Are your teeth stained? Whether the stains are due to tobacco, food or medicine, a dental bleaching will help you smile again. Bleaching may only be performed on healthy teeth and requires a professional recommendation.
Bleaching is essentially based on the application of a special product on the teeth (carbamide peroxide, hydrogen peroxide or sodium perborate for devitalized teeth). The product application is generally performed using a custom gutter (produced by a prosthetic laboratory using a teeth print) . The effectiveness of the whitening product can be further enhanced by activating it with a laser or a specific lamp.
THE ZOOM METHOD (bleaching technique performed at the dentist’s cabinet)
The Zoom-powered whitening method is a patented and scientifically developed tooth bleaching procedure. It is safe, efficient and fast. In less than an hour, your teeth will become remarkably whiter. It is a process that uses a whitening gel (hydrogen peroxide) activated by Zoom light. It acts on the tooth enamel and dentine without affecting the structure of the tooth. The only side-effect observed is a sensitivity to heat and cold which can be treated by applying a fluoride gel after the bleaching. The total duration of this session is 90 minutes including preparation time and before/after pictures. The bleaching itself lasts about 45 minutes only and offers spectacular results.
TEETH LIGHTENING : Comfort & Reliability
The dentist will apply a powerful type of bleaching product (sanding and sand polishing) which passes through the outer ” enamel ” crown and penetrates the dentine to eliminate unsightly spots and dispel various pigments that alter your smile. The protocol is to use a highly concentrated product for an hour on average, regularly renewing the product.This aesthetic intervention can be conducted in a single session with a dentist-surgeon. However, deep shades on the dental structure (i.e. amelogenesis or dentinogenesis), opaque fluorosis, or very marked tetracyclines are absolute contraindications to this type of treatment. Results are generally excellent and long-lasting. Over time, the teeth may lose some of their brightness. It is thus preferable to hold follow-up sessions in order to sustain the brightness of your smile!
DENTAL WHITENING with Opalescence Gel
To enjoy a beautiful dentition and obtain the smile you’ve been dreaming of ”Gel Opalescence Office” (a highly-concentrated cosmetic bleaching gel with hydrogen peroxide containing potassium nitrate and fluoride) is the ideal product.
Before the procedure, the patient should be aware that bleaching will only be effective on the natural tooth part. Indeed, bridges, restorations, and existing crowns cannot be thinned.
This gel cannot be applied on pregnant or under 18 years-old patients.
A report confirming the patient’s gum and oral health is mandatory.
It will be necessary to make sure that the spots on the enamel will respond to the whitening – otherwise, the use of facets would be more effective.
Patients with high tooth sensitivity, worn or fragile enamel, or hypersensitivity to peroxide and/or glycol should avoid this gel.
Teeth whitening is ideal for patients who have healthy, unrestored teeth (no fillings) and healthy gums who would like a brighter smile. Patients with yellow tones to their teeth respond best.
DOES TOOTH WHITENING CAUSE PERMANENT TOOTH SENSITIVITY?
Sensitivity from tooth whitening is always transient. That means if there is any sensitivity caused by the whitening, it goes away within one to two days after the treatment, and the patient returns to the state of sensitivity he or she had prior to starting the whitening process.
HOW LONG DOES TOOTH WHITENING LAST?
Typically you can expect whitening to last from six months to two years, although some studies report results lasting up to ten years. Avoiding red wine, coffee, and a smoking — all of which can cause staining — helps preserve the results.
DOES TOOTH WHITENING AFFECT FILLINGS, VENEERS, OR CROWNS?
Tooth whitening has little or no effect on restorative materials such as porcelain or crowns, but it may temporarily reduce the bond strength between enamel and composite restorations. This is why it’s a good idea to check with your dental professional before beginning any course of tooth whitening.
