My teeth won t whiten
Teeth may not whiten when discoloration is internal, caused by an enamel defect, or belongs to a restoration.
The short answer
Teeth may not whiten when discoloration is inside the tooth, comes from an enamel defect or medication, or belongs to a restoration rather than natural enamel.
What is the direct answer?
What does this question mean?
Peroxide acts mainly on stain molecules in natural tooth structure. It cannot bleach ceramic or composite restorations, and a single dark tooth may have an internal problem.
What can you do next?
Stop repeating whitening applications until the cause is identified. Examination, shade comparison, cleaning, pulp testing, or a restorative option may be needed.
When should you seek dental care?
Seek care for one darkening tooth, trauma, pain, or persistent sensitivity. Swelling, fever, pus, or trouble opening the mouth warrants prompt assessment.
What should you ask the dentist?
Is this surface stain, intrinsic discoloration, or a mismatched restoration, and which option preserves the most tooth structure?
