Frequently Asked Questions
Your common questions answered by the experts.
- Preventing Tooth Discoloration after Tooth Whitening In addition to not smoking, you can prevent premature stains by limiting your intake of certain foods and beverages. Sugary snacks and drinks, especially those that are dark in color, will inevitably stain your teeth. By minimizing the amount of stain-causing foods you consume, you can help preserve your smile’s whiteness.
One easy way to limit the staining effect of dark beverages is to drink them through a straw. This will reduce your front teeth’s exposure to the substance, keeping your smile line white and attractive.
- Do Tooth Whitening Agents Alter the Color of Previous Dental Work? No. Dental porcelain and bonding are not affected by tooth whitening agents, and neither are gold alloys or dental amalgam. If you are planning any dental work, such as porcelain veneers or tooth-colored fillings, you should have the tooth whitening done first so that Dr. Marshall can match the restoration material to your new tooth color.
- Disadvantages of At-Home Tooth Whitening Whitening toothpaste contains abrasives or chemicals that may be mildly effective at removing surface stains but at a rather significant cost. These kinds of toothpaste can remove tooth enamel, resulting in increased sensitivity and risks for more advanced dental problems.
Whitening mouthwashes have never been proved to be effective at improving the color of teeth. Many even contain warnings that they should not be used on teeth that are severely discolored. Mouthwashes with alcohol can also weaken dental bonding used to hold crowns and other restorations in place.
The inferior application techniques of teeth bleaching kits often result in inconsistent results along with increased tooth sensitivity and aggravation of gum tissue. In many cases, even when take-home kits whiten teeth, the results are not long-lasting.
- What Causes Teeth Get Stained?
The shade of your tooth enamel may be the result of:
- Eating habits – strongly pigmented foods such as blackberries or blueberries will stain the teeth.
- Drinking habits – strongly pigmented drinks such as colas, black tea, coffee, or red wine also stain the teeth.
- Smoking habits – nicotine causes yellow staining.
- Drugs and chemicals – some will discolor the teeth; if tetracycline is given during childhood, it will embed stains as the teeth develop. This type of staining is deep and harder to remove.
- Genetic factors – we each have an inborn tooth enamel shade.
Other factors that can discolor teeth include gum disease, tooth infection, medications, and trauma to the tooth. This type of darkening or discoloration does not respond to topical tooth whitening solutions. When the cause of your tooth discoloration is one of these factors, Dr. Marshall may recommend options such as tooth whitening with porcelain veneers … Click to go to the page of Porcelain Veneers … or dental crowns to cover the tooth and improve its appearance.
- What Choices Are There for Effective Tooth Whitening? To get it done effectively, avoid over-the-counter kits (the trays will not fit your mouth) and whitening toothpaste (some may contain abrasive ingredients that will remove enamel and end up giving you sensitive teeth). The quickest and most dramatic results come from an in-office procedure with a professional tooth whitening system. Dr. Marshall uses the Zoom! Teeth Whitening System for its speed and effectiveness.
Use of an at-home whitening kit provided by a cosmetic dentist can also be effective if you use it as directed. It takes longer, but offers you more convenience. Dr. Marshall offers a take-home kit and can have your trays custom-made for a snug fit.
- Is Tooth Whitening Feasible If You Have Sensitive Teeth?Yes. Please inform us if your teeth are particularly sensitive. If you choose to have in-office tooth whitening, we can prescribe you treatments to desensitize your teeth before the procedure.
- Could the Tooth Whitening Agent Damage My Teeth?There are no recorded instances of irreversible or structural damage caused by any tooth whitening methods. You may experience temporary tooth sensitivity, but that is not damaging to the tooth — it just feels a bit uncomfortable.
- How Quickly Are Tooth Whitening Results Visible?You will see immediate results from your in-office tooth whitening. At-home whitening is slower to show results and depends on how often you do the treatment and how consistently.
