Teeth whitening cost in Chennai varies depending on the whitening system, the extent of staining, and whether a take-home maintenance plan is included. A personalised cost estimate is provided after your consultation.

Some patients experience mild, temporary sensitivity after whitening — this is normal and typically resolves within 24–48 hours. At Aligning Dentistry, we assess your sensitivity history before treatment and adjust our protocol accordingly to minimise discomfort.

Results vary by individual and depend on dietary habits and lifestyle factors such as coffee, tea, and tobacco use. With sensible maintenance, results from professional whitening can last considerably longer than home treatments.

Home whitening products are generally less effective because they contain lower concentrations of active agents. Professional whitening delivers faster, more uniform, and more significant results — and is conducted under clinical supervision.

Yes, in most cases. We use sensitivity-managed protocols and appropriate whitening agents for patients who are prone to sensitivity. This is assessed and planned for before your treatment begins.

Salon or beauty-clinic whitening is not supervised by a registered dental professional, and the agents used are typically much weaker due to regulatory restrictions. Clinical whitening is safer, more effective, and includes a proper dental assessment before treatment.
