5 Side Effect of Teeth Whitening

There are a lot of reasons that teeth can get discolored. There are various reasons that teeth gets discolored. But basically it is because of two simple reasons:

You might be interested in:

  • Intrinsic reason

Inside our teeth, there is an inner part called dentin. Over time, the dentin will naturally get darker. The discolored dentin then would reflect through the enamel, making it look yellowish.

The only way that serves as a solution to this matter is by soaking the teeth in with hydrogen peroxide, which can also be called as a whitening gel, or beach to become lighter. When the peroxide is used to whiten teeth, it produces free radicals that would later seep in between the enamel cones. The free radicals would physically shrink the pigment molecules. This would reduce the darkness.

Making the pigment smaller also means that it would reflect less light.

However, a day after your teeth whitening is very important if you follow through this process. This is because the process itself hydrates the teeth. It will be rehydrated once you start eating and drinking again.

  • Extrinsic Reason

Teeth could turn yellowish because of extrinsic reasons as well. This refers to the stains that were left on our teeth after we consumed certain food or drinks. A few reasons why teeth could go get stained; drinking or chewing tobacco, drinking red wine, or coffee.

This can be easily removed with a polish by your hygienist at teeth cleaning or with polishing and whitening toothpaste.

When you clear your teeth of stains, you will be exposing the color of your dentin. However, you will not be able to change the natural color of it.

In order to be able to get a teeth whitening method, you have to consider a couple of factors such as your age, your dental history, the treatment method, the cost of it, along with the type of discoloration that you have.

In general, there are a couple of ways that you can get your teeth whitened:

  1. Administered by your dentist

Your dentist can use several different methods to whiten your teeth, either in the office or at home. Generally, they will be using carbamide peroxide to whiten your teeth. This compound breaks down to hydrogen peroxide and targets the tooth color in a chemical reaction.

The teeth whitening that is done in the office can be very beneficial because it works very quickly. Usually, you will only need an hour treatment or a few visits to whiten your teeth. In-office treatment is also recommended if you have receding gums or abfraction lesions.

1. Tooth Sensitivity

You may notice that your teeth get sensitive during the whitening process, or for a short period after the procedure. This is because of the exposure of the dentin layer during the whitening process.

You are advised to consult your doctor beforehand in case you have tooth sensitivity before you decide to whiten.

2. Soft tissue irritation

This is also known an as chemical burn. Soft tissue irritation may occur if the whitening solution is exposed to the gum tissue during the whitening process. When soft irritation occurs, your gum will appear white immediately after they have come into contact with the whitening solution.

The tissue will return to normal very shortly after the exposure to the chemicals. Prolonged exposure to teeth whitening gels or solution on the gum tissue also may result in the inflammation and redness of the areas affected by the whitening solution.

3. Undesirable result

Depending on the initial shade of your teeth, the results achieved after whitening your teeth may not be what you wanted or hoped for. If you have heavy stains or internal color discoloration, you may not even notice a change in your teeth after teeth whitening.

There is another side effect as well if you whiten your teeth too often. Your teeth may start appearing as grey or translucent. Additionally, teeth whitening doesn’t work if you have caps, crowns, veneers, or fillings.

4. Nerve pain

Laser teeth whitening treatments are significantly more likely to cause nerve pains and sensitivity than other teeth whitening methods. The nerve pain, however, can be reduced by using pain medications such as Tylenol.

5. Enamel Damage

Excessive usage of teeth whiteners can also remove a small amount of enamel, where the stains are found. It has to be used in moderation since the amount of enamel that it removed would be minimal.


There are various methods that exist to whiten your teeth. However, it is suggested that for you to better consult a doctor or a professional in case if you want to whiten your teeth. Off products counter can have a side effect that you do not know if you use it too frequently or in the wrong way.
