Teeth Whitening

Professional teeth whitening is a procedure that removes or reduces staining from enamel caused by external factors (coffee, tea, red wine, smoking, food with strong dyes). The goal is a brighter, more even smile appearance, while understanding that each result is individual.

The procedure is based on peroxide agents that break down pigment molecules and gradually lighten the tooth. Since each tooth is different, we always assess the starting condition before whitening and recommend the approach that makes most sense for you.

How whitening works

Whitening agents are based on active ingredients such as carbamide peroxide and hydrogen peroxide. Peroxide compounds bind to molecules that cause staining, break them down and gradually lighten the tooth color. The final color also depends on natural tooth properties, such as enamel thickness, wear and previous dental procedures.

What whitening can and cannot do

• Whitening affects natural tooth tissue, not fillings, crowns or ceramic and composite veneers. After whitening, adjustment of aesthetic restorations may be necessary.
• Whitening typically does not lighten exposed tooth necks with gum recession, as there is a different surface structure.
• We whiten healthy teeth. Cavities must be treated and any endodontic treatments completed before starting.

Safety and side effects

With properly performed procedure and following instructions, the risk of permanent enamel damage is minimal. Possible side effects are usually temporary:

• temporary tooth sensitivity (often resolves on its own; sensitive toothpastes or protective coatings help),
• gum irritation or temporary damage if gel contacts soft tissue,
• unpleasant taste or nausea if a small amount of gel is swallowed.

How long does the effect last

The duration of the effect depends on habits (smoking, coffee, tea, hygiene) and starting color. On average the effect lasts about five years, some less, others more.

Whitening methods

In-office whitening

In-office whitening is performed under dentist supervision. We first protect the gums and soft tissues, then apply whitening gel to the teeth. The gel works for about 20 minutes, and we can apply it up to three times in one visit.

Advantages:

• fast effect and visible results after visit,
• precise procedure control and tissue protection.

Specifics and what to watch for:

• visit requires longer keeping mouth open,
• sensitivity may be more pronounced because higher concentrations are used.

For a more stable result, we recommend avoiding food and drinks with strong dyes for one month.

At-home whitening (with custom trays)

For at-home whitening, we first make a digital scan of teeth. Based on the scan, a dental technician creates thin, precisely fitting trays. In the evening after brushing teeth, apply a small amount of gel into the tray grooves, place the tray on teeth and sleep with it.

Key instructions:

• immediately remove gel that is squeezed out of tray from gums,
• trays should be in mouth for maximum eight hours,
• in the morning clean trays with brush, soap and water; then brush teeth again,
• avoid strong dyes in food and drinks during and one month after whitening.

Whitening is not necessary every night. How many times the procedure needs to be repeated depends on the individual and degree of staining. You can store the trays and later purchase just gel to refresh the color.
