First, establish what is causing the discoloration
Surface stains, changes within a tooth and the color of an existing restoration are different problems. The dentist examines your teeth and gums before recommending an approach. A tooth that has become unusually dark deserves an assessment, particularly if it has been injured or is causing symptoms.
Whitening works on natural tooth structure. Crowns, veneers and tooth-colored fillings do not respond in the same way. If those restorations are visible when you smile, discuss how the final shades will fit together.
Choose an approach you can use correctly
Professional whitening may involve treatment in the office, dentist-directed trays used at home, or another appropriate approach. The choice depends on your findings, preferences and the instructions you can follow. Ask what the proposed system involves rather than assuming all professional whitening is the same.
More product or longer application is not necessarily better. Follow the prescribed amount, wearing time and treatment duration. Tell the dentist if you have used whitening products recently so that your plan accounts for that exposure.
Sensitivity and gum irritation
Temporary sensitivity and gum irritation can occur. Discuss existing sensitivity before starting, and ask what to do if discomfort develops. The dentist may recommend a change in timing or another approach. Persistent or localized pain should be assessed.
Do not continue a treatment simply to meet a deadline if it is causing a problem. A wedding or other event is worth mentioning when planning, but results and comfort cannot be guaranteed for a particular date.
Plan the result and its maintenance
Ask what change is realistic for your starting shade and whether any teeth are likely to respond differently. If new restorations are also planned, coordinate their timing and shade selection with the dentist.
Whitening is not permanent. Habits and natural changes can affect the shade over time. Ask about appropriate maintenance, the cost of any follow-up products and whether another treatment would better address your concern.
Questions patients ask
Will whitening lighten a crown?
Existing crowns and other restorations do not lighten like natural teeth. Discuss shade differences before starting.
Is sensitivity a reason to avoid whitening?
It is a reason to discuss the plan first. The dentist can assess its cause and explain whether whitening is appropriate.
How white will my teeth become?
The response varies with the starting shade and cause of discoloration. Your examination provides a better basis for expectations than an illustrative photograph.
