Teeth whitening, as Dr. Arti Gupta explains, is a cosmetic dental procedure aimed at lightening the color of teeth and removing stains or discoloration. Over time, teeth can become stained due to factors like aging, food and drink consumption (such as coffee, tea, or wine), tobacco use, or poor oral hygiene. Teeth whitening treatments can be done either in the dental office or at home with custom-made trays and professional-grade whitening gel. Dr. Gupta emphasizes that professional whitening offers more controlled and effective results compared to over-the-counter products, as it is tailored to the patient's needs and supervised by a dental professional. Whitening can significantly enhance the appearance of your smile, boosting confidence and providing a brighter, more youthful look. However, Dr. Gupta also notes that it’s important to consult a dentist to ensure that the treatment is appropriate for your dental health and to avoid potential sensitivity or damage to your teeth.
