How Long Does Teeth Whitening Last?

Teeth whitening is one of the most common cosmetic procedures done in dentistry. And one of the most common questions that we get asked ALL the time is how long does teeth whitening last?  There are many options for tooth whitening and the length of time that visible results can vary as well. So read on…..


Let’s take a look at the types of whitening treatment available;

  • Whitening strips
  • Whitening toothpaste
  • Whitening pens
  • Whitening mouthwash
  • Whitening trays


Whitening strips: These are one of the easiest to whiten teeth.  Examples of whitening strips are Crest 3D White Glamorous white strips, Zimba Teeth whitening strips, etc. They contain very mild amounts of whitening agents so they are most effective for very mild discoloration or touch-up treatment. They are not effective when stains are very dark or long-standing. Relapse of the whitening is also relatively quicker.


Whitening toothpaste: These are used to easily and comfortably surface stains only. Examples of toothpaste that can be used are Tom’s of Maine Simply White Natural Toothpaste, Colgate Optic White Whitening Toothpaste, etc. However, most of them work only with mechanical abrasion  – they scrape the stain away physically and not chemically. Most of them are quite abrasive – so must be used with caution – especially if the enamel is very thin. For effective whitening of the tooth, brush the teeth at least twice a day and make sure you brush them well. They can be quite effective on nicotine, tea and coffee stains, however.


Whitening pens: These are small, thin, and portable plastic tubes that contain a whitening gel that helps to improve the teeth’ color by removing stains on the tooth. Unlike toothpaste, these whitening gels produce results quickly and brighten your smile but are only effective when used in small areas such as small nicks on the teeth where stains build up repeatedly.


Whitening mouthwash: This is one of the safest whitening treatments to use when considering teeth whitening because of the peroxide additive such as hydrogen peroxide or carbamide peroxide which is at a low concentration. This causes no harm to the teeth and oral tissues. It should be used 3-4 times a week for improvement, Whitening mouthwash with no alcohol in them is advised to be used as others that contain alcohol causes a drying effect and also lead to a dry mouth which might develop decay and cause tooth sensitivity. Examples are Colgate Optic White Whitening Mouthwash, Crest 3D White Brilliance Whitening Mouthwash, Solimo Whitening Mouthwash, Supersmile Whitening PreRinse, etc.


Whitening Trays: These are made of flexible material that fits over your teeth. They usually take more time than other whitening options. There are options for daytime wear for about thirty minutes twice a day and others meant for overnight wear for a few nights.  Examples are Opalescence and Zoom by Phillips. They are by far the MOST effective whitening methods and also last the longest since the whitening gel works undisturbed by the saliva which dilutes most whitening processes.
