Question 1

What types of tooth whitening do you offer?

Dr. Nima Dejbod, DMD - Vice President, Washington State Association of Endodontists · Accepted Answer

We offer both internal and external tooth whitening options. Internal bleaching is for teeth that have had root canal treatment and darkened from within. External whitening treats surface stains and general discoloration using professional-grade whitening gels. We also provide combination treatments when both internal and external whitening are needed for optimal results.

Question 2

How does tooth whitening work?

Dr. Nima Dejbod, DMD - Vice President, Washington State Association of Endodontists · Accepted Answer

Tooth whitening uses peroxide-based gels that break down stain molecules in your teeth. External whitening penetrates the enamel to remove surface stains from coffee, tea, wine, and aging. Internal bleaching works from inside root canal-treated teeth to address intrinsic discoloration. The whitening process is safe when performed with professional-grade materials and proper supervision.

Question 3

What is internal tooth bleaching?

Dr. Nima Dejbod, DMD - Vice President, Washington State Association of Endodontists · Accepted Answer

Internal bleaching is a specialized procedure to whiten a single discolored tooth from the inside. After root canal treatment, some teeth may darken due to blood or tissue breakdown inside the tooth. We place professional-strength whitening gel inside the tooth and seal it temporarily, repeating until the desired shade is achieved.

Question 4

What regular whitening options are available?

Dr. Nima Dejbod, DMD - Vice President, Washington State Association of Endodontists · Accepted Answer

For regular whitening, professional options include custom-fitted whitening trays with professional gel, in-office whitening treatments, and whitening strips. Professional treatments are more effective and safer than over-the-counter products. We can coordinate with your general dentist for comprehensive whitening or provide referrals to trusted cosmetic dentists for regular whitening procedures.

Question 5

Is tooth sensitivity normal with whitening?

Dr. Nima Dejbod, DMD - Vice President, Washington State Association of Endodontists · Accepted Answer

Yes, mild tooth sensitivity is common during whitening treatment and usually temporary. This occurs because the whitening gel temporarily opens pores in the enamel. Sensitivity typically peaks 24-48 hours after treatment and resolves within a few days. Using desensitizing toothpaste before and after treatment can help minimize discomfort.

Question 6

How can I reduce whitening sensitivity?

Dr. Nima Dejbod, DMD - Vice President, Washington State Association of Endodontists · Accepted Answer

To reduce sensitivity: use desensitizing toothpaste 2 weeks before treatment, avoid very hot or cold foods during whitening, take breaks between treatments if needed, and use fluoride gel after whitening. Professional treatments often include desensitizing agents. If sensitivity persists, we can adjust the treatment protocol or recommend alternative approaches.

Question 7

How is internal bleaching different from regular whitening?

Dr. Nima Dejbod, DMD - Vice President, Washington State Association of Endodontists · Accepted Answer

Internal bleaching works from inside the tooth and is specifically for root canal-treated teeth that have darkened internally. Regular whitening treats surface stains and works on the outer enamel of all teeth. Internal bleaching is more effective for intrinsic discoloration, while regular whitening addresses extrinsic stains from coffee, tea, wine, and aging.

Question 8

Who is a good candidate for tooth whitening?

Dr. Nima Dejbod, DMD - Vice President, Washington State Association of Endodontists · Accepted Answer

Good candidates for regular whitening have healthy teeth and gums with surface stains or general yellowing. Whitening works best on natural teeth and is less effective on crowns, veneers, or fillings. Internal bleaching candidates have had root canal treatment and have a structurally sound tooth that has darkened. We evaluate each case individually to recommend the best approach.

Question 9

How long do whitening results last?

Dr. Nima Dejbod, DMD - Vice President, Washington State Association of Endodontists · Accepted Answer

Regular whitening results typically last 1-3 years depending on lifestyle habits like coffee, tea, wine consumption, and smoking. Internal bleaching results can last many years but may gradually darken over time. Touch-up treatments can maintain results. Good oral hygiene and avoiding staining substances help prolong whitening effects.

Question 10

What foods and drinks should I avoid after whitening?

Dr. Nima Dejbod, DMD - Vice President, Washington State Association of Endodontists · Accepted Answer

For 48-72 hours after whitening, avoid dark-colored foods and drinks including coffee, tea, red wine, berries, tomato sauce, soy sauce, and dark sodas. Also avoid tobacco products. These substances can re-stain your teeth while the enamel pores are still open. Using a straw for beverages and rinsing with water can help minimize contact with teeth.

Question 11

Can I combine internal and external whitening?

Dr. Nima Dejbod, DMD - Vice President, Washington State Association of Endodontists · Accepted Answer

Yes, combining internal and external whitening often provides the best results when you have a root canal-treated tooth that needs to match your other whitened teeth. We typically complete internal bleaching first, then coordinate external whitening to achieve uniform color across your smile. This comprehensive approach ensures optimal aesthetic results.

Question 12

What does whitening cost and is it covered by insurance?

Dr. Nima Dejbod, DMD - Vice President, Washington State Association of Endodontists · Accepted Answer

Whitening costs vary depending on the type and extent of treatment needed. Internal bleaching typically requires 2-4 appointments, while regular whitening costs depend on the method chosen. Most insurance plans consider whitening cosmetic and don't provide coverage. We offer transparent pricing and will discuss all costs during your consultation.
