Dr. Katie Graber Answers Common questions about teeth whitening:1. What is the difference between in-office whitening, take-home whitening kits, and over-the-counter products?
Tooth whitening is very popular and is most effective when monitored by the general dentist. Each person has teeth that have individual characteristics and the general dentist can recommend the product that is best for them. In general, the options available in the dental office, such as in-office bleaching and take home whitening kits are more effective than the over-the-counter products. The cost is usually higher as well due to the office visits and monitoring. Some staining of teeth is actually inside of the tooth structure and does not respond well to conventional whitening. Sometimes these teeth require bonding or veneers – ask your dentist what is right for you!
2. Do whitening toothpastes really make a difference?
Whitening toothpastes can help with mild stains. They are usually more abrasive than “regular” toothpastes so are not appropriate for sensitive teeth. Also, with any toothpaste, check to make sure it is approved by the ADA (American Dental Association).
3. How do I get my teeth whiter without them looking unnatural?
Ask your dentist – they can help you decide!
4. Can I use whitening products on my teeth while receiving orthodontic treatment?
It is not recommended to use whitening products during orthodontic treatment. Usually there is something bonded to the front of your tooth (brace or Invisalign) and the whitening will not permeate that area. After the appliances are removed, there would be a mark in the area of the brace.
5. Can I use whitening products on my dentures?
Whitening products do not change the color of false teeth. That includes dentures, crowns, bonding and veneers. Whitening should be completed prior to the fabrication of any type of false teeth.
6. What is the best over-the-counter whitening product?
There are many good products available. Ask your general dentist!
7. After I’ve received in-office teeth bleaching, what’s the best way to maintain my bright smile?
Avoid foods with lots of artificial coloring. If you have something that has a strong color (example: coffee, mustard, red wine) try to brush afterwards. If brushing is not possible, swish with water.
8. What foods and beverages will discolor my teeth? Which foods and beverages taste good but won’t discolor my teeth?
Foods with strong colors (natural or artificial) can contribute to tooth staining. Watch for food dyes on the ingredient lists. Natural foods like coffee, tea, wine, and mustard can also stain the teeth. Usually, dietary restrictions are unnecessary. Utilize the proper home care (brushing and flossing) with regular visits to the dentist to prevent stains from becoming a problem.
9. Is tooth discoloration genetic?
Some tooth discoloration is intrinsic (inside of the tooth material.) The inside-type stains are due to a variety of factors including: genetics, childhood illness, prescription drugs, etc. This type of stain does not respond well to whitening products. As mentioned above, ask your dentist what is best for you!
