A brighter smile is one of the most requested cosmetic dental treatments, but it’s fair to wonder whether whitening your teeth comes with any downsides. Here’s what’s actually going on beneath the surface.

How Teeth Whitening Works

Most professional whitening treatments use a peroxide-based gel that breaks down stains within the enamel and just beneath it. According to the American Dental Association’s MouthHealthy resource, whitening is generally considered safe when performed under professional supervision, since a dentist can control the concentration of the whitening agent and monitor your teeth and gums throughout the process.

Why Professional Supervision Matters

Store-bought whitening kits use lower concentrations of whitening agents and aren’t customized to your mouth, which can lead to uneven results or irritation if trays don’t fit properly. A dental office can also check for any underlying issues, like cavities or gum recession, before starting treatment, since whitening tends to work best and most comfortably on healthy teeth and gums.

Common Side Effects

Temporary tooth sensitivity is the most common side effect of whitening, along with occasional gum irritation if the whitening gel comes into contact with soft tissue. Both typically resolve within a day or two after treatment.

Who Should Be Cautious

Whitening isn’t recommended for everyone. Patients with untreated cavities, significant gum disease, or certain dental work like crowns and veneers in visible areas (since whitening won’t change the color of these restorations) should talk to their dentist before starting treatment.
