Professional teeth whitening

Teeth whitening options to brighten your natural smile safely and predictably.

Over time, coffee, tea, wine, tobacco, certain foods, and the natural aging process can cause teeth to become stained or discolored. Professional teeth whitening can help brighten your smile, and we'll discuss whether in-office or take-home whitening is the best option based on your goals and oral health needs.

Why whitening helps

A brighter smile with professional guidance.

Whitening works best when your teeth and gums are healthy first. We check for dental work, sensitivity, and shade goals before recommending treatment.

Brighten natural enamel

Professional whitening can lift many common stains from natural tooth structure.

Choose the right option

We can compare in-office and take-home whitening based on your timeline and goals.

Plan around dental work

We identify fillings, crowns, or veneers that will not whiten before you start.

Manage sensitivity

If your teeth are sensitive, we can discuss ways to reduce discomfort before and after whitening.

Set realistic expectations

We explain which stains usually respond to whitening and which concerns may need another option.

Maintain your result

After whitening, we review habits and touch-up timing that can help your smile stay brighter.

Whitening details

What to know before whitening your teeth.

Whitening can brighten natural teeth, but it does not change the color of crowns, veneers, fillings, or bridges.

Whitening may help with

  • Coffee, tea, or wine staining
  • Tobacco-related surface discoloration
  • Natural shade darkening over time
  • Pre-event smile refreshes
  • Uneven brightness when teeth are otherwise healthy

We check first

  • Cavities or gum inflammation
  • Tooth sensitivity
  • Existing fillings, crowns, veneers, or bridges
  • Whether stains are internal or external
  • Your desired shade and timing

Questions patients ask

Teeth whitening FAQs

These answers are general. We will check your teeth and explain what whitening can realistically do for your smile.

Does whitening work on crowns or fillings?

No. Whitening changes natural tooth structure, not crowns, veneers, bridges, or composite fillings.

Should I get a cleaning before whitening?

Often, yes. A cleaning removes surface buildup and helps us check that your teeth and gums are ready.

Can whitening cause sensitivity?

Some patients notice temporary sensitivity. We will discuss your history and ways to manage sensitivity.

How long do whitening results last?

Results vary based on diet, habits, home care, and maintenance. Coffee, tea, wine, and tobacco can stain teeth again over time.
