Final answer:
Tooth whitening is not indicated for patients with tooth decay, gum disease, hypersensitivity to peroxides, children under a certain age, pregnant or lactating women, and those with certain dental restorations.
Step-by-step explanation:
When is tooth whitening or vital bleaching not indicated for a dental patient? Tooth whitening, also known as vital bleaching, is not indicated for dental patients with certain conditions. These conditions can include but are not limited to:
- Patients with extensive tooth decay or gum disease, as bleaching can exacerbate these conditions.
- Patients with hypersensitivity to peroxides, which are commonly used in whitening products.
- Children under a certain age, typically under 16, as their teeth are still developing.
- Pregnant or lactating women, due to the lack of research on the effects of peroxides on fetuses and infants.
- Patients with restorations such as crowns, veneers, or fillings, especially in the front teeth, as these materials do not whiten and can result in a mismatched smile.
It's important for individuals to consult with their dentist to determine if tooth whitening is an appropriate and safe option for their specific dental health situation.
