Over the counter bleaching
Over-the-counter bleaching uses peroxide gel, and its result depends on the stain, concentration, fit, and contact time.
The short answer
Peroxide molecules diffuse through enamel and dentin and break down some colored compounds. They do not whiten fillings, crowns, veneers, or exposed root surfaces in the same way as natural teeth.
What is the direct answer?
What does this question mean?
Read the product directions, keep gel off the gums, and stop if burning or marked sensitivity develops. A dentist can examine the cause of discoloration and make a tray or plan that accounts for restorations and gum recession.
What can you do next?
Seek dental care before bleaching if you have cavities, cracked teeth, gum disease, unexplained pain, or a darkened tooth. These conditions can make bleaching uncomfortable or mask a problem.
When should you seek dental care?
Ask whether the stain is likely to respond, whether existing restorations will mismatch, and how to manage sensitivity or gum contact.
Frequently asked questions
Can home care replace a dental examination?
Home care can support comfort and plaque control, but it cannot diagnose or treat every cause of dental symptoms.
What changes the right treatment?
The cause, affected tissues, symptoms, restorations, and examination findings determine the next step.
