Teeth whitening is the simplest cosmetic dental treatment and often the most underrated. For many people who are considering veneers, professional whitening alone gives a noticeably brighter smile without removing any tooth structure. Here is how the options compare.
Types of professional whitening
| In-office whitening | Custom-tray home whitening | |
|---|---|---|
| How | High-concentration gel applied in the clinic, sometimes with a light, for about 1 hour | Lower-concentration gel worn in custom trays for 1–2 weeks |
| Speed | Immediate result | Gradual |
| Sensitivity | More likely, short-term | Usually milder |
| Typical Istanbul price | about €150–€350 | about €100–€250 |
Combining the two often gives the most stable result. The light used in “laser whitening” mainly speeds things up; the gel does the whitening.
What whitening can and can’t do
- Works best on yellowish discolouration from age, coffee, tea and smoking.
- Less effective on grey discolouration, for example from certain antibiotics or a dead tooth.
- Does not change the colour of crowns, veneers or fillings, which may need replacing to match.
- Doesn’t change shape, gaps or alignment.
Before you whiten
A dental check is important: cavities, cracked teeth and gum recession increase sensitivity and should be treated first. A professional clean beforehand improves results.
Sensitivity
Temporary sensitivity is common, usually for 1–3 days. Toothpaste for sensitive teeth before and after helps. If you already have sensitive teeth, home whitening with lower concentration may be more comfortable.
Keeping the result
- Avoid strongly coloured food and drinks for 48 hours.
- Results fade gradually; touch-ups with home trays can maintain them.
- Stopping smoking helps more than anything else.
Whitening vs veneers
If your teeth are healthy and well-shaped and only the colour bothers you, whitening is usually the better first step. Veneers make sense when shape, size or gaps are also an issue. See veneers in Turkey and Hollywood smile.
