Most people have wished for whiter teeth at one point or another. White teeth are a sign of good health, and they can make your smile look more attractive. In your quest for attractive teeth, you may have tried over-the-counter teeth whitening kits, but these kits aren't as effective as professional teeth whitening. Your dentist can offer superior whitening services. Here are four things you should expect from your first professional teeth whitening treatment:

1. It can take up to two hours.

During your teeth whitening procedure, your dentist will carefully apply the whitening solution to each of your teeth. This can take some time, and after the solution has been applied, it must sit on your teeth for long enough to do its work. This can take anywhere from one to two hours, so make sure to plan your day accordingly. It's best if you aren't in a rush during your treatment, so your dentist can do the best job possible.

2. It can last up to three years.

If you take good care of your teeth, your professional teeth whitening can last up to three years before you need another treatment. In order to keep your teeth looking great, you should avoid food and drinks that could cause staining. Acidic beverages such as soda and wine can cause stains. Dark liquids such as coffee and tea can also stain your teeth. Make sure to brush your teeth every day with whitening toothpaste to remove stains and plaque as they form.

3. It may cause temporary sensitivity.

Some people experience increased sensitivity after having their teeth professionally whitened. This sensitivity will go away in time, but in the meantime, you can reduce its effects by brushing with toothpaste formulated for sensitive teeth. If your teeth are sensitive to cold, you may want to avoid eating frozen desserts until the sensitivity subsides.

4. It can be done using different methods.

There is more than one type of teeth whitening treatment available. Whitening using peroxide or other bleaching agents is the most common and inexpensive option. Laser teeth whitening is also possible. During this procedure, a dentist will use laser light to remove stains from your tooth enamel. Rubber will be used to protect your gums during the procedure.
