

Whether you decide to have your teeth whitened via in-office teeth whitening, or professionally fitted take-home trays, Dr. Phan will educate you on the entire process from start to finish. Following these steps will also ensure your whiter teeth remain that way for longer.

Avoid acidic foods & drinks

Teeth whitening works by removing stains from the surface of the teeth. This outer coating of the teeth is called your enamel. Whitening does not provide protection against future discoloration, so it’s important to avoid consuming things that will discolor them again. Foods that are high in acidity may also cause rough patches on your teeth to occur, which can cause patchy stains to occur and return at a faster rate.

In order to best delay the return of stains, try to avoid food and drinks such as:

  • Tea and coffee
  • High sugar colas and other dark sodas
  • Red wine
  • Dark or acidic fruit juices such as cranberry or pineapple
  • Acidic foods such as tomato sauce

Reduce effects of staining after over-indulging

It’s understandable that you can’t completely eliminate things from your diet which are bad for your teeth. Although something might be bad for your teeth, it doesn’t necessarily mean it’s bad for your health too! Things such as cranberry juice or red wine do actually have health benefits for you. Some of the steps you can use to reduce your exposure to things that may yellow your teeth are:

  • Drinking through a paper straw to reduce the amount of substance that contacts your teeth
  • Brushing your teeth after consuming acidic things to reduce the amount of exposure to them

Eliminate tobacco use

The use of tobacco causes cancer and other well-documented health problems. Although most are aware of this fact, tobacco use also causes severe yellowing and staining of your teeth. It can be detrimental to your oral health and should never be a part of your daily lifestyle as more and more nicotine substitutes enter the marketplace. Using tobacco after whitening your teeth could drastically reduce the duration your teeth actually remain white!

Regular check-ups

If you attempt to remain healthy and are conscious of your oral health, you can likely expect teeth whitening treatments to last you between one to three years. It is all dependent on how you take care of your teeth, which can reduce or extend this time frame.

Be sure to get the most out of your teeth whitening procedure by having Dr. Phuong Phan and our team at Kingstowne Dentistry check and clean your teeth every six months. This will ensure not only your teeth remain white for as long as possible, but also ensures proper oral hygiene as well.

    I was recently told my teeth were looking slightly yellow and ever since I started researching teeth whitening in Midwest City to help me with my problem. Fortunately for me, I came across your great article that is jam-packed with information. I really like how you mentioned whitening does not provide protection against future discoloration, so it’s important to avoid consuming things that will discolor them again. I am sure many of those like me can agree with this point to ensure the teeth whitening last longer. Thanks for this!

    I am glad that you mentioned that teeth whitening treatments can last one to three years. I am getting married in 3 months and would like to get a whitening treatment beforehand. It would be smart for me to consult with a dentist soon so I can get my smile ready for the big day!
