Why Do You Need Whitening?

A need for whitening teeth arises from having yellow teeth discoloration and stains.

Your teeth turn yellow because of extrinsic and intrinsic stains.

Let’s say you drink coffee at least 3 times a day.

Then you also occasionally smoke during work.

Also, you drink wine at night.

Alongside you keep eating sugary and starchy foods.

All of these foods and drinks can stain your teeth.

Extrinsic stains are from those things that come in contact with their teeth.

Coffee and tea contain tannins that stick to your teeth and cause staining.

Plus, they have a dark color.

Red wine can give you a purple stain because of its color and white wine is acidic enough to erode your enamel over time.

Moreover, balsamic vinegar, soy sauce, potatoes, tomato ketchup, and berries all leave a stain on teeth.

Sugary food makes your teeth susceptible to a tooth cavity.

But as it erodes the enamel it also exposes the dentin.

This brings us to the intrinsic causes.

As you eat sugars plus acidic food and drinks, the tooth enamel starts eroding over time.

This is due to the bacteria inside your mouth feeding on sugars and producing acids that wear down the enamel.

As a result, the tooth starts decaying and cavities form inside.

Though, what’s more, crucial to staining is that the dentin is darker in color than the enamel.

Hence, your teeth appear to be yellowish when they have little enamel left.

However, sugars are not only responsible for enamel erosion.

In fact, as you age, your enamel naturally thins down and the dentin becomes more apparent.

Furthermore, intrinsic stains are different from extrinsic ones because of their position and nature.

Extrinsic stains occur on the surface of the tooth.

Hence, teeth whitening remedies or over-the-counter teeth whitening kit can work on them.

However, intrinsic stains are inside the tooth.

Any medical illness, injury to the tooth, fluoride exposure or infection can cause these stains inside besides aging.

If you want to treat intrinsic stains, you need to go to a teeth whitening medical center.

Teeth whitening clinics Sharjah can use laser dental whitening or zoom teeth whitening to get rid of intrinsic stains.

However, kits and home remedies can also work on extrinsic ones.

Though, the time you will require to see changes will be longer.

Hence, patiently use your strips. More on that below.

Using Teeth Whitening Strips to Whiten Teeth

You can easily grab some whitening strips from your convenience store.

They are available over-the-counter without using a prescription.

Furthermore, they are much cheaper than dental whitening procedures however they will not as quickly produce results.

Though, they will still give a noticeable change.

A plastic strip contains hydrogen peroxide gel or another peroxide base such as carbamide peroxide.

You wear these according to the instructions following the exact time written there.

It can clear surface stains over time.

Stronger strips can also reach through your tooth surface and enamel to your dentin and whiten the stains there.

hence, they can also work for intrinsic stains.

Though, results will not be immediately apparent.

You may notice a slight immediate change though, full results are only visible after 4 months.

The strongest strips contain about 14 percent of hydrogen peroxide and milder versions have about 6 percent of it.

That is still less than the bleaching agent concentration in dental treatments.

These are usually more effective than whitening toothpaste and rinses.

While they are generally safe to use, do keep a few considerations in mind while buying this product.

Considerations and Side Effects 

Some strips contain chlorine dioxide.

This material is not suitable for whitening as it is a chemical oxidizer and can erode the enamel.

Rather than whitening, it is actually damaging.

Therefore, check the ingredients carefully and do not purchase any product containing chlorine dioxide.

Do not use the strips longer than instructed.

Follow the instructions carefully to avoid any side effects.

You can experience the following side effects:

Though, if you do not wear them for longer, these are rare.

It is normal to feel some sensitivity in teeth after whitening.

However, recent research shows that whitening strips can result in a loss of protein and collagen in the dentin.

Hence, they can damage teeth.

Though more research is needed to support it this was largely due to the bleaching agent.

This is also why teeth feel sensitive immediately after whitening.

It is best to avoid wearing them when you have dental work and restorations.

Furthermore, you cannot whiten dental veneers in Sharjah or crowns.

You can only whiten teeth, thus, choose your product carefully.

You can also choose one from our recommendations.

But before that, let’s talk about the alternatives to strips.

Other Whitening Systems

Besides strips, you have several other options to whiten your teeth such as:

  • Toothpaste
  • Powder
  • Gel
  • Mouth trays
  • Mouthwash

Whitening toothpaste can whiten your teeth up to one shade.

The toothpaste scrubs surface stains as it contains abrasives and you can use them like your normal toothpaste twice a day.

You will not see these results immediately.

Moreover, they may cause a slight sensitivity and irritation in the gums.

Though gently brushing teeth and using a soft toothbrush may help.

The powder works in a similar manner to that of the toothpaste.

However, it is slightly better at removing extrinsic stains than toothpaste.

Whitening gels are put into strips, trays and even pens.

These contain the active ingredient which is the bleaching agent.

As mouth trays, you will fill it on them and wear the trays for 30 minutes a day.

Some trays have an additional light that helps to activate the whitening ingredient and delivers oxygen to the enamel and dentin to get whiter teeth.

Whitening pens also contain gels that can whiten teeth on the go.

Furthermore, you can apply the gel directly using a small brush.

Do so for 10 to 14 days and two times a day.

Results will be apparent after 4 months while you may notice slight differences occasionally.

Other than that there are mouth rinses and mouthwashes for the purpose of whitening.

However, they may be the least effective.

This is because they come in the least contact with teeth, no longer than a few seconds as you rinse.

Though this is also why they are good for people with sensitivity issues.

You can see results after consistently using it for 3 months.

However, one big side effect of using these rinses is that they get rid of flora i.e. the good bacteria in the mouth.

What Teeth Whitening Kit Should You Use?

It is best to consult your doctor regarding choosing your teeth whitening kit.

Thye may suggest you get professional teeth whitening Sharjah depending on the condition of your teeth.

However, if you only want to get strips then there are three popular ones available over-the-counter:

  • Crest 3D Whitestrips Gentle Whitening Kit
  • Crest 3d White Whitestrips Dental Whitening Kit/Crest 3D Whitestrips Professional Effects
  • Rembrandt One Week Whitening Strips Kit

The Crest strips are especially popular in this category.

The important aspect while choosing is that they cover all your teeth and stick on them.

Moreover, they cleanly come off without causing damage to your teeth.

They contain about the highest concentration of 14 percent bleaching agent.

You apply it once a day for 30 minutes consecutively for 2 weeks.

Remember, your teeth may feel sensitive after using any of these strips. 

While this is normal, it can be stressful for those who cannot bear sensitivity.

In that case, it is better for you to get laser dental whitening.

This procedure helps to whiten each tooth individually using a laser.

The other procedure is to use zoom teeth whitening.

However, that isn’t great for people with sensitivity issues either.

Even if strips cause sensitivity, they result in whitening.

You need to be patient with the results but will see a noticeable change in the shade of your teeth in about 4 months.

Though, this change may not be as dramatic as that from whitening procedures.
