A bright smile can help you feel more confident. Over time, teeth can become yellow or stained. This can happen because of food, drinks, smoking, aging, or poor oral hygiene. Many people ask their dentist near you about safe ways to improve the colour of their teeth. One common treatment is teeth whitening.
In this blog, we will explain how teeth whitening works, what causes stains, and how long the results last.
Why Do Teeth Get Stained?
Your teeth have two main layers. The outer layer is called enamel. It is hard and protects your teeth. Under the enamel is dentin. Dentin has a yellow shade.
Stains can be of two types:
- Extrinsic stains
These stains are on the outer surface of the enamel. They are often caused by:
- Coffee
- Tea
- Soda
- Red wine
- Tobacco
- Intrinsic stains
These stains are inside the tooth. They can happen due to:
- Aging
- Certain medicines
- Injury to the tooth
- Too much fluoride
Both types of stains can make your teeth look dark or dull.
What Is Teeth Whitening?
Teeth whitening is a dental treatment that helps remove stains and lighten the colour of your teeth. It does not damage the tooth when done correctly. It uses safe whitening agents that are approved for dental use.
Most whitening products contain hydrogen peroxide or carbamide peroxide. These are bleaching agents. Dentists use controlled amounts to protect your gums and enamel.
How Teeth Whitening Works
Many patients want to know how teeth whitening in Edmonton works. The process is simple to understand.
The whitening gel contains peroxide. When it is placed on the teeth, it breaks down into small oxygen molecules. These oxygen molecules enter the enamel and reach the dentin layer.
The oxygen reacts with the stain molecules. It breaks them into smaller pieces. As stain molecules become smaller, they reflect less light. This makes your teeth look lighter and brighter.
The structure of your tooth does not change. Only the stain particles are broken down.
Professional Teeth Whitening at a Dental Clinic
When you visit a dentist near you for whitening, the treatment is done safely in a controlled setting.
Here is what usually happens:
- The dentist checks your teeth and gums.
- Your teeth are cleaned to remove plaque and tartar.
- A protective barrier is placed on your gums.
- The whitening gel is applied to your teeth.
- In some cases, a special light is used to activate the gel.
- The gel stays on for a short time and may be reapplied.
The whole visit may take about 60 to 90 minutes. Professional whitening is stronger than store products. It gives faster and more even results.
At-Home Whitening Options
Some patients use whitening trays or strips at home. Your dentist may provide custom trays that fit your teeth. These trays hold the whitening gel close to your enamel.
Store-bought kits are also available. However, they are weaker than professional treatments.
It is always better to consult a dentist before using any whitening product. This helps protect your enamel and gums.
How Long Does Teeth Whitening Last?
A common question is, How long does teeth whitening last?
The results are not permanent. Whitening can last from several months up to three years. It depends on:
- Your oral hygiene
- What you eat and drink
- If you smoke
- How often do you get dental cleanings
To make the results last longer:
- Brush twice a day
- Floss daily
- Avoid dark drinks
- Rinse after meals
- Visit your dentist for regular checkups.
Touch-up treatments may be needed over time.
Is Teeth Whitening Safe?
Yes, teeth whitening is safe when done under dental supervision. Some people may feel mild tooth sensitivity after treatment. This usually goes away in a few days.
If you have cavities, gum disease, or worn enamel, your dentist may treat those problems first. Whitening works best on healthy teeth.
Who Is a Good Candidate?
Teeth whitening works well for many adults and teens. However, it may not work on:
- Dental crowns
- Veneers
- Tooth-colored fillings
These materials do not respond to bleaching agents. Your dentist will examine your teeth and tell you if whitening is right for you.
