Can I whiten my teeth too much? My dentist told me to wait six months before repeating zoom whitening. She said I could damage my teeth if I overdid it, but I wanted to see how white my teeth could get. I have been bleaching my teeth every two weeks for four months. I felt some sensitivity in my teeth and went to the dentist. After examining my teeth, my dentist asked me about whitening, and when I told her that I had been whitening every two weeks for four months, she asked me to stop. She also said that she would not complete another in-office whitening session unless it was necessary. I was hoping to get another in-office session in December for the holidays. Is my dentist correct? Do I need to stop whitening my teeth? Thank you. Torri
Thank you for your question. Your dentist examined your teeth and asked questions to determine why your teeth are sensitive. Excessive teeth whitening is likely the culprit.
How Much Teeth Whitening Is Too Much?
Teeth whitening is too much when it creates lingering sensitivity and wears away the enamel. Over-bleached teeth can become brittle, thin, and discolored. According to the American Dental Association, factors that affect teeth sensitivity with whitening include:
- Concentration of carbamide or hydrogen peroxide
- How long the bleaching gel is in contact with your teeth
- Intensity and duration of light use
- Presence of adhesive restorations
If your dentist recommends that you pause at-home and in-office whitening, it may be time to give your teeth a break to avoid damaging them.
How Can You Prevent Teeth Stains?
Although you cannot prevent teeth stains altogether, you can minimize them. Limit or avoid the things that can increase staining, including:
- Dark berries
Rinse your mouth with water immediately after consuming substances that stain teeth. It will dilute the ingredients and limit their staining effectiveness.
If you do not fully understand why your dentist recommends a pause in teeth whitening, contact her to request more information.
