لبخند زیبا و سفید همواره از معیارهای مهم زیبایی چهره محسوب میشود. One of the most common and popular methods to lighten the color of teeth is bleaching, which can produce quick results in changing the appearance of the smile. However, it is very important to know the side effects of teeth bleaching and ways to prevent it. Making an informed choice will help you maintain your oral health while enjoying whiter teeth. In the following, all aspects of this dental cosmetic procedure will be fully examined.
teeth bleaching is a process in which oxidizing agents such as hydrogen peroxide or carbamide peroxide are used to remove surface and deep tooth pigments. These materials penetrate into the tooth enamel layer and cause the decomposition of the coloring compounds. Bleaching is usually done in two main ways: office bleaching (at the dentist's office with light or laser) and home bleaching (at home with a mold and prescribed gel). The main difference between these two methods is the concentration of materials and the speed of teeth whitening.

Complications of teeth bleaching
Although bleaching is one of the most popular teeth whitening methods, like any other treatment, it can come with possible side effects. These side effects are usually temporary and controllable, but knowing them will help you to be more prepared for this procedure and have a better management if it occurs.
Tooth sensitivity and burning

One of the most common side effects of teeth bleaching is temporary sensitivity to cold and heat, which usually subsides within a few days. This situation occurs due to the penetration of bleaching materials into the inner layers of the tooth enamel and the temporary opening of the dentine tubes. The intensity of the sensitivity is different in different people, and it may be felt more in those who have previously had sensitive teeth.
Gum tissue stimulation
Direct contact of the bleaching gel with the gums can cause redness, inflammation or a burning sensation in this area or sometimes, gum periodontitis. This reaction is usually temporary and resolves quickly after the end of the treatment. Observing the correct technique of using the gel and protecting the gums with special tools in cosmetic dentistry reduces the possibility of this problem.
Incidence of toothache
Some people report mild to moderate pain in their teeth after bleaching. This pain occurs more in teeth with small cracks or untreated caries. Fortunately, the pain caused by bleaching is often short-term and can be improved by using simple pain relievers or anti-allergic toothpaste.
Erosion of tooth enamel
In case of repeated or unprincipled use of bleaching materials, there is a possibility of weakening and thinning of tooth enamel. This erosion can gradually reduce the tooth's resistance to decay and cause more problems. For this reason, bleaching should be done with the dentist's opinion and at appropriate intervals.
Danger of allergic reactions
Chemicals in bleaching gels may cause allergies in some people. These reactions are usually accompanied by symptoms such as itching, swelling, redness or a burning sensation in the mouth. If such symptoms are observed, the use of the gel should be stopped and the matter should be reported to the dentist.
Stimulation of soft tissue
Bleaching gel in contact with the tongue, cheeks or lips can cause irritation or a burning sensation. This happens when too much gel is used or accidentally spread. Using the right mold and following the dentist's instructions will help prevent this problem.
Gum burns and blisters

In rare cases, long-term remaining of the gel on the gums can lead to burns or blisters. This condition is usually painful and needs to be treated quickly. Going to the dentist for treatment and using restorative drugs can speed up the healing process.
tooth roughness
Sometimes after bleaching, the surface of the teeth looks a little rough due to temporary changes in the structure of the enamel. This state is usually temporary and can be resolved by maintaining oral hygiene or using special toothpastes. Also, oral saliva gradually makes the surface of the tooth smoother and the feeling of roughness is reduced.
Discomfort and stomach pain (very rare)
If a small amount of bleaching gel is accidentally swallowed, it may cause stomach pain, nausea or gastrointestinal upset. This is rare and occurs mostly in unsupervised home use. In case of such a situation, it is recommended to drink plenty of water and avoid using the gel again until consulting a doctor.
ways Preventing bleaching complications

Although teeth bleaching can cause temporary side effects, by following a few simple and basic measures, the possibility of these problems can be greatly reduced and have a safer experience.
- Choosing a reputable clinic and a skilled dentist: Correct implementation of the procedure and controlling the contact of the gel with the gums will minimize the possibility of complications.
- Use of anti-inflammatory drugs: as prescribed by the doctor, it can be effective in reducing sensitivity and pain.
- Using hypoallergenic toothpastes: helps to remove tooth sensitivity sooner.
- Avoid acidic foods: Acidic substances such as soft drinks or citrus fruits can make tooth enamel more vulnerable after bleaching.
One of the most important steps in bleaching is proper preparation before starting the treatment. Taking some preventive measures can minimize the severity of side effects such as sensitivity, pain or inflammation of the gums and create a safer experience for the person.
Strengthening tooth enamel
To reduce sensitivity, it is recommended to use fluoride or anti-allergenic toothpastes two to three weeks before bleaching. In some cases, the dentist also prescribes fluoride gel or varnish to increase the strength of tooth enamel.
Criminal arrest and oral hygiene

Modification of eating habits
Avoiding acidic and colored drinks and foods such as coffee, tea or soft drinks before bleaching helps to make the tooth enamel less vulnerable to damage. This will not only reduce the intensity of the sensitivity, but the final result will be brighter and more lasting.
Choose the right method
People who have a history of severe sensitivity should consult a dentist to use lower concentrations of bleaching materials or choose a supervised home method. This action makes the bleaching process safer and with less complications. For this reason, if you live in Tehran province, choosing the best dentist in Tehran is very important in the method of bleaching your teeth.
