That seems to be the million dollar question in dentistry, since not all teeth are whitened. And then, what criteria does the dentist use to recommend this treatment?
"We do not whiten the teeth, we remove the yellow and orange pigments from the walls of the enamel prisms. Pigments and dyes that have been deposited in these crystals for years. "
Only large teeth are whitened. It depends entirely on the thickness of the enamel layer. The teeth of the Americans are larger, and of a density greater than those of the Spaniards, so they whiten more and with more effect.
Do we whitewash where there are white fillings? If there are cavities, defects of the neck of the tooth, or old restorations, we must reconvert those problems in health before any treatment. Without exceptions.
Are they bleached more with laser ? It does not have to, the whitening gel is the same, the laser is a light source (light = heat) that activates the product more quickly and also produces more sensitivity. If we use a gel for domestic use and follow the guidelines of the dentist, we will have the same result. At a longer time, the same result, less sensitivity.
Can the patient make normal life? Yes, we must wear normal habits. What is the use of whitening my teeth if I can not eat or drink? Whitening works or not, without half measures. Always start with the upper arch and, if it works, continue with the lower arch.
Should the patient brush the same? Yes, with white paste, without mouthwashes, and we will only brush without paste before putting on the daily bleaching gel every day .
Is sensitivity a negative factor? If the patient has sensitive teeth to the cold we do not recommend it. If it appears during, the appointments are lengthened and the percentage of active product is reduced. In the United States it is typical to use the lowest percentage and for a long time. Percentages higher than 18% of carbamide peroxide have been banned in the EU.
Is it durable ? Yes, although the food colors we use in Spain mean that after two years we need a dose of soda. In most cases, enough to continue having the smile we dream of.
