Many of us feel that our smiles are most striking when our teeth look especially white. But unfortunately, soft drinks, tea, coffee, red wine, berries and tobacco can leave behind ugly stains and discolorations. To help you restore your gleaming, bright white smile and to give you an added boost of confidence, professional teeth whitening is the way to go!
Composition of the product: Whitening agents either contain Carbamide Peroxide (take-home treatment) or Hydrogen Peroxide (in-office treatment). Choosing the right concentration and system minimizes adverse effects like mild thermal tooth sensitivity and gingival irritation. The use of a prescription self-applied fluoride gel, or shortened whitening exposure time may decrease the sensitivity.
Pre-Whitening Assessment and Evaluation: The cause of tooth discolouration is usually various and multifaceted. They have been classified as extrinsic and intrinsic discolouration. The extrinsic discolouration is associated with the use of tea, coffee, tobacco, some food products such as blueberries, and red wine. Intrinsic stains may be due to systemic conditions, use of medications after the permanent teeth have erupted or during their development, childhood disease, infection or trauma to a primary tooth while the underlying tooth is developing, trauma to a permanent tooth or natural aging changes and the accumulation of stains that has entered the teeth.
Types of Treatment: There are number of professional products available, either on the shelf or in a dental hygiene/dental clinic, one of them being Philips ZOOM!

Although in-office whitening is performed using high concentration hydrogen peroxide (15%-40%) it has become a widely used, procedure because of its minimally invasive, immediate visible results and no need for client corporation.
Take-home teeth whitening system is considered safe and effective treatment. This technique is performed with a low concentration of hydrogen peroxide (4%-10%) or carbamide peroxide (10%-22%) formulations, which are inserted in custom fitted trays. These trays are placed in the mouth for 30 minutes - 4 hours per day, over the course of 7 to 10 days, depending on the whitening shade you desire.
Safety of Tooth whitening: Frequently, we get asked if teeth whitening is safe? Yes, years of extensive research and clinical studies indicate that whitening teeth under professional supervision of a dental personnel is safe. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4058574/
The amount and frequency of usage are also important factors of considerations to help control any sensitivity or any enamel damage.
Tooth whitening is only effective in removing stains on natural teeth. Any existing restorations, crowns, bridges, fillings or artificial restorations will not respond to any whitening treatment. Whitening may not be effective when teeth are seriously discoloured from antibiotics such as tetracycline.
Longevity of Treatment: Another concern most of us have is how long will the result last? The treatment and their effectiveness vary depending on the type of whitening system. Individuals should know the conditions of their teeth and oral tissues. A thorough examination and dental cleaning by their dental hygienist is recommended before using any whitening system. Overtime the whiter gleam will start to fade depending on factors such as smoking, tea, coffee and red wine consumption or eating foods that stain teeth. To keep your teeth looking their best it is recommend to floss, brush twice daily and occasional touch-ups as advised by your dental professional.
