Teeth whitening is a recurrent technique to improve the smile. Teeth can darken or acquire certain shades due to various factors such as smoking, poor hygiene, chromogenic bacteria present in the oral cavity… but also certain foods and drinks such as coffee, wine, tea or food coloring stain them.
A dentist can perform teeth whitening on anyone with a healthy mouth, free of caries and with adequate oral hygiene. There are different types of teeth staining, so the professional must assess whether or not teeth whitening is the right treatment for the patient. We have several techniques and whitening products.
Whitening products, the most common of which is hydrogen peroxide, are used in different concentrations depending on the case to be treated. This product can be applied at home following the indications given by the dentist. Often the whitening product is combined with light and heat, sessions with whitening lamps in the office and under the supervision of the dentist that accelerate the process. The number of sessions will depend on each case.
Tooth whitening, care at home
Once the process is finished, it is possible that the patient may feel a little dental sensitivity, always in a temporary way. This will be controlled with toothpaste, gel and a desensitizing mouthwash, this treatment will also help to protect the tooth against external agents. In no case does the whitened tooth suffer any damage or injury.
It is important to keep in mind that dental aging causes the deterioration of the enamel, making the external structure more translucent, evidencing the internal part of the tooth that becomes more yellowish with the passing of the years. It is important to note that a previously whitened tooth will respond better to such aging.
After whitening treatment it is possible to eat and drink normally, although certain foods and drinks should be avoided during the period of stabilization of the new color obtained. These limitations will be indicated by the professional once the procedure is completed. The results of whitening are maintained in the long term, always following certain precautions in terms of oral hygiene, food and harmful habits.
