Our smile is our calling card and one of the first things people notice about us. With products promising a white, Hollywood smile, it's essential to understand the differences between various teeth whitening methods and consider important factors before starting the process.
External Stains and Maintenance:
Over time, external stains accumulate due to habits like coffee drinking and smoking, causing teeth to darken. To combat these stains, maintaining good oral hygiene and regular visits to the dentist for tartar removal are recommended.
Natural Aging of Teeth:
Teeth consist of multiple layers, and as the outer layer becomes thinner and more transparent, the darker inner layer becomes more prominent. This natural process can lead to a yellowish and speckled shade.
Professional Teeth Whitenig:
Choosing professional teeth whitening over over-the-counter products is recommended. Whitening toothpastes may temporarily improve tooth shade but can potentially damage enamel with prolonged use. Professional whitening alters the chemical composition of teeth, resulting in a brighter shade while preserving enamel integrity. Two types of professional whitening are available:
1. At-Home Whitening:
Precise laboratory-made trays are customized to fit the shape of the teeth. The whitening material is applied at home for a few days to weeks, depending on factors such as initial tooth color and desired end result.
2. In-Office Whitening:
Whitening is performed during one or two dental appointments. The high concentration of the active whitening material requires supervision and achieves results in a short period.
Sensitivity and Restorations:
Some patients may experience sensitivity to heat or cold during whitening. This sensitivity can be managed with tooth sensitivity toothpaste. Existing restorations or crowns in the mouth do not whiten with the teeth and may need to be replaced after obtaining the final color.
Alternative Treatments:
In cases where external whitening is ineffective or minimally effective, dentists may offer alternative treatments. Teeth whitening may be incorporated as a preliminary step to achieve optimal results.
Before undergoing teeth whitening, it's crucial to seek a dental examination, consult with a professional, and choose the most suitable treatment. Dr. Barak Marimski, a dentist at "Machbident" and Itzmam in Tel Aviv, can provide expert guidance and personalized treatment plans for teeth whitening.
