Yes, with professional evaluation. Dentists assess sensitivity and gum health before treatment, using desensitizing agents or lower-concentration gels when needed. Active gum disease should be treated first. Personalized protocols minimize discomfort while protecting soft tissues and enamel.

Professional whitening only lightens natural tooth enamel and will not change the color of restorations. Discuss restorative needs before treatment - your dentist may recommend replacing or matching crowns and veneers after whitening to ensure consistent shade.

Most patients achieve desired results in one in-office session or a short series of take-home trays over one to two weeks. Severity of staining, desired shade change, and sensitivity dictate session count - your dentist will create a tailored schedule.

Avoid staining foods and drinks like coffee, red wine, and tobacco for at least 48 hours and use a straw when possible. Maintain excellent oral hygiene, regular cleanings, and occasional touch-ups with at-home trays or whitening toothpaste as recommended.

Temporary tooth sensitivity and mild gum irritation are common but short-lived. Sensitivity usually subsides within days; using desensitizing products and professional techniques reduces discomfort. Report prolonged pain or gum issues so your dentist can adjust the treatment plan.
