Tooth whitening can be a very effective way of lightening the natural colour of your teeth without removing any of the tooth surface. It cannot make a complete colour change, but it may lighten the existing shade. Whitening is among the most popular cosmetic dental procedures because it can greatly improve how your teeth look.
The most common reasons for teeth to get yellow or stained are:
Food and Drink
Coffee, tea and red wine are some major staining culprits. What do they have in common? Intense color pigments called chromogens that attach to the white, outer part of your tooth (enamel).
Two chemicals found in tobacco create stubborn stains: Tar and nicotine. Tar is naturally dark. Nicotine is colourless until it’s mixed with oxygen. Then, it turns into a yellowish, surface-staining substance
Below the hard, white outer shell of your teeth (enamel) is a softer area called dentin. Over time, the outer enamel layer gets thinner with brushing and more of the yellowish dentin shows through
If you’ve been hit in the mouth, your tooth may change colour because it reacts to an injury by laying down more dentin, which is a darker layer under the enamel.
Teeth whitening procedure involves:
Before starting, the dentist will make a record of the current shade of your teeth.
Your teeth would then be polished with pumice, a grainy material used to remove any plaque on the surface.
Your mouth will be isolated with gauze to keep your teeth dry. Retractors may be used to keep your cheeks, lips, and tongue well away from the whitening solution.
A barrier would next be placed along the gum line to further protect it from exposure to the solution.
Next, the teeth would be coated with a whitening solution on the front surface only. The solution typically includes either hydrogen peroxide or carbamide peroxide as the bleaching agent.
Many whitening products require a curing light or laser to activate the peroxide. Once applied, the solution would be left on the teeth for 30 to 60 minutes, or reapplied occasionally, depending on the brand.
Once the optimum shade has been reached (or the maximum time has passed), the teeth would be rinsed. A fluoride application may be used to help ease any tooth sensitivity.Additional visits would be scheduled until the desired shade is reached.
Instructions to be followed after the treatment: you would be advised to avoid foods or beverages with a high level of pigment for at least 24 hours. These include coffee, tea, tomato sauce, tomato juice, yellow mustard, beets, black grapes, candies, and red wine. Smoking or tobacco of any sort would also be avoided.
