The Pros and Cons of Teeth Whitening Trays

Teeth whitening trays are one of the most commonly used at home options. Are they worth using? Let's consider the pros and cons first.

Most people want their teeth to look good when they smile and this typically means having teeth that are white and free of stains. While some people may naturally have whiter looking teeth, more often than not some assistance will be required and this can especially be the case as people grow older. An option for achieving a brighter smile is teeth whitening trays and there are a few pros and cons to using these.


Can be used at home

One of the major benefits of teeth whitening trays, whether store bought or from a dentist, is that they can be used at home. This means visits to the dentist to carry out the procedure are not required and most people will find this more convenient. It basically means that they can use the trays at a time that suits their usual daily schedule rather than having to take time out of this for a trip to a dental office. For the best results whitening trays for teeth typically need to be used on a few occasions over a period of time. This can be much easier to do at home and can be fitted into the usual oral care regime that is practiced on a daily basis.

Easy to Use

Teeth whitening trays are typically easy to insert and most people will be able to do this themselves. There are a couple of different options available with some including disposable one-use trays that are pre-filled with gel, and others including a re-usable tray that needs to be manually filled with gel before application. However, in either case the procedure of fitting this into the mouth is pretty straightforward, such that anyone should be capable of whitening their teeth using the tray.


The cost of using teeth whitening trays can be an advantage of choosing this method. This is especially so with regard to store-bought options which can be much more affordable than visiting a dentist to have your teeth whitened. Aquafresh White Trays, for example, are available at a number of retailers and is one of the more affordable options. It costs around $20 to $30 for a pack of 7 upper and 7 lower teeth trays. However, most store bought whitening tray kits are affordable to buy and this can be a positive benefit of using them.


One Size Fits All

One of the major problems with store-bought teeth whitening trays is that the trays are one-size-fits-all. This means they are designed to fit the average mouth and many people may find that they do not actually fit over all the teeth snugly. This can obviously have an effect on performance, since if the gel adequately covers some teeth but not others there will be a difference in the whiteness achieved. A tray that does not snugly fit the teeth may also allow the gel to get onto the gums and this may cause irritation for some. It is possible to get custom fitted trays produced by a dentist that are specifically shaped to the teeth of the wearer. However, this will obviously be a more expensive option to use.

Tray Filling and Cleaning Can Be Messy

While whitening trays for teeth are typically fairly easy to insert, if you are not careful it can be a messy process filling the tray for use. It is better to avoid getting the bleaching gel on skin or spilling it onto furniture and flooring, so it pays to take time when filling the tray. Also, unless you are using a disposable model, whitening trays for teeth need to be cleaned after use to keep them hygienic and prepare them for re-use. Many people can see this as a chore and going through the procedure of filling and then cleaning the whitening tray can be off-putting for many people.

For those considering the options for improving the look of their smile, teeth whitening trays are an option to consider. There are pros and cons to using this method, with some of these shown above. The advantages and disadvantages should be considered carefully before going ahead to make sure that the method is something you are comfortable with and happy to use.
