How Often Should You Use Whitening Strips to Whiten Your Teeth?

As we mentioned earlier, whitening strips are the easiest way to whiten your teeth. In addition, these strips are economical and also give quick results. 

There is a cleaning or whitening agent in the strips. This chemical remains inside of the strips. When you unpack and uncover the strips, you can get in touch with the chemical. The whitening agent of the strips makes contact with the enamel of your teeth and eventually whitens them. 


Pretty simple, isn’t it? Now you know how to use teeth whitening strips. But how often should you use whitening strips? Is there a clear answer or procedure to follow? 

Sadly to say, there is no clear answer to this question. But hey, that is not a big deal. Because we have an average assumption about the procedure to follow. 

Generally, people need to apply the whitening strips once a day and continue the process for two weeks. But it can differ depending on the person and product. You may need to apply the strips twice a day and continue doing so for three weeks. 

Try to follow the guidelines provided with the whitening strips. And if possible, consult with your dentist too, about the start or progression of whitening your teeth. 

Can you use whitening strips every day?

Yes. To be more specific, you have to use the whitening strips every day to make them effective. You may not find expected results if you give too many gaps between a whitening session (two to three weeks).

How often should you use Crest 3d white strips?

You have to use Crest 3d white strips every day for two weeks to a maximum of 20 days. And you have to keep the strips for thirty minutes. After thirty minutes, it will be okay to throw the strips in the trash bin.

Crest whitening strips: before and after

You may have a yellowish or dark set of teeth. It can happen for many reasons. One of the effective solutions to this problem is to use whitening strips. 

Among the whitening strips, Crest strips have made quite a name for themselves. Trust us, they are effective. After applying them for a specific time, you will see the result yourself.

How often can you use whitening strips per year?

Usually, people do two teeth whitening sessions per year. That makes the answer two. But the effectiveness of the whitening process mostly depends on your eating habits. If you eat more dark beverages, there is a higher chance that your teeth won’t remain white for long. 

So, if you can keep your food habit in control, using whitening strips once a year will be enough.

Is It Safe To Use Teeth Whitening Strips At Home?

The answer depends on the measurement of your safety grade. For example, you have both the options to use professional help and do the whitening process with strips at home. In this case, the safest option is to use professional help to avoid complications. 

And if you only want to use whitening strips and don’t have the other option, we say it is fairly safe. Don’t worry much. Just follow the steps instructed carefully, and you will be fine.

How to Use Whitening Strips?

Okay. Now you know what whitening strips do. But how do you use them? What is the exact procedure to follow while applying whitening strips? This section is here to provide the appropriate procedure to apply teeth whitening strips step by step. Read on. 

Step 1: Brush your teeth before applying the whitening strips

It is a great idea to brush your teeth before applying the teeth whitening strips. By doing so, you will make sure no excess stains and food particles are there. But remember one thing. Don’t brush with fluoride toothpaste. 

If you do so, you will risk the whitening agent of the strips not working. And you surely don’t want that to happen, do you? 

Step 2: Measure your teeth and adjust the strips

You won’t find this step anywhere else. Then why are we telling you this? It is because we care for you. It is a preventive measure to protect the gum tissues of your mouth. 

You shouldn’t make contact with your gum tissues with the whitening strips by any means. To assure it, measure the height of one of your teeth first. After that, multiply the figure by two. 

Now, you have to measure the width of the strips. If the figure from your teeth measurement matches the figure from the strips, you are ready to go. If not, cut the strips according to your need. 

Step 3: Gently apply the strips over the top row teeth

Now that you have measured your teeth and strips, you should gently start applying one set of the strips on top of your front row teeth. Make sure you apply the strip in a way that half of the strip still hangs. 

Step 4: Fold the whitening strip

You have to fold the remaining hanging strip in the inside part of your front row teeth. Be careful and make sure the strip doesn’t make contact with your gum. 

Step 5: Apply the strip over the bottom row teeth

After you are done with the upper row teeth, it is time for you to work with the bottom row. 

Follow the same process mentioned in step three over the bottom row teeth. 

Step 6: Fold the whitening strip

Fold the remaining hanging whitening strip in the inside part. 

Step 7: Keep the strips for around 30 to 60 minutes

One of the surprising factors about whitening strips is that they can even work within only five minutes. Well, that is what the manufacturers claim. And as you are using over-the-counter accessories to whiten your teeth, you have to follow every instruction from that particular manufacturer. 

The amount of time needed to keep the strips on to work differs on the brands and products. Don’t be surprised. In most cases, you should be done within thirty to sixty minutes. But don’t forget to follow the instructions for that particular product. 

Are There Any Bad Sides of Using Whitening Strips? 

Yes, there are. If you do the application wrong, you may fall into some complications. Sometimes, some complications may happen even if you do everything right. 

If your teeth are too sensitive infected, you may fall into further problems by applying the teeth whitening strips. Let’s see what the complications are –

Gum irritation

Things can’t get worse than having gum irritation. If you use teeth whitening strips in the wrong way or leave them for too much time, you may face gum irritation

What does gum irritation look like? You will have swollen and red gum in that case. The gum will look like it is ready to bleed at any time. In addition, some plaque may even stack over the gum. 

Yeah, things will be pretty bad. That is why being cautious all the time is the key. 

Tooth sensitivity 

If you do things wrong while applying whitening strips, you may even face sensitivity issues within your teeth. You may know how irritating the feeling is to have a sensitivity issue. 

Try to avoid making mistakes and stay put with the instructions. We hope you will be fine from having sensitivity. 

Tooth damage

Another complication may happen for doing something wrong with the whitening strips. You may even damage one of your teeth! Yes, we are not joking. 

We know you don’t want that. That is why we suggest you take applying the strips very seriously. 


Can I use mouthwash after whitening strips?

Yes, you can. Doing mouthwash after using whitening strips won’t damage your gum or teeth. But you should be gentle while doing the mouthwash. Don’t be harsh. 

You can use any manufacturer’s mouthwash. It is okay. But it will be better if you use the mouthwash from your whitening strips’ brand. There will be a good synchronization if you manage to do so. 

Can I brush and floss my teeth after using whitening strips? 

There is no prohibition on brushing and flossing after using whitening strips. Just make sure you brush or floss gently. Because doing those in a harsh way can potentially irritate or damage the gum or teeth.

Should I rinse after whitening strips? 

Yes. You should rinse your mouth with water after you pick out the strips from your teeth. You may also try using brushes to clean the teeth. Whatever you do, make sure you don’t swallow much gel (of the whitening strips). Doing so may intoxicate your stomach. 

What happens if you leave whitening strips on too long? 

It may sound like a good idea that if you leave the whitening strips long, they will be more effective. Well, in theory, it may. But in reality, you will face some complications like enamel damage or tooth sensitivity. That is why we don’t recommend doing so. 

Can I sleep with teeth whitening strips? 

No, you can’t. Even if you can manage the duration of your sleep, you can’t control your teeth movement while you are asleep. So, you should not sleep with teeth whitening strips. 


Using whitening strips is not the best way to whiten your teeth. People use this method only because it is hassle-free and cheap. You have to whiten your teeth every six months or a year. So, eventually, you have to whiten your teeth again if you want to keep your shiny white teeth. 

In general, you need two weeks and apply the strips once a day in that period. But as we mentioned, it differs with the brands and products. The best way to have an effective output is to follow the instructions of the particular product you are buying. 

That’s all for today. Hope it helps.
