If you are considering changing the yellowish brownish appearance of your teeth, then you should consider tooth whitening services. The following is all you need to know about tooth whitening before visiting your dentist.

What does tooth whitening refer to?

It is a way of lightening your teeth color by removing the tooth surface. This does not necessarily mean that the entire color of your teeth will change but it helps to lighten the shade of color on your teeth.

Why should you have tooth whitening?

Darkening of teeth is also caused by the kind of foods you consume and lifestyle habits like smoking. Coffee, blackcurrant juice, wine and some other foods contain colors that affect the color of your teeth. Teeth also darken from the use of particular antibiotics.

You may also have a grey shade on your teeth or white spots. These are signs of tooth decay or an infection while your tooth was forming.

What is the procedure for tooth whitening?

The common method for whitening of teeth is professional bleaching. Your dentist usually assesses your condition to check if tooth whitening suits you. They will proceed to offer you different options for whitening.

The most popular option for whitening is home whitening that is supervised by your dentist. Your dentist will make trays that fit your mouth to shield the gums. You are directed on how to apply whitening gel on these trays and what routine to follow for inserting and applying the gel.

Another kind of whitening is chair-side whitening.  This procedure is the same as the first except that your dentist does everything. Your dentist will insert a rubber shield in your mouth to shield your gums. Then he/she will apply a whitening product on your teeth with a special tray.

Whitening products contain hydrogen peroxide. As this ingredient breaks down, oxygen goes into your dentine and enamel making the tooth color appear lighter.

How long do the effects of tooth whitening last?

Your teeth can remain white for close to three years. Nevertheless, the effects of tooth whitening normally vary based on the person. The effect does not last long if you consume products that stain your teeth such as coffee and red wine. Engaging in smoking will also make the effects of whitening short-lived.

Are there side effects?

You may experience sensitivity to cold weather after or during the treatment. You may also feel discomfort in your gums, have white patches on your gum line or even have a sore throat. These symptoms are temporary and usually disappear once your treatment is complete.
