Tooth Whitening
Teeth Whitening is an easy and effective dental treatment to change your teeth colour to a whiter shade. Natural teeth colour varies significantly between individuals and is also easily affected by factors including discolouring and stains.Smoking, drinking red wine, coffee and tea and eating certain foods or taking particular medications can all affect the colour or staining of your teeth.
At Miranda Dental Centre, we can do in-chair teeth whitening, which is completed at the practice with instant results and take-home whitening kits.

The take-home whitening kit allows you to whiten your teeth in the comfort of your own home and over a few weeks.

Miranda Dental Centre is a family-oriented practice. We work as a team. We treat children, adolescents and adults, and this diversity keeps us mindful of our patient’s individual needs to make their visit relaxed and pleasant. We try to schedule appointment times as conveniently as possible.

We advise our patients to maintain good oral hygiene and remind them of their regular visits.

Teeth whitening is one of the most popular ...
... and affordable cosmetic dentistry procedures. It helps remove stains and discoloration, restoring your teeth to a brighter, more youthful appearance.

Is Teeth Whitening Safe?
Yes, when used correctly. The most common side effects are tooth sensitivity and gum irritation, which are usually temporary.
Professional treatments are safest, especially for those with sensitive teeth or dental restorations.
Not Everyone is a Candidate
Teeth whitening won’t work on:

Crowns, veneers, or fillings.
Severely discolored teeth from trauma or medication.
People with gum disease or cavities (should treat those first).
Maintaining Results
Avoid staining foods/drinks (or use a straw).
Brush and floss regularly.
Consider occasional touch-ups (every 6–12 months depending on method).

Teeth bleaching is a form of teeth whitening that uses chemical agents (primarily hydrogen peroxide or carbamide peroxide) to lighten the color of the teeth beyond their natural shade. It’s commonly done to treat deeper intrinsic stains as well as surface stains.

How Teeth Bleaching Works
Hydrogen peroxide breaks down into oxygen, which penetrates the enamel and dentin to remove pigmented molecules.
The result is a visibly whiter, brighter smile.
Types of Teeth Bleaching
1. In-Office Bleaching
Agent Strength: 25–40% hydrogen peroxide.
Procedure:
Gums are protected with a rubber dam or gel.
Bleaching gel applied to teeth.
Optional use of light or laser to accelerate the process.
Time: 45–90 minutes.
Results: 5–8 shades lighter in a single session.
Best For: Deep stains, fast results.
2. At-Home Bleaching (Prescribed by Dentist)
Agent Strength: 10–20% carbamide peroxide.
Includes: Custom-fitted trays.
Time: Wear trays for a few hours or overnight for 1–2 weeks.
Results: Gradual lightening.
Best For: Moderate stains, convenience, maintenance.
3. Over-the-Counter (OTC) Bleaching
Products: Whitening strips, gels, pens.
Agent Strength: 3–10% peroxide.
Results: Mild improvement over 1–2 weeks.
Note: Less effective and more likely to cause gum irritation if not used carefully.
Who is a Good Candidate for Bleaching?
Healthy teeth and gums.
