Teeth whitening works by using a whitening agent, usually hydrogen peroxide or carbamide peroxide, to break down stains and discoloration on the surface of the teeth. This allows the natural whiteness of the teeth to shine through.

Yes, teeth whitening is a safe and commonly performed cosmetic dental procedure when performed by trained professionals. However, it's essential to follow your dentist's instructions carefully to minimize the risk of sensitivity or other side effects.

The duration of teeth whitening treatment can vary depending on the method used and the extent of discoloration. In-office treatments typically take about 30 min, 45 min or 60 minutes session, while at-home treatments may take several days to a few weeks to achieve desired results.

The longevity of teeth whitening results can vary depending on factors such as diet, oral hygiene habits, and lifestyle choices (e.g., smoking, consuming staining foods or beverages). With proper care and maintenance, results can last anywhere from six months to several years.

Teeth whitening is generally safe for most individuals; however, it may not be suitable for everyone, such as pregnant or breastfeeding women, individuals with untreated dental issues, or those with hypersensitive teeth. It's essential to consult with your dentist to determine if teeth whitening is right for you.

Teeth whitening is most effective at removing surface stains caused by factors such as aging, smoking, or consuming certain foods and beverages. However, it may not be as effective for intrinsic stains caused by factors such as medications or dental trauma. In such cases, alternative cosmetic dental procedures may be recommended
