Teeth whitening can be a very effective way of brightening the natural color of your teeth without removing any of its surfaces. This can not completely change color, but it can clear up the existing nuance.
Why would I need to whiten my teeth?
You can whiten your teeth for a number of reasons. Everyone is different; and just as our hair and the color of our skin vary, so are our teeth. Very few people have bright white teeth and our teeth can also fade as we get older.
Your teeth may also be colored on the surface by foods and beverages such as tea, coffee, red wine and blackcurrant. Smoking can also stain teeth.
Tartar or calculus can also affect the color of your teeth. Some people may have spots under the surface, which may be caused by some antibiotics or by small cracks in the teeth that absorb stains.
What does teeth whitening involve?
Professional whitening is the most common method of whitening teeth. Your dental team will be able to tell you if you are fit for treatment and supervise if you are. First, the dental team will put a rubber shield or gel on your gums to protect them. They will then apply the whitening product on your teeth, using a tray specifically designed for your mouth, such as a mouth guard.
The “active ingredient” in the product is usually hydrogen peroxide or carbide peroxide. When the active ingredient is degraded, oxygen gets into the tooth enamel and the color of the teeth becomes lighter.
How long does it take?
Total treatment can usually be done within three to four weeks. First, you will need two or three visits to the dentist. Your dental team will need to create a mouth guard and take fingerprints at the first appointment. Once your dental team has started treatment, you will need to continue treatment at home. This means regularly applying the whitening product for two to four weeks, for 30 minutes to one hour at a time.
However, there are now new products that can be applied for up to eight hours. This means that you can achieve a satisfactory result in just one week.
What are the other procedures?
There is now a laser whitening or “powerful whitening”. During this procedure, a dike is put on your teeth to protect the gums and a whitening product is painted on your teeth. Then, a light or a laser is projected on the teeth to activate the chemical. The light accelerates the reaction of the whitening product and the color change can be achieved more quickly. Laser whitening is said to make teeth lighter up to five or six shades.
How long does armchair whitening last?
Your dentist will need to evaluate your teeth to make sure you are fit for treatment. Once this has been agreed, this procedure takes about an hour.
How much does teeth whitening cost?
Fees will vary from practice to practice and region to region. Laser or laser bleaching will be more expensive than professional bleaching. We recommend that you obtain a written cost estimate before starting any treatment.
How long will my teeth stay whiter?
The effects of bleaching are thought to last up to three years. However, it will vary from person to person. The effect is less likely to last as long if you smoke, eat or drink products that may stain your teeth. Ask your dental team for advice before starting treatment.
What are the side effects?
Some people may find that their teeth become sensitive to cold during or after treatment. Others may have discomfort in the gums, a sore throat or white patches on the gum line. These symptoms are usually temporary and should disappear a few days after the end of treatment.
If any of these side effects persist, you should contact your dentist.
What about home whitening kits?
There are many home whitening kits, including launderers and paint strips. How effective are they?
depends on the amount of bleaching agent they contain.
Home kits are cheaper but they are not always rated in terms of safety and tend to be more acidic. There is a risk that these products will damage your teeth and gums. As teeth whitening is a complicated procedure, we advise you to always talk to your dentist before starting treatment.
Home kit regulations vary from country to country. Kits sold in Europe can not legally contain more than 0.1% peroxide, which is too little to be effective. In other countries where peroxide is stronger, home bleaching is more common. But you have to be careful because some kits sold on the internet may contain mild acids and abrasives.
How are beauty kiosks and beauticians safe?
In Europe and other countries, money laundering can only be legally performed by a dentist. So, teeth whitening by
Beauticians and whitening kiosks is illegal. In Europe, it is illegal to provide bleaching material containing more than 0.1% peroxide (or carbamide peroxide equivalent) to anyone other than a dentist or directly to the public.
What about whitening toothpastes?
There are several whitening toothpastes on the market. Although they do not affect the natural color of your teeth, they can be effective in removing stains. As a result, they can improve the overall appearance of your teeth. Whitening toothpastes can also help the effect of lasting once your teeth have been professionally bleached.
Can we whiten a single tooth filled with root?
Yes. Sometimes, the dead teeth become discolored after filling a root. If the tooth has been treated with the roots, the canal (which contained the nerve) can be reopened. The whitening product is applied from the inside to whiten the tooth.
When could teeth whitening not work?
Whitening teeth can only lighten the color of your existing teeth. In addition, it only works on natural teeth. It will not work with “false” teeth such as prostheses, crowns and veneers. If your dentures are stained or discolored, consult your dental team and ask them to clean them.
How can I heal my teeth once they have been bleached?
You can help keep your teeth white by reducing the amount of food and drink that can stain your teeth. Remember that quitting can also help prevent discoloration and blemishes.
We recommend the following tips for taking care of your teeth:
Brush your teeth last night and at least another time during the day with fluoride toothpaste.
Reduce your consumption of sugary foods and drinks.
Visit your dental team regularly, as often as they recommend.
