Will whitening make my crowns lighter too?
No. Restorations do not whiten like natural teeth, so colour differences need planning.
Before choosing treatment, start with what worries you
Cheonan teeth whiteningDo you want a brighter smile without making sensitive teeth worse?
You may notice yellowing in photographs or feel that whitening products have made little difference. If your teeth already react to cold, stronger products can feel like a risk rather than an answer. Start by understanding the cause of the colour and whether your visible teeth are natural teeth, fillings or crowns.
You can take time to understand your options before deciding.
01 / The questions behind the treatment name01 02 03
You deserve to understand what this means for your life.
Can sensitive teeth still be treated?
The cause and severity of sensitivity should be assessed before choosing a method.
Why is only one tooth dark?
Previous trauma, root treatment or other changes may require a different approach from general whitening.
02 / Benefits and burdens
Benefits and burdens
What may improve
Whitening can improve some natural-tooth discolouration without covering the tooth with a veneer.
What to weigh up
Sensitivity, gum irritation and uneven responses can limit the result.
The question that helps you choose
Identify the cause of the colour and coordinate natural teeth with existing restorations.
03 / Make sense of your own situation01 02 03
What changes the choice of treatment?
Check the source of the colour
Surface staining and changes within a tooth are not the same problem. A single dark tooth, a previous injury or a root-treated tooth may require a different assessment from general yellowing. Gum disease, decay and existing sensitivity should be considered before deciding whether whitening is appropriate.
Set a realistic shade goal
Natural teeth and restorations do not respond in the same way. A crown or filling may remain a different shade after surrounding teeth become lighter. Discuss the whole visible smile and whether any later restoration changes would be needed. A photograph or shade chart cannot guarantee a particular individual result.
Balance the method with comfort and maintenance
The method and schedule should fit your dental condition and tolerance. Sensitivity or gum irritation can occur, and using more product does not necessarily improve the result safely. Ask what symptoms should prompt a pause or review. Colour can change again over time, so discuss maintenance without assuming an unlimited permanent effect.
Benefits and burdens
Potential benefits
Some colour concerns may be addressed without preparing the tooth for a restoration.
An assessed plan can distinguish removable stain from deeper colour changes.
Benefits and burdens
Limitations and risks
Not every type of discolouration responds equally.
The result is not permanent, and existing crowns or fillings may remain a different shade.
Assess suitability before whitening
Whitening changes tooth shade, not tooth shape or every existing restoration. Method, response and sensitivity vary.
- 01
Assess shade and suitability
Review baseline shade, restorations and oral condition to discuss the method and expectations.
- 02
Protect and apply
Protect soft tissues and apply material according to the selected method.
- 03
Complete the application
Follow the application process specified for the selected method and material, then remove the whitening material. Shade change and the time required vary between individuals.
- 04
Review shade and comfort
Assess shade under comparable lighting, discuss sensitivity and plan aftercare.

04 / Treatment and everyday life
Plan for the time between appointments, too.
Follow the supplied method and stop to seek advice if symptoms exceed the agreed guidance.
Avoid adding multiple whitening products or extending treatment without advice.
Costs, time and follow-up
Ask for a plan you can understand and manage.
What does the estimate include?
Ask which examinations, temporary stages, final treatment, retainers or maintenance, and repairs are included. The scope depends on your findings and chosen plan. A headline price cannot describe every person’s total cost. Ask how a change in the plan would be explained and agreed before it goes ahead.
Clinic fee information →How will visits fit into my life?
Bring previous records if you have them, your medication list and the practical limits on travel or time off work. Ask what each visit is for, what may change the timetable, and who to contact if something feels wrong. You do not need to promise to start treatment at the first conversation.
Location and visiting information →05 / Questions worth asking again
Uncertainty is a good reason to ask another question.
Is a stronger product always better?
No. The appropriate product and schedule depend on the condition of the teeth and risk of irritation.
Can whitening replace treating decay?
No. Disease and damaged restorations need their own assessment and treatment.
How white can my teeth become?
An exact shade cannot be guaranteed. Discuss realistic change from your starting colour.
Should I whiten before a new front crown?
Colour planning should be coordinated so the final restoration matches the intended natural-tooth shade.
