Is it really bad to whiten teeth with cavities?

Basic care before: Restoring decayed teeth is more important than cosmetic ones. If left alone can quickly become troublesome. If decayed areas are small and not very deep, you could whiten first, but it could be painful. Sensitivity is the most frequent complaint when whitening healthy teeth. Whitening teeth with cavities of any size could lead to problems, especially since it opens the dentinal tubules in teeth.

Whitening: Whitening products should be used on healthy teeth only. See your dentist, make a treatment plan and reward yourself at the completion of the treatment plan with a beautiful white smile. Patients who complete treatment in my office, get free whitening.

Yes: Yes as it will cause added sensitivity.

Yes: Expect greater sensitivity and just always keep in mind that your decay isn't getting smaller left untreated. And you're not achieving a healthy white smile when you still have decay.

Whitening: You may want to reevaluate your oral health priorities. Whitening teeth with decay is like painting your car that is rusting before you take care of the rust. Regain your oral health first, by taking care of the decay and any other issues diagnosed, then whiten your teeth as a reward to yourself for achieving a healthy smile. Then stay healthy by having regular check ups.
