While everyone dreams of a Hollywood smile, very few people have naturally bright, white teeth. There are a lot of factors like your diet (coffee, tea, soda) and lifestyle (smoking) that trigger the yellowing of your teeth. If you’ve been wanting to get rid of the unsightly color and stain on your teeth, you’ve come to the right place!
The lightening of the tooth color through the application of a chemical agent to oxidize the organic pigmentation in the tooth is referred to as bleaching. Bleaching treatment is considered to be the most conservative, safe, effective, and minimally invasive method to overcome external and internal tooth discoloration to esthetically alter the color of teeth. The advantage of teeth bleaching lies in those treatments in which the dental structures are preserved. In addition, with the advent of new bleaching agents, the procedure is relatively quick and safe.Bleaching Procedures
Few techniques in dentistry are as broadly applicable as teeth whitening. The indications for teeth whitening are direct patient desire for teeth whitening and/or restorative treatment needs involving the overtly visible smile. While there are few contraindications, special consideration should be applied in cases of sensitivity, pediatrics, or pregnancy. Existing tooth sensitivity is a potential contraindication.
Bleaching techniques may be classified as to whether they involve vital or non-vital teeth and whether the procedure is performed in the clinic or outside the clinic.In-Office Bleaching
Bleaching of vital teeth can be done by in-office method, dentist-supervised home bleaching or self-bleaching using over-the-counter products. An in-office bleaching, hydrogen peroxide (concentrations varying from 15% to 38%) is directly applied on the tooth surface. To accelerate the bleaching process, the bleaching agent may be “photo” activated using light-emitting diodes (LED), plasma arc, quartz halogen, ultraviolet units, and lasers; referred to as “power bleaching”. Application of light-activation method leads to a decrease in treatment time and reduction in adverse effects of bleaching materials. LED applications are usually performed in three to four sessions at seven-day intervals.Home Bleaching
Professionally prescribed home bleaching agent has been proven to be efficient to whiten discolored teeth. Home bleaching is closely monitored by the dentist, thereby ensuring their safety and increasing the effectiveness of the bleaching procedure. The ‘home vital bleaching’ treatment typically employs carbamide peroxide at concentrations of 10 to 16%, which represents low concentrations of hydrogen peroxide but is performed for a much longer time than in-office whitening, applied in individual trays used at night (nightguard), with four-eight hour applications, or during the day, for a period of two to five weeks.Walking Bleaching
This technique provided a dependable treatment modality for teeth bleaching, but its use was obviously limited to endodontically treated teeth. 30%-35% hydrogen peroxide and sodium perborate either in combination or separately are the most commonly used agents for non-vital bleaching of endodontically treated teeth, in which oxidation reaction and degradation of pigment molecules are resulted.
Teeth whitening is safe for healthy teeth and it does not damage the enamel. The in-office whitening gel’s active ingredient is hydrogen peroxide which breaks down into oxygen that removes the stain and makes your teeth whiter while leaving your tooth structure unchanged.
Teeth whitening is conducted in one session. In order to do so, gums are separated and a special whitening gel is applied to the surface of the teeth. Depending on the structure of tooth tissue and the color tone, the doctor decides whether to use laser, halogen or LED to activate the gel.
The entire in-office teeth whitening treatment can take up to 40 minutes. We will do necessary preparations for gum protection, followed by the application of the whitening gel. A special light/lamp may or may not be used. Most of our patients watch Netflix or listen music while they’re getting their teeth whitened, others even fall asleep throughout their treatment.
Results can last at varying lengths depending on your lifestyle and oral hygiene, but in general, they can last for up to a year. Top up treatments every 3-6 months (or as prescribed by your clinician) will help maintain a beautiful sheen, especially if you smoke or drink coffee or tea.
Caring for newly whitened teeth is easy! Maintain proper oral hygiene - brush your teeth twice a day and floss once daily using a fluoride toothpaste. Get your teeth cleaned every 6 months or as recommended by your dentist or hygienist. To maintain the white color of your teeth, avoid acidic and dark-colored foods and beverages like tea, coffee, red wine, sports drinks, carbonated drinks and sauces like tomato, soy and curry.
If there is one tooth, which has a significantly darker colour than surrounding other teeth, it means that it lost its vitality or underwent a root canal treatment. In such a case, the whitening substance is applied by a dentist inside the tooth and is changed every 1-2 day until the desired colour is achieved. It usually takes 1 week and the results are astonishing. The new, whiter colour usually remains for an extended period of time.
