Bleaching, whatever the method you have chosen, is not permanent. People with tobacco addiction and who expose their teeth to foods and drinks that alter the color of the enamel can see white fade away in less than 1 month. On the contrary, compliance with some simple rules can keep the color of your teeth unchanged for many months, making it necessary to have another bleaching after a year or more. Therefore avoid smoking and consumption of food and drinks that can stain your teeth. A valid compromise is the use of a straw so that the liquid bypasses the anterior teeth or an accurate washing with toothpaste. Respect good oral hygiene practices: wash your teeth at least twice a day and use dental floss at least once a day. Use whitening toothpaste max once or twice a week to remove surface stains and slow yellowing. The fluoride varnish process can be useful in this case.
Laser or LED dental bleaching?
The two most common instruments used by dentists to activate the chemistry of bleaching gels are the laser and the LED: they have the same function, i.e., they are aimed at the tooth surface that has been covered with the peroxide-based bleaching gel, and they have the same result, that is bleaching.
The timing and the contraindications change: while the laser, thanks to very precise wavelengths, performs a much faster bleaching action, the LED requires more applications. But above all, laser teeth whitening cannot be performed on everyone: it is not recommended for those who are pregnant or nursing, those with chronic diseases and those with damaged teeth; while for the LED there are no contraindications of this kind.
Dental Bleaching Walking Bleach
The walking bleach technique is the perfect combination of studio treatment and home treatment to obtain whiter teeth: it consists, in fact, of making custom- made masks for their dental arches, made of hypoallergenic silicone. Inside, the whitening gel is applied and worn all night, for a few nights. Compared to studio bleaching it has a lower cost and a higher timing, but the results are still performing.
How long does professional tooth whitening take place?
The answer to this question depends only and exclusively on the degree of discoloration of dental enamel in the best of cases, a single session of 30-60 minutes is sufficient; more often, it takes 2-4 sessions for a month, lasting 15-20 minutes.
The maximum effects of tooth whitening will be visible a few days after treatment and, especially if smoke and staining foods are eliminated, can last up to 2 years. In any case, for a smile that is always perfect, it is recommended to repeat the treatment periodically.
Contraindications to tooth whitening
In general, bleaching is a process that does not cause damage to the tooth, and that is performed according to precise dental parameters, with materials and instruments according to the law. The main contraindication is addressed to those subjects who have visible fillings and crowns, since the bleaching does not act on these: they have been made taking into account the color of the teeth prior to bleaching and then, afterward, they will have a different color and will have to be redone, with an additional cost.
