Is teeth whitening safe? What to know before you start

Whitening is one of the most requested treatments in Erbil. Done correctly, after a check-up and under a dentist’s supervision, it is a safe way to lighten natural teeth. Here is what you should know first.

How whitening works

A whitening gel releases oxygen that breaks down stain molecules inside the enamel. The tooth structure is not removed — the colour becomes lighter. Professional whitening uses gels and protection for the gums that are not available in shops.

Why a check-up comes first

Cavities, cracks or receding gums can make whitening painful. The dentist also checks for fillings or crowns on the front teeth, because these do not change colour and may need replacing afterwards to match.

Will my teeth be sensitive?

Some people feel short, sharp sensitivity for one or two days. It usually fades on its own; a toothpaste for sensitive teeth helps. Tell the dentist if you already have sensitivity before you start.

Who may not be suitable

• Pregnant or breastfeeding women are usually advised to wait.
• Teeth darkened by certain medicines or by an old injury may respond less.
• Untreated cavities or gum disease must be treated first.

Home tricks to avoid

Lemon juice, vinegar, baking soda scrubs and charcoal powders can wear and dissolve enamel. Worn enamel looks more yellow, so they can make teeth darker over time.

How to keep the result

For 48 hours avoid coffee, tea, cola and dark sauces. After that, rinse with water after coffee and tea and keep regular cleanings. Smoking and hookah bring stains back fastest.
