Many wonder whether teeth whitening is the right choice. Having white and healthy teeth is a common desire; bright teeth improve self-esteem, communicate well-being and can make the difference in important moments such as a job interview, a ceremony or a first date.
But what to do when your teeth appear yellow or stained? Modern technologies today offer safe, rapid and effective solutions. In this article we analyze the most common causes of yellowing teeth and the treatments available to achieve a whiter smile.
Why do teeth turn yellow?
Teeth color is determined genetically and varies from person to person. However, over time it is physiological that the enamel thins, revealing the underlying dentin, which is naturally more yellowish.
Added to this natural process are other external factors that can intensify yellowing:
- Poor daily oral hygiene
- Cigarette smoke
- Regular consumption of coffee, tea, red wine or sugary drinks
- Taking specific medications
- Pregnancy and hormonal changes
- Dental necrosis or root canal treatments
Prevention is essential: accurate oral hygiene (brushing, flossing, periodic professional cleanings) is the first step to maintaining a healthy and brilliant smile.
How to remove stains from teeth?
One of the most effective treatments for eliminating surface pigmentations is air polishing, an advanced hygiene technique.
Uses a controlled jet of air, water and low abrasive powder to polish teeth and remove stains caused by smoking or food.
Air polishing is performed after the removal of plaque and tartar and is particularly suitable for:
- Heavy smokers
- Patients with superficial stains
Those who want immediate shine before important events
The treatment is quick (15-20 minutes), painless and can be completed with the application of desensitizing products. A periodic evaluation is recommended to verify the effectiveness of home hygiene habits
Teeth whitening: professional or home?
In addition to the mechanical removal of stains, it is possible to intervene in a more profound way with actual whitening treatments, which act on the internal structure of the tooth.
The available options are:
- Professional in-office whitening (chairside)
- Home whitening with personalized masks
Both involve the controlled use of whitening agents (hydrogen or carbamide peroxide) in different concentrations depending on the treatment.
Professional chairside teeth whitening
This treatment is carried out directly in the office by a qualified dentist. It uses highly concentrated gels (up to 45% hydrogen peroxide), activated by LED or laser lamps which accelerate its effectiveness.
Main advantages:
- Immediate results visible after a 60-90 minute session
- Average duration of effect: 12 to 24 months
- Safe and controlled treatment
- Possibility to repeat it over time
The only possible side effect is a temporary slight sensitivity to heat or cold, which tends to resolve spontaneously. It does not cause any damage to the tooth enamel.
Home teeth whitening
Home whitening involves the use of masks made to measure for the patient. The trays are filled with a carbamide peroxide-based whitening gel and worn for a few hours a day, for a period of approximately 2-3 weeks.
Advantages:
- Gradual and customizable treatment
- Reduced post-treatment sensitivity
- Greater convenience for those who prefer to carry out the treatment at home
The dentist supervises the protocol and provides precise instructions to ensure safe and effective results.
