What Makes Laser Teeth Whitening Different?
Unlike store-bought strips or toothpaste, laser teeth whitening uses professional-grade gel and focused light technology to achieve unparalleled results. The whitening gel usually contains hydrogen peroxide or carbamide peroxide that breaks down deep stains when activated with a specialized laser.
This process makes laser whitening more efficient than at-home kits. It also means you’ll see results much faster, sometimes several shades whiter in just one appointment!
How the Whitening Gel Works on Stains
The gel is the real hero of teeth whitening. Peroxide molecules in the gel penetrate the enamel’s tiny pores. Once inside, they react with stain-causing molecules from diet or smoking.
The chemical reaction breaks apart these darker molecules into smaller, less pigmented ones. As a result, teeth look brighter and cleaner.
However, without the laser’s energy, this process can be slower. The laser speeds things up by boosting the reaction.
Why the Laser Matters
Think of the laser as a catalyst. It doesn’t whiten your teeth by itself, but it accelerates the peroxide reaction. The light energy activates the gel, producing oxygen molecules that scrub away stains more effectively.
This is why professional laser teeth whitening can give noticeable results in one session, while take-home kits may take weeks. The laser ensures a more powerful and targeted treatment, customized to your needs.
Safety and Sensitivity Considerations
One of the most common questions about laser teeth whitening is whether it damages enamel. The good news is, when performed by a dental professional, it’s considered safe. Dr. Ragsdale carefully protects your gums and monitors the gel’s strength.
Some people may experience temporary tooth sensitivity after treatment. This happens when peroxide passes through the enamel and reaches the dentin layer. Luckily, the sensitivity usually fades within 24 to 48 hours.
How Long Do Results Last?
Laser teeth whitening doesn’t last forever, but it can keep your smile bright for months or even years with good habits. Avoiding dark drinks, quitting smoking, and practicing excellent oral hygiene all help.
Dr. Ragsdale may also recommend touch-up treatments to maintain results. Compared to other methods, laser whitening often delivers longer-lasting brightness.
