Disadvantages and Dangers of Tooth Whitening

Madhura Pandit Nov 20, 2018
We all wish for perfectly white teeth. Today, teeth whitening is very easy. But, there are a few potential hazards of whitening teeth. Here is more information on the same.
Along with whitening procedures, one needs to give up habits that lead to teeth staining like smoking, having excess tea or coffee, having foods with excess food coloring, etc. Continuing these habits will negate the effects of teeth whitening.
When a person smiles, teeth are the first thing to be noticed. A beautiful smile boosts your confidence. Cosmetic dentistry is quite advanced today. Teeth whitening is much in demand. It can make yellow, brown stained teeth whiter and more beautiful. Various ways of teeth whitening include bleaching, laser teeth whitening, whitening toothpastes, strips, etc.
Although several do-it-yourself kits or over-the-counter equipment is available, preferably, you should go to a dentist for whitening your teeth. But, is whitening safe for teeth? Before going for the procedure, note that along with the advantages of having white teeth, there are a few side effects in teeth whitening.

Side Effects of Teeth Whitening

  • The most prominent side effect is that your teeth become sensitive to temperatures. You will feel it when you have hot or cold drinks.
  • Sometimes, the whitening becomes uneven. It can occur naturally as the effect of bleach is not even for every tooth. This may even result in patchy appearance on your teeth. The irregular whitening looks as if you have undergone a failed procedure.
  • Frequent use of bleach or other chemicals may result in erosion of the teeth enamel. Teeth enamel helps in preventing decay of your teeth. Hence, there can be higher chances of tooth decay.
  • You may suffer from sore gums immediately after you have completed the procedure. Irritation of gums may also be observed.
  • Sometimes, the chemicals used for whitening teeth may cause allergic reactions. Therefore, make sure you speak with your doctor about allergies before going for the procedure.
  • There are chances of swallowing the chemicals mistakenly. If these chemicals are consumed, you may feel nauseous and even vomit. However, this is rare.
  • It is not advisable for young people (under 16 years of age) to undergo teeth whitening. Similarly, pregnant as well lactating women must stay away from it.
  • Talking about disadvantages of laser teeth whitening, it is very expensive as compared to other procedures. Secondly, it can sometimes be painful.

What to Do

So, what precautions do you need to take in order to prevent these uncomfortable side effects? Here are a few things that you can do:
  • As mentioned, it is recommended to have the procedure done with the help of a dentist. He will use the right technique, chemicals, and products. Sometimes, teeth are extremely stained or discolored. In that case, artificial whitening does not produce any noticeable effect. A dentist will help you decide whether you should go for teeth whitening or not.
  • Hydrogen peroxide is the main constituent of teeth whitening products. More the content of hydrogen peroxide, whiter your teeth will get. But, excess of hydrogen peroxide is not good for teeth.
  • Sometimes, people tend to continue whitening teeth for a longer duration, which is not recommended. Excessive use of bleach can result into severe irritation of gums or other dental problems. Teeth whitening trays that are commonly used should not be used frequently.
  • There must be a suitable gap between two consecutive procedures.
  • When trying it at home, you must read the instructions carefully before use. Avoid making excessive use of these products as they may result into damaged teeth. If you notice any side effects, you must immediately see you dentist.
There are a couple of things you need to know before going for teeth whitening. The products and procedure is to be followed as recommended. Following it incorrectly may not give desired results. Secondly, whitening only works on natural tooth surface.
Therefore, if you have caps or veneers, it might not work. The doctor will also advise you on a diet plan (for 1-2 days) to follow after completing the whitening procedure.
Most of the side effects of whitening teeth are temporary. But, you need to be very careful before using any products. You must take professional advice before going for any teeth whitening methods. If done properly, you will definitely succeed in having that million dollar smile!
