Disadvantages of tooth enamel whitening
- An active chemical compound is used for long-term teeth whitening. It interacts with the top layer of enamel, both brightening and thinning it. New generation preparations contain much less aggressive components and acids, but micro changes in the structure of enamel are inevitable. The only way to really safely whiten teeth is with a decorative varnish, which is washed away with the first toothbrushing.
- The procedure is not suitable for people with naturally thin tooth enamel. It is also not recommended to abuse bleaching, as it can lead to hypersensitivity of the teeth. It is better to attend occasional procedures to restore the tone than to have radical whitening once every few years.
- After whitening, teeth become more sensitive to dyes. Stains from drinks and berries will be more noticeable. You can get rid of them with a sanitary rinse, but it is not recommended to brush your teeth more than 2 times a day.
- During the procedure, painful sensations and temporary hypersensitivity may occur. In this case, whitening is suspended, the teeth are treated with a special composition, after which the discomfort is significantly reduced. As a rule, the sensitivity to the whitening procedure decreases noticeably with age.

What do I need to keep in mind before whitening my teeth?
- White teeth only look good when they are perfectly straight. Otherwise it's worth correcting bite problems first.
- If you have gum disease, it is worth refraining from radical dental procedures, including changes in the tone of the tooth enamel
- Professional cleanings are worthwhile before whitening to ensure that the new tone is as even as possible

Complications after bleaching
Changing the color of your teeth is an event that involves serious strain on the patient's body. Despite the extensive experience accumulated in this field, no one can guarantee a certain result. This occurs not only because of differences in conditions, but also in no small measure due to the reaction of the human body to certain influences. Proper reactions to abnormal situations are the key to successful completion of bleaching procedures and minimization of risks.
However, practice knows of many cases where whitening has had serious consequences. What should someone who has decided to get a snow-white smile beware of?
- Penetration of the active agent inside the tooth. If careful preparation has been done, with leaking fillings replaced, tooth decay treated and enamel defects corrected, this option is unlikely. Penetration through the enamel is not capable of harming the body. But if the contraindications are ignored and the peroxide gets into the pulp, it can lead, at a minimum, to severe dental pain. In more severe cases, lesions of the pulp, up to its necrosis.
- Exposure of the bleaching agent to the surrounding tissues. This is quite common, but if you ignore painful sensations in the gum or mucosa area, you can get damage ranging from tissue discoloration to necrosis. Not all changes are reversible and may require long-term treatment.
- Excessive bleaching. If the wrong concentration of gel was chosen, exposure time or number of applications was exceeded, the enamel can become translucent and porous. This will give your teeth an unnatural, painful look and it will be almost impossible to get your teeth back to their former appearance.
- Hypersensitivity of the teeth. Although sensitivity is considered common and normal in whitening, in some cases it takes a hypertrophic form. Oxygen atoms trapped in the dentinal tubules cause extremely painful sensations regardless of the stimulus, and such pains may last for a long time.
