What is the direct answer?
Strawberries do not provide a controlled whitening treatment; their acids can soften enamel while fruit residue can remain around the gumline.
Strawberries contain organic acids and sugars. Rubbing or holding mashed fruit on teeth does not selectively remove intrinsic colour, calculus, or stains inside enamel and dentine, and abrasive mixtures can add mechanical wear.

Eat fruit as food rather than using it as a whitening paste, rinse with water afterward, and wait before brushing if your mouth is acidic. For a shade change, have stains and restorations assessed before choosing a peroxide-based method.
What can you do next?

Ask whether your colour change is external stain, intrinsic shade, decay, or a restoration. Ask which whitening method and concentration fit your enamel and gum health.
When should you seek dental care?
Arrange care for sensitivity, enamel wear, bleeding gums, or discolouration that affects one tooth. A dark tooth after trauma may need pulp assessment rather than cosmetic treatment.
Seek prompt assessment for facial swelling, fever, or difficulty swallowing or breathing.
What should you ask the dentist?
Ask whether your colour change is external stain, intrinsic shade, decay, or a restoration. Ask which whitening method and concentration fit your enamel and gum health.
Ask which examination findings change the diagnosis and what the alternatives, expected steps, and follow-up would be.
