Yes, professional teeth whitening is safe when performed or supervised by a qualified dentist. Results typically last from 6 months to 2 years, depending on your dietary habits and oral hygiene. Here's what you need to know before getting started, according to our team in Sainte-Marthe-sur-le-Lac.
Quick Answer
- Professional whitening is safe and approved by dental associations
- Temporary sensitivity is the most common side effect — it fades within days
- Results last from 6 months to 2 years
- In-office whitening is more effective than over-the-counter products
- Whitening doesn't work on crowns, veneers, or fillings
Does Whitening Damage Teeth?
Professional whitening uses hydrogen peroxide or carbamide peroxide at controlled concentrations. Studies show that these agents, when used as recommended, do not permanently damage enamel. The dentist first checks your teeth and gum health to ensure you're a good candidate.
Possible Side Effects
- Tooth sensitivity: common but temporary (1 to 3 days). Sensitivity toothpaste can help.
- Gum irritation: mild and temporary if gel contacts the gums.
These effects are generally mild and resolve quickly. Whitening is not recommended during pregnancy or for children under 16.
How Long Do Results Last?
Duration varies based on several factors:
- Coffee, tea, red wine, or tobacco consumption
- Brushing and flossing frequency
- Regular professional cleanings
On average, results last 6 months to 2 years. Periodic touch-ups can extend the brightness.
Professional Whitening vs Over-the-Counter Products
Pharmacy-sold strips and gels contain much lower peroxide concentrations. They may slightly improve shade but don't offer the same effectiveness or safety as supervised treatment at a dental clinic.
Frequently Asked Questions
Does whitening work on all teeth?
Whitening is effective on natural teeth. It doesn't change the color of crowns, veneers, fillings, or implants. That's why a prior consultation is essential.
How many sessions are needed?
Typically, one to two in-office sessions are enough to achieve the desired shade. At-home tray treatment can complement the result.
Is natural whitening (charcoal, baking soda) effective?
These products are abrasive and can damage enamel over time. They don't penetrate enamel for true whitening. Professional whitening remains the safest and most effective method.
