A dental check-up is essential before undergoing in-office teeth whitening to identify and address any underlying oral health issues. Your dentist will check for any existing dental problems such as cavities, gum disease, or tooth sensitivity that could be exacerbated by the whitening process.
Additionally, it's important to note that whitening treatments do not affect the color of dental restorations like crowns, veneers, or fillings. By assessing your overall oral health and understanding the limitations of whitening, your dentist and hygienist can provide the best treatment plan to achieve your desired smile.
