Having pearly white teeth is no longer considered a luxury but rather a necessity. Those with whiter teeth are more self-confident and generally feel better about their bodies. However, teeth whitening was for long considered a preserve for the wealthy. You would have to dig deep into your pockets to achieve brighter smiles due to the limited options.

Today, there are more than enough methods of whitening teeth, including some techniques that you can use at home. One of the most effective ways of whitening teeth is through whitening trays. These products are known to deliver results and, above all, are much more affordable than in-office whitening.

But what exactly are teeth whitening trays? What are some of their benefits and drawbacks over other methods? Let’s delve deeper and understand more about teeth whitening trays.

What Are Teeth Whitening Trays?

Teeth whitening (bleaching) trays are key players in DIY teeth whitening. They are products made from flexible, moldable material that fits on your teeth.

You can also get custom teeth whitening trays at the dentist’s or by the provider. Some of them can be easily purchased over the counter at your local dental store. You add a whitening gel or material to the trays before placing them over your teeth for a specified amount of time to make them whiter.

Custom-made teeth whitening trays that come directly from the provider or your dentist are generally considered more effective as they are made to fit your mouth properly. This means there’s no room for leakages or the tray slipping off. Check out one of these Hismile reviews if searching for a whitening product directly from the provider/manufacturer.

However, teeth whitening trays from dentist cost a lot more than your local store.

Even though most over-the-counter trays are not customized to fit your teeth, some are pretty good as they are flexible enough to fit your mouth.

How Do Teeth Whitening Trays Work?

Depending on the brand or model you opt for, some teeth whitening trays are pre-filled with a peroxide-based gel or whitening agent. Others come as a kit — you get the teeth whitening trays with syringes that contain the whitening gel. All you have to do during each whitening session is fill the trays with the required amount of peroxide-based whitening agent.

Unlike in-office whitening, you will have to use teeth whitening trays for longer. This is because the whitening agents have lower concentrations of hydrogen peroxide or other whitening agents.

The main reason behind this is that higher concentrations of the whitening product can be harmful to your teeth and surrounding tissues (gums and cheeks) if not used properly. This is why you can only get the dentists as the only people permitted to administer such concentrated levels of peroxides.

Depending on the product, you can use it for a few minutes for each session, while others may require you wear them longer (including throughout the night).

Teeth Whitening Trays Before and After

Teeth whitening trays are known to be quite effective, as long as you pick the right brand or product. It is also advisable to consult with your dentist before settling on any teeth whitening product, especially if you have sensitive teeth and (or) gums or, at least, choose a top teeth whitening for sensitive teeth product.

Here are a few teeth whitening trays before and after images to consider:

How to Use Teeth Whitening Trays

One of the biggest concerns people have is asking ‘is teeth whitening safe?’ Generally, it all depends on the methods you use, but technically, teeth whitening is safe.

Even if you’re using custom-made trays, whitening treatments are only effective when used correctly. Failure to follow the proper instructions to the letter may increase the risk of tooth sensitivity, pain, or even damage the enamel.

Here’s a general guideline for the correct way to use teeth whitening trays:

1. Prep the teeth beforehand

Thoroughly brush and floss your teeth before each whitening session. You can also use desensitizing products (like gel or toothpaste) if you have sensitive teeth to avoid irritations associated with the whitening agents.

2. Insert the gel as instructed

Always read the instructions on the product or follow your dentist’s instructions if custom-made. Failure to adhere to the instructions, especially how you apply the gel and how much should be used, can lead to unsatisfactory results, or worse, irritations.

3. Firmly push the trays into place

Ensure that the tray you use firmly fits into place and that no leakages can be noticed. Remember not to swallow any of the bleach, and you can either spit or wipe it off with a clean cloth.

4. Wear for the directed period

Only wear the trays for the allocated time limit. Do not exceed as the peroxide may start to wear out your enamel.

5. Rinse after use

Rinse your mouth with clean water to remove any remaining gel.

6. Clean the trays and store them properly

You need to clean and wipe out any remaining gel from the trays before storing them properly until the next use.
